What is SaaS development?

SaaS development is designing and building software that customers use online and pay for by subscription. Alongside the product itself, it covers the parts every SaaS needs: sign-up and login, separate workspaces for each customer, plans and billing, onboarding, an admin console and analytics. Most products start with a focused first version, then grow in regular releases based on how customers use them.

What does a SaaS cost?

It depends on how much the first version needs to do, how many user roles and integrations it has and how billing works. A focused MVP is a much smaller project than a full platform, so we usually price the first release, then plan later releases as you learn from customers.
