Accounts payable journal entry explained: Definition, types and examples

Your company’s accounts payable ledger keeps track of your credit purchases. But do you know how to correctly read the ledger and add new entries? Here, we’ll walk you through it.

Published July 2, 202612 min read Share

Your accounts payable (AP) ledger is where your business records what it owes to suppliers for goods and services purchased on credit.  

Knowing how to read that ledger, and how to record new entries correctly, keeps your books accurate and your payment obligations clear. 

As your business grows and you take on more suppliers, AP journal entries become a routine part of bookkeeping.  

This guide explains what AP journal entries are, when you need them, and how to record a journal entry for accounts payable correctly, with examples. 

Key takeaways

• Accounts payable (AP) journal entries record money owed to suppliers using double-entry bookkeeping, helping keep liabilities, financial statements, and payment records accurate and balanced.
• Record AP journal entries whenever supplier balances change, including invoices, payments, returns, discounts, credit memos, and late fees. Always correct previous errors with separate entries.
• Accurate AP journal entries support reliable financial reporting, while common errors can be reduced through timely recording, thorough reviews, clear documentation, and internal controls.
• AP automation software streamlines journal entries by reducing manual work, improving accuracy, managing approvals, and providing real-time visibility into invoices, payments, and audit trails.

Here’s what we’ll cover:

What is an accounts payable journal entry?

An AP journal entry is a formal accounting record of money your business owes a supplier. These entries track increases in what you owe (new invoices) and decreases in pending obligations (payments made). 

Like all journal entries, an accounts payable entry follows double-entry bookkeeping: every transaction touches at least two accounts so the books stay balanced. 

When you receive an invoice, you typically debit an expense or asset account and credit accounts payable.  

When you pay that invoice, you debit accounts payable and credit cash or your bank account.  

Maintaining these entries accurately is essential to producing financial statements that reflect your business’s true obligations.

Where this fits within the broader AP process

Journal entries don’t happen in isolation—they’re one step in a wider accounts payable workflow.  

Most businesses follow a similar cycle: 

• Invoice receipt: your business receives an invoice from a supplier for goods or services provided on credit. 

• Review and approval: the invoice is checked against purchase orders, contracts, or delivery confirmations to confirm accuracy. 

• Recording the transaction: once approved, the entry is recorded, typically debiting an expense or asset account and crediting accounts payable. 

• Payment scheduling: the invoice is scheduled for payment based on agreed terms, available cash flow, or early-payment discounts. 

• Payment and reconciliation: when paid, a new entry reduces accounts payable and credits cash, and the invoice is marked settled. 

Together, these steps keep your liabilities accurate, prevent duplicate payments, and keep your financial statements current. 

How AP journal entries affect your financial statements

Every accounts payable journal entry flows beyond the ledger and into your financial statements.

Recording entries accurately ensures your reports reflect the true state of your business’s obligations and performance.

Balance sheet 

Accounts payable sits on the balance sheet as a current liability. Recording a new accounts payable journal entry increases total liabilities; paying it down reduces them. 

Income statement 

The debit side of an accounts payable journal entry usually represents an expense (utilities, consulting fees, inventory costs, and so on), which affects net income for the period.  

Timing and accuracy here directly affect how profitability is reported.

Cash flow statement 

When an invoice is paid, the resulting decrease in accounts payable shows up as an operating cash outflow, linking your AP process to working capital and day-to-day liquidity. 

When do you need an accounts payable journal entry?

You’ll need to record an AP entry whenever a transaction changes what your business owes a supplier.  

Common triggers include: 

• Receiving an invoice for goods or services purchased on credit. 

• Returning damaged or incorrect goods to a supplier. 

• Making a payment toward an outstanding invoice. 

• Receiving a credit memo from a supplier. 

• Adjusting an invoice to reflect a discount. 

• Incurring late fees or interest charges on an overdue invoice. 

Even correcting a mistake in a previous entry requires a new journal entry of its own—never edit the original. 

Accounts payable and receivable journal entries

Just as accounts payable tracks what you owe, accounts receivable (AR) tracks what customers owe you.  

The AP and AR ledgers mirror each other, but the debit and credit logic is reversed. 

