Accounts Payable Policy: What to Include, Procedures, and Example

Accounts payable teams often manage invoices, approvals, vendor records, payment schedules, and exceptions across disconnected workflows. Without a formal AP policy, teams may rely on informal approvals, inconsistent invoice validation, unclear authorization rules, and undocumented exceptions.

These gaps can increase the risk of duplicate payments, vendor disputes, delayed approvals, weak audit trails, compliance issues, and inaccurate financial reporting.

A well-structured accounts payable policy solves this by creating a formal control framework for invoice processing, approval authority, payment execution, dispute resolution, record retention, and compliance monitoring. For growing organizations, it supports scalable AP operations, stronger internal controls, and a more reliable financial close.

What Is an Accounts Payable Policy?

An accounts payable policy is a formal document that defines how a company manages supplier invoices, payment approvals, vendor records, payment execution, exception handling, documentation, and related financial controls.

It sets the rules for the full invoice-to-payment cycle. This includes how invoices are received, how vendor information is verified, who approves payments, how invoices are matched to purchase orders, when payments are scheduled, and how AP records are retained for audit and reporting purposes.

A well-written AP policy should answer questions such as:

• Which invoices require purchase orders?
• Who can approve invoices and up to what amount?
• What documents are required before payment?
• How should duplicate invoices or disputed charges be handled?
• Which payment methods are allowed?
• How often should vendor records be reviewed?
• What evidence must be retained for audit purposes?

Who Uses an Accounts Payable Policy?

An AP policy extends beyond the accounts payable function. It applies to every team involved in purchasing, invoice approvals, vendor management, tax documentation, payment controls, and financial reporting.

Typical users include:

• Accounts payable teams that process, validate, code, approve, and pay invoices.
• Procurement teams that create purchase orders and manage vendor relationships.
• Department managers who approve expenses and confirm goods or services received.
• Finance and accounting teams that manage accruals, reconciliations, reporting, and close activities.
• Tax teams that review vendor documentation, tax forms, withholding rules, and reporting obligations.
• Legal teams that review contract terms, supplier agreements, and dispute procedures.
• Internal audit and compliance teams that test controls and review policy adherence.

The policy should be written in a way that each group understands its role, approval responsibility, and documentation requirement.

How an AP Policy Differs from AP Processes and Procedures

An accounts payable policy defines the rules. AP procedures explain the steps used to follow those rules.

For example, a policy may state that all invoices above a certain amount require department head approval. The procedure explains how that approval is requested, where it is recorded, what system is used, and what happens if the approver does not respond.

In simple terms:

Area	Meaning	Example
AP Policy	Defines the rule	Invoices above $10,000 require finance director approval
AP Procedure	Explains the steps	AP routes the invoice through the approval workflow and tracks approval evidence
AP Process	Shows the workflow	Invoice receipt, validation, matching, approval, payment, posting, reconciliation

The policy should stay stable enough to support governance, while procedures may change as systems, teams, and workflows change.

How an Accounts Payable Policy Fits into the AP Workflow

The AP policy acts as the control layer across the full accounts payable workflow. It guides what should happen at each stage and defines who is accountable.

A typical AP workflow includes:

1. Invoice receipt
2. Vendor and invoice validation
3. Purchase order or receiving match
4. General ledger coding
5. Approval routing
6. Exception resolution
7. Payment scheduling
8. Payment execution
9. Accounting system posting
10. AP reconciliation and record retention

The policy should connect directly to these stages. This helps employees understand that AP policy is not just a finance document. It is a working control framework for daily invoice and payment activity.

Why Are Accounts Payable Policies and Procedures Important?

Accounts payable policies and procedures help standardize payment operations, reduce transaction risk, strengthen audit readiness, and improve visibility into organizational spend.

Without a defined policy, AP decisions often rely on individual discretion. This may be manageable for low invoice volumes, but it becomes increasingly risky as vendor counts, legal entities, approval layers, payment methods, and transaction complexity grow.

1. Maintaining Consistency Across AP Operations

A clear AP policy helps teams process invoices the same way across departments, locations, entities, and business units.

