How Margin Pro helps 1P vendors recover 8 Amazon claim types

Most Vendor Central disputes start the same way. Amazon short-pays an invoice, someone on your team spots it weeks later, and the hunt for paperwork begins. By then, the physical inventory trail has usually gone cold.

Shortages are just one of several ways Amazon can end up owing you money. Margin Pro helps 1P vendors recover eight, from familiar ones like chargebacks and price claims to newer ones like Active Receiving Claims, Overages, and Past Due Invoices. Active Receiving Claims get filed while the purchase order is still open, which changes how Amazon reviews them. We’ll get to why shortly.

First, the full lineup. Here’s what each claim type is and what it takes to win it back.

The 8 claim types at a glance

Every claim type comes down to a gap between what you shipped, what Amazon says happened, and what Amazon paid. The evidence that closes the gap differs for each one.

Active receiving claims

Shortage disputes usually happen after the payment due date. Active receiving claims flip that order. 

Margin Pro files them proactively, ahead of the due date, while the PO is still open and active in Amazon’s receiving network.

Why early filing works 

Amazon’s automated systems often deny shortage claims that are perfectly valid. That happens even when your proof of delivery and bill of lading show every unit arrived. A denial from a system that never looked at your pallets isn’t a verdict on your shipment.

Filing during the active window gets around that automated review. It pushes fulfillment centers to run a physical bin check, and they run it before the physical inventory trail goes cold. A person looking at actual bins is a very different reviewer from a rules engine looking at a mismatch. This approach improves the win rate on claims that automated systems would otherwise reject.

What to know before you file

These claims need their own tracking. Because they get paid early, the funds can face automated clawbacks during later audit cycles. If you handle claims in-house, keep active receiving claims in a separate log so a clawback doesn’t catch you off guard.

Two more claims that slip through unpaid

Overages

Despite the name, this one is money owed to you. An overage happens when Amazon’s records show it received your inventory, but it never paid for those units. Nobody disputed anything. The payment just never happened.

It’s a purely internal data gap, and the recovery amount is simple: received units minus paid units, once they’ve sat unpaid past the standard 90-day settlement window.

Past due invoices

You submitted a valid invoice, the due date passed, and Amazon didn’t pay. The money sits on hold. 

These invoices become eligible for dispute the moment the due date passes, and many get resolved at first through automated submissions that need no documents.

Other claim types that should be on your radar

Shortages

A shortage means Amazon paid less than you invoiced because it says it didn’t receive the full quantity. This happens in two ways. Sometimes Amazon’s own receiving records show the units arrived, yet it short-pays anyway. Other times Amazon claims it received nothing at all, and you need outside proof such as a bill of lading or proof of delivery.

Either way, recovery depends on lining up your delivery evidence with Amazon’s receiving metrics and your ASNs (advance shipment notifications).

Operational chargebacks

Amazon charges vendors for alleged operational failures. The usual suspects are receiving accuracy, in-full delivery, on-time shipment, and PO on-time accuracy (POTA). Some of those charges are fair. Plenty aren’t.

Disputing them means tracking each chargeback window and backing your case with specific evidence that you met the requirement. Miss the window, and the evidence doesn’t matter.

Quick pay discounts

Say your terms are “2% Net 30.” Amazon takes the 2% early-payment discount from your payout, then sends the payment after the discount window has closed. You gave up the discount without getting the speed.

To prove it, you compare the payment terms on the PO with the actual payment timeline: the actual payment date against the true baseline date. If Amazon paid late, the discount wasn’t earned.

Price claims

Amazon sometimes short-pays an invoice by saying the unit cost is lower than what you billed. The usual justification is an active co-op agreement or a temporary promotional price.

To win these, you show that your invoiced price exactly matches the accepted PO price and that no price protection agreements were active during the period.

Returns

When Amazon returns inventory to you through a return buyback, it deducts a charge for the trip. Sometimes the carrier loses the shipment before it reaches your receiving facility. You then lose twice: the deduction and the inventory.

Amazon is the shipper of record on these returns, so the transit risk is theirs. A dispute needs stalled carrier tracking plus a warehouse affidavit of non-receipt.

Why in-house teams miss so many of these

Manual review catches the obvious deductions. The subtle ones pile up below the review line while dispute windows close. Across hundreds of POs, that adds up. Threecolts data puts it at 2 to 5% of revenue that 1P vendors typically lose to unclaimed deductions.

Each claim type has its own evidence, its own timeline, and its own way of getting denied. A team that chases one or two types leaves the rest on the table. 

How Margin Pro recovers these claims for you

Margin Pro monitors more than 45 claim scenarios across the retailers, marketplaces, and carriers you work with. For 1P vendors, that means it surfaces what should be filed, shows a countdown before each window closes, and checks every invoice and proof of delivery against marketplace requirements before filing. From there, it files, tracks, and re-files until you get paid.

Setup is a guided, read-only connection to Vendor Central that typically takes about 15 minutes. You don’t change how your team works. Pricing is performance-based, with no upfront fee and no subscription. You pay a pre-agreed share of what Margin Pro recovers, and nothing if it finds nothing. Vendors typically see their first recovery in about 4 weeks.

Threecolts has saved Amazon and Walmart vendors over $360M to date.

Most vendors have money sitting in more than one of these categories, and active receiving claims work best when someone files them before the PO closes. Margin Pro’s team reviews your Vendor Central account, shows you what’s recoverable, and you only move forward if it’s worth it.
