For Procurement & Operations
Upload two versions of a supplier quote, contract, or purchase order and see every change — amended prices, revised delivery terms, added clauses. Know what changed before you countersign.
See it in action
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.
Why no AI
Compare Files uses a deterministic, logic-based engine — not a language model. It reads both files and reports every change that is actually there. It can’t summarize away a deleted line, invent a difference that isn’t in the file, or “mostly” get a number right. What you see is exactly what changed — nothing added, nothing missed. For quotes and purchase orders, that means no AI overlooking a changed price or delivery term.
Your files never leave your device. Everything runs in your browser — no uploads, nothing stored.
No AI, so no hallucinations. A deterministic engine reports every real change and never invents one.
No upload, no server wait. Comparisons run locally and keep working offline once the page has loaded.
FAQ
Yes — upload two supplier quote documents (PDF or DOCX) and instantly identify where prices, quantities, payment terms, or delivery conditions differ. Spotting a line-item discrepancy before issuing a purchase order is exactly the workflow this is built for.
Yes — compare PDF or DOCX documents side by side to check that invoice amounts, quantities, and terms align with the PO. Catching a mismatch before payment approval prevents overpayment and keeps your audit trail clean.
Yes — upload two CSV or Excel files to compare structured supplier data: pricing sheets, bid comparisons, or contract terms in tabular format. This covers the cases where supplier data arrives as a spreadsheet rather than a formal document.
No — all comparison happens locally in your browser. Sensitive supplier pricing, contract terms, and purchase order details never leave your device and are never stored or transmitted to any server.