Consistency matters as small differences in invoice handling can create large downstream issues. One team may approve invoices by email, another may approve them verbally, while another may require purchase order matching. These gaps make it harder to monitor controls, track liabilities, and prepare accurate reports.

A standardized policy helps define:

• Required invoice fields
• Supporting document requirements
• Approval routing rules
• Payment timing expectations
• Exception handling steps
• Record retention rules

2. Strengthening Financial Controls and Spending Visibility

An accounts payable policy strengthens financial controls by defining who can approve spending, what evidence is required, and how payments are authorized.

It also improves spending visibility. When invoices are coded consistently, matched correctly, and approved through defined workflows, finance teams can better analyze spend by vendor, department, cost center, project, location, and category.

A strong policy should connect AP activity to broader finance goals such as:

• Cash flow planning
• Budget control
• Working capital management
• Month-end close accuracy
• Vendor spend analysis
• Payment forecasting
• Audit preparation

3. Preventing Fraud, Duplicate Payments, and Unauthorized Spending

Weak AP controls can create opportunities for duplicate payments, fake vendors, inflated invoices, payment diversion, and unauthorized purchases.

An AP policy helps reduce these risks by requiring:

• Vendor verification before payment
• Segregation of duties
• Approval limits based on role and amount
• Purchase order matching where applicable
• Duplicate invoice checks
• Bank account change validation
• Supporting documents for non-PO invoices
• Exception review before payment release

The need for stronger AP controls is significant. ACFE estimates that organizations lose 5% of revenue each year to fraud, making approval controls, vendor validation, and payment authorization critical parts of AP governance. The policy should clearly state that no single employee should control vendor creation, invoice approval, payment authorization, and bank account changes without review.

4. Supporting Regulatory Compliance and Audit Readiness

Accounts payable affects tax reporting, vendor documentation, financial statements, internal controls, and audit evidence. A policy helps companies maintain records that can be reviewed and tested.

The policy should define:

• Required vendor tax forms
• Invoice documentation standards
• Record retention periods
• Approval evidence requirements
• Payment authorization records
• Reconciliation procedures
• Audit trail expectations

5. Improving Vendor Relationships and Payment Reliability

Vendors expect predictable payment behavior. A clear AP policy helps vendors understand invoice submission requirements, payment timelines, dispute resolution steps, and documentation standards.

This reduces back-and-forth communication and lowers the risk of missed discounts, late payment penalties, service disruptions, and vendor dissatisfaction.

For example, the policy may specify that invoices must include a valid purchase order number, the supplier’s legal name, the invoice date, tax details, payment terms, and remittance information. When vendors know these requirements upfront, invoice exceptions decrease.

6. Reducing the Risks of Informal AP Practices

Informal AP practices often develop when employees try to move quickly. Examples include approving invoices through chat messages, paying vendors before validation, bypassing purchase orders, or creating vendors without proper review.

These practices may seem efficient in the moment, but they create long-term control issues.

An AP policy reduces these risks by defining what is allowed, what is prohibited, and how exceptions must be approved. It gives AP teams the authority to reject incomplete invoices, pause suspicious payments, and escalate policy violations.

What Should an Accounts Payable Policy Include?

An accounts payable policy should include the rules, responsibilities, controls, documentation requirements, and review procedures that govern the complete invoice-to-payment cycle.

The policy should be practical enough for daily use and detailed enough to support finance controls, audits, and compliance reviews.

1. Policy Purpose, Scope, and Objectives

The policy should begin with a purpose statement. This explains why the policy exists and what it is meant to control. The scope should define which entities, departments, employees, vendors, invoice types, and payment categories are covered.

A strong purpose statement may cover:

• Accurate and timely invoice processing
• Controlled vendor payments
• Prevention of unauthorized spending
• Support for financial reporting
• Compliance with tax and accounting requirements
• Consistent treatment of invoices, exceptions, and payments

2. Policy Ownership and Departmental Responsibilities

The policy should assign ownership clearly. Usually, the finance or accounting department owns the AP policy, while procurement, tax, legal, operations, and business departments share responsibility for specific activities.

