The claim is not a lie; it is arithmetic on different inputs. CaseProof re-runs the proposal through the same engine first — reproducing the 14 months — then applies the buyer's reality one group of inputs at a time: the headcount that actually goes, the fully loaded rate, turnover, the ramp, maintenance, the omitted one-time lines, the uptime nobody promised, and the buyer's own tax position. The chain ends exactly on the audited payback, so no month of the gap is unexplained.
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.
