What writes to the ledger
Know every way a quantity changes, so a movement you did not type never surprises you.
Updated 10 November 2026
- Why
- One ledger is only one truth if every part writes to it the same way.
- How
- Read the table below, then find any movement in
/app/stock?view=movementsby its kind and reference.
The writers today
| What happens | What is written |
|---|---|
| A person records a movement from a line's drawer | An adjustment, a transfer, a write off, a return or a receipt, each with its reason. |
| A count is closed | One adjustment per line whose counted figure differs from the ledger. |
| A sales order is confirmed | A reservation per catalogue product line, at the default location. Cancelling releases it and reopening reserves it again. |
| A sales order is fulfilled | An issue per product line. Where less is on hand than was ordered, the ledger issues what it holds and the workspace is told. |
| An order carries a designed shank PCD tool | A reservation of the bars and discs its take off names from your own counted stock, a release if the order is cancelled or the line changes and a consumption when the order is fulfilled. |
| A quote for a solid round tool becomes an order | A reservation of the blanks cut from each tray. See rods and trays. |
| A paid website order holds a blade stocked by length | An issue of the length times the quantity, in millimetres, from that blade's coil. |
| A blade's stock is counted in Catalogue | An opening the first time, an adjustment after that. |
| Goods in is posted against a purchase order | A receipt per line, carrying its landed unit cost. Goods in belongs to Source. |
| A system posts a movement through the API | One movement, marked Integration. See the API. |
What never fails for stock
- A reservation never fails an order. A product the ledger has never seen gets a line at zero and is reserved against, so reserved can exceed on hand: that is a back order.
- A paid website order always stands. If the coil holds less than the order takes, the ledger issues what is there and the workspace is told how much more was sold than held.
- A repeat of the same website order line or designed line writes nothing twice.
Blades stocked by length
A Commerce store can stock a coil cut blade in millimetres on the same ledger. A blade is either always restocked, where the balance is for the team to watch and never limits a sale. Or it is sold until it runs out, where it leaves the store once less than its shortest length is left. The store itself never shows a balance.
Among the PCD design modules, only the shank tool reserves and consumes on the ledger today. The saw blade and the profile cutter read their stock rows to price a design and reserve nothing.
