Challenge
Costing lived in scattered spreadsheets, FX swings ate into margins, and multi-level recipes (sub-assembly → set → product) compounded human error every quote.

A multi-tenant SaaS that lets manufacturers compute unlimited-depth BOM costs against live FX in seconds — replacing hours of spreadsheet costing with a single live engine.
Costing lived in scattered spreadsheets, FX swings ate into margins, and multi-level recipes (sub-assembly → set → product) compounded human error every quote.
On Next.js 15 + React 19 + PostgreSQL + Drizzle we built an unlimited-depth BOM engine with cycle detection, wired live TCMB FX and Overhead Allocation (GGP) into one cost engine. Multi-tenant by design with RBAC, audit log, KVKK-compliant company isolation, and PDF/Excel quote export.
Cost owners cut hours of spreadsheet work to seconds; quotes ship to customers as one-click PDF + Excel artifacts.
Strategy if you're early stage, engineering muscle if you're scaling — whatever you need, a 30-minute conversation is enough to start.
