Managing complex Bills of Materials, stock levels, and purchase dates across multiple Excel tabs leads to broken formulas, unexpected stock outs, and costly delays.
ProdCalc is the lightweight MRP built for small-to-medium manufacturers, machine shops, and fabricators. Replace chaotic formulas with an automated shortage engine—no massive setup required.
Designed for How You Actually Build Things
Unlike rigid legacy ERPs or static spreadsheets, ProdCalc natively understands every stage of your inventory pipeline.
| Material Type | What It Does | Why Spreadsheets Struggle | The ProdCalc Solution |
|---|---|---|---|
| Raw Materials | Bulk inputs purchased from vendors (wood slabs, steel coils, screws, glue). | Tracking lead times and vendor quantities across separate tabs breaks easily. | Centralized inventory tracking with real-time stock level alerts. |
| Fractionated Materials | Bulk stock cut or split into equal production parts (e.g., wood slab cut into strips). | Calculating yield ratios and off-cuts requires complex custom formulas. | Native fractionated logic automatically calculates child parts from parent stock. |
| Assembled Materials | Intermediary assemblies or finished goods ready for customer shipping. | Multi-level exploding BOMs slow down Excel and cause sync errors. | Dynamic multi-level BOM exploding that updates component needs instantly. |
How ProdCalc Eliminates Production Friction
- Automated Shortage Engine: Create an Output Forecast for a customer order, and ProdCalc instantly scans stock to highlight exact shortage dates for every raw, fractionated, and assembled part.
- Dynamic Input & Output Forecasts: Model demand changes and incoming supplier shipments before committing to purchase orders or shop floor runs.
- Batch Traceability: Move beyond single-cell inventory totals. Track individual material batches from receipt through production execution.
See Your Shortages in 2 Minutes
Don’t worry about uploading messy Excel sheets. Test the engine right now with a single product line:
1. Enter 1 Finished Assembly (e.g., Wood Chair)
2. Add 2–3 Components (e.g., Wood Slab, Screws)
3. Set your delivery date to view your shortage breakdown.
