WarehouseAudit
Your 3PL is probably billing you for work it didn't do
Pick fee stacking on bundle orders. Storage billed at peak snapshot rather than daily average. Carrier surcharges triggered by conveyor sensor errors. Most UK brands absorb these without knowing. We audit your 3PL and carrier invoices against your contracted rate card and find the discrepancies. You pay nothing unless we recover money.
Send us your invoices
One month's 3PL invoice and your rate card. That's enough to find the first discrepancies.
We find the discrepancies
We cross-reference every line item against your contract. Pick stacking, storage variances, carrier accessorials — we flag every one with evidence.
You get a credit dossier
A documented evidence pack ready to submit to your account manager. It goes to your account manager in your name — the relationship stays yours.
We take 30% of what's recovered
Only when money lands back in your account. Zero risk, zero upfront.
Case register
Documented, publicly verifiable reports of carrier surcharge disputes. Linked at source — no invoice totals are claimed unless directly quoted in the source.
- UK Business Forums — "Royal Mail Theft By Surcharge"
Carrier: Royal Mail · Confidence: High — link verified
Ongoing thread of sellers disputing surcharges for "unreadable barcode" and "label applied incorrectly" — includes a seller who measured barcodes as compliant (25–26mm) and was still surcharged, and a £2.50 "label applied incorrectly" charge on a parcel the seller could see was correctly labelled in the carrier's own tracking photo. Sellers report this is a recurring issue tied to the "Horizon" barcode-scanning machines.
- John & Ginger — "Avoiding Royal Mail 'Incorrect Label' Surcharges: A Guide for Small Businesses"
Carrier: Royal Mail · Confidence: High — link verified
A business received weekly ~£5/parcel surcharges for "unreadable"/"incorrectly applied" labels on Tracked 24/48 parcels; one photo "proof" supplied by Royal Mail didn't even show their box. Charges stopped only after switching to a box shape that keeps the label flat and centred, away from edges/joins.
- Amazon Seller Central Forums (Europe) — "Royal Mail Incorrect Format Charges - Warning"
Carrier: Royal Mail · Confidence: High — link verified
Multiple sellers report batches of "incorrect format" (LL) surcharges on parcels later confirmed to be within size/weight guidelines; one seller reports a single 160g mis-weighed item caused surcharges to be applied across an entire batch of otherwise correctly-weighed items.
