GRAINSIFT
Check factory cost sheets line by line, from both sides
Factory costing still runs on emailed Excel sheets. Lines don't add up, the reason behind each price is unclear, and every round restarts from "too expensive." GRAINSIFT puts brand and factory on the same sheet: any format, checked line by line, math first, then every negotiation round tracked until both sides land on one final number. Neutral by design: brand margins stay private, factories submit free. Team admins see approvals, activity and margin across the line.
Hi Product Hunt — this is the GRAINSIFT team.
Brands and factories negotiate over cost sheets every season. The brand says "too expensive," the factory shaves a few cents, and nobody can say which line was off — often because the sheet itself doesn't add up.
GRAINSIFT checks every line first: line amount vs price × consumption, totals vs lines, numbers typed as text, mixed units, duplicated lines, outlier prices. Until the numbers add up, there's no verdict. Fix a cell on screen and re-check; the original stays.
Then brands see the gap to their target FOB and their walk-away price — brand-only numbers the factory never sees. Factories check quotes before sending and submit to brands for free. It works next to your PLM or ERP.
Free to start. No sheet handy? There's a sample verdict. Or try it on a quote you've already closed and see if it finds the lines you pushed back on.
We'd love one honest piece of feedback: where did it get your sheet wrong?
