Frequently Asked Questions
Everything you need to know about warehouse billing audits, security, and dispute resolution.
• What warehouse billing errors does Audit3PL catch?
We audit duplicate order pick fees, carrier dimensional weight integer rounding discrepancies (LxWxH / 139 with ceil rounding), unauthorized off-season peak surcharges (e.g. holiday fees billed in July), contract rate tier creep, and line extension variances (Qty × Rate mismatches).
• Is our proprietary warehouse invoice data secure?
Yes. All files are encrypted with TLS 1.3 and processed in isolated US cloud environments. Under our 24-hour auto-purge policy, all uploaded invoices and generated reports are permanently deleted after 24 hours. Data is never used for AI training.
• How does the 100% Money-Back Guarantee work?
If our audit does not identify valid, verifiable discrepancies in your monthly warehouse invoice, or if your 3PL account manager substantiates that the flagged items were billed according to your contract, we provide an immediate 100% refund.
• How do I submit the dispute to my 3PL warehouse?
Once unlocked, you can download a complete Excel ledger with dynamic audit recalculation models and line extension proofs, alongside a ready-to-send formal credit memo dispute notice for your warehouse billing department.
