Parts & Quotes helps small hardware teams, manufacturers and buyers compare two flat bills of materials or check one supplier quote against a required-parts list. It accepts CSV, TSV, ordinary XLSX files and pasted tables. Files are processed locally in the browser. Try up to 25 rows per input free, without an account or card; the $29 one-time offline edition supports 20,000 rows and Excel, CSV and readable-report exports for use within one business. It flags changes, missing or short lines and ambiguous data for review. It does not read PDFs, convert units or currencies, select suppliers or place orders.
