Building a SaaS Product: What Developers Often Underestimate

Building a SaaS product involves much more than implementing its core features. Teams must also consider authentication, authorization, billing, data ownership, and operational reliability.

The Hidden Infrastructure

Account management, background jobs, payment webhooks, usage tracking, and error monitoring can become essential parts of a production application.

Plan for Failure

External APIs can fail, payments can be delayed, and background jobs can run more than once. Systems should handle retries and unexpected conditions safely.

Start Simple, but Design Carefully

Avoid premature complexity while maintaining clear boundaries between application components. Good engineering makes future changes easier without overbuilding the initial product.