Common responsibilities include:

• Finance: AP governance, payment controls, reconciliations, reporting, and policy updates.
• AP team: Invoice processing, validation, coding, approval routing, exception tracking, and payment preparation.
• Procurement: Purchase orders, supplier onboarding support, contract alignment, and procurement compliance.
• Department heads: Invoice review, goods or service confirmation, and spending approval.
• Tax: Vendor tax documentation and reporting requirements.
• Legal: Contract terms, dispute clauses, and high-risk vendor arrangements.
• Internal audit: Control testing and policy compliance review.

3. Segregation of Duties and Authorization Limits

Segregation of duties is one of the most important AP controls. The policy should prevent a single person from controlling multiple high-risk stages of payment.

For example:

• The employee who creates a vendor should not approve payments to that vendor.
• The employee who approves an invoice should not be the only person releasing payment.
• The employee who changes vendor bank details should not process the next payment without review.

Authorization limits should be documented by role, department, amount, and payment type.

4. Purchase Order and Procurement Requirements

The policy should define when purchase orders are required and when exceptions are allowed.

It should cover:

• PO requirements by spend category
• Approval requirements before purchase commitment
• Rules for blanket purchase orders
• Treatment of contract-based invoices
• Requirements for receiving documents
• Handling of non-PO invoices
• Consequences for repeated PO bypasses

5. Vendor Onboarding and Master Data Controls

Vendor master data is one of the highest-risk areas in AP. The policy should define how vendors are created, reviewed, updated, and deactivated.

It should include controls for:

• Vendor identity verification
• Tax documentation collection
• Bank account validation
• Duplicate vendor checks
• Sanction or restricted-party screening where applicable
• Approval of new vendors
• Review of vendor bank account changes
• Deactivation of inactive vendors

Vendor record changes should always leave an audit trail showing who requested, reviewed, approved, and completed the change.

6. Invoice Receipt, Validation, and Coding Standards

The policy should define approved invoice receipt channels. This may include a dedicated AP email inbox, supplier portal, electronic invoice exchange, or approved document intake system. Coding standards should define how invoices are assigned to general ledger accounts, cost centers, departments, projects, locations, and entities.

Invoice validation rules should specify required fields such as:

• Supplier legal name
• Invoice number
• Invoice date
• Purchase order number, if applicable
• Description of goods or services
• Tax amount and tax registration details
• Payment terms
• Currency
• Remittance details
• Total invoice amount

7. Invoice Matching and Approval Requirements

The policy should state when two-way or three-way matching is required.

• Two-way matching compares the invoice with the purchase order.
• Three-way matching compares the invoice with the purchase order and receiving document.

The policy should also define matching tolerances. For example, small differences in freight, tax, quantity, or unit price may be allowed within defined thresholds. Differences outside those thresholds should require review and approval.

Approval requirements should be based on invoice amount, department, vendor type, expense category, and risk level.

8. Dispute, Discrepancy, and Exception Handling

Invoice exceptions should not be handled informally. The policy should define how disputes and discrepancies are recorded, assigned, escalated, and resolved. The policy should also define who can approve payment after an exception is resolved.

Common exceptions include:

• Price mismatch
• Quantity mismatch
• Missing purchase order
• Missing receiving confirmation
• Incorrect tax
• Duplicate invoice
• Invalid vendor details
• Contract rate mismatch
• Goods not received
• Services not completed

9. Payment Terms, Methods, and Scheduling Rules

The policy should define approved payment methods and scheduling rules.

The policy should specify when each method is allowed. For example, wires may require additional approval because they carry higher risk and are harder to recover once released.

Payment scheduling rules should align with vendor terms, cash flow plans, discount opportunities, and internal payment runs.

Common payment methods include:

• ACH
• Wire transfer
• Check
• Virtual card
• Corporate card
• International transfer

10. Early Payment Discount Guidelines

Early payment discounts can reduce costs, but only when they are managed carefully.

The policy should define:

• Who can approve early payments
• Which discount terms qualify
• How discounts are calculated
• Whether discounts override normal payment schedules
• How missed discounts are tracked
• How discounts are reported to finance leadership

11. Tax Documentation and Reporting Requirements

The AP policy should define tax documentation requirements before vendors are paid. Requirements vary by country, vendor type, payment category, and reporting obligation. AP should coordinate with the tax team when vendor type, geography, or payment category creates additional reporting requirements.

