Customer transactions are the financial documents at the heart of accounts receivable — invoices, credit memos, and debit memos. FAR models these using a header/line pattern: a transaction header carries document-level details, while transaction lines hold the individual line items.
Supplier transactions are the financial documents at the heart of accounts payable — invoices, credit memos, debit memos, and prepayments received from suppliers. FAP models these using a header/line pattern: a transaction header carries document-level details, while transaction lines hold the individual line items. This mirrors the header/line pattern used for customer transactions in FAR.
