For Procurement & Operations
Compare supplier quotes side by side, track contract revisions, and verify purchase orders against invoices. Every price change and clause amendment highlighted. Files stay private.
Use cases
Compare a revised quote against the original. See exactly which line items changed price, what was added or removed, and what the net difference is.
Track every clause amendment across rounds of negotiation with a supplier. Know exactly what changed before signing the final version.
Compare the invoice received against your approved purchase order. Catch discrepancies in quantities, unit prices, and line items before approving payment.
Privacy
Pricing agreements and supplier contracts are commercially sensitive. We have no technical ability to see your documents — all comparison happens locally in JavaScript inside your browser. There is no server receiving your files.
Compare Files works entirely in your browser. There is no server that receives, processes, or stores your file data. Not because we promise not to look — but because we architecturally cannot. All comparison logic runs locally in JavaScript.
Document comparison unlocked with a one-time $9 payment. No subscription, no per-file fees.
