Amazon Vendor chargebacks: the most common causes and how to reduce them

Operational chargebacks are small penalties, sometimes just a few euros, that Amazon applies when a shipment doesn’t meet its requirements. One at a time they look trivial; added up over a year they hit your margin. Here are the most common causes, how to read them in Vendor Central, which ones to dispute and how to stop them at source.

What operational chargebacks are

Amazon receives thousands of shipments every day. To process them automatically, it asks Vendors to follow precise rules on shipment notifications, labels, packaging and deliveries. When a rule isn’t followed, the fulfilment centre has to step in manually, and Amazon charges the Vendor for that extra handling. That charge is the chargeback.

Don’t confuse them with shortages, which concern goods invoiced but not logged at receiving, or with co-op and allowances, which come from your commercial terms. Chargebacks are penalties linked to how you ship, not what you sell.

The most common causes

There are dozens of types, but most chargebacks fall into a few families:

ASN: the most sensitive point

The ASN (advance shipment notification) tells Amazon what’s on its way: which codes, how many units, in which cartons and pallets. If the ASN doesn’t match what physically arrives, the fulfilment centre can’t receive it automatically. The most typical errors are quantities not updated after a last-minute change, cartons declared differently from how they were packed and ASNs sent after the goods have left. An accurate ASN reduces chargebacks and makes shortages easier to dispute.

Labels and packaging

Every carton and pallet needs the required labels, readable and in the right place. A strip of tape over the barcode or a badly printed label is enough to trigger a penalty. The same goes for carton weights and dimensions: beyond certain limits the fulfilment centre has to handle them manually. The exact requirements are in the Vendor Central guides and change over time, so whoever prepares your shipments should check them regularly.

Delivery appointments

Deliveries to Amazon fulfilment centres are by appointment. Arriving without a booking, late or in a different slot from the confirmed one can trigger chargebacks. Often the problem lies in how information passes between Vendor and carrier: the appointment exists, but the carrier doesn’t know about it or doesn’t stick to it.

How to read them in Vendor Central

Chargebacks are in the operational performance section of Vendor Central. For each one you’ll see the type, date, linked PO or shipment and amount. The first useful step is to download a few months of data and group it:

1. By type, to see which errors keep coming back.
2. By destination fulfilment centre, to see whether the problem is concentrated.
3. By carrier or dispatch site, if you use more than one.
4. By amount, to see where the cost is concentrated.

It often turns out that two or three causes explain most of the spend. That’s where to act first.

Which chargebacks you can dispute

You can dispute a chargeback when you have proof that the error didn’t happen or wasn’t your fault. Some typical cases:

• ASN sent on time, with proof of transmission and contents matching the goods.
• Delivery made within the booked slot, with proof from the carrier.
• PO confirmed correctly, with date and quantity recorded.
• Penalty applied twice for the same event.

You open the dispute in the same section of Vendor Central, chargeback by chargeback. The windows are tight: usually around 30 days from notification, with the option of a second dispute after a rejection, but check the exact terms in Vendor Central for your marketplace. Without precise evidence the dispute will be rejected, so keep ASNs, order confirmations and proofs of delivery filed neatly for every shipment. If volumes are high, a Vendor recovery service can handle these disputes alongside shortages and price claims.

How to reduce them with your logistics and warehouse teams

Disputing helps, but the real savings come when chargebacks stop happening. Some actions that deliver concrete results in the projects we run:

• A shipping checklist for the warehouse, with Amazon’s requirements on labels, weights and packaging, updated whenever the rules change.
• System-generated ASNs based on what was actually packed, not typed in by hand.
• Appointment checks: the carrier receives the booked slot and confirmation for every shipment.
• Clean master data: EAN codes, dimensions and weights aligned between your ERP and Vendor Central.
• A monthly chargeback review with whoever runs logistics and the warehouse, looking at causes and not just the total.

A practical tip: whenever you change something in the process, such as a new carton format or a new carrier, check the chargebacks over the following weeks. New penalties often appear right after a change that seemed harmless. Spotting it straight away costs little; spotting it three months later costs a lot more.

If you use a third-party logistics provider, share the chargeback data with them. Many don’t know what their mistakes cost until they see the numbers. If your contract allows it, consider passing documented chargebacks caused by their errors back to them: it’s the fastest way to align interests.

What to do now

Download the last three months of chargebacks and group them by cause. Identify the two or three most expensive items and set up a meeting with your warehouse and logistics teams to understand where they come from. Set up evidence filing for every shipment so you can dispute on time. If you’d like an outside view of how your account’s operations are performing, you can start with a free Amazon audit.
