Subject: ShipBob billing discrepancies for 2026-07, $2,198.84 to review Hello, We reconciled NW-2026-05, NW-2026-06, NW-2026-07 against our rate card and the preceding invoices and found 7 discrepancies totalling $2,198.84. Details below, each with the specific line items. 1) The charge "Fulfillment Adjustment Surcharge" of approximately $285.00 has appeared on every invoice from 2026-05 through 2026-07 (3 months, $855.00 in total). It is not part of our rate card and was never quoted. Please identify its contractual basis or credit $855.00. 2) Our agreement defines peak surcharge windows as 2026-11-01 to 2026-12-31. Invoice NW-2026-07 bills peak surcharges totalling $420.00 on 2026-07-18, outside those dates. Please credit $420.00.
Fixed price, named upfront.
We never take a percentage of what we find. An auditor paid by the size of the claim has a reason to inflate it, and you would be right not to trust one.

Straight about the numbers
We will not quote a statistic we cannot stand behind.
Industry claims that brands leak 3-15% of fulfillment spend are vendor-reported; no independent study exists, and we will not pretend otherwise. Our own number will appear here once the first audits are done, and it will replace this caveat.

What we are not.
Not a carrier audit. UPS and FedEx invoices are a different trade. We audit the warehouse: pick, pack, storage, receiving, returns, surcharges.
Not advice to switch 3PLs. Moving costs more than the findings. You need the money back, not a migration.
Not for 50,000+ orders a month. That segment belongs to Implentio, from $1,000 a month. If that is you, go there; it is the honest answer.
Your data, plainly.
- Shopper data
- Never stored. Names and addresses are dropped while the invoice is parsed.
- Raw invoices
- Encrypted with AES-GCM, deleted after 90 days.
- Access tokens
- Read-only is enough, and only the last four characters are ever shown.
- Passwords
- None exist. Sign-in is a one-time link that expires in 15 minutes.
