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.
