Technical & Commercial Questions
Legacy System Integration FAQs
Answers to the most common questions CTOs and product leads ask when integrating tokenized payments with existing banking, ERP, and accounting systems.
Standard integrations take 2-4 weeks from kickoff to production-ready. This includes connecting to 1-2 core systems (e.g., SAP, Oracle NetSuite, a core banking API). Complex multi-system integrations with custom logic can extend to 6-8 weeks. We provide a detailed project plan with weekly milestones during discovery.