This section may cover:

• Tax identification forms
• Withholding tax documentation
• GST, VAT, or sales tax information
• Tax exemption certificates
• Year-end vendor reporting
• Cross-border tax review
• Invoice tax validation

12. Write-Off and Unclaimed Payment Procedures

The policy should explain how small balances, expired liabilities, stale checks, vendor credits, and unclaimed payments are reviewed.

Write-off procedures should define:

• Eligible balance types
• Review frequency
• Approval authority
• Documentation required
• Accounting treatment
• Reporting requirements
• Treatment of unclaimed property where applicable

13. Record Retention and Audit Trail Requirements

The policy should specify which AP records must be retained and for how long. Retention periods may vary by jurisdiction, tax rule, contract requirement, and industry.

Records may include:

• Invoices
• Purchase orders
• Receiving documents
• Contracts
• Approval logs
• Payment confirmations
• Vendor tax forms
• Bank account validation records
• Exception notes
• Reconciliation evidence
• Policy approvals and version history

14. Account Reconciliation and Financial Reporting

Accounts payable records must reconcile with the general ledger and financial statements. The policy should define reconciliation frequency, ownership, review standards, and documentation requirements. Clear reconciliation rules help finance teams avoid misstated liabilities and close delays.

This section should cover:

• AP subledger to general ledger reconciliation
• Vendor statement reconciliation
• Accrued liability review
• Aged payable review
• Unapplied credit review
• Payment clearing account review
• Month-end cutoff procedures

15. Risk Control Matrix and Performance Metrics

A strong AP policy should include a control view of the process. This is often missing in generic AP policies.

A risk control matrix links AP risks to specific controls, owners, evidence, and review frequency.

AP Risk	Control	Owner	Evidence
Duplicate payment	Duplicate invoice check before payment	AP team	Exception report
Unauthorized payment	Approval matrix by amount and role	Finance	Approval log
Fake vendor	Vendor onboarding verification	Procurement and AP	Vendor setup checklist
Incorrect GL coding	Coding review for high-value invoices	Accounting	Coding approval record
Payment fraud	Bank change validation	AP manager	Bank change approval trail

The policy should also define AP performance indicators such as invoice cycle time, exception rate, duplicate payment rate, approval delay, early payment discount capture, on-time payment rate, and unresolved vendor disputes.

16. Policy Review and Version Control

The policy should not remain static for years. It should be reviewed at a defined interval and updated when business conditions, systems, regulations, or risks change.

Version control should include:

• Policy owner
• Effective date
• Review date
• Approved changes
• Approver name and role
• Summary of revisions
• Superseded versions

Core Accounts Payable Procedures from Invoice Receipt to Payment

Accounts payable procedures convert policy rules into daily operating steps. They should be clear enough that AP staff, approvers, auditors, and new employees can understand how invoices move from receipt to payment.

1. Receive and Register Supplier Invoices

All supplier invoices should be received through approved channels. Invoices sent to personal inboxes, informal chats, or unauthorized channels increase the risk of delays and missed controls.

Once received, invoices should be logged with basic details such as supplier name, invoice number, invoice date, amount, currency, purchase order number, receipt date, and processing status.

2. Validate Vendor and Invoice Information

Before an invoice is approved for payment, AP should confirm that the vendor exists in the approved vendor master and that invoice details are complete. Any invoice with missing or suspicious information should be placed on hold until resolved.

Validation should include:

• Vendor name and address
• Invoice number and date
• Bank or remittance information
• Tax details
• Currency
• Payment terms
• PO number, if applicable
• Invoice total and line-item details

3. Match Invoices with Purchase Orders and Receiving Documents

For PO-based invoices, AP should match invoice details with the purchase order and receiving documents. Invoices outside tolerance should be routed for review before approval.

Matching should verify:

• Vendor name
• PO number
• Item description
• Quantity
• Unit price
• Tax
• Freight or additional charges
• Goods receipt or service confirmation

4. Code Invoices to the Correct General Ledger Accounts

Invoice coding should follow the company’s chart of accounts and cost allocation rules. Incorrect coding can affect department budgets, tax reporting, financial statements, and management reporting.

