Our rate card specifies $42.00 per pallet/month for "Storage - Pallet".
One paragraph, derived
Fourteen checks, each one defensible.
Deterministic rules, not models: every finding traces to exact invoice lines, so it survives the argument with your 3PL.

Amounts come from the sample report on this page. Rules marked clean found nothing in that month, which is the normal result on a correct invoice. Rules marked not checked are the ones the sample report lists under What we could not check and does not count among its checks run: the invoice lines or rate card in that month did not have the data they need, and the report gives the reason for each. Rules marked partly checked did run in the sample report, but only in part: it lists what was left out under What we could not check.
Three lines in. One paragraph out.
Every finding ships as a paragraph citing the invoice, the dates and the amount. Nothing in it was written by hand.

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.

Lines from the same invoice that passed every check. A clean line gets no colour.
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.
Your data, plainly.
- Shopper data
- Names and street addresses are dropped while the invoice is parsed. Of the address, a label keeps only its country and the first three characters of the postal code.
- Raw invoices
- Encrypted with AES-GCM, deleted after 13 months.
- Access tokens
- Used only to read, encrypted at rest, and only the last four characters are ever shown.
- Passwords
- Stored only as a salted hash, never in plain text.
Questions that come up before the first audit.
These are the six we answer most often by email. If yours is not here, ask it in the form below and you will get a person, not a sequence.
- What happens if you find nothing?
- You get the report anyway, showing what was checked and that it came back clean. A clean invoice is a real result: it means your 3PL is billing you correctly and you can stop wondering.
- Do you need write access to our 3PL account?
- No. WareAudit only reads from your 3PL account and never writes to it. ShipBob and ShipHero API tokens carry full account access, so if you would rather not issue one, you can upload invoice exports as CSV instead. Which checks run depends on what your 3PL's data includes, and every report lists the checks it could not run.
- Which 3PLs do you support?
- ShipBob through its REST API and ShipHero through its GraphQL API. Any other 3PL, including ShipMonk, works through CSV upload. CSV is a first-class path, not a fallback we tolerate. One file can be up to 25 MB, about 70,000 invoice lines; a bigger export goes up as weekly or per-warehouse files.
- How long does the first audit take?
- Once the connection is in place, the run takes under a minute for most brands and a few minutes for a month at the Scale ceiling, in the background, with progress on the dashboard. We ask for three invoices so the checks have a baseline to compare against, because most billing errors are only visible as a difference between months.
- Do you take a percentage of what you recover?
- Never. The price is fixed and named upfront. An auditor paid by the size of the claim has a direct reason to inflate the list, your 3PL knows that, and the finding stops being evidence.
- Can I track a dispute after the report?
- Yes. On the dashboard each finding can be marked sent to your 3PL, credit promised, partly credited, credited, declined or withdrawn, and the credit lines on later invoices are matched against what was promised, so you see what came back and what is still owed. A finding that belongs in the letter shows “Dispute by” and a date, counted from the invoice date plus the dispute window on your rate card, and “(passed)” once that day has gone; with no window on the card it says so instead of guessing. The date is for you: it is never in the letter to the 3PL.
- Do you check duties invoices too?
- If your 3PL bills duties separately, upload its Tax and Duties breakdown (.xlsx) and WareAudit checks the duties invoice against it: lines billed twice, totals that do not match the breakdown to the cent, and parcels with no shipping label. That is arithmetic and matching only. Duty rates, product codes and country of origin are not judged, because that is for your broker or accountant, and duty findings keep their own total apart from the warehouse invoices.
- What do you do with our invoice data?
- Shopper names and street addresses are dropped at ingest and never stored at all; of the address, a shipping label keeps only its destination country and the first three characters of the postal code, which is what its zone is looked up by. Raw invoice files are encrypted and deleted after 13 months. Ask us and we will send you everything we hold, or delete your account and actually remove it.
