Key Difference

Revenue is money coming in. Profit is money left over after paying all bills, suppliers, shipping carriers, and marketing costs.

A store generating $1,000,000 in revenue with $1,100,000 in expenses is operating at a $100,000 loss.

Developer Takeaway

ROAS vs. POAS: In ad campaign tracking, optimize for Return on Ad Spend (ROAS based on revenue) or Profit on Ad Spend (POAS based on profit margin) to prevent spending more on ads than a product's net profit margin.
