ROAS is easy to screenshot. It is also easy to hide behind. Plenty of brands post a tidy return figure in Slack while the founder still cannot sleep.
That gap is not mysterious. ROAS ignores a lot of the real business.
What ROAS quietly skips
- Discounting that bought the conversion
- Returns and refunds that land later
- Stockouts that stop the next order
- Creative and agency fees outside the ad platform
- Whether new customers actually come back
You can “hit target” and still burn cash. You can miss a vanity ROAS and still be fine if contribution margin is honest and inventory turns cleanly.
Better companion metrics
Pick two or three that match how you get paid:
- Contribution after discounts and estimated returns
- New customer share (if growth is the goal)
- Cover days on advertised SKUs
- Refund rate by channel when you can see it
None of these need a PhD stack. They need a weekly habit.
A practical weekly check
- Top spend campaigns: ROAS plus refund chatter plus stock on the main SKUs.
- Anything scaled hard in the last fortnight: did cover days collapse?
- Anything “efficient” with ugly reviews or CS load: kill the romantic story.
If your tools only celebrate efficiency, you will optimise into a corner. Operators need the unglamorous view. More on the multi-channel mess in ads software for Shopify.
A story you already know
Channel looks efficient. Finance asks where the cash went. Half of it was discounts, a quarter returns, and the rest sat in ads that sold through inventory you cannot replace this month. The ROAS screenshot was not lying. It was incomplete.
Questions people actually ask
Is MER better than ROAS?
Healthier for whole P&L. Use ROAS for channel craft; use broader efficiency for “are we okay?”
Ignore ROAS completely?
No. Stop treating it as the only adult in the room.
Three screenshots that lie in different ways
- High ROAS, high discount rate: you bought revenue with margin.
- High ROAS, collapsing cover: you bought a stockout.
- High ROAS, rising refunds: you bought a customer service problem.
Train your team to ask “which of these three?” before celebrating. It sounds pedantic. It saves arguments with finance.
Talk to finance in their language
Bring contribution estimates and refund rates to the conversation, not only platform screenshots. You will get better decisions and fewer “why is cash tight?” surprises two weeks later.