Coding rules should define how invoices are assigned to:

• GL accounts
• Cost centers
• Departments
• Projects
• Locations
• Legal entities
• Expense categories

5. Route Invoices Through the Approval Hierarchy

Invoices should be routed according to the approval matrix. Approval should be based on amount, department, expense type, legal entity, and policy requirements.

The procedure should define what happens when:

• An approver is unavailable
• Approval is delayed
• The invoice is disputed
• The invoice exceeds authority limits
• A higher-level approval is required

Approval evidence should be captured in a system or documented workflow, not stored only in email threads.

6. Resolve Invoice Exceptions and Disputes

Exceptions should be logged and assigned to the correct owner. AP should not release payment until the issue is resolved and approved. This gives finance teams visibility into recurring issues, such as vendors submitting invoices without purchase orders or departments delaying approvals.

The procedure should define:

• Exception category
• Responsible owner
• Required supporting documents
• Escalation path
• Timeframe for resolution
• Approval required after resolution

7. Schedule and Authorize Payments

Approved invoices should be scheduled according to vendor terms, payment runs, cash flow requirements, and discount opportunities. High-value payments should require additional authorization.

Before payment release, AP should confirm:

• Invoice approval is complete
• Vendor bank details are verified
• Payment amount is correct
• Duplicate checks are complete
• Payment method is approved
• Supporting documents are attached

8. Record Payments in the Accounting System

Once payment is executed, it should be recorded in the accounting or ERP system. Payment records should include transaction date, amount, vendor, invoice number, payment method, bank account, and reference number.

Accurate payment posting supports cash reporting, bank reconciliation, vendor statements, and month-end close.

9. Reconcile Accounts Payable Records

AP records should be reconciled regularly to confirm that liabilities, payments, credits, and vendor balances are accurate.

Reconciliations may include:

• AP subledger to general ledger
• Vendor statements
• Accrued expenses
• Payment clearing accounts
• Open invoice reports
• Aged payables
• Unapplied credits

10. Retain Supporting Documents for Audits

Every invoice should have enough documentation to prove why it was paid, who approved it, and how it was recorded.

Supporting documents may include invoices, purchase orders, receipts, contracts, approvals, exception notes, payment confirmations, and reconciliation records.

How to Create an Accounts Payable Policy and Procedures Manual

Creating an AP policy and procedures manual requires more than documenting existing steps. The goal is to identify risks, define controls, remove unclear practices, and create a policy that employees can follow in real work conditions.

Step 1: Assess the Current AP Process and Control Gaps

Start by reviewing how invoices and payments are handled today. This review helps identify where policy rules are missing, unclear, or ignored.

Evaluate:

• Invoice intake channels
• Vendor onboarding steps
• Approval delays
• Duplicate payment history
• Non-PO invoice volume
• Manual workarounds
• Payment exception trends
• Vendor data quality
• Reconciliation issues
• Audit findings

Step 2: Involve Finance, Procurement, Tax, Legal, and Operations Teams

AP policy affects multiple functions. Finance may own the policy, but other teams help define practical rules.

For example, procurement should help define PO requirements. Tax should define documentation needs. Legal should review contract-related payment terms. Operations should confirm receiving and service validation steps.

Cross-functional input helps prevent a policy that looks good on paper but fails in daily use.

Step 3: Define Policy Owners and Decision-Making Authority

The manual should name the policy owner and define who has authority to approve updates, exceptions, payment releases, write-offs, and vendor changes.

Clear decision rights reduce delays and prevent employees from escalating every exception to the wrong person.

Step 4: Map the Complete Invoice-to-Payment Workflow

Create a workflow map that shows each step from invoice receipt to payment and reconciliation. This workflow map should be included in the manual or linked from it.

The map should show:

• Process step
• Responsible role
• System used
• Required documents
• Control point
• Exception path
• Approval requirement
• Output or evidence created

Step 5: Establish Approval Hierarchies and Spending Thresholds

Approval thresholds should reflect the company’s risk appetite, budget structure, and organizational hierarchy. Approval authority should be reviewed regularly as roles, departments, and budgets change.

