Deduction type
Duplicate deductions
The same deduction taken more than once — on one invoice, across invoices, or as both a chargeback and a short-pay. Highly recoverable because it's a pure paperwork error.

A duplicate deduction is the same charge taken more than once. The duplication takes three common forms: the same reason code appearing twice on a single remittance, the same charge split across two separate invoices or two different deductions (for example, a shortage taken both as an OS&D line and again as a short-pay against your invoice), and a charge that was already disputed and reversed showing up again months later.
Duplicates are among the most recoverable deductions because they're pure arithmetic errors — there's no judgment call, just two entries for one charge. Finding them requires matching every deduction back to a source document and checking whether the amount or reference number has already been claimed.
They also tend to hide in plain sight: same dollar value, different reason codes; or the same reason code, different amounts that add up to one charge. Line-by-line reconciliation against invoices and credit memos is what surfaces them — and that's exactly the work most brands don't have time for.

Frequently asked questions
What is a duplicate deduction?
It's the same charge taken more than once — the same reason code twice on one remittance, one charge split across two invoices or deduction types, or a previously disputed and reversed charge that reappears.
How do I find duplicate deductions?
Reconcile every deduction line back to a source document and check whether the amount or reference number has already been claimed. Watch for the same dollar value under different reason codes, or different amounts that sum to one known charge.
Are duplicate deductions easy to recover?
Generally yes, because they're pure paperwork errors — there's no dispute over whether the charge was valid, just proof it was taken twice. You still must file within the buyer's dispute window.
Other deduction types
- Shortage deductionsA charge for units the buyer says it didn't receive against your invoice — one of the most recoverable deduction types because it turns on delivery documentation.
- Manufacturer chargebacks (MCB)A promotional discount a distributor gives a retailer and bills back to the manufacturer — often with a processing fee on top.
- Pricing & deal discrepanciesShort-pays where the buyer paid a different price than invoiced, or applied a deal you didn't agree to — among the most recoverable deduction types.
- Fill-rate / service-level penaltiesA penalty for shipping fewer units than were ordered — distinct from a shortage at receiving, and typically a percentage of the shorted value.
- Co-op advertising (co-op) deductionsA deduction taken to recover advertising or marketing spend the buyer claims to have run on your behalf — recoverable when the spend wasn't approved, documented, or was billed twice.
- Returns / RTV deductionsA deduction for product the buyer returned — unsold, damaged, or non-conforming. Usually legitimate; recoverable mainly when the return wasn't authorized or was double-counted.
- Post-audit deductionsCharges raised by an auditor reviewing past invoices — often months after the transaction. Recoverable when the audit's claim is wrong, undocumented, or falls outside the dispute window.
- Unearned / unauthorized cash discount deductionsA prompt-payment (terms) discount the buyer took without actually earning it — paying late but still deducting the discount, or taking a rate it wasn't entitled to. Among the most recoverable deductions.
- Promotional billback / scan-down deductionsDeductions that recover promotional discounts — billbacks, scan-downs, off-invoice and temporary price reductions. Recoverable when unauthorized, mis-keyed to the wrong dates or SKUs, or billed more than once.
- Slotting / new-item / free-fill deductionsFees charged to place a new item — slotting, new-item, placement, and free-fill (free initial cases). Often contractual, but recoverable when duplicated, charged beyond the agreement, or taken for items never stocked.
- Spoilage / swell / unsaleables deductionsDeductions for damaged, expired, or unsellable product — spoilage, swell, and unsaleables. Usually valid within an agreed allowance; recoverable when they exceed the allowance, aren't documented, or are duplicated.
- Freight / backhaul / detention deductionsShipping-related deductions — backhaul allowances, detention, lumper fees, fuel, and freight-audit charges. Recoverable when applied on the wrong freight terms, at the wrong rate, or duplicated.
