Stock and stock management
How to switch on stock management for an item, enter the quantity on hand, and what happens to stock when you sell at the till and in the webshop.
Cmerce can keep track of how many of each item you have left. You switch on stock management per variant. Items without stock management – for example services and digital goods – can always be sold, and the till shows no stock status for them.
Before you start
- You need permission to manage products.
- If the item is synchronised from Shopify, stock is managed in Shopify. See «Shopify» below.
How to do it
- Go to «Katalog» (Catalogue) → «Produkter» (Products) and open the item.
- Open the «Varianter» (Variants) tab and open the variant.
- Under «Lagerstyring» (Stock management), switch on «Lagerstyrt» (Stock managed).
- Fill in «Lagerbeholdning» (Stock on hand) – the number you have in stock now.
- Save.
If the item has several variants, do the same for each variant. The «Lager» (Stock) column in the variant list shows the quantity, or «Ubegrenset» (Unlimited) when the variant is not stock-managed.

Counting and adjusting
When you have counted the items, open the variant and enter the correct number in «Lagerbeholdning».
How stock changes automatically
| Event | What happens to stock |
|---|---|
| Sale at the till | Deducted |
| Return at the till | Added back |
| Order in the webshop | Deducted when the order is placed |
Only stock-managed variants change. Gift cards, bookings, punch cards and subscriptions have no stock.
The till and the webshop
- At the till you see the quantity in stock on each stock-managed item. If the item is out of stock or below zero, the number is shown in red.
- Selling an out-of-stock item at the till: The till does not stop you – the customer is holding the item, after all. You get the message «Utsolgt» (Sold out) and choose «Selg likevel» (Sell anyway) or «Avbryt» (Cancel). If you sell anyway, stock goes negative. A negative number means the count is wrong and should be corrected.
- In the webshop the customer cannot buy more of a stock-managed variant than you have in stock.
- In search in the webshop and at the till, items in stock are shown ahead of sold-out items when the matches are otherwise equally good.
Shopify
If your shop is connected to Shopify, Shopify is the master source for stock:
- The quantity is fetched from Shopify and cannot be changed here. Stock is the sum of the Shopify locations you have chosen in the Shopify settings.
- Sales at the till are deducted automatically from Shopify stock, at the location you have chosen for write-back.
- Changes you make in Shopify come across to Cmerce automatically.

Good to know
- Stock is one number per variant. Cmerce does not keep separate stock figures per shop or location.
- If you switch off «Lagerstyrt», the variant can be sold without limit, and stock status is no longer shown.
- Stock changes from sales and returns are documented by the sale and the return themselves.
Frequently asked questions
Why is stock negative?
Someone sold the item at the till after stock showed 0. Count the item and enter the correct number.
The customer can't buy the item in the webshop, but I have it in stock.
Check «Lagerbeholdning» on the right variant. If the item is from Shopify, check the stock in Shopify and which locations are counted.
