Provider
Avoid unnecessary dependence on a single PSP where volume, risk and operations justify alternatives.
Payment Resilience
Payment redundancy without unnecessary complexity
More providers do not always mean better architecture. Redundancy should solve concrete dependencies.
Payment Method
Combine cards, bank rails, wallets or APMs according to local behavior.
Routing
Define when a transaction should use a different route, where infrastructure supports it.
Settlement
Understand currency, timing, provider and treasury dependencies.
Operations
Design procedures for outages, degradation, reconciliation and escalation.
