Retailer chargeback audit: sort OTIF fines into disputable and not
The Warp retailer chargeback audit takes one deduction or a CSV of retailer chargebacks, checks each one against the fine math, the MABD and arrival dates, the ordered and delivered quantity, and the evidence on file, then tells you what to dispute and what to pull first.
How it works:Drop the carrier’s CSV or PDF, paste rows from Excel, or type one line. Check the column mapping, then read the findings in three tiers: dispute, review, note. Copy the letter.
What this audit catches
Retailers deduct chargebacks from a remittance before a vendor sees them, so the fine is already paid by the time anyone reviews it. This audit runs four checks on every deduction: the fine amount against the stated percent of invoice, the reason code against the MABD, arrival, and quantity fields on the row, the deduction ID against every other row for a duplicate, and the deduction date against the typical dispute window. Whenever a check finds something to dispute, the proof of delivery, appointment confirmation, and arrival scan on file decide whether that finding is ready to send or still needs a document pulled first.
It is built around Walmart’s OTIF program, since that is the one publicly documented rate: 3% of invoice cost for late, early, or short deliveries. Every other retailer runs a different program with a different percent, so this tool asks for that number instead of guessing it.
How to run a chargeback audit
Pull the deduction detail from the retailer portal or remittance statement: retailer name, deduction amount, and reason code at minimum. Add the deduction ID, PO number, and invoice amount when you have them, since the invoice amount is what unlocks the fine math check. Add the MABD or appointment date, actual arrival date, and ordered versus delivered quantity when the reason is late, early, or short. Mark whether proof of delivery, appointment confirmation, and an arrival scan are on file for each one.
Run the whole batch through the CSV upload, paste rows from Excel, or check one deduction at a time through the form. Read the results in three tiers: dispute rows have a documented case and the evidence to back it, review rows need a document pulled before filing, and note rows are informational, often a dispute window that has already closed or a fine that came in under the expected percent.
How Warp bills instead
Retail DC freight still has to hit the appointment, whichever carrier moves it. Warp builds MABD windows into dispatch routing and produces a scan level audit trail on every delivery: appointment confirmation, GPS arrival, dock door scan, and a POD photo with a timestamp. Every Warp invoice is also audited against its own quote before it reaches you, so the freight bill itself never needs this kind of review. When an OTIF or retailer chargeback does land, the evidence to dispute it is already sitting in the dashboard instead of split across carrier portals.
Retailer chargeback audit FAQ
What is a retailer chargeback or deduction?
A retailer chargeback, also called a deduction, is an amount a retailer subtracts from an invoice payment to cover a compliance fine, most often for a late, early, or short delivery. Retailers deduct first and pay the remainder, so the burden is on the vendor to review each deduction and file a dispute for the ones that are not owed.
How much is Walmart’s OTIF fine?
Walmart’s On Time In Full program fines suppliers 3% of invoice cost for a shipment that misses the MABD window, arrives early outside the appointment window, or arrives short of the ordered quantity. That rate applies per instance, so a vendor with frequent misses can lose several percent of Walmart revenue to OTIF fines in a quarter.
Do other retailers use the same 3% rate as Walmart?
No. Walmart’s 3% OTIF rate is specific to Walmart’s supplier program. Target, Amazon, Kroger, and other retailers each run their own compliance program with a different percent, different reason codes, and a different dispute window. This tool treats every retailer other than Walmart as custom: enter that retailer’s own percent before trusting the fine math check.
What evidence do I need to dispute a chargeback?
Most disputes need three things: proof of delivery, appointment confirmation, and an arrival scan or GPS timestamp. A dispute filed with all three tends to win. A dispute filed with one or none of them is usually rejected on the first pass, even when the underlying fine was wrong, so pull the missing evidence before filing rather than after.
How long do I have to dispute a chargeback?
Dispute windows vary by retailer and are set in that retailer’s supplier agreement or portal, typically somewhere around 30 to 90 days from the deduction date. Treat any number here as a starting point to confirm, not a universal rule: miss the window and most retailers will not reopen the case regardless of how strong the evidence is.
Why would a "late" chargeback be wrong?
A late chargeback is worth disputing whenever the actual arrival date was on or before the MABD or appointment date on file. This happens more often than it should: appointment reschedules that the fine calculation never picked up, a scan logged against the wrong leg, or a retailer system that used the original PO date instead of an approved reschedule.

Warp’s appointment discipline and scan trail turn a chargeback dispute into a dashboard query, and every invoice is already audited against its quote.
