01Identify document purpose and authority
Record debit-note or chargeback number, issuer, recipient, currency, issue date and approval owner. State whether it requests supplier agreement, records a buyer deduction, disputes an invoice or confirms a settlement. Cite the agreement, PO or policy clause relied upon. A reason code from a system does not create a contractual right, and a buyer-issued debit note is not automatically accepted by the supplier.
02Tie the claim to one event
Link invoice and line, PO and line, receipt, inspection, shipment, return authorization, damage claim or service milestone. Record event date, location, SKU, lot, quantity and affected amount. Split unrelated incidents into separate claims. If one delivery created both shortage and damage, preserve separate quantities so the same units cannot support two full deductions.
03Build the evidence packet
Use receiving records, signed counts, photographs, inspection findings, transport evidence, return tracking, supplier acknowledgments and approved specifications as relevant. Preserve originals and timestamps. Identify what is confirmed, alleged or missing. Evidence should support the event, quantity and responsibility; a dashboard summary or buyer assertion alone does not prove supplier liability.
04Recalculate the commercial amount
Start with affected accepted or rejected quantity and the applicable unit price, allowance, penalty or service rate. Separate product value, freight, handling, tax and administrative charges. Apply prior credits and recoveries. State rounding and currency basis. Never calculate against retail selling price, marketplace display amount or an unsupported consequential-loss estimate unless an authorized agreement and qualified review permit it.
05Provide notice and supplier response
Send a unique claim with evidence, proposed treatment, response deadline and contact. Record delivery and supplier acknowledgment. Allow the response path defined by the agreement: accept, request evidence, propose a correction, dispute responsibility or offer another settlement. Keep urgent containment or return instructions separate from final liability so operational action is not delayed by accounting debate.
06Approve and post the settlement
Record buyer and supplier positions, authorized conclusion and document type needed: debit note, supplier credit note, corrected invoice, refund, replacement, approved offset or no adjustment. Finance should post the final treatment once and link it to the original invoice and remittance. Unilateral short payment can create a supplier-account difference even when the underlying operational complaint is valid.
07Close without duplicate recovery
Search related returns, freight claims, insurance, customer credits, replacement shipments and prior deductions. Reconcile buyer and supplier ledgers and statement balances. Record closed, reversed, partly accepted or still disputed status. Feed recurring cause into supplier performance or corrective action, but do not keep a financial claim open merely to force operational improvement.
