What Is Accounts Payable? Definition, Process, Examples

Accounts payable (AP) is money a business owes suppliers for goods or services it received but has not paid.

Every business that buys on credit has accounts payable. Therefore, it appears on the balance sheet as a current liability.

Payment usually falls due in 30 to 90 days, depending on supplier terms. AP is also the name of the department and process that pay those bills.

This guide explains what accounts payable means, how debits and credits work, and what the AP process looks like.

Accounts Payable: Key Facts and Definitions

What Is Accounts Payable?

Accounts payable is the total a business owes suppliers, vendors, and creditors for purchases made on credit and not yet paid.

What are accounts payable in practice? For example, a business orders inventory, receives professional services, or buys supplies and agrees to pay later. As a result, that obligation becomes an account payable.

The supplier sends an invoice, and the business records it as a payable. Finally, when payment goes out, the payable clears.

AP also drives cash flow, supplier relationships, and financial statement accuracy. Therefore, it is one of the most important short-term liabilities a business carries.

What Does AP Mean in Business?

AP stands for accounts payable. Specifically, people use the term AP in business in three ways.

• Balance: the total owed to suppliers on a given date.
• Process: the workflow that takes an invoice from receipt to payment.
• Team: the department that records, approves, and pays supplier bills.

In accounting, accounts payable are also called trade payables. Similarly, some businesses say bills payable for the same obligations.

How Does an Account Payable Arise?

An account payable arises when a vendor delivers goods or services before getting paid. Specifically, the vendor extends trade credit, usually on terms such as net 30 or net 60.

Net 30 means the full amount is due 30 days after the invoice date. Therefore, a $5,000 invoice dated June 1 is due July 1.

Under accrual accounting and GAAP, a business records AP when it receives the goods or services, not when it pays.

In addition, this follows the matching principle, which places the expense in the period it helps earn revenue.

What Increases and Decreases Accounts Payable?

Several events change the AP balance. For example, credit purchases raise it, while payments and credits lower it.

• Increases: supplier invoices recorded for inventory, supplies, and services bought on credit.
• Decreases: payments to suppliers, vendor credit memos, returns, and early payment discounts.
• Adjustments: corrections for duplicate invoices, pricing errors, and invoices booked to the wrong period.

As a result, a rising AP balance usually follows higher purchasing. However, it can also signal slower payment.

Accounts Payable vs Accounts Receivable: The Key Difference

Accounts payable differs from accounts receivable. Specifically, AP is money the business owes. In contrast, accounts receivable (AR) is money customers owe the business.

Together, they form the two sides of the working capital cycle.

Accounts Payable vs Accrued Expenses vs Notes Payable

AP is easy to confuse with other current liabilities. Therefore, the table separates the three most common ones.

Payroll liabilities, such as unpaid wages and payroll taxes, belong with accrued expenses, not AP. Moreover, loan principal sits in notes payable.

Accounts Payable Examples

Accounts payable examples include any purchase on credit that a supplier has invoiced. Specifically, the table shows common cases and the entry that records each one.

Every example follows the same rule. Therefore, the expense or asset account takes the debit, and AP takes the credit.

A Worked Example With an Early Payment Discount

A manufacturer buys $10,000 of materials on terms of 2/10 net 30. Specifically, a 2% discount applies if it pays within 10 days.

Paying early saves $200. Therefore, the discount equals about a 37% annualized return for paying 20 days sooner.

However, early payment only makes sense when that return beats the cost of cash. Instead, pay on the due date.

What Is Not Accounts Payable?

Some obligations look similar but fall outside AP.

• Payroll and payroll taxes: recorded as accrued payroll liabilities.
• Loan principal and interest: recorded as notes payable or long-term debt.
• Sales tax and income tax owed: recorded as tax liabilities.
• Customer deposits: recorded as deferred revenue.

Is Accounts Payable a Debit or Credit?

Accounts payable is a credit when it is created and a debit when it is paid.

This follows double-entry bookkeeping. In addition, every transaction has two sides: a debit and a credit.

When a business receives a supplier invoice, it credits accounts payable to increase the liability. Also, it debits the expense or asset account that received the value.

When the business pays the invoice, it debits accounts payable to reduce the liability. It also credits cash to show the outflow.

For other accounts, our debits and credits cheat sheet shows the normal balance of each one.

Accounts Payable Natural Balance

Accounts payable has a natural credit balance because it is a liability account. Does accounts payable have a natural debit balance? No.

A debit balance signals either a prepayment logged before the invoice or a data entry error. Therefore, both need prompt investigation.

