Attribution ROAS vs Blended MER Divergence
Ad platform reporting (Meta 7-day click, Google Ads) often double-counts touchpoints. Always reconcile channel ROAS with total blended Marketing Efficiency Ratio (Total Store Revenue ÷ Blended Spend) to detect platform inflation.
Cash Float & Return Lag Volatility
Customer return rates (3%–15%) create cash-flow latency where credit card chargebacks and reverse logistics costs hit weeks after ad invoices clear. Maintain working capital reserves during Q4 ad spend spikes.
Marginal ROAS & Diminishing Returns
Scaling ad budgets inevitably suffers audience saturation. The marginal ROAS on incremental spend drops before blended ROAS collapses. Use break-even targets as a firm risk boundary.
