Notice of Error in Shipment and Request for Return Authorization Template

In plain language: Identifies both parties — company names, addresses, contact persons, and the date — so the letter is traceable and reaches the right recipient.

Common mistake: Addressing the letter to a sales rep instead of the accounts payable or returns department — the sales rep often has no authority to issue an RMA, which delays the process.

In plain language: States the purchase order number and invoice number the letter relates to, so the supplier can pull up the transaction immediately.

Common mistake: Omitting the PO or invoice number and relying on a description alone — suppliers process hundreds of orders, and without a reference number, resolution time doubles.

In plain language: States clearly and without ambiguity that a shipment error occurred, giving the date of delivery and the nature of the discrepancy.

Common mistake: Opening with an apology or softened language that obscures the seriousness of the error — this signals to the supplier that urgency is low and response time suffers.

In plain language: Details exactly what was received versus what was ordered — item codes, quantities, specifications — so there is no ambiguity about the nature of the discrepancy.

Common mistake: Using general language like 'wrong items received' without specifying SKUs, quantities, or the difference between ordered and received — vague descriptions allow suppliers to dispute the claim or request additional clarification, adding days to resolution.

In plain language: Lists supporting documents attached to the letter — packing slip, photos of the shipment, delivery note, or bill of lading — to substantiate the claim.

Common mistake: Referring to attachments without actually attaching them — the supplier's returns team will place the request on hold until documentation is received, delaying the RMA.

In plain language: Explicitly requests a Return Merchandise Authorization number and states that the goods will be held pending instructions from the supplier.

Common mistake: Shipping the goods back without first obtaining an RMA — most suppliers refuse returns without one, and unannounced returns are often lost, rejected at the dock, or processed without credit.

In plain language: States whether the buyer wants replacement goods, a credit note, a refund, or a combination — giving the supplier a clear action to take.

Common mistake: Not specifying the desired outcome and leaving it open-ended — suppliers default to the lowest-cost remedy, which may not match the buyer's needs.

In plain language: Sets a specific date by which the supplier must respond with an RMA number or proposed resolution, creating a record if follow-up or escalation becomes necessary.

Common mistake: Omitting a deadline entirely — without one, suppliers treat the request as non-urgent, and buyers have no documented basis to escalate or withhold payment.

In plain language: Closes professionally, confirms willingness to cooperate, and provides contact information for follow-up.

Common mistake: Closing with threatening language in a first notice — escalatory tone in an initial letter can damage the supplier relationship and slow cooperation before formal remedies are even needed.

A notice of error in shipment is a formal business letter a buyer sends to a supplier to document that the goods received do not match what was ordered — whether the wrong item, wrong quantity, wrong specification, or damaged condition. It creates a written record of the discrepancy and formally requests a Return Merchandise Authorization so the goods can be returned and a remedy arranged.

Send it as soon as the discrepancy is discovered — ideally on the same day the shipment is received and inspected. Most supplier return policies set a window of 5–15 business days from delivery for reporting errors. Waiting beyond that window can void your right to a replacement or refund entirely, leaving you holding goods you cannot use.

Yes, in almost all cases. Most suppliers will not accept or process a return without a valid RMA number, and unannounced returns are frequently refused at the dock or processed without credit. The RMA number allows the supplier to track the return, match it to the original order, and issue a credit or replacement efficiently.

Attach at minimum: a copy of the original purchase order, the supplier's packing slip, and photographs of the goods as received. If the damage or error is visible on the packaging, photograph that too. A signed delivery receipt showing the date of receipt further substantiates the timeline of your claim.

Choose based on your operational need. If you need the goods urgently, request replacement with a specific delivery deadline. If the goods are not needed or the supplier cannot fulfill correctly, request a credit note or refund. Specify the remedy clearly in the letter — suppliers will default to whichever option is cheapest for them if you leave it open.

The letter creates the documentary basis for withholding payment on the disputed portion of an invoice, but it does not by itself authorize a unilateral deduction. Review your purchase agreement or supplier terms for the process — many require you to issue a debit memo or invoice dispute letter as a separate step before holding payment. Send the shipment error notice first, then follow up with a formal invoice dispute if the supplier does not respond within the stated deadline.

If the supplier does not respond with an RMA number and resolution proposal by the date stated in the letter, escalate in writing with a demand letter or invoice dispute notice, copy accounts payable, and note that payment on the related invoice will be held pending resolution. Keep every piece of correspondence — the shipment error notice, the deadline, and the non-response — as documentation in case the dispute reaches a formal collections or legal process.

The letter is not a contract or a legal instrument on its own, but it creates a documented paper trail that supports your rights under the original purchase agreement and any applicable commercial law. In most jurisdictions, a written notice of discrepancy sent within the supplier's return window is a prerequisite for exercising your right to return goods or dispute an invoice. Retain a copy of the sent letter and any delivery confirmation.