Accounts Payable Journal Entry Examples

The key rule is simple. Specifically, when AP increases, a credit was made, and when it decreases, a debit was made.

Is Accounts Payable an Asset or a Liability?

Accounts payable is a current liability, not an asset. In addition, it sits in the current liabilities section of the balance sheet.

Payment falls due within the operating cycle, typically within 30 to 90 days.

Why do some people ask whether AP is an asset? In addition, a higher balance can be useful, because extended payment terms act as supplier financing.

However, the balance itself remains a liability. Instead, the advantage is timing, because the business controls when cash leaves.

Where Does Accounts Payable Go on a Balance Sheet?

Accounts payable appears under current liabilities, usually near the top of that section. In addition, the table shows the full layout.

Where are accounts payable recorded? Within the books, AP sits in the general ledger control account. Meanwhile, the AP subledger holds the invoice-level detail.

Lenders, investors, and auditors review AP aging to confirm the business meets its payment obligations on schedule.

How Accounts Payable Affects Cash Flow and Working Capital

A rise in AP adds to operating cash flow, because the business kept cash it would have spent. Conversely, a fall in AP uses cash.

AP also feeds working capital, which equals current assets minus current liabilities. Therefore, slower payments raise cash but can strain supplier trust.

Finally, DPO joins days sales outstanding and inventory days in the cash conversion cycle.

The Accounts Payable Process: Step by Step

The accounts payable process is the end-to-end workflow that takes an invoice from receipt through payment and reconciliation.

Many teams call it the AP cycle. It sits inside the wider procure-to-pay process, which also covers purchasing.

A structured AP business process protects the company from duplicate payments, unauthorized spend, and vendor fraud. It also produces the accurate liability balances that financial reporting needs.

Step 1: Purchase Order Creation

The AP process ideally begins before the invoice arrives. Specifically, a purchase order (PO) documents the approved purchase: vendor, item, quantity, price, and approver.

Not every purchase needs a PO. However, for significant vendor relationships, a PO before purchase is the first AP internal control.

Invoices without a PO, such as utilities and subscriptions, need a separate approval path.

Step 2: Goods or Services Receipt

When goods arrive or a service is delivered, the receiving team confirms what was actually received against the purchase order.

This confirmation, called the goods receipt, becomes the second document in the three-way match. As a result, it protects against paying for goods never received.

Step 3: Invoice Receipt and Logging

The vendor invoice enters the AP system by email, EDI, or a vendor portal. Next, the AP team logs the invoice date, due date, vendor name, invoice number, and amount.

Every invoice should enter the system on the day it arrives. As a result, unlogged invoices create late payment risk, penalty exposure, and inaccurate AP balances.

Many teams now use OCR or AI invoice capture to read invoice data automatically.

Step 4: Three-Way Matching

Three-way matching compares the purchase order, the goods receipt, and the vendor invoice. Specifically, all three must agree on quantity, price, and description.

If all three match, the invoice moves to approval. However, if they differ, the AP team raises the discrepancy with the vendor or the requester first.

Three-way matching is the single most important control in the accounts payable process. As a result, it prevents payment for goods not ordered, not received, or priced wrongly.

Some teams use a two-way match, which compares only the PO and the invoice, for low-risk spend.

Step 5: Coding and GL Assignment

Each approved invoice is assigned to the correct general ledger account and cost center. For example, office supplies code to an expense account, and equipment codes to a fixed asset account.

Accurate GL coding is essential for financial reporting. In contrast, wrong coding distorts the income statement and misstates balance sheet values.

Step 6: Approval Workflow

Most businesses require one or more approvals before an invoice is scheduled for payment. Also, approval thresholds usually vary by amount.

For example, a junior manager may approve up to $5,000, while the CFO approves anything above $50,000.

Approval workflows prevent unauthorized spend. Moreover, they ensure someone with authority and context signs off before cash leaves the business.

Step 7: Payment Scheduling

Approved invoices are scheduled for payment based on the due date and the business’s cash position. In addition, payment terms such as net 30 or net 60 set when payment is due.

Good AP management pays on the due date, not before. However, an early payment discount makes sense when the return exceeds the cost of paying early.

Step 8: Payment Execution

Payment goes to the vendor by check, ACH transfer, wire, or virtual card. Moreover, the method affects processing time, cost, and the remittance detail the vendor receives.

Dual authorization for payments above a set threshold is a critical control. Therefore, no single employee should both approve an invoice and release the payment.

Step 9: Reconciliation and Period Close

At month end, the AP team reconciles the AP subledger to the general ledger control account. Also, the open invoices should total the AP balance on the trial balance.

