A product
A variant
The product’s Variants tab lists its variants with their price, how many an order may hold and what they send, and their stock at the right of each row. Edit opens a variant in two parts: Price and Stock, and Delivery, which is what it sends and what it asks the buyer. Drag a row to change the order buyers see them in.
Stock
Each variant says how its stock is counted, under Stock in its Price and Stock, with how many there are beside it under In Stock.
A variant that counts its stock does not sell more than it has. A cart that asks for more is turned away, and a payment that arrives for more than is left is not completed until you add stock and mark the order paid, or refund it.
The store alerts you when a variant runs low. The number that counts as low is in the store’s settings. A variant that counts its keys and has never had one is not reported: nothing has run out.
Nothing ever returns to stock. A key that was delivered belongs to its order, even when that order is refunded, and a key replaced by delivering an order again is revoked. A number you set does not go back up either: raise it yourself.
