The short version
$80,000 to $500,000
A well-scoped SaaS MVP with core features, subscription billing, and user management starts around $80K to $130K. Most commercial SaaS products land in the $130K to $250K range. Enterprise SaaS with complex workflows, security requirements, and integrations pushes $300K to $500K+. The wide range reflects how dramatically SaaS products vary in scope.
A SaaS product is not just an app. It is a continuously running business with recurring billing, user management, onboarding flows, analytics, integrations, and an architecture that needs to scale as you add customers.
The unique cost components of a SaaS build include:
Most SaaS founders overbuild v1. They spend 12 months and $300K building features that their first 50 customers never use. Here is what to defer for v2:
API access: No customer will need API access until you have proven the product works. Build it in v2 when customers ask for it.
Advanced reporting: Start with basic usage data. Custom reports and analytics exports are v2 features. Use an off-the-shelf analytics tool until your reporting needs are clear.
Enterprise SSO and SAML: Build standard email auth first. Add SSO when you land your first enterprise customer who requires it.
White-labelling: One brand, one product for v1. White-label is a sales conversation, not a launch requirement.
The pattern is the same across all SaaS products: build for your first 10 customers, not your imagined 1,000th. Your first customers will tell you what they actually need. Build that.
