A vendor's business case is built on a blended wage, ideal utilisation and the lines their quote does not carry. Paste the quote's own line items and your numbers, and CaseProof re-runs the proposal through the same engine as your case — then says which assumptions have to be confirmed in writing before you sign.
Paste or upload the quote's own line items as CSV rows. Every value is echoed as the vendor wrote it — CaseProof never re-prices a line, and a line the quote leaves blank is reported unpriced, not $0.
The bid structure, your staffing sheet and your tax position as JSON. Money is integer cents; a term you do not state is reported unstated and blocks a pass — it is never filled in for you.
Worked scenarios: every number is a stated input, and the vendor's claims are reproduced by the same engine that audits the buyer's case.
Agent surface: audit_automation_case, compare_automation_bids and after_tax_payback are registered as WebMCP tools and advertised in /.well-known/mcp.json.