Vendor statement reconciliations confirm that the business’s records match the vendor’s records. Therefore, differences need investigation before the period closes.

AP Process for Small Businesses

A small business can run a lighter version of the same cycle. As a result, the five steps below keep control without a large team.

• Log: record every invoice the day it arrives.
• Check: compare the invoice with the order and the delivery.
• Approve: have the owner or a manager sign off.
• Pay: pay by the due date in one weekly payment run.
• Reconcile: match vendor statements and the bank account monthly.

In addition, a weekly payment run reduces mistakes and keeps cash planning simple.

Manual vs Automated AP Workflows

AP automation software captures invoices with OCR, routes approvals, and matches documents automatically. As a result, fewer invoices need manual touches.

However, automation only works on top of clear policies. Therefore, fix the process before you buy the tool.

Accounts Payable Framework and Department Structure

An accounts payable framework ties five parts together: policy, people, process, technology, and reporting. However, when one part is weak, errors surface in the others.

Accounts Payable Department Structure and Roles

Team structure depends on invoice volume. For example, a small business may use one clerk, while a larger company splits the work into specialized roles.

In a small team, one person may cover several roles. However, the person who enters invoices should never approve and release the payment alone.

Accounts Payable Policies and Procedures

Accounts payable procedures are the documented internal controls that govern how invoices are received, verified, approved, and paid.

Without formal procedures, AP becomes a risk source. For example, duplicate payments, fictitious vendors, and unauthorized purchases all exploit gaps in AP controls.

Policies state the rules, while procedures describe how staff follow them. In addition, a standard operating procedure (SOP) lists each step, owner, and control.

Essential AP Internal Controls

• Segregation of duties: the person who enters invoices should not approve them or authorize payment. Combining these roles creates the conditions for fraud.
• Vendor master file control: adding a vendor or changing bank details needs separate approval from a manager outside daily AP. Unauthorized bank changes are a common fraud route.
• Duplicate invoice detection: the system should flag invoices with the same vendor, number, and amount. Once made, duplicate payments are hard to recover.
• Payment authorization thresholds: set dollar limits for each approval level. Payments above the top limit need dual authorization.
• Bank reconciliation independence: the person who processes payments should not reconcile the bank account. An independent reconciler catches unauthorized payments.
• Regular AP aging review: management should review the aging report monthly. Invoices left unpaid risk late fees, credit holds, and strained vendor relationships.

AP Policy Checklist for Small Businesses

A short written policy beats an unwritten habit. Therefore, cover these points at minimum.

• Scope: which purchases need a PO and which do not.
• Approvals: who approves each dollar range.
• Payment terms: standard terms and when early payment is allowed.
• Vendor onboarding: W-9 collection, bank detail verification, and duplicate checks.
• Matching rules: two-way or three-way match and the tolerance for price differences.
• Payment runs: the weekly or biweekly schedule and the release authority.
• Records: how long to keep invoices, approvals, and payment proof.
• Fraud reporting: who staff contact about suspicious invoices or bank change requests.

1099 and W-9 Rules for AP Teams

AP teams also support vendor tax reporting. Therefore, collect a Form W-9 from each vendor before the first payment.

For payments made after 2025, the 1099-NEC and most 1099-MISC thresholds rose from $600 to $2,000 per payee yearly.

However, collect the W-9 anyway, because a vendor under the limit in June may cross it by December. Backup withholding can also apply when a vendor does not provide a taxpayer ID.

The business files Form 1099-NEC by January 31 for the prior year.

Accounts Payable Metrics: Turnover, DPO, and Aging

Accounts payable turnover is a ratio that shows how many times a business pays off its AP balance in a period.

A higher turnover means the business pays suppliers quickly. In contrast, a lower ratio means it takes longer.

Neither is inherently better. Instead, the right level depends on payment terms, cash position, and supplier relationships.

Accounts Payable Turnover Formula

Accounts Payable Turnover = Total Supplier Purchases / Average Accounts Payable

Average Accounts Payable = (Beginning AP + Ending AP) / 2

Many teams use cost of goods sold in place of purchases when purchase data is unavailable. Therefore, state which method you use.

For example, $1.2 million in annual purchases with an average AP balance of $100,000 gives a turnover of 12. As a result, the business pays its supplier balance about every 30 days.

Days Payable Outstanding (DPO)

DPO converts the turnover ratio into days. As a result, it shows the average time the business takes to pay suppliers.

DPO = 365 / Accounts Payable Turnover

A DPO of 30 means suppliers are paid in 30 days on average. Meanwhile, a rising DPO may reflect deliberate working capital management.

