Eight Production-Ready SaaS Foundations
Everything your SaaS product needs to sign enterprise contracts, bill customers recurringly, and scale reliably.

Stripe and Paddle customer portal integration with recurring plans, metered usage billing, prorations, tax compliance, and automated dunning.
Granular RBAC & Team Permissions
Role-based access control with granular team invitations, workspace management, and SSO (Google, Microsoft, SAML/Okta).
Customer Onboarding Workflows
Guided step-by-step product walkthroughs, demo dataset seeding, and self-service configuration to maximize day-one activation.
Webhooks & Outbound Integrations
Idempotent event webhooks, Zapier/Make endpoints, and developer API keys allowing your customers to integrate with their tools.
Audit Logging & Security Trail
Tamper-evident activity histories tracking critical actions, permission changes, exports, and compliance-ready data access.
