A financial system of record for the field - where the cash is collected, the deliveries are made, and the money has always been hardest to see.
Distribution CRM
Data Science - Forecasting
A national retailer was forecasting in spreadsheets and paying for it twice: stockouts on the fast movers, working capital buried in the slow ones. Welzin shipped a forecasting system that feeds replenishment directly - backtested, monitored, and owned to the metric.
