SaaS Development Services

SaaS development is the process of building software delivered over the internet on a subscription basis, where one codebase serves multiple customers (tenants). What makes it different from building a single-customer application: (1) Multi-tenancy, the architecture must isolate each customer's data while running on shared infrastructure. (2) Subscription billing, recurring billing, trial management, plan changes, and usage-based pricing are core product features, not afterthoughts. (3) Role-based access, every SaaS product needs user, team, admin, and billing roles with appropriate permissions. (4) Observability, you're responsible for uptime and performance for all customers simultaneously, so monitoring and alerting are non-negotiable. (5) Scale, the architecture needs to handle growth without rebuilding at each new order of magnitude.

There are three models, each with different cost and isolation trade-offs. Row-level security (shared schema): all tenant data in shared tables with strict query-level isolation. Lowest infrastructure cost, easiest to scale operationally, right for B2C SaaS and SMB-focused products. Schema-per-tenant: each tenant gets their own schema within a shared database. Strong isolation, good compliance posture, manageable infrastructure cost, the right choice for most B2B SaaS products targeting growth-stage companies. Database-per-tenant: each customer gets a completely separate database. Maximum isolation, required for regulated industry buyers in healthcare and financial services, and for customers with strict data residency requirements. Higher infrastructure cost that scales with customer count. We recommend the model based on your target buyer and their procurement requirements, not a default preference.

We integrate Stripe Billing as the standard subscription layer, handling recurring billing, trial management, plan upgrades and downgrades, proration, and invoice generation. For usage-based billing (metering by API calls, seats, events, or other units), we implement Stripe Meters or build a custom metering system that reports usage to Stripe. Feature flags are implemented to control feature availability by plan without code deployments. If your pricing model is likely to evolve (and it will), we design the billing integration to support plan structure changes without breaking existing subscriptions.

A focused SaaS product, one core workflow, multi-tenancy, subscription billing, and a web interface, typically runs $25,000--$60,000. A more complete SaaS platform with multiple modules, mobile app, API for third-party integrations, and admin tooling runs $60,000--$150,000. SaaS products with complex data models, real-time features, or compliance requirements (HIPAA, SOC 2) run higher. Pricing is fixed cost based on scoped features, you know the number before development starts, not after.

A focused SaaS MVP with one core workflow, multi-tenancy, and subscription billing typically launches in 10–16 weeks. A more complete platform with multiple modules and enterprise integrations takes 16–24 weeks. We deliver working software every two weeks and hold milestone reviews before each payment, so you see progress throughout rather than only at launch. Timeline depends on scope complexity, the number of third-party integrations required, and how clearly the product requirements are defined at kickoff.

You own everything. All source code, infrastructure definitions, CI/CD configurations, documentation, and data are transferred to you at project end. We do not retain access to your systems after delivery, and we do not use proprietary frameworks that create lock-in. Your team or any future developer can take over the codebase without depending on us.
