How much does SaaS development cost?

A SaaS product is two products: the one your customers use, and the machinery that lets you run a business on it — accounts, billing, permissions, onboarding and an internal admin. Budgets go wrong when people only plan the first one.

What drives the cost

• Tenancy model. Shared database with tenant keys is the common, cost-effective default. Separate databases per customer add isolation — and operational work.
• Billing. A couple of monthly plans is simple. Seats, usage metering, trials, coupons, invoices and tax take real time, even with Stripe or Razorpay.
• Enterprise features. SSO, SCIM provisioning, audit logs and granular roles are what larger customers ask for in security reviews.
• Integrations. Each CRM, accounting tool or data warehouse your customers expect is its own mini-project.
• Customer-facing reporting. Dashboards and exports for your customers are harder than internal ones.

A sensible first version

1. Self-serve sign-up and onboarding to first value.
2. The core workflow, done well.
3. Two or three plans with Stripe or Razorpay.
4. Teams with basic roles.
5. An internal admin with impersonation for support.
6. Product analytics, so you learn what to build next.

Leave SSO, usage billing and custom reporting until a paying customer asks — but design the data model so adding them later isn't a rewrite.

The cost after launch

Hosting is usually modest at first. The real ongoing cost is a team that keeps shipping: SaaS that stops improving starts churning. Plan for a smaller monthly team after launch rather than a one-off project.
