Stock tracking

Salesmaster tracks stock quantities so you know when to reorder and can reconcile inventory with sales.

This page explains how stock is recorded, what a "stock receipt" is, how stock is consumed, and the rules for editing or deleting stock records.

When inventory tracking is enabled, every completed Sale will create a stock-used history entry for the item(s) sold. The system records how many units were used (the quantity entered on the Sale screen) and reduces on-hand quantity accordingly. This per-sale stock usage is what the Manage Stock screen and reports use to compute remaining stock and COGS.
Stock consumption follows FIFO (first-in, first-out): older stock receipts are consumed first when computing which received units were used by a Sale. See the "stock receipt" and "Edit stock entries" sections for details on how this affects edits and deletions.

Inventory tracking must be turned on per item. Open the item (Add or Edit) and enable the "Stock tracking" (or "Track inventory") option.
If tracking is disabled for an item, selling that item will not decrement stock.

Open Catalog > List Items and select the item you want to add stock for.
From the item menu choose Manage Stock and click Add Stock.
Fill the add-stock form:
- Quantity — how many units you received.
- Cost per unit — optional; useful for valuation and reports.
- Supplier — optional; select Supplier for the stock receipt.
- Notes — optional (delivery or invoice reference).
Save/Add Stock. The system creates a new stock receipt and increases the on-hand quantity immediately. The receipt is recorded in stock history.

In the Manage Stock screen you'll see individual stock receipt entries. You can edit the quantity or cost for stock receipts to increase or decrease it.
When you edit a receipt entry, the app will show the remaining quantity available (original received minus units already sold), and you can only reduce unused quantities yet.

Stock receipt entries can typically only be deleted if none of the received units have been used in a sale. If any units from that receipt were sold, deletion is usually blocked to preserve transaction history.
If deletion is blocked, consider creating a negative adjustment (remove quantity) for the stock receipt.
