Why ROAS 300% Can Still Mean Losses — Gross Margin in 5 Ecommerce Verticals

"ROAS 300%, so we're profitable." I've seen this line in dozens of internal EC reports — and in maybe half of them, the business was actually losing cash. The trap is gross margin. For a 30%-margin product, ROAS 300% is barely above breakeven. Same ROAS, different margin, opposite conclusion. This...
