What Is Accounts Payable Accrual?

An accounts payable accrual records an expense and obligation in the period when goods or services were received, even though the vendor invoice has not yet entered the payables system.

The purpose is period cutoff. Without the accrual, the current period may omit a real cost and the next period may include too much expense when the invoice finally arrives. The entry should be based on evidence, a reasonable estimate, and a process that prevents the later invoice from creating a duplicate expense.

Accounts payable versus accrued expenses

Accounts payable usually contains vendor invoices that have been received, entered, and remain unpaid. An accrued expense represents an obligation that belongs to the period but is not yet recorded through the normal vendor-bill process.

Question	Accounts payable	Accrued expense
Has the invoice usually been received?	Yes	No, or it is not ready for normal processing
Is there vendor-level detail?	Usually yes	Often supported by a separate accrual schedule
What supports the amount?	Vendor invoice and approval evidence	Receipt, contract, time record, estimate, or subsequent invoice
How is it cleared?	Payment applied to the bill	Reversal or release when the actual invoice is recorded

Both are liabilities under accrual accounting when the business owes for goods or services already received. They differ mainly in the stage of documentation and processing.

When an AP accrual may be needed

An accrual may be appropriate when the reporting period has ended and the business has received value but not the related invoice. Common examples include:

• Contractor or subcontractor work completed before month-end.
• Utilities used during the month but billed later.
• Professional services delivered before the provider issues an invoice.
• Goods received near period-end when the invoice is still in transit.
• Payroll-related costs earned in the period but paid afterward.
• Software, rent, or service charges that relate to the period but have not posted.

The accounting treatment depends on the reporting basis and facts. A business using cash-basis records for a particular purpose may not present the same accruals as an accrual-basis financial statement. Keep the basis clear.

Basic journal entry

Assume a contractor completed an illustrative $3,000 of approved work before month-end, but the invoice will arrive next month. The month-end entry may be:

• Debit the appropriate expense or direct cost: $3,000
• Credit accrued expenses or another appropriate liability: $3,000

This records the cost in the period in which the work was received and places the obligation on the balance sheet.

When the next period begins, the accrual may be reversed. If the vendor invoice then arrives for $3,100, the normal bill records $3,100 of expense and accounts payable. The reversal offsets the original $3,000 estimate, leaving a $100 current-period difference. Another workflow can clear the accrual directly against the invoice. What matters is that the process records the actual bill once and removes the estimate once.

How to build a supportable accrual

Identify services and goods received before cutoff

Review purchase orders, receiving records, open projects, service confirmations, unbilled vendor activity, recurring contracts, and invoices received shortly after period-end. Ask operational owners about work completed but not yet billed.

Estimate from the best available evidence

Use an approved rate times completed quantity, contract milestone, time record, receiving document, historical usage adjusted for current facts, or a vendor estimate. Avoid a round-number guess with no calculation.

Record the service period

The schedule should state what was received, the relevant dates, the vendor when known, the account or project, the calculation, and the person who confirmed completion.

Assign a reversal or clearing method

State whether the entry automatically reverses in the next period or will be cleared when the actual invoice is posted. Track every accrual until it is resolved.

Compare the estimate with the actual invoice

When the invoice arrives, compare it with the accrual. A difference may be a normal estimate variance, a change in scope, incorrect cutoff, or missing receipt information. Record the explanation when it matters to the close.

Example accrual schedule

Vendor or source	Service received	Basis	Accrued amount	Expected invoice
Field subcontractor	Installation completed June 29	Approved milestone	$3,000	Early July
Utility provider	June usage	Usage estimate	$780	Mid-July
Legal provider	June work through June 30	Hours confirmed by provider	$1,250	July

All amounts are illustrative. A real schedule should link to the supporting document and show how each item was reversed or cleared.

Cutoff mistakes to avoid

Accruing based only on invoice date

The invoice date may not identify when the business received the goods or services. Review the delivery, completion, or service period.

Leaving both the accrual and the invoice in expense

If the estimate is not reversed or cleared, the same cost can be recorded twice. Reconcile the accrual schedule to the liability account and inspect subsequent invoices.

Reversing an accrual without recording the actual bill

An automatic reversal removes the liability at the beginning of the next period. If the invoice never arrives or is never entered, the obligation disappears from the books even though it may remain unpaid. Review open reversals.

Using an unsupported plug

An accrual should represent identified activity. A broad entry designed only to reach a preferred profit number is not a substitute for a cutoff process.

Keeping stale accruals indefinitely

An old accrual may signal a missing invoice, cancelled obligation, duplicate, disputed amount, or failure to clear the estimate. Age the schedule and assign an owner to each unresolved item.

Month-end AP accrual checklist

• Reconcile the accounts payable aging to the general ledger.
• Review invoices received after month-end for earlier service periods.
• Ask purchasing and operations about unbilled goods or completed work.
• Review recurring vendors missing from the month’s activity.
• Document the calculation and evidence for each accrual.
• Approve and post the entry with a defined reversal or clearing method.
• Reconcile the accrued-liability account to the schedule.
• Compare prior accruals with actual invoices and resolve differences.

The process connects the month-end close, the vendor workflow, and the payable reconciliation. The result should be an expense recorded in the right period and a liability that can be traced to real activity.