However, a sudden rise may signal cash flow distress, and the cash flow statement clarifies which.

Accounts Payable Aging Report

The AP aging report lists every open invoice by how long it has been outstanding. Therefore, management should review it monthly.

As a result, aging analysis is the simplest way to spot problems before suppliers complain.

How to Forecast and Budget Accounts Payable

An AP forecast starts with known commitments. Specifically, open purchase orders, approved invoices, and payment terms show when cash will leave.

Next, add expected purchases for seasonal peaks and new projects. As a result, the AP budget feeds directly into the cash flow forecast.

Finally, compare the forecast with actual payments each month and adjust assumptions.

Accounts Payable KPIs and Cost per Invoice

Four KPIs show whether the AP function is healthy.

• Cost per invoice: total AP cost divided by invoices processed.
• Invoice cycle time: days from receipt to payment approval.
• Exception rate: share of invoices that fail the match or need rework.
• Early payment capture: discounts taken as a share of discounts offered.

APQC data, reported by CFO.com, put the median cost per invoice at $4.58 in consumer products and $9.43 in government.

Published summaries of APQC data also put top performers near $2 per invoice and bottom performers above $10.

For example, processing 6,000 invoices a year at $10 each costs $60,000. In contrast, at $3 each, the cost falls to $18,000.

That is a $42,000 annual difference.

Why Accounts Payable Management Matters for Growing Businesses

As a business grows, the volume, complexity, and risk in accounts payable grow with it.

A small business paying 20 invoices a month can manage AP by hand. However, a growing business paying 200 invoices across 50 vendors, several currencies, and multiple cost centers cannot.

The cost of poor AP management compounds quickly. For example, duplicate payments are hard to recover, and late payments trigger credit holds.

Moreover, mismanaged AP balances produce inaccurate financial statements, which lead to poor management decisions.

Signs Your AP Process Has Outgrown Its Current Setup

• Late payments despite available cash: usually a bottleneck in approval or invoice logging.
• Duplicate payments found after the fact: a sign of weak duplicate detection and poor invoice tracking.
• Invoices older than 90 days in the aging report: unresolved disputes or invoices that were never approved.
• Month-end close delayed by AP reconciliation: the subledger does not match the general ledger.
• Frequent vendor calls about unpaid invoices: suppliers should not need to chase payment.
• No daily view of what is owed: real-time AP reporting should not wait for month end.

Accounts Payable Best Practices

Strong AP teams share a short list of habits. Therefore, use these best practices to tighten your process.

• Require POs for significant purchases: this creates an approval record before spend happens.
• Match before you pay: use two-way or three-way matching on every eligible invoice.
• Pay on the due date: take early discounts only when the return beats the cost of cash.
• Batch payments: weekly payment runs reduce errors and simplify cash planning.
• Verify bank changes by phone: call a known vendor contact, not the number in the request.
• Reconcile vendor statements monthly: catch differences before they become disputes.
• Review aging monthly: management should see every overdue and disputed item.
• Automate repeat work: use OCR, approval routing, and duplicate detection where volume justifies it.
• Document procedures: write the SOP so new staff follow the same steps.
• Separate payroll liabilities: track payroll taxes and wages through accrued payroll, not AP.

Common Accounts Payable Mistakes and Fraud Risks

These errors create financial risk, cash flow disruption, and audit findings in businesses of all sizes.

• No PO for significant purchases: without a PO, there is no approval record before the purchase and nothing to match.
• One person controls the whole cycle: a single employee who enters, approves, and pays invoices can hide fraud. This is the most common control failure in small businesses.
• Paying from statements instead of invoices: statements summarize balances but do not authorize payment. Therefore, paying from them bypasses the three-way match.
• Unverified vendor bank changes: a change request should trigger a call to a known vendor contact.
• Aging never reviewed by management: old items pile up and the AP balance becomes unreliable.
• No monthly vendor statement reconciliation: differences grow into disputed liabilities or missed payments.

Common Accounts Payable Fraud Schemes

Fraud usually exploits weak controls. Therefore, watch for these common schemes.

• Fictitious vendors: fake suppliers set up to receive payments.
• Duplicate or inflated invoices: the same bill submitted twice, or at a higher price.
• Business email compromise: a fraudster poses as a vendor and asks to change bank details.
• Kickbacks: an employee approves inflated invoices in exchange for payment from the vendor.

Segregation of duties, vendor verification, and dual authorization reduce the risk of these schemes.

Frequently Asked Questions: Accounts Payable

What is accounts payable?

Accounts payable is the amount a business owes suppliers and vendors for goods or services received but not yet paid.

