Most stores look at revenue and the ROAS in their ads dashboard and think they know how they're doing. The problem is that neither number tells you the only thing that matters: how much money your business actually keeps at the end of the day.
The net profit formula
Your real net profit starts from your sales and subtracts, one by one, every real cash outflow. It's not an estimate — it's what hits the bank.
- Revenue (gross sales collected)
- − Refunds and cancellations
- − COGS (cost of goods)
- − Real shipping
- − Gateway fees (Stripe, Shopify Payments…)
- − Ad spend (Meta, TikTok)
- = Net profit
If you don't subtract every cost in the same place, you're not measuring profit — you're decorating revenue.
Why do it every day
Margin moves with every product change, shipping country and campaign. Checking it once a month, in a spreadsheet you reconcile by hand, is too late to cut what loses and scale what wins. Seeing it every day turns margin into a lever, not a report.
That's exactly what ProfitFly does: it crosses Shopify with Meta and TikTok and gives you your real net profit — without touching a spreadsheet.
