The Cost Arrives Before the Invoice

The courier has finished the October deliveries. Customers have their books. Maya has no invoice yet.

The missing document is easy to understand once somebody points it out. The harder question is how the close team discovers it among all the work Stories Inc. has received.

This is the completeness question: what happened that has not reached the books? A ledger can balance perfectly while overlooking an entire obligation.

Find the activity before estimating its cost

The delivery owner confirms which customer deliveries were completed in October. Accounts payable (AP) checks the invoices and credit notes already recorded. The accountant compares those records with the service confirmations, agreed rates and existing accruals. This establishes both what is missing and what must not be counted again.

In our fictional case, completed customer-delivery services support an initial estimate of $2,400. These are outbound services for completed sales, not freight bringing unsold books into the warehouse.

A purchase order alone does not prove that work was performed. Neither does a department's unspent budget establish what it owes. A useful confirmation identifies the service, the period covered, the work completed and the basis for the amount. Open orders, unbilled receipts and invoices arriving after month-end can help the team find items requiring that confirmation.

This search also reaches beyond suppliers. Payroll can identify earned but unpaid wages. A borrowing schedule can identify accrued interest. Different records answer the same question: what obligation exists at the reporting boundary that the ledger has missed?

Give the estimate a record that can be followed

Stories Inc. records $2,400 of delivery expense and a $2,400 accrued liability. Profit before tax falls; cash does not move. That is the function of an expense accrual: bring an incurred cost and its obligation into the appropriate period. OpenStax: Accrued expenses

The journal needs a place in an accrual register—a list that connects each estimate to its evidence and eventual settlement. For this item, the record identifies the supplier and activity, October service period, delivery-list and rate calculation, journal reference, responsible person, and intended clearing or reversal method. When the invoice arrives, its reference completes the link.

That record gives the reviewer a practical test: is this supported October work, is the amount reasonable, and has AP already recorded any of it? It also gives the next month's accountant something more useful than an unexplained opening liability.

Goods received without an invoice can require similar completeness work but a different debit. If the business controls qualifying inventory still on hand, the missing entry may be inventory and a liability, rather than an immediate expense. Finding an omitted obligation does not settle the classification of what was received.

Replace the estimate without adding the cost twice

Before October sign-off, the courier's invoice arrives for $2,700. The delivery owner confirms the service period; Accounts payable (AP) checks the bill against the activity and rates. An additional $300 charge is supported. The accountant links the invoice to the $2,400 accrual already posted.

There is already $2,400 of October expense. Recording another $2,700 expense would charge $5,100 for a $2,700 service. Instead, the entry clears the estimated liability, adds only the difference to expense, and records the supplier payable:

Entry for the confirmed invoice	Debit	Credit
Remove accrued delivery liability	$2,400	—
Add delivery expense difference	$300	—
Record accounts payable	—	$2,700

October now contains $2,700 of delivery expense and a $2,700 payable. The accrual register shows how the estimate was cleared. Paying that invoice later will reduce the payable and cash; it will not create another delivery expense.

An invoice remains evidence to inspect. Duplicated charges, disputed rates or November work should not enter October merely because they appear on the same bill.

Why some accruals reverse

Another process reverses a period-end accrual in the next month, then lets the invoice enter through the ordinary purchasing workflow. The reversal offsets the expense that invoice processing would otherwise duplicate.

Consider this separate illustration, not a second set of entries in our October case:

Date and event	Effect on November expense
November 1: reverse a $2,400 accrual	−$2,400
November 10: record a $2,700 invoice	+$2,700
Combined arithmetic effect	+$300

Oracle documents both accruals cleared through invoice accounting and period-end accruals with reversing entries. These are different workflows; the team must know which method applies to an item. Oracle: Perpetual and period-end accrual accounting

The table explains the arithmetic, not which reporting period should absorb that $300 difference. A reasonable estimate revised by new information is different from an error, and an internally locked month is different from previously issued financial statements. Part 7 examines those decisions.

If an accrual reverses but no invoice arrives, the obligation has not necessarily disappeared. The next close must determine whether it remains outstanding and needs recording again. Reversals reduce duplicate-entry risk only when somebody follows the underlying item.

For Maya, the useful close record runs all the way from completed work to estimated obligation to confirmed invoice. The question is: can we show that every relevant cost has been captured, in the right period, exactly once?
