To record an invoice payment accurately, a source document is essential for verifying the transaction. Common examples of these source documents include receipts, vouchers, and payment advices.

Receipts serve as proof of payment received from the customer or client. Vouchers provide authorization for the payment, often detailing the invoice number and payment amount.

Matching Source Documents with Invoices: Why It Matters

Accurately recording an invoice payment requires identifying the correct source document that validates the transaction. Matching source documents with invoices ensures financial records are precise and verifiable.
