Weeks of Supply Replenishment System
Bridge the Supply Chain Gap â Dynamic Velocity-Based Purchase Replenishment in Odoo
Stop relying on static Min/Max reorder points or manual spreadsheet calculations.
Calculate actual weekly sales velocity, set target weeks of stock coverage, and generate vendor-grouped Purchase Orders in one click.
Why Static Min/Max Reorder Rules Fail Modern Supply Chains
Static reorder rules cause overstocking during slow periods and severe stock-outs during demand surges. The Weeks of Supply (WOS) system continuously evaluates actual customer shipments over a configurable look-back window. It dynamically compares current net stock against sales velocity to calculate exact replenishment needsâkeeping your warehouse lean, cash-flow healthy, and fully covered.
Enterprise-Grade Replenishment Automation
A robust data-driven framework ensuring accurate purchasing decisions, complete auditability, and zero manual spreadsheet errors.
Hierarchical WOS Overrides
Configure target coverage weeks and sales history look-back windows at Company default level, with clear override priority: Product > Warehouse > Company.
Real-Time Sales Velocity Engine
Analyzes actual delivered demand from completed done stock moves shipped to customers net of returns, ensuring predictions reflect true consumption.
Audit-Ready Computation Batches
Every calculation run is stored as a Computation Batch with status tracking (Suggested â Confirmed â Ordered / Ignored), giving complete transparency for compliance.
Automated 1-Click PO Creation
Select multiple replenishment suggestions and click to generate draft Purchase Orders, automatically grouped by primary vendor and receiving warehouse.
Weeks of Supply Calculation Logic
Rest easy knowing every purchase suggestion is backed by clear mathematical formulas.
Demand & Inventory Formulas
| Metric | Formula |
|---|---|
| Avg. Weekly Sales | Total Delivered Qty ÷ Look-back Weeks |
| Net Available Qty | OnHand + Incoming â Outgoing (Committed) |
Suggested Order Quantity Logic
| Calculation Step | Formula |
|---|---|
| Raw Requirement | max(0, Target WOS Ã Avg Sales â Net Avail) |
| Final Order Qty | Adjusted for Min Order Qty & Rounding |
Operational Setup Guide
| 1. | Set global defaults in Inventory â Configuration â Settings â Weeks of Supply Replenishment (e.g., 4 Target Weeks, 12 Look-back Weeks). |
| 2. | On product cards, open the Weeks of Supply tab to flag items for inclusion and optionally override product-specific targets. |
| 3. | Run Inventory â Weeks of Supply â Compute Replenishment for selected warehouses or activate the weekly scheduled action. |

User Interface Walkthrough
A clean, standard Odoo UI matching the core inventory and purchase platform themes flawlessly.
Future Development Roadmap
- Integration with seasonal demand weighting algorithms to adjust sales velocity during peak periods.
- Vendor lead-time auto-buffering to automatically extend Target WOS based on supplier reliability.
- Automated inter-warehouse stock transfer suggestions prior to issuing external purchase orders.
