PRO apps
Audits that run on the file, not on opinion.
Each app exists because a specific class of money leaves an organisation through a document nobody re-derived. You hand it your own file; it returns what was charged, what the rule actually was, and which lines do not reconcile.
SpendProof
AI provider invoice ↔ tagged-usage reconciliation
- You supply
- AI provider invoice + your tagged usage export

- Line-by-line reconciliation with an explicit clean-close or withhold verdict
- Failure it catches
- Untagged agent spend that closes the month as a surprise instead of a finding
ParcelProof
Carrier invoice DIM-weight and surcharge audit
- You supply
- Carrier invoice lines + shipment file

CaseProof
Buyer-side audit of a warehouse-automation business case
- You supply
- Vendor's quoted business case + your own cost assumptions

Both deterministic engines on this site stay free and run in your browser. If a decision turns out to need file-level work, the matching app is named on the page that raised it — and nowhere else.
