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.

Why SaaS costs more than a regular app

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:

SaaS-specific build requirements

  • Multi-tenancy architecture so each customer's data is isolated and secure
  • Subscription billing via Stripe or similar, with plan management, upgrades, downgrades, and cancellations
  • User role management with admin, member, and viewer permissions
  • Onboarding flows that reduce time-to-value and improve activation rate
  • Usage metering if you bill by usage rather than flat rate
  • Email sequences for trial conversion and retention

Infrastructure and ongoing costs

  • Cloud hosting (AWS, GCP, Azure) typically $200 to $2,000/month depending on scale
  • Database backups and disaster recovery
  • Security audits if handling sensitive customer data
  • Customer support tooling (Intercom, Zendesk)
  • Analytics and monitoring (PostHog, Datadog, Sentry)
  • Ongoing development for new features, bug fixes, and performance improvements

How to build a SaaS MVP without overbuilding

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.

SaaS development cost: common questions

How much does it cost to build a SaaS product in Australia?

SaaS development in Australia typically costs $80,000 to $500,000. A simple SaaS MVP starts around $80K to $130K. Medium-complexity SaaS products with integrations and multiple user roles run $130K to $250K. Enterprise SaaS can exceed $400K. See the full app development cost guide for comparison against other app types.

Should I build a web app or mobile app for my SaaS?

Most B2B SaaS products start as web apps because business users work primarily from desktops and laptops. Web apps are also faster to update and do not require App Store approvals. A companion mobile app makes sense once the web product is proven. Start web, add mobile when users ask for it.

How long does it take to build a SaaS product?

A SaaS MVP typically takes 14 to 24 weeks from kickoff to launch. Complex SaaS products take 30 to 52 weeks. Timeline is directly related to scope. See our guide on how long app development takes for a detailed breakdown.
