Finished goods & ready items
Once a BOM card is ready, Finished Goods (for product cards) and Ready Items (for component cards) is where you record what you actually made, sell it, or rework it. Both modules work the same way — the difference is just whether the card is marked as a product or an item.
Recording production
Creating a production record reserves the required materials (and any sub-components) from a chosen warehouse and registers the produced quantity, with a production date and optional expiry date.
If there isn't enough of a required material or component available, Masto Control shows exactly which resource is short and by how much before you confirm — including stock sitting on other BOM versions of the same product, in case there's usable stock you forgot about.
Each production run becomes its own batch (lot), with its own cost, so finished-good costing stays as accurate as material costing.
Stock numbers
Same shape as materials: in stock, in products (reserved against pending sales or further production), available, and can produce (how many more units current material stock would support).
A warning threshold can be set per product/item — when available stock drops below it, it's flagged for attention.
Selling
Selling a batch deducts it from stock and links the sale to a sales channel (optional for purely internal tracking). Sales feed directly into analytics.
Rework
If a batch needs to be unmade — defects, a cancelled order, returned stock — Rework lets you return it by component: set a return percentage per composition line (100% by default for all lines) to control how much of each underlying material/component comes back into stock versus is written off as loss.
Production planning
The Planning tab is a calendar of upcoming production plans. For any date, it shows the materials and components required across everything planned, flags shortages (up to 50% short / over 50% short), and lets you drill into the exact resource shortfall before you commit a plan to actual production.
