Accounts Payable Journal Entry: How to Record Invoices, Payments, and Card Payments

An accounts payable journal entry records money a company owes a supplier. You credit accounts payable when you record the supplier's invoice and debit it when you pay the bill, with the other side going to expense, inventory, or cash.

The entries themselves are simple, and most accounting students learn them in the first month. What makes them hard in practice is volume and timing, with hundreds of invoices keyed by hand, accruals rebuilt from spreadsheets at every month-end, and card or ACH payments that clear on a different day than the books expect. The virtual card entry, in particular, trips up more closes than it should.

Key Takeaways

• Accounts payable is a liability with a normal credit balance. It's credited when an invoice is recorded and debited when the invoice is paid.

• Most AP journal entries are generated by bill and payment transactions in the ERP. Manual journals are the exceptions, such as accruals, reclasses, and corrections.

• A vendor payment made by commercial card takes two entries. AP moves to a card liability on the payment date, and cash leaves only when the card statement is paid.

• Goods received but not invoiced accruals, unreconciled clearing accounts, and miscoded invoices cause most of the AP trouble at month-end close.

• Automation can remove most routine AP entries, but judgment accruals and reclasses will stay manual.

Is accounts payable a debit or a credit?

Accounts payable is a credit. It's a liability account with a normal credit balance, so it increases with a credit when you record a supplier invoice and decreases with a debit when you pay that invoice.

A common mistake is to debit AP when an invoice arrives. OpenStax's Principles of Financial Accounting puts it plainly, noting that accounts payable increases on the credit side and that a payment decreases it on the debit side. Here's the pairing in its simplest form.

What is the double entry for accounts payable?

The double entry for accounts payable pairs the AP credit with a debit to whatever the company bought, and later pairs the AP debit with a credit to cash. Every AP transaction touches two accounts, and the debits always equal the credits.

Take a $5,000 invoice for office furniture that the company expenses. On receipt, debit office expense $5,000 and credit accounts payable $5,000. Thirty days later, when the bill is paid, debit accounts payable $5,000 and credit cash $5,000. The AP balance goes up and comes back down to zero, while the expense stays on the income statement and cash ends up $5,000 lower. If the vocabulary is still settling in, a glossary of AP terms and definitions helps with the labels that vary between systems.

Where do AP journal entries come from in an ERP?

In most ERPs, AP journal entries come from transactions rather than typed journals. Entering a bill posts the debit and credit automatically, and recording a payment posts the reverse. In NetSuite, Sage Intacct, Business Central, or Acumatica, an accountant rarely types "Dr expense, Cr AP" for a routine invoice.

Manual journal entries are the exceptions. They cover accruals for goods received before the invoice, reclasses when an invoice was coded to the wrong account, corrections, and anything the accounts payable process couldn't route through a bill. According to APQC's Open Standards Benchmarking measure for the percentage of journal entries processed manually, the median organization processes 10.0% of its journal entries manually, based on 544 organizations. That share looks small until you remember that the manual 10% is where most close-week errors live.

If your team is still keying invoices as journal entries rather than as bills, fix that first. Count last month's manual AP journals and sort them by type, because that list is usually the clearest map of where your close is losing time.

What journal entries does AP post from invoice to payment?

AP posts five common entries between receiving an invoice and settling it, and round numbers make each one easier to follow.

• Recording an expense invoice

• Recording an inventory invoice

• Paying by check or ACH

• Taking an early-payment discount

• Recording a return or debit memo

Recording an expense invoice is the most common. A $2,400 invoice for IT services posts like this:

Recording an inventory invoice depends on your inventory system. Under a perpetual system, a $10,000 inventory purchase debits inventory directly. Under a periodic system, it debits a purchases account that's closed to inventory at period end.

Paying by check or ACH clears the liability. When the $2,400 IT invoice is paid, debit accounts payable $2,400 and credit cash $2,400. The entry is identical for both rails, though the mix between them has shifted fast. According to the Federal Reserve Bank of Cleveland's September 2026 Payments Research Brief, B2B Payments: A Gradual Shift from Checks to Electronic Payment Methods, checks fell from 32% of B2B payments by number in 2015 to 13% in 2024, while ACH rose from 25% to 41%. Checks persist mostly because suppliers ask for them, with 68% of companies saying they use checks for vendor payments because vendors require them, according to AFP's 2026 Payments Fraud and Control Survey Report: Key Highlights.

Taking an early-payment discount splits the credit. OpenStax's chapter on current liabilities walks through terms of 2/10, n/30. A $10,000 inventory invoice paid within 10 days under a perpetual system posts as follows.

Under a periodic system, the $200 goes to a purchase discounts account instead of inventory. Whether discounts are worth taking at all is a cash question, and the math behind early payment discounts and dynamic discounting usually favors them when cash is available.

