See the business by category, not just by product
Reports → Products tab → Category Performance rolls the period up by your product categories: units sold, revenue, profit, and margin per category.
Profit uses your cost prices — and for services, the full treatment cost (linked products + labour), so "Advanced Skin Treatments" vs "Waxing" is a real comparison, not a revenue-only one.
A product in multiple categories counts toward its first category so the rows always add up to your actual sales. Items with no category appear as *Uncategorised* — a nudge to tidy the catalog.
💡 Tip: pair it with the Treatment cost card. The more services have real costs, the more honest this table gets.
