How do I add product costs?

Open Products in the sidebar and click a variant. On its page, enter the Unit cost, check From when this cost counts, and click Save in the pill at the top. The unit cost is what you pay your supplier for one piece, without VAT. It is the first cost to set up. A variant without one reads Add its cost in the table.

Each variant has its own page and its own cost. A variant is one version of a product, like size M. A variant's first cost counts from your store's first order day, so every order you have synced gets it. A later price change starts today, or on the day you pick under New cost from. To enter a history, save the oldest cost first, then add each change with the day it started. A cost planned for a later day stays.

If Shopify already holds a cost for a product, nouz copies it for you, and the row says Synced. Once you enter your own, the row says Edited, and a sync never writes over it. The post on historical COGS on Shopify explains why Shopify cannot keep a history of costs. COGS means the cost of the goods you sold.

The same page holds what shipping needs to know: the weight and the packaging size. A missing one is flagged rather than guessed. You can also give the product its own reorder lead time there.

Costs are entered one by one, not imported from a file. If you keep supplier prices in your own spreadsheet, the product cost list template has the columns worth tracking. Variants without a cost come first in the table, and the Unit costs card has a button that lists only those, so you can work down the list.