• Accounts payable: a liability; records money owed to suppliers; increases with credits, decreases with debits. 

• Accounts receivable: an asset; records money owed by customers; increases with debits, decreases with credits. 

AP journal entries versus accrued payables and notes payable

Accounts payable entries typically arise from short-term purchases on credit, documented by invoices.

However, in business, there are often circumstances in which you have other pending payments subject to slightly different terms.

For example, you may wish to plan ahead by recording expenses incurred but not yet invoiced, such as utilities or employee wages. These are called accrued payables.

Or your supplier may accept a formal promise to pay under specific terms, known as promissory notes.

Some businesses prefer this option when dealing with larger transactions or when a more formal payment agreement is required, often including interest charges and defined repayment schedules.

You record promissory notes in another ledger, called notes payable.

These transaction types, along with accounts payable (AP), represent liabilities and obey the same double-entry accounting principles.

The difference is that:

• Accounts payable entries are used for standard supplier transactions.
• Accrued payable entries are for estimated expenses.
• Notes payable entries are for formal debt agreements.

While AP credit transactions can be balanced by a debit entry in an expense ledger, asset account, or within the AP ledger itself (when making a payment), it’s slightly different for the other two liability accounts.

Balancing accrued payable and notes payable accounts has specific requirements:

• Accrued payables: typically balanced by a debit entry to the related expense account.
• Notes payable: balanced by a debit entry to either the cash account (when the loan is received) or, during repayment, by debit entries to both the cash account and an interest expense account.

What if an accounts payable journal entry is incorrectly recorded?

If you discover an incorrect AP journal entry, it must be corrected immediately. Don’t delete it as doing so will break the audit trail. Instead, record a separate correcting entry.

If the original entry overstated liabilities, you’ll add a correcting debit to the AP and a corresponding credit to the affected account.

If the original entry understated liabilities, you credit the AP and add a corresponding debit to the affected account.

Clear documentation of the correction is essential. For example, the correcting entry should reference the original incorrect entry and explain the reason for the adjustment, maintaining a transparent and auditable record.

It goes without saying that incorrect entries in any ledger account have a knock-on effect all the way down to your financial statements.

This would affect your key metrics and your business’s ability to make informed decisions about resource allocation, investment, and operational efficiency.

Key elements of an accounts payable journal entry

For accuracy and ease of audit, every AP journal entry should include: 

• The date of the transaction. 

• The accounts affected, typically accounts payable plus an expense or asset account. 

• Matching debit and credit amounts. 

• A clear description of the transaction. 

• The supplier’s name and/or invoice number for reference.

Accounts payable journal entry examples

The above examples deal with the overall circumstances of typical AP journal entries. But what do they look like in practice?

Here are some detailed examples:

Making a purchase

Suppose your business buys $2,000 of office supplies on credit from a supplier. You’d debit office supplies $2,000 and credit accounts payable $2,000.  

Using a specific account like office supplies, rather than a generic expense account, gives you more detailed and useful spending data. 

Date	Description	Supplier	Account	Debit	Credit
2026-07-03	Paper and toner (Inv. #03494)	Northern Office Supplies Ltd.	Office supplies	$2,000
			Accounts payable		$2,000

Paying off the purchase

A month later, when the invoice is paid, accounts payable is debited $2,000 and cash is credited $2,000, since the liability is now settled.

Date	Description	Supplier	Account	Debit	Credit
2026-08-03	Paper and toner (Inv. #03494)	Northern Office Supplies Ltd.	Accounts payable	$2,000
			Cash		$2,000

Returning part of a purchase

If some supplies turn out to be damaged or unneeded, you might return $500 worth two days after the original invoice.  

You’d debit accounts payable $500 and credit office supplies $500, reducing both the liability and the recorded cost.  

This adjustment uses a new credit memo number—never reuse the original invoice number.

Date	Description	Supplier	Account	Debit	Credit
2026-07-05	Paper and toner — Credit memo #1	Northern Office Supplies Ltd.	Accounts payable	$500
			Office supplies		$500

Voiding or reversing an entry 

If an order is cancelled entirely after the invoice has already been recorded, the original entry should be reversed rather than deleted.  

