How to build a SaaS
Follow these steps in Evonx to a multi-tenant SaaS codebase with organizations, roles, and billing integration hooks.
Step-by-step
Choose tenant model
Decide organization-scoped data and which roles can invite members.
Scaffold auth and orgs
Prompt for signup, organization creation, invites, and role guards on routes.
Add product surface
Define the primary job-to-be-done screens beyond auth—dashboards, settings, or core workflow.
Plan billing
Add Stripe customer and subscription placeholders; map plan tiers to feature flags.
Harden operations
Request audit logs, admin impersonation safeguards, and environment-based config.
Ship iteratively
Use evolution threads for features; keep main branch deployable with previews per change.
Outcome
A multi-tenant SaaS codebase with organizations, roles, and billing integration hooks.

FAQ
What breaks first in early SaaS builds?
Tenant isolation and billing edge cases. This guide forces organization, membership, and subscription decisions before feature sprawl.
Should I add Stripe before or after auth?
Auth and tenant context first, then Stripe customers/subscriptions mapped to organizations—see the Stripe subscriptions guide for webhook detail.
Is the SaaS template required?
No, but it encodes the entity model this guide describes so Evonx can generate consistent screens faster.
