Inside this topic for Interior Designers & Modular Home

Step 01
Reason 1: Reported ROAS includes view-through
Meta credits revenue to ads viewed but not clicked, sometimes up to 7 days. Strip view-through; click-only ROAS is typically 25–40% lower.
Step 02
Reason 2: Hidden CAC components
Agency retainer, creative production, tooling (Klaviyo, Triple Whale, Shopify apps), influencer payments. Add 15–25% to media-only CAC.
Step 03
Reason 3: COD return adjustment
If 40% of orders are COD with 18% return rate, effective CAC is 7.2% higher than reported. India D2C brands miss this routinely.
Step 04
Reason 4: Cohort drift
Each new cohort might have lower LTV than the last while CAC rises. Blended CAC hides this for 6+ months. Track cohort-level monthly.
Step 05
Reason 5: Brand-search cannibalisation
Branded-search ads convert at 8x+ ROAS but cannibalise organic clicks. Subtract organic-equivalent revenue to get true incremental CAC.

FAQ

Frequently asked questions

How do I know if my CAC is actually rising or just measured better?

If you've changed measurement methodology, run both old and new methods in parallel for 60 days. Otherwise, lock methodology and trust the trend, not absolute numbers month-over-month.

Interior Designers & Modular Home carries category-specific constraints — junk leads, long project cycles. Average CPC for Interior Design: 30–250 ₹; typical CAC: 1,500–18,000 ₹. Apply the playbook above with these unit-economics constraints in mind: meta-ads, seo-services, google-ads are the highest-leverage channels for Interior Design.

What's the strongest counter-argument?

Listed in the counter-arguments section above. The single strongest case-by-case counter is base rates — the argument may hold 70% of the time but your specific situation may be in the 30%.

Where does the reasoning fail?

In categories with idiosyncratic dynamics (regulatory novelty, capital-intensive product, very long buying cycles). Adapt the reasoning to the local constraints before applying.

Is this opinion or fact?

Both. The framework is opinion (an operator viewpoint, weighted by Frameleads engagements). The supporting numbers are facts (taxonomy + public-domain benchmarks). The recommendation is opinion built on facts.
