Inventory Management
Understand stock balances, the movement ledger, adjustments, consumption, wastage, returns, and how they affect reports.
Use this when: You want to know how much stock you have on hand and track every movement in and out.
Inventory is ledger-backed. Your current balance is the running total of every recorded movement — stock in, issue, consumption, wastage, return, and adjustment — so the numbers are always explainable.
How Stock Is Tracked
Every stock change is recorded as a movement. Your current balance is simply the sum of those movements, which means you can always trace why a number is what it is.
The system prevents stock from going negative and guards against the same delivery, issue, or report being counted twice.
| Movement | Meaning | Usual source |
|---|---|---|
| Stock in | Material added to stock | Verified delivery |
| Material issue | Stock issued to a project or site | Approved requisition |
| Consumption | Material used on site | Consumption log or approved daily report |
| Wastage | Lost, damaged, or unusable stock | Consumption log with a wastage reason |
| Return | Unused stock returned | Site return entry |
| Adjustment | Controlled manual correction | Store or admin adjustment |
Movements to Balance
Inbound movements raise the balance, outbound movements lower it, and the balance feeds reports and low-stock alerts.
Operating Rules
Treat manual adjustments as exceptional, and always write a clear, specific reason.
Verify deliveries only after received quantity and condition are checked.
Use requisitions and issues when moving stock from the store to a site.
Use consumption logs to record actual usage, wastage, and returns.
Review low-stock and consumption reports before re-ordering.
