Accounts Payable
Accounts Payable tracks what your organisation owes suppliers, built directly on the procurement records you're already creating: Goods Receipts and Supplier Invoices.
Where AP comes from
A Supplier Invoice, recorded against a Purchase Order, is what actually creates a payable. There's no separate manual step to "create an AP entry", it flows from the same procurement cycle documented in the Procurement guide.
Three-way matching
Before a supplier invoice is approved for payment, its quantity is matched against the Purchase Order quantity and the Goods Receipt quantity. A mismatch on any of the three doesn't block the invoice outright, it's flagged clearly so someone with the right permission reviews it before payment proceeds.
Note
Recording payments
Once a supplier invoice is matched and approved, payment is recorded against it and posted to the general ledger through the same journal posting mechanism as every other financial transaction, no separate payables ledger to keep in sync.
