Incrementality, not vanity
Every "members spend more" claim is selection bias — your best customers join loyalty anyway. Buya withholds a random holdout from day one, so the gap between exposed and held-back is a causal number. We report ISS (incremental same-store sales) and iROAS — proven extra sales per rand of loyalty cost — per campaign, so you kill what doesn't pay and double the winners.
Neutral & cross-POS
One customer resolved across Yoco, GAAP and SumUp. You're never locked to a till vendor, and switching POS never orphans your customer graph.
Anti-aggregator
No fat commission on orders — that's the model Buya is built against. A flat subscription, your customers, your margin. The aggregator rents you your own regulars.
The consumer graph
One portable Buya identity across every place a customer returns to — with explicit, POPIA-first consent. A cross-merchant view no single-shop loyalty app can build.
A concierge that removes the decision
Like Checkers' Pixie, but on a cross-merchant graph and incrementality-native. Your own named assistant learns each regular's usual, reads the occasion — Soweto derby, Saturday 20:45 — and lines up the order for a one-tap yes. Every nudge is measured against the holdout, so you know it caused the sale.
"Your usual Mogodu + a Castle, lined up for the derby?" — Naledi
