SaaS Development
Product architecture built for post-launch pressure.
In short
SaaS development is the end-to-end build of a subscription software product: data modelling, backend, frontend, billing, deployment and the operational tooling around it. Offsage builds SaaS platforms, MVPs, internal tools and mobile applications on PostgreSQL, Prisma and Supabase with typed API layers. Custom SaaS MVPs start at $25,000 and mobile applications at $30,000.
Key takeaways
- Custom SaaS MVP development starts at $25,000; mobile applications start at $30,000.
- Data models are designed for the life of the business rather than the demo — most products meet their third feature request within weeks of launch.
- Builds run on PostgreSQL, Prisma and Supabase with typed API layers, containerised and deployed on AWS.
- Founder-led delivery means the people who scope the product are the people who build it.

How this works
Most products face their third feature request within weeks of launch, which is when a schema designed for the pitch starts fighting the team building on it. Offsage designs data models, permissions and API boundaries for the shape the product is heading toward, so the first significant extension is an addition rather than a migration.
The stack is deliberately unexotic: PostgreSQL, Prisma, typed API layers, containerised deployment. These are technologies with long support horizons and a large hiring pool, which matters more to a company that has to maintain the product than novelty does. Where a managed service shortens the path — Supabase for auth and storage, AWS for compute — it is used, with the trade-off stated rather than assumed.
Delivery is founder-led and iterative. Each cycle ends in something you can click and give to a real user, not a status update. Instrumentation and event tracking ship with the product rather than being retrofitted, so the decisions after launch are made on real usage rather than opinion.

Indicative pricing
Directional starting points, not ceilings. Final scope is agreed after a free 30-minute strategy call.
Discovery and scoping
Product discovery producing a costed scope, data model outline, stack decision record and delivery sequence. Credited against the build if you proceed.
$2,500
Custom SaaS MVP
A production-grade MVP: schema, API, application, authentication, billing and deployment, instrumented so launch decisions are made on real usage.
From $25,000
Mobile applications
Cross-platform or native mobile applications sharing the same backend and data model as your web product.
From $30,000
ERP and HRMS systems
Internal operations and HR systems scoped per integration count and user role complexity. Quoted after discovery.

Questions on saas development
Custom SaaS MVP development at Offsage starts at $25,000. Final cost depends on the number of user roles, integrations, and whether billing and multi-tenancy are in scope for the first release. The discovery engagement produces a costed scope before you commit to a build.
PostgreSQL with Prisma as the data layer, typed API services, and Supabase where managed auth and storage shorten the path. Deployment is containerised on AWS. These are chosen for long support horizons and hiring availability rather than novelty.
Yes. The usual first step is a technical review covering schema, test coverage, dependency health and deployment, followed by an honest assessment of whether continuing or rebuilding is the better path. Both outcomes are reported, including when the answer is to keep what exists.
Yes, and they share the same backend and data model as the web product. Mobile applications start at $30,000. Where a cross-platform build satisfies the requirement it is recommended, since it halves the maintenance surface.
You do. The repository, infrastructure configuration and documentation are yours, and the build is structured so another team could pick it up — which is also the reason the stack avoids proprietary lock-in.
