Problems With Direct Fulfillment: Chargeback Prevention Guide
This guide covers the two chargeback types tied to direct fulfillment order handling: order cancellation rate, and ship method mismatch. For each chargeback, you'll find what triggers it, how to avoid it, the current rate card, and the documentation Amazon requires if you need to dispute a charge.
1. Cancellation Rate Chargeback
You may receive a chargeback if you cancel an order — either because you denied an order that Amazon submitted (formerly known as fill failure), or because you began to fulfill an order but could not complete it (formerly known as floor denial). These chargebacks exist to ensure reliable order fulfillment and accurate inventory availability.
What triggers this chargeback
Triggered when you cancel an order, either by denying an order Amazon submitted (fill failure), or by starting fulfillment but failing to complete it (floor denial). The root cause is typically inaccurate inventory data in your system.
Rate: $10 per cancellation issue.
Exceptions
No chargeback if the cancellation was caused by Amazon (e.g. Amazon-initiated PO cancellation or a system error). Note: a high cancellation rate can negatively impact your performance metrics and may lead to warehouse or account suspension.
How to avoid this chargeback
- Maintain accurate warehouse inventory to reduce the chance of receiving an order you can't fulfill.
- Update available inventory at least once every 24 hours, per warehouse.
- Proactively flag stock-outs and adjust available quantities before Amazon submits a PO you cannot fulfill.
Rate card
| Chargeback type | Trigger scenario | Rate | Key requirement |
|---|---|---|---|
| Cancellation Rate | Fill Failure (order denied) | $10 per issue | Accurate inventory; update every 24 hrs |
| Cancellation Rate | Floor Denial (fulfillment incomplete) | $10 per issue | Accurate inventory; update every 24 hrs |
Required documentation for dispute
- Justification
A clear justification for the order rejection explaining why the cancellation was not due to your inventory inaccuracy (e.g. Amazon-initiated cancellation, duplicate PO, system error).
- Supporting documents
Case Number, date of rejection and submission, PO Number, and ASIN/SKU(s) affected. Attach any Vendor Central screenshots or case correspondence that supports your claim.
Approved submission
PO-7203948 was a duplicate purchase order submitted by Amazon for the same ASIN — the original PO was already confirmed and shipped. Vendor inventory was accurate; the cancellation was due to Amazon's duplicate PO, not stock unavailability. Dispute includes Case Number, PO Number, ASIN, and rejection/submission dates.
Denied submission
Submission is missing the Case Number, ASIN, and rejection date. Justification confirms the items were out of stock at the time of the order — a vendor-side stock-out with no valid basis for dispute.
2. Ship Method Mismatch Chargeback
You may receive a chargeback if you shipped an Amazon order using a different carrier or a different ship method from the one specified in the order. These chargebacks exist to ensure shipping consistency, cost accuracy, and reliable delivery performance across Amazon's supply chain.
What triggers this chargeback
Triggered when an order is shipped using a different carrier or ship method than the one Amazon specified. The assigned ship method must be followed exactly — any unauthorized change to carrier or service level triggers this chargeback. Common causes: the warehouse isn't set up for the assigned carrier, shipment priority was changed without approval (e.g. standard to priority), or the EDI ASN references a different ship method name than the one in the order.
Rate: $10 per ship method mismatch issue.
Exceptions
No chargeback if the carrier rejected the shipment due to product dimensions or weight exceeding the assigned method's limits — a carrier rejection notice must be provided. Note: continued non-compliance puts your website availability at risk.
How to avoid this chargeback
- Always use the carrier and ship method assigned by Amazon — switching to another carrier, even a comparable method, is not allowed without approval.
- Never change shipment priority (e.g. standard → priority) without explicit approval from your Vendor Manager.
- Ensure the EDI ASN matches Amazon's ship method name exactly — e.g. if the order specifies UPS_2ND, any other method name in the ASN triggers this chargeback.
- If a product doesn't correctly reflect the assigned ship method, contact your Vendor Manager immediately with complete package dimensions (L × W × H) and weight.
Rate card
| Chargeback type | Trigger | Rate | Key requirement |
|---|---|---|---|
| Ship Method Mismatch | Wrong carrier or service level used | $10 per issue | Use Amazon-assigned carrier & method exactly |
Required documentation for dispute
- Product description
The product description and ASIN for the affected item(s) — identifying which product was shipped with the wrong method.
- Actual dimensions
The actual dimensions and weight of the product (L × W × H and weight) — proving the item exceeded the assigned carrier's size/weight limits.
- Carrier rejection
Carrier rejection notice or system screenshot showing the assigned carrier refused the shipment due to size, weight, or eligibility — proving the method change was unavoidable.
Approved submission
Dispute includes ASIN, product description, and actual dimensions (36×24×18 in, 72 lbs). UPS rejection notice proves the item exceeded the assigned Ground SP weight limit of 70 lbs — the method change was unavoidable.
Denied submission
Submission is missing actual dimensions and weight, and provides no carrier rejection notice. Vendor admits to voluntarily changing the ship method to FedEx Freight without Amazon approval — no valid basis for dispute.
