Module 01 - Inventory
Stock is not a cell you overwrite. It is a ledger of movements, and the on-hand figure is what that ledger adds up to. That single decision is what stops the number on screen drifting away from the number in the building.
01Catalogue
Set a product up once, then give it as many versions as reality demands, each with its own part number, barcode, price and unit. Size, material and colour describe the difference, so a 50mm cast iron valve and an 80mm one stay one product with two versions rather than two unrelated rows nobody can reconcile.
02Stock and traceability
Stock is held per version, per warehouse, per shelf and per batch. High-value items get their own serial number and carry it through their whole life, so the answer to “which batch did we send them” is a search box rather than an afternoon in the filing cabinet.
03Movements
Goods arriving, goods going out to a job or a customer, goods moving between shelves, and counts corrected after a stocktake. Each one is written down permanently and updates the balance in the same step, so two people can never sell the same last unit.
04Keeping it honest
Cycle counts work through the warehouse a section at a time instead of shutting the year down for a full stocktake. Replenishment rules watch the figures they produce and raise the reorder signal before a shortage reaches the floor.
The delivery is received against its purchase order. Quantities that do not match are recorded as they are, not quietly rounded to the order.
Stock lands on a specific shelf, under a specific batch. Nothing sits in an abstract pool called “warehouse”.
Every issue to a job, transfer between bays and correction after a count adds another line. Nothing is ever overwritten.
The figure on the dashboard is the sum of that history, which is why it cannot silently disagree with the shelf.
Purchasing, sales and manufacturing all resolve their quantities here. One stock truth, not four copies of it drifting apart.
