Bill8 — the commerce vertical
Bill8 is billing and payments for platforms on Sentin8: merchants, checkout, recurring billing, a double-entry money engine, signed webhooks, fraud screening, and reporting — six Rust services, four Flutter apps, and a unified Rust SDK. Money movement is delegated to Bank8:Payments; bill8 owns the commerce domain.
