Grocery margins are 2-4% net. Card processing fees consume 20-35% of that margin. A 0.3% margin movement is considered a meaningful year for the category. A 1% reduction in payment costs is transformative.

A 45-store Belgian-Dutch chain on €1.4B revenue and €180M card volume pays €1.98M a year in processing alone. Add fraud, chargebacks, terminals, and ops staff: €2.29M, 28% of net profit.

This briefing covers what 30% A2A adoption does to that math: €324K saved in processing, €170K saved in fraud + chargebacks + settlement value + ops efficiency. €494K annually, 3.5-month payback. No reduction in checkout speed once adoption normalises (10 seconds for experienced A2A users vs 8 seconds for card tap).

Full episode for the urban-chain and discount-chain cases, demographic adoption curves, and the staff/customer education playbook.