Recording a return or debit memo reverses part of the original entry. Returning $1,000 of goods debits accounts payable $1,000 and credits inventory, or the original expense account, for $1,000. It's also the entry that most often goes wrong in practice. Credit memos that sit misaligned with open bills are a familiar complaint from AP teams, and they leave the vendor's balance overstated until someone notices on a statement.

What is a purchase journal entry?

A purchase journal entry records goods or services bought on credit. It debits inventory, purchases, or an expense account and credits accounts payable, and it's the same entry as recording a supplier invoice.

The term has an older meaning, too. In manual bookkeeping, the purchases journal was a special journal listing every credit purchase, with totals posted to the general ledger at month-end. Modern ERPs replaced it with the bill register, though some textbooks still use the old name.

How do you record a partial payment?

Record a partial payment by debiting accounts payable and crediting cash for the amount actually paid. The rest stays open on the vendor's balance until the next payment.

If you pay $4,000 against a $10,000 invoice, debit accounts payable $4,000 and credit cash $4,000. The remaining $6,000 stays on the accounts payable aging report under its original due date. Apply the payment to the specific invoice in the ERP rather than to the vendor account in general, or the aging report will show the wrong invoice as past due.

How do you record a vendor payment made by virtual card?

A vendor payment made by virtual card takes two entries. On the payment date, debit accounts payable and credit a card liability or card clearing account. When you pay the card statement, debit the card liability and credit cash.

The two-step follows from basic double entry. Paying by card swaps one liability for another, so the supplier's invoice is closed on March 5 while the company still owes the card issuer until the statement is paid. Cash leaves on April 10. That gap is why companies pay suppliers by card, and it's also why the entries need care. The supplier is paid on time, AP shows the invoice as closed, and the bank account hasn't moved.

Reconciliation happens at the card liability account. Each month, match the card statement to the cleared AP items it contains, and anything left in the clearing account is either a timing difference or a problem. I've seen a card clearing account carry an unexplained five-figure balance for an entire quarter because AP assumed treasury reconciled it and treasury assumed AP did. Assign an owner to that account before the first card payment goes out. A good virtual card ERP integration posts both sides automatically, which turns this reconciliation into a review instead of a rebuild.

Card rebates need a policy decision, too. Companies commonly book virtual card rebates either as a reduction of expense or as other income, and practice varies. Pick one treatment, document it, and confirm it with your auditors before the first rebate check arrives. Corpay's single-use virtual cards tie each card charge to one invoice, which keeps that clearing account simple to reconcile.

Which AP journal entries cause the most trouble at month-end close?

The AP entries that cause the most trouble at close are the manual ones that depend on timing and judgment. Five come up again and again:

• Goods received but not invoiced (GRNI) accruals, rebuilt from receiving logs and spreadsheets every month

• Unrecorded liabilities, found when an invoice dated before cutoff arrives after the books close

• Reclasses for invoices coded to the wrong expense account or department

• Duplicate or reversed payments that need correcting entries

• Unreconciled clearing accounts for card and ACH payments

Each of those adds days. According to APQC's Open Standards Benchmarking measure for cycle time to complete the monthly financial close, the median organization takes 8.0 days, based on 3,389 organizations. A smaller vendor survey points the same way. Ledge's Month-end close benchmarks for 2025, based on a survey of just 100 finance teams, found that 50% take six or more business days to close. Treat the Ledge figure as directional, given the sample size and the fact that Ledge sells close software.

Duplicate payments deserve a word of their own. Once a duplicate payment clears, you recover it through a vendor credit or a refund, or you offset it against a future invoice. Each choice leaves a different trail for auditors to follow.

How do you record an accrual for goods received but not invoiced?

Record a GRNI accrual by debiting expense or inventory and crediting accrued liabilities, or a dedicated GRNI account, for the value of goods received without an invoice. Reverse the entry when the invoice arrives and is posted to AP.

OpenStax defines an accrued expense as an "expense incurred in a period but not yet recorded, and no money has been paid," and that's exactly what GRNI is. If $15,000 of materials arrived on March 28 and the invoice won't come until April, debit inventory $15,000 and credit GRNI $15,000 on March 31. On April 1, reverse it. When the invoice posts, the normal AP entry takes over. The timing logic behind this is the same one that separates accrual and cash accounting, and getting it wrong understates both expenses and liabilities for the month.

Why do manual journal entries slow down the close?

Manual journal entries slow down the close because each one needs someone to gather support, calculate the amount, post it, and get it reviewed, and every step waits on the person before it. Errors compound the delay, since a wrong accrual found on day five means re-running the reports built on day three.