Suppose a $3,000 equipment purchase on credit is cancelled before delivery: 

Date	Description	Supplier	Account	Debit	Credit
2026-12-05	Equipment order cancelled — Inv. #7782 reversed	TecSource Canada Inc.	Accounts payable	$3,000
			Equipment (asset)		$3,000

In this accounts payable journal entry example: 

• Accounts payable is debited to remove the liability. 

• The equipment asset account is credited to eliminate the originally recorded asset. 

• The reversal restores both accounts to their pre-transaction balances. 

Recording the adjustment as a separate journal entry preserves a complete audit trail.

Anyone reviewing the ledger can clearly see the original transaction and the reversal, maintaining transparency and compliance.

Recording late fees and interest charges 

If an invoice is paid late, a supplier may add a late fee, interest charge, or both.  

Suppose a supplier applies a $150 late fee and $50 in interest, for $200 in total additional liability: 

Account	Debit	Credit
Late fee expense	$150
Interest expense	$50
Accounts payable		$200
Total	$200	$200

Both expense accounts are debited to reflect the added cost, and accounts payable is credited for the full $200 increase in liability, keeping total debits and credits in balance.  

When the supplier is eventually paid, a separate entry reduces accounts payable and credits cash for the full amount due. 

Common AP journal entry errors and best practices

Even with digital systems there is always a human element, such as data entry. This means there is the possibility for errors and anomalies to occur.

Here are some common errors to look out for:

• Incorrect account selection: for example, a purchase of equipment might be incorrectly recorded as an office supply expense. This often happens due to a lack of understanding of the chart of accounts or carelessness during data entry.
• Wrong debit or credit amounts: sometimes we simply hit the wrong key, creating a typo, or we miscalculate. And in the rush to get things done, it’s easy to misread the figure on the invoice. Either way, incorrect figures will eventually lead to an imbalance in the accounting equation.
• Other data entry errors: common offenders include wrong invoice numbers or dates. Duplicate entries can also happen when the same invoice is recorded multiple times, leading to inflated liabilities.
• Missing documentation: this refers to the absence of supporting documents such as invoices, purchase orders, or credit memos. Often, it’s a matter of forgetting to attach the document in an email, or link to it in your accounting system. Without these, it’s difficult to verify the accuracy of journal entries and maintain an audit trail.
• Late entry of transactions: failing to record transactions promptly can lead to inaccurate financial statements and cash flow issues. Delays can cause missed payments, late fees, and strained supplier relationships.
• Overlooking unexpected operational events: you may have to adjust figures to account for returns (such as when goods are sent back to the supplier), discounts (for early payment or bulk purchases, for example), or credit memos sent in such cases. Failure to account for such changes can result in overstated liabilities and incorrect financial reporting.

To avoid these errors, ensure proper training for accounting staff, implement a review process, and maintain clear documentation.

Always double-check entries before posting them. Do this by:

• Cross-referencing amounts: compare the journal entry amounts to the supporting documents.
• Reviewing the description: make sure the description is clear and accurate.

Avoid relying solely on manual data entry, which is prone to errors. But even with an automated system, you should implement protocols for checks and balances.

For example, have a second person review all journal entries before they’re posted to the general ledger.

Or implement a segregation of duties, so that the person who enters the data isn’t the same person who approves the payments.

Managing accounts payable journal entries with AP automation software

An effective accounts payable solution automatically generates journal entries from invoices, reading and extracting relevant data such as invoice numbers, monetary amounts and supplier information.

It can also manage approval workflows and thresholds, as well as payment scheduling.

This is possible because you can predefine rules and approval hierarchies, ensuring that invoices are routed to the appropriate personnel for review and authorization.

Integration with your other financial systems gives you a centralized overview of all your AP processes and transactions.

This means you can instantly review bills, approvals, payment status, posting details, and audit trails—anything that you register electronically.

These features help you save time in basic operations by minimizing manual work and through a reduction of errors, such as duplicate invoices. The improved real-time visibility into your AP ledger can also help you detect and prevent fraud.

All in all, automated accounts payable software makes your financial management process more streamlined and efficient.