The approval matrix should define:

• Approval limits by role
• Department approval requirements
• Finance approval requirements
• Executive approval thresholds
• Special approval for high-risk payments
• Delegation rules
• Temporary approver rules

Step 6: Set Invoice Matching, Payment, and Control Rules

The policy manual should define matching rules, payment rules, and control checks in practical detail. These rules should be specific enough to reduce interpretation gaps.

For example:

• PO invoices require two-way or three-way matching.
• Non-PO invoices require business justification and department approval.
• Vendor bank changes require independent verification.
• Invoices above a certain amount require finance review.
• Payments are released only during approved payment runs.
• Duplicate invoice checks must occur before payment.

Step 7: Document Escalation and Write-Off Procedures

The manual should explain how unresolved invoices, disputed amounts, old balances, vendor credits, and write-offs are handled.

Escalation procedures should define who is notified, when escalation occurs, and what documentation is required.

Write-off procedures should specify approval authority, accounting treatment, and supporting evidence.

Step 8: Align the Policy with Accounting and Regulatory Requirements

The AP policy should align with the company’s accounting policies, tax obligations, internal control framework, procurement policy, contract review process, and financial reporting requirements.

This alignment prevents conflicts between departments. For example, procurement may approve a vendor contract with payment terms that AP cannot support, or AP may process tax-sensitive payments without tax review.

Step 9: Test the Policy Against Real AP Scenarios

Before final approval, test the policy against real invoice scenarios. Testing reveals whether the policy is clear, complete, and usable.

Use examples such as:

• PO invoice with price variance
• Non-PO invoice from a new vendor
• Urgent payment request
• Vendor bank account change
• Duplicate invoice submission
• International vendor payment
• Subscription renewal
• Employee reimbursement
• Old vendor credit
• Disputed service invoice

Step 10: Obtain Final Review and Management Approval

The final policy should be reviewed by finance leadership, procurement, tax, legal, operations, and internal audit where applicable.

Management approval gives the policy authority. Employees should know that the policy is not optional and that exceptions must be documented.

How Should an AP Policy Address Special Payment Situations?

Special payment situations create higher risk because they often fall outside standard invoice workflows. A good AP policy should define how these cases are handled before they occur.

Rush and Emergency Payments

Rush payments should be limited to valid business needs, such as critical service restoration, contractual deadline risk, or urgent operational requirements. The policy should require written business justification, department approval, finance approval, vendor validation, payment method approval, and post-payment documentation review before the transaction is completed. Rush payments should also be tracked separately so finance can identify departments or vendors that frequently bypass standard payment timelines.

Employee Reimbursements and Expense Reports

Employee reimbursements should be governed by clear documentation and approval rules. The AP policy should align with the company’s travel and expense policy and define eligible expenses, receipt requirements, submission deadlines, approval authority, reimbursement timelines, taxable reimbursement treatment, handling of missing receipts, and prohibited expenses. This ensures employee payments are processed consistently and supported by proper evidence.

Recurring Payments and Subscriptions

Recurring payments require periodic review because they can continue even after a service is no longer needed. The policy should assign a contract or subscription owner, track renewal dates, require periodic usage reviews, mandate approval before renewal, define cancellation procedures, validate price increases, and review inactive subscriptions. These controls help prevent spend leakage from unused, duplicate, or forgotten subscriptions.

International Vendors and Foreign Currency Payments

International payments may involve foreign exchange exposure, tax withholding, bank fees, sanctions screening, and regulatory documentation. The policy should define approved payment methods, currency conversion rules, exchange rate sources, cross-border tax review requirements, required banking information, additional approval requirements, and documentation for fees or withholding. Payments involving high-risk jurisdictions or unusual payment instructions should require additional review before release.

Non-PO and One-Time Vendor Invoices

Non-PO invoices are common, but they carry higher control risk because they are not tied to a pre-approved purchase order.

The policy should define when non-PO invoices are allowed. For example, utilities, legal fees, rent, subscriptions, emergency repairs, and certain professional services may be permitted.

