How to Read Your Deduction Report

Most suppliers I talk to have never really read their deduction report. They see the total, wince, and move on.

Which is fair. That report is written for the retailer's AP team, not for you. But there's money in it, and an afternoon gets you most of the way.

Sort by dollars, not by line count

Everyone opens the export, sees two hundred small deductions and four big ones, and starts on the two hundred. The money is almost always sitting in one or two codes.

The reason code is a symptom

"Late ASN" tells you what the retailer saw. It doesn't tell you why. I've watched that one code come from a 3PL transmitting on end-of-day batch instead of at truck departure, from a carrier pickup that quietly drifted later, and from a warehouse that ships before it scans. Same code, three completely different fixes.

Pull five real examples per code and trace each back to the actual PO, the actual shipment, the actual document. Slow bit. Also where the answer is. Five is usually enough for a pattern to show.

Work out whose fault it actually was. Some are yours. Some are your 3PL's. Some are the retailer charging against their own bad item data. You can't dispute what you haven't separated.

The clock isn't the same for every code

Then check the clock, per code, because the windows aren't uniform and this catches people. Walmart gives you up to 24 months on general AP deductions and 12 on shortages, but AP chargebacks in the dispute portal are 15 to 30 days from posting. Target will look at an AP deduction 18 months out, while a compliance violation gives you about two weeks to file an exemption before it's locked for good. Amazon wants disputes inside 30 days of the chargeback showing up in Vendor Central.

So the ones with the shortest fuse are the compliance deductions. Which are also the ones that need the most digging. That's not a coincidence, and it's why they go unchallenged.

Worth knowing, only about 20 to 30% of deductions ever get disputed at all. Of the ones that do, roughly 40% come back.

It's a reconciliation, not a mystery

Underneath all of it, a deduction report is a reconciliation between what your customer believes and what your system says. You're already receiving it. It just arrives months late, with the money already taken, and a reason code too vague to act on.

Doing that reconciliation yourself, early, is the whole game.
