Process:

The process of allocating supplier payments is the matching of a payment made to a supplier against the relevant supplier purchase invoice received to flag it as paid. This is not a compulsory procedure and is optional to the user. The process of allocating payments against purchase invoices does not alter any supplier balances it is merely good management of the creditor's ledger.
