Supplier Prepayment Reconciliation

A buyer advances money for a future supplier delivery, and when invoices and receipts arrive the advance must be applied correctly so the buyer does not pay twice or leave an unexplained balance. Supplier prepayment reconciliation compares the disbursed advance, accepted performance, invoices and recorded application under the contract.

Identify the original advance by matching bank payment, supplier, contract, purchase order, currency and reference number, since similar supplier names are not enough. Check the purpose, because a security deposit, refundable retainer and advance against specific goods can follow different application rules, so read the actual agreement, and verify actual payment, since a failed bank payment is not an advance to apply.

Check receipt evidence, as goods receipts, service acceptance or signed milestones establish what performance can be matched under the agreed process. Review the supplier invoice, which should show the gross amount, taxes where applicable, and how the advance is applied or credited, checking local invoice rules rather than assuming one format globally.

Use the agreed application sequence, since some contracts apply a fixed percentage to each milestone while others apply the whole balance to the final invoice, and do not allocate by convenience. Track partial application, because one advance may cover several invoices, each application reduces its open balance, and the total cannot exceed the actual advance without a separately authorised adjustment.

Avoid double payment, since if the accounts payable system pays the gross invoice while ignoring the advance credit the buyer may send excess cash to the supplier. Check supplier statements by comparing the supplier's view with the buyer's ledger, but do not assume a statement is correct when underlying documents conflict.

Reconcile currencies, since a payment in one currency and an invoice in another may require contractual conversion and accounting treatment, and no exchange rate should be invented; under IFRS, IFRIC 22 addresses foreign-currency advance consideration, and its exchange-rate guidance is distinct from the operational task of matching cash and invoices. Separate tax treatment, as VAT, sales tax and withholding rules depend on jurisdiction and transaction facts, so finance should verify dates and amounts before an adjustment.

Look for credit notes, since a cancelled order may require a refund or valid credit against another order, subject to agreement, and a credit note alone is not cash recovery. Investigate stale balances, because an advance that remains open after all goods are accepted can signal missing invoice application, overpayment or data-entry error.

Check supplier changes, since a parent company and subsidiary may have different legal rights and an advance should not be offset with an invoice from another entity without verifying authority, and preserve revisions so that if a contract changes scope the original advance and documented reallocation approval are retained. Separate promises from settlement, because supplier assurances that the next invoice will offset the amount do not close the ledger today, and use a suspense category carefully so unmatched balances stay visible and aged, not buried in a generic clearing account.

Match totals: the opening balance plus new payments less valid applications and verified refunds should equal the closing open balance, adjusted only for documented corrections, and review timing, since a late invoice may be a normal cycle issue but can obscure an overdue delivery. Set ownership (procurement verifies the contract and acceptance, accounts payable checks invoice application and treasury verifies the bank movement), sample posted entries to confirm the ledger matches the reconciliation, and close with evidence, because a reconciled zero balance should trace to accepted invoices and cash or credits, not to a manual write-off without support; APQC's invoice-to-purchase-order matching measure concerns a related control, but it does not prove that a prepayment was applied to the final payable.