The error rate isn't trivial. Gartner's February 2024 survey of 497 accountants found that 18% make financial errors at least daily and about a third make several a week, which Gartner tied to capacity constraints. The same survey found that 73% of accountants say new regulations increased their workload over three years. Busy people keying entries by hand make mistakes, and the reviews that catch them are what stretch a close from five days to eight.

How does AP automation reduce manual journal entries?

AP automation reduces manual journal entries by turning invoices and payments into system transactions that post themselves. Captured and coded invoices post as bills, approvals finish before cutoff, and payment status syncs back to the ERP.

An invoice that's captured, matched to a purchase order and receipt through three-way matching, and approved before the period ends posts as a bill and never becomes a GRNI accrual. Payments that sync back let the clearing account reconcile against the payment file, so the AP reconciliation shrinks to an exception review.

Payment volume makes this more pressing each year. According to the Federal Reserve Board's 2025 Federal Reserve Payments Study initial findings, U.S. noncash payments totaled 236.6 billion in 2024, and ACH reached almost three quarters of noncash payment value. Nacha's report on ACH Network volume in 2025 counted about 8.1 billion B2B ACH payments in 2025, up nearly a tenth from the year before. Checks carry the extra cost of fraud, with AFP's 2026 survey finding that checks were the payment method most often hit by fraud, affecting 58% of organizations.

A practical month-end checklist for AP looks like this:

1. Confirm every approved invoice dated in the period has posted as a bill.

2. Run the GRNI report from receiving records and accrue every shipment that arrived before cutoff without a matching invoice.

3. Reconcile the card and ACH clearing accounts against payment files and card statements.

4. Review open debit memos and credit memos against vendor balances.

5. Tie out the AP subledger to the GL.

6. Reconcile your largest vendors' statements, using vendor statement reconciliation to catch missing invoices.

7. Reverse prior-month accruals that have been replaced by posted invoices.

Some of this stays manual no matter what you buy. Judgment accruals for services without receipts, reclasses after a budget owner disputes coding, and corrections for supplier errors all need a person. My view is that the realistic target is fewer manual journals. Zero isn't a sensible goal, and a team that chases it usually ends up automating entries that needed judgment. Corpay's ERP integrations include NetSuite and Sage Intacct, so approved invoices post as bills without re-keying.

Cut manual AP entries with Corpay

The entries that eat the close are the ones nobody's system created, from GRNI rebuilt in a spreadsheet to a card clearing account that no one reconciled. Corpay works alongside your ERP to take those off the AP team's plate.

Corpay AP automation captures invoices and runs fast and accurate 2- and 3-way matching against purchase orders, so approved invoices post to the ERP as bills. It also includes a vendor portal. Corpay's fully managed AP enrolls suppliers and delivers payments by virtual card, ACH, or check, then syncs payment status back for reconciliation, so AP stops keying both sides by hand. Corpay connects through 100+ ERP integrations, including NetSuite, Sage Intacct, Microsoft Dynamics 365 Business Central, and Acumatica. AP teams save about 40% of the time they spend on invoice processing, card payments use single-use virtual cards, and Corpay pays its customers more than $800M in rebates each year. Implementation is often measured in weeks.

Frequently Asked Questions

What is the normal balance of accounts payable?

Accounts payable has a normal credit balance because it's a liability. Recording a supplier invoice increases the balance with a credit, and paying the invoice reduces it with a debit. A debit balance in AP usually means an overpayment, a duplicate payment, or an unapplied credit memo.

What are the five common AP journal entries?

The five common AP journal entries record an expense invoice, record an inventory invoice, pay an invoice by check or ACH, take an early-payment discount, and record a return or debit memo. Accruals and card payments add more entries at month-end.

What is a P2P journal entry?

A P2P, or procure-to-pay, journal entry is any entry generated along the purchasing cycle, from purchase order and receipt through invoice and payment. In practice, it usually means the GRNI accrual, the invoice entry crediting AP, and the payment entry debiting AP.

How do you reverse an AP journal entry?

Post an equal and opposite entry, debiting what was credited and crediting what was debited, dated in the period the correction belongs to. For a bill posted in error, most ERPs let you void the bill, which creates the reversing entry and keeps the audit trail intact.

Is paying a vendor by corporate card recorded differently from paying by ACH?

Yes. An ACH payment debits accounts payable and credits cash on the same day. A card payment debits accounts payable and credits a card liability, and cash moves only when the card statement is paid, so card payments need a second entry and a monthly reconciliation.

Does paying by card change days payable outstanding?

Paying by card closes the supplier invoice on time, so days payable outstanding measured on AP doesn't stretch. What extends is the company's cash timing, because cash leaves when the card statement is paid, often weeks after the supplier was paid.
