Accounts payable journal entry: Guide and examples

Accounts payable journal entries show what you owe vendors and help you keep liabilities accurate as your business buys goods and services on credit. Clear entries improve cash planning, reduce surprises at month-end, and ensure vendors are paid on time. When each invoice and payment is recorded correctly, your general ledger captures the full lifecycle of every purchase.

What is an accounts payable journal entry?

An accounts payable journal entry records the amount you owe a vendor when you buy goods or services on credit. It captures the liability created by an invoice and reflects how that obligation moves through your general ledger. Each entry shows which accounts increased or decreased, along with the date and amount, so you have a clear record of what needs to be paid.

AP journal entry: Key components

A clear accounts payable journal entry makes your books easier to audit, reconcile, and understand. These five components help ensure each entry is complete and accurate.

1. Date of transaction: Use the invoice date to show when the obligation occurred. Accurate dates support accrual accounting and ensure expenses fall in the correct reporting period.
2. Account names (debit and credit accounts): Every AP entry requires a corresponding debit and credit. Clear account selection maintains a clean audit trail and prevents misclassified spend.
3. Description of the transaction: A short explanation clarifies what was purchased and why, helping anyone reviewing the books quickly understand the entry
4. Invoice number and vendor details: These details link the entry to supporting documents and make reconciliation faster by tying each entry to the right supplier
5. Amount owed: Enter the full invoice amount, including taxes, fees, and other applicable charges. Recording the correct total prevents discrepancies and improves cash-flow planning.

How to record accounts payable journal entries

Recording an AP journal entry follows a standard double-entry format. A double-entry has two parts: a debit to an expense or asset account and a credit to AP. You’ll follow this format when the invoice arrives, and then reverse it (with a payment entry) when you pay the vendor.

While the steps for recording AP journal entries may seem simple, accuracy is key. Take these two essential steps to ensure clean, traceable records.

Step 1: Record the initial purchase entry

Record the AP entry as soon as you receive an invoice, not when you issue a purchase order or send payment. This entry shows the cost you incurred and the liability you now owe. You’ll debit an expense account such as Supplies Expense or an asset account such as Inventory, and credit Accounts Payable for the full invoice amount.

Example:

You receive a $1,000 invoice for inventory.

• Debit: Inventory $1,000
• Credit: Accounts Payable $1,000

This entry increases both assets and liabilities.

Step 2: Record the payment entry

When you pay the vendor, you create a separate entry to eliminate the liability. You’ll debit Accounts Payable to reduce what you owe and credit Cash or Bank to show the payment amount.

Example:

You pay the $1,000 invoice.

• Debit: Accounts Payable $1,000
• Credit: Cash $1,000

This entry zeroes out the original AP balance.

7 common AP journal entry examples

Accounts payable transactions show up across your business’s purchasing activity. These examples illustrate how typical entries work, using real numbers to make the mechanics clear.

1. Purchase of inventory on credit

When you buy inventory on credit, you record the cost of goods and the amount owed. Suppose you submit a purchase order on August 15 and receive Invoice #15 the same day.

• Debit: Tools Expense $1,500
• Credit: Accounts Payable $1,500

This entry increases assets and records the liability.

2. Office supplies purchase

Office supplies are typically recorded as an expense rather than an asset.

• Debit: Office Supplies Expense $250
• Credit: Accounts Payable $250

3. Service provider invoice

For services such as consulting or maintenance, the entry works the same way.

• Debit: Professional Services Expense $2,000
• Credit: Accounts Payable $2,000

4. Purchase returns and adjustments

Suppose you receive Invoice #10 for $1,000, but the supplier later adjusts it to $800.

• Debit: Tools Expense $200
• Credit: Accounts Payable $200

This reduces the amount owed and adjusts the cost.

5. Paying an invoice

You’re on net 60 terms and pay 45 days after receiving Invoice #15.

• Debit: Accounts Payable $1,500
• Credit: Cash $1,500

6. Paying an invoice late

If you pay Invoice #15 thirty days late, and the supplier charges a $10 late fee plus 1% interest every 10 days, you would owe $1,555.

