SaaSCore — Enterprise SaaS Foundation

A seed-funded startup had a great product and a €180k/year enterprise deal on hold — pending SSO and audit logs their engineers had been rebuilding for four months. We shipped the full SaaS layer in 10 weeks.

The Challenge

60% of engineering budget spent on infrastructure. Stripe webhooks missing events. Enterprise prospects blocked on SSO, RBAC, and audit log requirements.

The Solution

Stripe Billing with seat-based tiers, Google and Microsoft SSO via NextAuth, team invites, granular RBAC, tamper-evident audit logs, and a self-serve upgrade flow — plus a Redis retry queue that fixed the missed webhooks.
