Distributors and retailers running ERPNext know the trap: stockouts on your fastest movers while cash sits frozen in slow-moving overstock. ERPNext core gives you a static Reorder Level on each Item and a basic Reorder Report, but those thresholds are hand-typed and go stale the moment demand shifts. There is no native seasonality modelling, no service-level-driven safety stock, and no way to see the replenishment picture across ten warehouses at once. Planners end up exporting Stock Ledger data to spreadsheets every week and guessing — which is exactly where the errors and the tied-up capital come from.

ECOSIRE builds a proper Frappe application (a custom app in your bench with its own module) that closes this gap. We add DocTypes such as Forecast Profile, Demand Forecast, and Replenishment Run that sit alongside your existing Item, Warehouse, and Stock Ledger Entry data. A scheduler event (registered in hooks.py under scheduler_events) periodically pulls consumption history and computes forecasts using exponential smoothing with additive/multiplicative seasonality (Holt-Winters), so each item-warehouse pair gets a demand curve rather than a fixed number. From that curve and your chosen service level, the app derives dynamic safety stock and a rolling reorder point, then compares them against projected available quantity (on-hand less reserved plus incoming).

When a line falls below its dynamic reorder point, the Replenishment Run groups the shortfalls by supplier and warehouse and drafts the right documents — a Material Request for inter-warehouse transfer or a Purchase Order for outside procurement — using ERPNext's standard document APIs so lead times, default suppliers, and UoM conversions all flow through natively. Whitelisted methods (exposed over the Frappe REST API) let planners trigger an ad-hoc run or pull forecast data into dashboards, and a client script adds an approve/adjust step so nothing is auto-submitted without a human unless you want it to be. A what-if simulator lets planners flex growth, seasonality, and lead-time assumptions up to 24 months out and see the resulting order plan before committing. Everything respects ERPNext role profiles and permissions, and is built for Frappe/ERPNext v15 and v16.

Because this is build-to-order, we start with a scoping call to confirm your item classes, warehouse topology, service-level targets, and supplier rules, then build against your exact ERPNext version on a staging bench. Typical delivery is one working week from confirmed scope. You get the full installable source, UAT on staging with a rollback plan, documentation, a training session, and a post-go-live support window — plus the git repository so the app is yours to keep and extend.
