Why Your Agency’s ROAS Screenshot Means Nothing
By Ashish Rai, CEO, Purple Circle · September 2026 · 6 min read
Your agency sent you a ROAS screenshot. 4.2x. Maybe 5x. It looks great. You reshared it. They got paid. And your bank balance didn’t move. That screenshot is the most expensive lie in ecommerce — not because your agency is dishonest, but because platform ROAS was never designed to tell you if your business is making money.
Meta says: 4.2x ROAS
Google says: 3.8x ROAS
Your bank says: Where’s the money?
Three numbers. Three different stories. Only one is real.
What your agency’s ROAS actually measures
Platform ROAS = revenue the platform believes it caused ÷ ad spend. Here’s everything it ignores:
Returns and RTO
Revenue counted day 1. Refund day 14. ROAS never updates.
Product Cost
COGS, shipping, packaging — invisible to the platform.
Double Counting
Meta and Google both claim the same sale.
Discounts and Fees
Gateway, GST, coupons — all subtracted after ROAS.
We’ve broken this down with a real case study: how a store with great ROAS was still losing money every month.
The ROAS vs reality gap
| What you’re told | What actually happened |
|---|---|
| Meta ROAS: 4.2x | Calculated on gross revenue, before 22% returned |
| Google ROAS: 3.8x | Claimed 40% of the same sales Meta claimed |
| “Blended ROAS: 4.0x” | Just averaged the inflated numbers |
| Agency: “Great month!” | Real MER was 1.9x. Net margin was 4%. |
The gap between platform ROAS and real MER is where your money disappears.
The agency incentive problem
Your ad spend goes
UP
Agency fee goes
UP
Your profit goes
DOWN
When your agency makes more money the more you spend, they will never tell you to stop.
5 signs your agency is costing you money
1. They’ve never asked for your margins. If your agency doesn’t know your COGS, shipping cost, and return rate, they’re optimizing blind.
2. They celebrate revenue, not profit. Your brand can sell Rs.15L and keep only Rs.80k.
3. They scale spend without knowing your breakeven. Your breakeven ROAS is the minimum return to not lose money.
4. They show platform ROAS, never MER. MER can’t be gamed by attribution. If they only show platform ROAS, they’re showing the number that makes them look best.
5. They bill on % of ad spend. More spend = more fee. The incentive is structurally broken.
Why switching agencies doesn’t fix it
You’ve switched agencies twice. Maybe three times. ROAS looked great every time. You’re still not profitable. Every agency solved the wrong problem. You gave them a ROAS target. Nobody gave them a profit target. Nobody asked: what’s the CAC payback period? What’s the margin after returns and RTO?
How Purple Circle is built differently
TYPICAL AGENCY
| Reports | Platform ROAS |
| Goal | Maximize revenue |

| Knows breakeven? | No |
| Tracks returns? | No |
| Billing | % of ad spend |
| Incentive | Spend more |

PURPLE CIRCLE
| Reports | MER + contribution margin |
| Goal | Maximize profit |
| Knows margins? | First thing we ask |
| Knows breakeven? | We calculate it |
| Tracks returns? | Adjusted weekly |
| Billing | Performance-based |
| Incentive | Profit more |
| Will tell you to stop? | Yes — we have |
We don’t start with ad campaigns. We start with your P&L. Before we touch your ad account, we know your COGS, shipping cost, return rate by SKU, real breakeven ROAS, and CAC payback period. If unit economics are broken, we tell you — and help fix them before scaling.
We’ve walked away from clients whose margins couldn’t support paid acquisition. We’ve told brands to reduce ad spend because they were scaling losses. No agency whose revenue depends on your ad spend will ever do that.
What we check before spending a single rupee
STEP 1
Unit Economics
COGS, margin, breakeven
STEP 2
RTO and Returns
Rate by SKU, real cost
STEP 3
CAC Payback
How fast cash returns
STEP 4
Real MER
Not platform ROAS
THEN
Scale Ads
Only when math works
The takeaway
Next time your agency sends a ROAS screenshot, ask one question: What was our MER last month, and what’s our contribution margin after returns? If they can’t answer, they’re managing your ad account. They’re not managing your business.
Stop paying for ROAS screenshots.
Start paying for profit.

FAQ
Why is ROAS misleading?
Platform ROAS measures gross revenue attributed by the ad platform. It ignores returns, costs, fees, and double-counts across channels. A 4x ROAS can easily be a loss-making campaign.
What should I track instead of ROAS?
MER (total revenue divided by total ad spend across all channels) and contribution margin after returns.
How do I know if my agency is wasting money?
If they never asked for your margins, don’t know your breakeven ROAS, celebrate revenue not profit, and bill on % of ad spend.
What makes Purple Circle different?
We start with your P&L, calculate breakeven ROAS, track MER and contribution margin weekly, use performance-based billing, and will tell you to stop scaling if your economics don’t support it.
