A production and inventory system for a paint company, built around a Mix Calculator that scales formulas, checks stock before production and records every batch. Live in production.
Paint formulas were calculated by hand for each batch size, which is slow and easy to get wrong. Production sometimes started before anyone confirmed the raw material was in stock, and formulas, a core trade secret, were kept in files anyone could copy.
The client needed a system that made batch calculation exact, protected formulas, and gave a live view of raw material stock.
The heart of the system is the Mix Calculator. Pick a product and a batch size, and it scales the formula to exact quantities, then checks every raw material against current stock before the batch can start.
Formulas are protected: only permitted users can view them, and every access is logged. Raw material stock updates automatically as batches are produced, with alerts when an item runs low.
We added a printable estimate generator for quoting customers, and a complete batch history for quality checks and traceability.