One-time vendors should still go through basic validation before payment.

Duplicate, Incorrect, and Disputed Invoices

Duplicate or incorrect invoices should be placed on hold. The policy should define how AP identifies, records, and resolves these cases.

AP should check for duplicate invoice numbers, matching amounts, repeated bank details, duplicate vendor records, and similar invoice dates.

Disputed invoices should not be paid until the responsible department confirms resolution.

Expired Liabilities and Accounts Payable Write-Offs

Old AP balances, stale checks, and unclaimed payments should be reviewed periodically to keep AP records accurate and current. The policy should define the review frequency, aging thresholds, investigation owner, vendor confirmation requirements, write-off approval limits, accounting treatment, and procedures for handling unclaimed payments. This helps maintain clean AP records and supports accurate liability reporting.

Accounts Payable Policy Example and Customizable Template

The following accounts payable policy example can be customized based on company size, industry, system setup, approval structure, and regulatory environment.

Sample Purpose and Scope Statement

Purpose:

This accounts payable policy establishes the rules for receiving, validating, approving, recording, paying, reconciling, and retaining supplier invoices and related payment documents. The policy is intended to support accurate financial reporting, controlled vendor payments, timely invoice processing, and compliance with company approval and documentation requirements.

Scope:

This policy applies to all employees, departments, business units, and legal entities involved in supplier purchases, invoice approvals, vendor payments, employee reimbursements, and accounts payable recordkeeping.

Sample Roles and Responsibilities Matrix

Role	Responsibility
Accounts Payable	Receives invoices, validates details, routes approvals, prepares payments, retains documents
Procurement	Manages purchase orders, vendor onboarding support, and supplier documentation
Department Approver	Confirms goods or services received and approves valid expenses
Finance Manager	Reviews high-value invoices, payment runs, exceptions, and reconciliations
Tax Team	Reviews vendor tax documentation and reporting requirements
Legal Team	Reviews contract-related payment disputes and supplier terms
Internal Audit	Tests AP controls and policy compliance

Sample Approval and Authorization Matrix

Invoice Amount	Required Approval
Up to $2,500	Department manager
$2,501 to $10,000	Department head
$10,001 to $50,000	Department head and finance manager
Above $50,000	Finance director or CFO
Rush payments	Department head and finance approval
Vendor bank change	AP manager and finance review

Approval limits should be adjusted based on the organization’s size, risk profile, and authority structure.

Sample Invoice Processing Rules

All supplier invoices must be submitted through approved invoice channels. Invoices must include the vendor name, invoice number, invoice date, purchase order number where applicable, description of goods or services, tax details, payment terms, and total amount.

PO-based invoices must be matched against purchase orders and receiving documents before payment. Non-PO invoices require department approval and business justification.

Incomplete invoices will be returned to the vendor or placed on hold until missing information is received.

Sample Payment Policy and Schedule

Payments will be processed according to agreed vendor payment terms and company payment run schedules. Payment methods must be approved by finance.

Payment runs may be scheduled weekly, biweekly, or according to cash management requirements. High-value payments, international payments, and rush payments require additional review before release.

Early payments may be approved when they capture a valid discount or prevent business disruption.

Sample Exception and Write-Off Guidelines

Invoice exceptions must be documented and assigned to the appropriate owner. AP may not release payment for invoices with unresolved discrepancies unless finance approves an exception.

Small balances, stale checks, old credits, and expired liabilities must be reviewed periodically. Write-offs require approval based on the authorization matrix and must be supported by documentation.

Sample Record Retention Requirements

The company must retain AP records according to legal, tax, audit, and internal reporting requirements.

Retained records may include:

• Supplier invoices
• Purchase orders
• Receiving documents
• Contracts
• Approval records
• Payment confirmations
• Vendor tax documentation
• Exception notes
• Reconciliation records
• Write-off approvals
• Sample Policy Review Schedule

This policy should be reviewed at least annually or sooner if there are changes in systems, regulations, business structure, payment methods, audit findings, fraud incidents, or control requirements.

All updates must be documented with version number, effective date, summary of changes, policy owner, and management approval.
