How this calculator works

The calculator compares initial build/setup, incremental integrations, maintenance effort, platform and license fees, and an estimated incident cost over your chosen horizon. It then combines the financial result with strategic drivers (compliance, latency, mapping complexity, team capacity, speed to market and connector coverage) into a leaning — custom, iPaaS or hybrid.
