Costs & rules

Add your product costs

Set what your products cost you so profit is accurate. Missing product costs are the top reason profit looks too high.

Updated June 30, 2026

Product cost is the largest number in your profit, so this is the first thing to set up. If a product has no cost, the app treats its margin as if the goods were free, which makes profit look much higher than it really is.

Steps

  1. Open Cost rules, then Product costs (/app/costs/product-costs).
  2. For each product, enter what it costs you per unit. If you already keep a cost per item in Shopify, that value is used automatically.
  3. To do many at once, import a spreadsheet (CSV) of your costs instead of typing each one.
  4. Save your changes.

What you should see

Once costs are saved, the app recalculates your orders and your profit numbers drop to a realistic level. The Data quality page will show higher cost coverage, and products that were missing a cost will no longer be flagged.

Tip

If most of your range shares a pattern (for example a vendor or a product type with a known markup), you can set a cost rule that fills the cost for all matching products at once, instead of entering them one by one.
