Why Modern Payment Architecture?
Payment friction directly drains revenue. Clunky checkouts cause buyers to abandon transactions, rigid billing logic prevents you from launching new pricing experiments, and failed card renewals lead to silent churn. Engineered payment integrations give you complete flexibility over subscription models, local payment methods, and automated reconciliation while offloading PCI compliance.
