Product cost, also called cost of goods or COGS, is the cost of each item you sell.
Set product costs under Costs → Products.
Why you should enter COGS
Venon pulls sales data directly from Shopify and calculates profit automatically.
To show accurate results, Venon needs the real cost of goods for each product.
Where to find it
In the sidebar, open Costs.
Click Products.
The products list
The table shows products with columns for Cost, Price, Type, and the Shipping profile that applies.
Use search to find a product by name.
Click the arrow on a product to expand its variants.
If a product’s variants have different costs, the Cost column shows a range.
Set a product cost in Venon
Click the pencil icon on a product. To edit a single variant, expand the product first and click the pencil on that variant.
Choose a Cost type:
From Shopify: use the Cost per item you already keep in Shopify. Click Sync from Shopify to pull the latest value.
Constant: use a fixed amount per unit, for example 4.20.
% of selling price: calculate cost as a percentage of the selling price or compare price, for example 35%.
Tiered cost: use different per-unit costs depending on quantity, for example 10.00 each for 1–9 units and 8.50 each for 10 or more.
Set Recover product cost on return. Choose whether returned items count as recovered stock, as a loss, or follow the global default.
Click Save Changes.
Update Cost per item in Shopify
Use this if you want Venon to pull product costs from Shopify instead of entering them manually in Venon.
In Shopify, the field is called Cost per item.
After updating Shopify, return to Venon and use Sync from Shopify on the product cost page.
Products without variants
Open Shopify Admin.
Click Products in the left menu.
Select the product you want to update.
Scroll to the Pricing section.
Enter the product’s cost of goods in Cost per item.
Click Save.
Example: if you sell a dog bed for €59.90 and it costs €22.50 from your supplier, enter €22.50 as the Cost per item. Venon can then calculate the true profit per sale from that cost.
Products with variants
Open Shopify Admin and click Products.
Select the product you want to edit.
Click Bulk edit.
Click the … or Columns option in the bulk editor.
Add the Cost per item column.
Enter the cost for each variant, for example Small: €18.50, Medium: €22.50, Large: €28.00.
Click Save.
Sync Shopify costs into Venon
Go back to Venon.
Open Costs → Products.
Find the product or variant you updated.
Choose From Shopify as the cost type if it is not already selected.
Click Sync from Shopify.
Check that the product cost now matches what you entered in Shopify.
Variants
A variant is set to Inherit from product by default, so it uses the product’s cost.
Turn inheritance off when a variant needs its own cost.
If variants have different supplier costs, set the cost at variant level or keep the Shopify Cost per item updated for each variant.
Global defaults
Fallback cost %: if a product has no cost set, Venon uses this percentage of its price. You choose whether it is based on sale price or compare price.
Charge product cost on returns: the account-wide default for whether returned items count as a cost or as recovered stock.
Click Apply Settings to save global defaults.
Costs that change over time
Use the calendar icon when a cost changed on a specific date.
Past orders use the old cost and new orders use the new cost.
A normal edit applies going forward.
Tips
The fastest setup is to keep Cost per item filled in on Shopify and use From Shopify.
Set a sensible Fallback cost % first, so products do not show as 100% profit while you finish entering real costs.
A product with no cost and no fallback is treated as zero cost, which makes profit look too high.