• Debit: Accounts Payable $1,500
• Debit: Interest Expense $45
• Debit: Late Fee $10
• Credit: Cash $1,555

7. Voiding an invoice

If a supplier cancels an order after invoicing you, you reverse the original entry.

• Debit: Accounts Payable $1,500
• Credit: Tools Expense $1,500

Journal entries and accounts payable workflow

The accounts payable process runs from the moment you decide to buy something to the moment the vendor gets paid. A clear workflow ensures invoices are matched, approved, recorded, and paid in a timely way.

1. Make a purchase order: Issue a purchase order to your vendor after you receive approval
2. Receive the invoice: When the invoice arrives, your AP team performs the 3-way match by comparing the PO, receiving report, and invoice
3. Process the invoice: Approved invoices move through your company’s workflow based on roles and spend limits
4. Post a journal entry: After the match is complete and the invoice is approved, record the accounts payable journal entry
5. Execute payment: When the invoice due date approaches (Net 30, Net 45, or other terms), AP schedules and issues payment
6. Clear payment: Record a second journal entry debiting AP and crediting Cash or Bank to close the liability

Approval workflows

Strong approval workflows keep your journal entries accurate, enforce budget discipline, and ensure only authorized spend hits your books. Clear, structured review paths help prevent miscodings, delays, and unnecessary back-and-forth, and they determine how quickly entries are posted. Documented approvals also strengthen audit readiness by showing who reviewed, coded, and approved each invoice.

To ensure compliant-friendly approval documentation, implement these best practices:

• Maintain a clear record of each approver’s action: Capture timestamps, names, and approval status changes to show who signed off
• Store backup files with the corresponding journal entry: Attach the invoice, PO, receiving report, and approval history in a centralized purchasing system to keep documentation accessible
• Implement version control for modified invoices: Update invoices to reflect changes such as pricing adjustments or discounts, and keep prior versions on file to support reconciliation and audits

Accounts payable (AP) vs. accounts receivable (AR)

Accounts payable (AP) and accounts receivable (AR) sit on opposite sides of the balance sheet. AP tracks what you owe vendors, while AR tracks what customers owe your business. Mixing them up can lead to misstatements and messy books.

Journal entry differences

Accounts payable and accounts receivable journal entries move in opposite directions. AP increases liabilities, while AR increases assets. The structure follows the same double-entry rules, but with mirrored impacts.

For example, if you receive a $2,000 vendor invoice, you’ll debit an expense or asset and credit AP. If you issue a $2,000 customer invoice, you’ll debit AR and credit Revenue. The amounts may match, but the direction and financial statement impact differ.

Best practices for writing AP journal entries

Strong AP processes keep your books accurate, your payments timely, and your vendors satisfied. These best practices help you stay ahead of issues and avoid costly errors.

Importance of timely recording

Timely data entry ensures your financial statements reflect real obligations. Waiting to enter invoices can understate liabilities and overstate cash, making decisions harder. Recording invoices as soon as they arrive also reduces duplicate payments and supports predictable vendor relationships.

Regular reconciliation procedures

Payment reconciliation confirms that your accounting system matches vendor statements, bank activity, and internal records. Reconciling weekly or monthly helps you catch discrepancies early and identify coding errors or missed invoices. It also builds trust in your financial data and supports better budgeting and forecasting.

Internal controls and segregation of duties

Strong internal controls reduce the risk of fraud, errors, and unauthorized payments. Segregating duties ensures no single person controls the entire AP process and keeps oversight intact.

Common controls include:

• Invoice approval rules: Threshold-based approvals ensure the right people authorize spend
• Vendor management policies: Structured onboarding helps prevent fraudulent vendor creation and keeps vendor data clean
• Restricted payment access: Limiting who can send or approve payments protects cash and strengthens audit trails

Documentation requirements

Good documentation supports clean audit trails, faster close cycles, and fewer vendor disputes. Every journal entry should link to invoices, receipts, and approvals so reviewers can see how amounts were calculated. Complete documentation also makes training easier by giving new team members clear examples to follow.

Common mistakes to avoid

Even small errors can lead to messy books and compliance issues. Watch for these common pitfalls:

• Recording entries late
• Misclassifying expenses
• Skipping 3-way match
• Forgetting to clear AP after payment
• Using inconsistent vendor names
• Missing approval documentation
