What is true profit per order?
The definition
True profit per order is the money left from a single sale after you subtract every cost that order actually carried.
Revenue is what the customer pays you. True profit is what survives after the supplier, the carrier, the platform, the ad account, and the refund log have all taken their share.
It is a per-order number on purpose. Monthly averages can hide money-losing orders inside a store that looks profitable overall — the per-order view is what brings them to the surface.
Why Shopify's revenue isn't your profit
Shopify reports revenue — everything that came in at checkout — but not the costs of generating those sales: supplier invoices, carrier bills, platform fees, ad spend, and refunds. That's why revenue can climb while the money you keep per order shrinks. Revenue measures what came in; true profit measures what survives after the costs of earning it.
The five costs that belong to one order
Five cost items attach to a single order. This is the same set CostPilot Pro uses:
- Cost of goods sold (COGS) — what you pay the supplier for the units in this order.
- Shipping — what the carrier charges you, after subtracting any shipping the buyer paid.
- Platform and payment fees — Shopify's plan cost and the payment-processing charge attributable to this order.
- Ad cost — the ad spend for a period, spread across the orders that period generated.
- Refund cost — money returned to customers, plus the cost of goods that don't come back sellable.
Four of these attach to an order directly. Ad cost is the exception: ad spend buys traffic over a period of time, so it is allocated across that period's orders rather than traced to a single one.
The formula in one line
Put together, the five items give one formula:
Example: an order brings in $30. COGS is $9, shipping nets out at $4 after the buyer-paid portion, platform and payment fees are $2, the allocated share of ad cost is $3, and refund cost is $1. Subtract all five: 30 − 9 − 4 − 2 − 3 − 1 = 11. True profit on the order: $11.
With that number in hand per order, three decisions become straightforward:
- Compare products by what they earn, not by how much they sell.
- Know the discount floor — the price point where true profit hits zero. Below it, each sale costs you money.
- Judge whether an ad channel pays for itself at its current spend.

Rebuilding this calculation by hand every month means re-collecting five cost sources and redoing the arithmetic order by order. CostPilot Pro applies the formula above to the orders in your Shopify store and shows you the per-order result.