It records as a current liability on the balance sheet. Also, when a business buys on credit, AP increases, and when it pays, AP decreases.

What are accounts payable in accounting?

In accounting, accounts payable are the outstanding obligations a business has to creditors for purchases made on credit terms.

Accounts payable follows double-entry bookkeeping. Also, the team credits AP when recording an invoice, then debits AP when making the payment.

What does AP mean in business?

AP stands for accounts payable, which means the money a business owes suppliers, plus the process and team that pay them.

People use AP for the balance, the workflow, and the department.

What are examples of accounts payable?

Examples include inventory, freight, utilities, professional fees, software subscriptions, and contractor invoices bought on credit.

Each one is recorded as a credit to AP until the business pays the supplier.

Is accounts payable a debit or credit?

Accounts payable is a credit when an invoice is recorded and a debit when the invoice is paid.

AP carries a natural credit balance because it is a liability account. However, a debit balance is unusual and signals a prepayment or a data entry error.

What is the normal balance of accounts payable?

The normal balance of accounts payable is a credit.

Crediting AP increases the balance, while debiting it decreases the balance.

Is accounts payable an asset or a liability?

Accounts payable is a current liability, not an asset.

It sits in the current liabilities section because payment falls due within the operating cycle. Also, a higher balance extends supplier financing, yet it remains a liability.

Where does accounts payable go on a balance sheet?

Accounts payable goes under current liabilities on the balance sheet.

The general ledger control account holds the total. Meanwhile, the AP subledger holds the invoice detail.

What is the difference between accounts payable and accounts receivable?

AP is money a business owes suppliers, while accounts receivable is money customers owe the business.

On the balance sheet, AP is a current liability and AR is a current asset.

What is the difference between accounts payable and accrued expenses?

Accounts payable are invoiced obligations, while accrued expenses are costs incurred but not yet invoiced.

For example, an unpaid supplier invoice is AP, and wages earned but unpaid are accrued expenses.

What increases accounts payable?

Credit purchases from suppliers increase accounts payable, and payments or vendor credits decrease it.

An invoice recorded for inventory or services adds a credit to the AP balance.

What is the accounts payable process?

The accounts payable process covers purchase order creation, goods receipt, invoice logging, three-way matching, GL coding, approval, payment, and month-end reconciliation.

Each step includes controls that prevent errors and unauthorized payments. Specifically, three-way matching, segregation of duties, dual authorization, and independent bank reconciliation matter most.

What are accounts payable procedures?

Accounts payable procedures are the documented policies and controls that govern how the AP function operates.

They state who approves invoices, which thresholds need extra authorization, how vendor bank changes are verified, and how aging is reviewed.

What is an accounts payable framework?

An AP framework combines policy, people, process, technology, and reporting into one controlled system.

Each part supports the others, so a gap in one weakens the whole function.

What is accounts payable turnover?

Accounts payable turnover is a ratio that measures how many times a business pays off its AP balance in a year.

Divide total supplier purchases by average accounts payable. Also, DPO equals 365 divided by the turnover ratio.

What is a good days payable outstanding?

A good DPO keeps suppliers satisfied while preserving cash.

It varies by industry and supplier terms, so compare your DPO with your own terms and peers.

How do you forecast accounts payable?

Start with open purchase orders, approved invoices, and payment terms, then add expected seasonal purchases.

Compare the forecast with actual payments each month and adjust.

Is payroll part of accounts payable?

No. Instead, payroll and payroll taxes are accrued payroll liabilities, not accounts payable.

Supplier invoices are AP, while wages and withheld taxes follow payroll accounting.

Who is responsible for accounts payable in a small business?

The owner, a bookkeeper, or a controller usually handles AP in a small business.

However, the person who enters invoices should not also approve and release payments.

How do accounts payable services help a growing business?

Professional accounts payable services give a growing business a structured, controlled AP function without building a full in-house team.

The service covers invoice processing, three-way matching, GL coding, approvals, vendor management, payment execution, and reconciliation.

At 50 or more invoices a month, manual AP often produces duplicate payments, late fees, and reporting errors. As a result, a professional AP function reduces all three.

Final Thoughts

Accounts payable is not back-office administration. Instead, it is a financial function that affects cash flow, vendor relationships, reporting accuracy, and business reputation.

A growing business that runs AP without structure pays for it in duplicate payments, strained vendor relationships, and late fees. Its financial statements also stop reflecting what it owes.

At Expertise Accelerated, our CPA-led accounting teams provide accounts payable services for growing businesses. Specifically, we cover invoice processing, three-way matching, vendor management, payment execution, and month-end reconciliation.
