# Keep stock right

> How stock is counted, reserved and moved between locations.

Stock is counted **per size**. When a customer checks out, the stock for each size they buy is **reserved** so two people cannot buy the last one at the same time. When the order is placed the reservation becomes a sale; if checkout is abandoned, the reservation is released.

## See and adjust stock

Open **Inventory → Stock**. You see every size with its quantity on hand. To correct a count (after a stocktake, a breakage, a delivery), change the number and give a reason. Every change is written to the **movement history**, so you can always see who changed what and why.

## Stock locations (optional)

If you keep stock in more than one place (a shop and a warehouse), turn on **Inventory → Stock Locations**:

-   each location has its own count for every size;
-   **transfers** move stock from one location to another, and both sides of the move are recorded;
-   your site can still show one total, or per-location availability.

## Restock notifications

When a size is out of stock, customers can ask to be told when it is back. See who is waiting under **Inventory → Restock Notifications**.

## Sold

**Inventory → Sold** shows what sold, when, in what quantity, which helps you reorder before you run out.
