Written and reviewed by Seller Profit Guard Editorial Team.

An invented closed Shopify cohort retains USD 6,400 across 80 paid orders. After USD 5,000 of product, payment, attributable acquisition, fulfillment, mature return, plan and app, support, and other costs, contribution is USD 1,400, margin is 21.88%, and contribution per retained order is USD 17.50.

Open paid-store fixture

An invented closed Shopify cohort retains USD 6,400 across 80 paid orders. After USD 5,000 of product, payment, attributable acquisition, fulfillment, mature return, plan and app, support, and other costs, contribution is USD 1,400, margin is 21.88%, and contribution per retained order is USD 17.50. Use a materially different paid owned-store cohort rather than renaming the organic marketplace example. Checkpoint 1 in the paid owned-store worksheet records channel, product scope, currency, cohort dates, settlement cutoff, return maturity, source version, owner, reviewer, and accepted formula before interpretation.

For open paid-store fixture, preserve payment fees, paid acquisition, plan and app allocation, owned-store support labor, fulfillment, returns, product cost, and exclusions rather than calling the channel fee-free.

Paid Owned-Store Contribution Example: evidence exercise 1

Reperform open paid-store fixture with invented organic marketplace and paid owned-store cohorts. Hold currency, closed dates, retained-revenue definition, retained-order definition, settlement cutoff, return maturity, product scope, cost rules, and evidence controls constant where comparison requires them.

Archive the accepted packet before varying the field. Explain the resulting total channel cost, total contribution, contribution margin, revenue per retained order, cost per retained order, contribution per retained order, A-minus-B difference, decision, monitoring trigger, and restoration path.

Reperform the paid Shopify fixture

The invented Shopify cohort contains 80 mature retained paid orders and USD 6,400 retained net revenue. It carries USD 2,400 product cost, USD 250 payment and platform fees, USD 500 attributable acquisition, USD 720 fulfillment, USD 400 mature return loss, USD 300 software and fixed cost, USD 320 support labor, and USD 110 other cost.

Total declared cost is USD 5,000, leaving USD 1,400 contribution. Margin is 21.88%, and contribution per retained order is USD 17.50. These values are conditional on the paid-order attribution bridge, plan and app allocation, and mature retained-order denominator.

The example does not prove that Etsy outperforms Shopify. The two observed packets differ in volume, acquisition mix, support burden, cost allocation, and possibly product or customer mix; those differences require separate controls before causal language.

Use Shopify reports without treating gross profit as full contribution

Shopify profit reports depend on cost per item recorded at the time of sale. Discounts and refunds affect net sales and reported margin, and missing product cost can omit orders from profit analysis. Preserve cost-version completeness before relying on platform gross profit.

Channel contribution extends beyond Shopify gross profit by adding payment, acquisition, fulfillment, return severity, plan and app allocation, support labor, and other declared costs at the same retained-order grain. Reconcile those lines to bills, campaign evidence, invoices, and time records.

If historical cost per item is incomplete or static while actual costs changed, use a seller ledger with versioned evidence and record the discrepancy instead of forcing the platform report to appear complete.
