# Stock Ledger Logs

> Every movement, ever — the record behind every number.

**Stock & Inventory → Stock Ledger Logs** (headed **Immutable Stock Ledger**)
is the audit trail: purchases, sales deductions, adjustments and transfers, in
order.

Columns: Timestamp, Product, Type, Quantity, Unit Cost, Total Cost and
**Reference / Audit Notes**.

## The movement types

| Type | What happened |
| - | - |
| `PURCHASE RECEIVE (+)` | A delivery was checked in |
| `SALE (-)` | Sold at the register |
| `ADJUSTMENT IN (+)` / `ADJUSTMENT OUT (-)` | A manual correction, with its reason |
| `TRANSFER IN (+)` / `TRANSFER OUT (-)` | Moved between your stores |
| `RETURN (+)` | A customer brought something back |
| `DAMAGED (-)` / `EXPIRED (-)` | Written off |

Goods sent back to a supplier appear as a supplier return, which removes stock
and credits the supplier.

## Why nothing here can be edited

Entries are never changed or deleted. Your on-hand quantity is the sum of this
list, so if entries could be rewritten, no number in the product would be
provable. Corrections are new entries.

That is what lets you answer "where did those twelve cases go?" — filter to the
product and read down.

> [!NOTE]
>
> Use this page when a quantity looks wrong. Work backwards from the last
> movement that looked right; the first surprising row is usually the problem —
> often a case booked as one unit, or a delivery counted twice.
