⚠️
1 bestseller is losing money after ad spend. The Aurora Wall Print tops your sales chart but its true margin is negative once Meta spend is counted. See it in the Sidekick step.
Set true costs — watch the margin turn real
For print-on-demand and dropship items, Shopify's Cost per item is blank, so it reports a fake 100% margin. Set the real landed cost and Marjn recomputes instantly — even where Shopify has nothing.

Connect ad spend (Meta)
Landed cost alone isn't the whole story. Connect your own Meta ad account — read-only, spend totals only — and Marjn subtracts what you actually paid to make each sale. No audiences, no customer data.

Ad spend (Meta)
Not connected
Connect a Meta (Facebook & Instagram) ad account so your margin includes what you spent on ads. Marjn reads spend totals only — no audiences, no customer data.

Ask Sidekick — the payoff
Now the real moment. Ask Shopify Sidekick a margin question the way you already do. Marjn supplies the profit data — so the answer counts landed cost and ad spend, and catches the bestseller quietly losing money.

Guide — formula & questions to ask
Inside the app, the Guide explains exactly how the number is built and gives you copy-paste questions for Sidekick. Here's what merchants see.
Know your true margin
Shopify shows revenue, not profit. Its built-in AI estimates margin but can't see your real landed cost or ad spend — so the number is a guess. Marjn fills that gap and answers your margin questions in Sidekick with real numbers.
How margin is calculated
Gross margin = Revenue − Product cost − Ad spend
Revenue — what your orders actually sold for, read live from Shopify (after discounts).
Product cost — the landed cost per unit you set in Marjn, times units sold — used even when Shopify's cost field is empty.
Ad spend — spend from a connected Meta ad account. Optional; margin still calculates without it.
