Measure the real impact of your promo codes
Analyze the performance of each coupon and discount to optimize your promotional strategy and protect your margins.
Promotions without tracking eat into your margins
Unknown ROI
A promo code generating 20,000€ of revenue in a month can still show a sharply negative ROI: of the 400 redemptions, 70% would have bought at full price. Without incremental measurement (vs a control), you pour budget into promos that destroy margin.
Coupon abuse
A "WELCOME10" code meant to be used once per customer ends up redeemed 8 to 15 times by the 5% savviest users (multi-accounts, email +1 aliases). Without automated detection, that's 4 to 7% of promo revenue lost to abuse on average.
Sales cannibalization
Your promos cannibalize full-price sales: a regular customer only buys during promo windows. Over 6 months, a mid-size merchant loses 8 to 14% of net margin to poorly calibrated promotions, often without noticing.
Fullmetrix analyzes each coupon in depth
ROI per coupon
Incremental calculation per coupon: revenue generated minus revenue customers would have driven without the promo (estimated via control segment or matched cohort). Each code lands with its true ROI: positive if incremental margin > discount cost, negative otherwise.
Usage tracking
Per code: redemption count, average discount amount, AOV with coupon, new vs returning customers, most active RFM segments. Exportable for follow-up or post-campaign analysis in 2 clicks.
Margin impact
Margin erosion view by category, period and product: a -20% applied to your "Accessories" category (45% margin) doesn't land like a -20% on "Electronics" (12% margin) — the second one destroys profitability.
