3PL invoice audit for ecommerce brands.
We check every billed line — postage, storage, receiving, pick and pack — against your contract and the shipment data. Then we file the claim. You review before anything goes to the 3PL.
What a 3PL invoice audit actually covers
A warehouse invoice is not one number. It is thousands of lines: shipping by zone and weight, pallet storage, inbound receiving hours, pick fees, returns, kitting, and one-off “additional” charges. Most finance teams reconcile the total. The overcharge sits in the lines.
- Postage / shipping — billed service and zone vs the contracted card. Domestic vs international. Weight banding (ceil vs actual).
- Storage — pallet / shelf / bin rates vs the contract, and whether end-of-month snapshots match what you were billed.
- Receiving (WRO / inbound) — hours and pallet assumptions vs what actually landed.
- Pick fees — DTC unit picks and B2B case picks vs UPC / carton size.
- Duplicates and credits — the same shipment billed twice, or a credit that never netted.
How billsharp runs it
We connect to your 3PL (or take invoice exports), reconstruct the month, and only flag lines we can defend with a rate card and a shipment or WRO id. We do not guess missing international cards. We do not claim a month until the last weekly invoice has landed.
You get a draft claim pack (PDF + line evidence). You send — or we send once you approve. Recovery is tracked against credit lines on later invoices.
Who this is for
Ecommerce brands spending enough on a 3PL that a 5–15% error rate is real money. We currently run this in production on ShipBob; the same method applies to any 3PL that bills from a rate card plus shipment data.
