Define the customer inside the product
Is the customer an organization with staff and roles or one individual? Does each organization need isolated data? Tenant and authorization decisions shape architecture, testing, and security from the start, not as a cosmetic feature after launch.
Billing is more than a subscription button
Define trials, usage limits, upgrades, failed payments, cancellation, and data export or retention. Collection methods vary by market; verify provider eligibility and terms rather than assuming one.
- Account-owner and team permissions.
- Plan limits and change rules.
- Failed payment, cancellation, and export paths.
Operations and security
The service needs error and performance monitoring, backups, updates, and enough audit history to diagnose customer issues without exposing their data. Specify support and availability commitments in a contract rather than publishing unsupported uptime promises.
Start with a defined user segment
Choose a representative customer and repeated problem. Begin with one operating plan and a core capability people can use or buy. Add complex plan tiers and integrations after observing real usage; premature scale raises build and maintenance costs.
