01Validate the credit document
Record supplier and buyer entities, account, document type, unique number, date, currency, amount, source channel and original file. Review required tax fields with qualified finance or tax owners. Confirm the document came through a validated supplier route. A spreadsheet, chat message or promise to credit is supporting correspondence, not automatically the final accounting document. Search for the same credit received by portal, email, statement or EDI and assign one active record. Verify number sequence and sign without assuming a negative invoice is correctly classified. Preserve attachments and supplier explanation separately from the posted accounting object.
02Link the original cause and documents
Reference invoice and line, PO, receipt, return authorization, debit note, claim, rebate agreement or price correction. State the approved cause and covered quantity or service period. Distinguish commercial goodwill, return, shortage, damage, pricing error, tax correction and rebate because they may require different evidence and posting. One credit can reference several invoices only when allocation is explicit.
03Recalculate line quantity and value
Compare original invoiced, accepted, returned, disputed and already credited quantities using the same unit. Reperform unit price, extension, discount, freight, fee, tax and total under the applicable agreement and policy. Check positive and negative signs and document type. A correct gross total can conceal the wrong product line, currency or tax basis and leave inventory or margin reporting wrong.
04Determine account application
Identify whether the original invoice is open, partly paid or settled. Apply the validated credit to the specified invoice or account under authorization. If a refund is due, record bank and remittance evidence through validated instructions. If future offset is agreed, name the invoice and amount when used. Do not let the credit reduce both an open invoice and a later payment. Check payment proposals and open remittance files before posting so a credit does not arrive after the full invoice has already entered a payment batch. For multi-invoice credits, allocate each amount explicitly and leave the unallocated balance visible.
05Reconcile supplier and buyer records
Compare credit issued, received, posted and applied dates and amounts with the supplier statement and buyer ledger. Trace any debit note or claim that initiated it. Find missing credit, duplicate credit, wrong entity, wrong currency, unapplied balance and a supplier statement that still shows the original invoice in full. Send a line-level schedule rather than an unexplained net balance.
06Resolve tax, currency and residual differences
Use the approved exchange rate and tax treatment for the actual jurisdiction and document date. Keep functional-currency movement separate from the supplier-currency credit. Record rounding and tolerance only under policy. For a partial credit, show original disputed amount, supported credit, amount accepted by each party and residual open dispute with owner, evidence and next date. Distinguish a commercial credit from a tax-only correction, cash discount, rebate or foreign-exchange difference. Do not net unlike causes into one residual. Recalculate the supplier-currency account first, then explain any buyer-ledger translation difference under finance policy.
07Close and prevent recurrence
Confirm the credit is posted once, linked to the correct invoice and operational case, reflected in supplier reconciliation and payment or refund, and excluded from further duplicate application. Close the related debit, return or claim only when its remaining balance agrees. Classify root cause across price, receiving, returns, documentation, product quality or rebate administration and correct the upstream control where recurring.
