Ecommerce teams often use ROAS because it is visible and easy to compare. The risk is treating it as profit. A stronger system connects ad-platform ROAS with order economics and backend revenue.
Start with AOV and contribution
AOV tells you revenue per order. Contribution margin tells you how much remains after variable costs. Together they define the acquisition budget.
Model returns
A storewide return rate can hide product differences. If returns are material, include them before scaling campaigns aggressively.
Separate platform ROAS from blended performance
Meta and Google attribute conversions using different rules. Use platform ROAS for optimization and backend revenue for overall business reporting.
Distinguish prospecting from retention
Retargeting and branded search often report stronger ROAS because they capture existing demand. Prospecting may show lower immediate ROAS while finding new customers.
Track contribution profit
Pair spend and attributed revenue with estimated contribution profit. This reveals campaigns that generate sales but destroy margin.
Calculate your own break-even point
Use your real product costs, fees, returns and conversion rate instead of relying on generic targets.
