Who this is for
Founders and small teams with a specific idea who need to validate it with real users before paying for a fully featured platform. See What Should Be Included in an MVP for how we decide what is in scope.
MVP, production web application or SaaS product — which one?
These are three different things, and most projects start with the first or second.
An MVP
The smallest usable product that lets a real user complete the core workflow end to end, so you can test whether the idea works. Not a prototype that only looks finished, and not a feature-complete platform: cutting scope deliberately is the point.
A production web application
Software a business runs on: defined roles and permissions, integrations, testing and a maintenance arrangement, usually for one organisation. See Web Application Development.
A scalable SaaS product
Software sold to many customers: separate data per customer, subscriptions and billing, onboarding and admin tools, usage limits and scaling. It grows out of a validated MVP. Not every project we build is a SaaS product — most of our own systems are internal tools or demonstrations, and Clinic Records, which shows the multi-tenant pattern, is a demonstration platform that is not publicly launched.
What decides the scope of a first version
The number of distinct actions in the core workflow, the data it has to store, the outside services it must call (payments, email, AI), whether it needs more than one role from day one, and the hosting and security expectations. Each one moves the build, so the first version is written down in advance: what is in it and what waits until usage shows it is needed. You receive a working, tested and deployed first version with handover documentation.
When not to build a custom MVP
If an existing SaaS product or a no-code tool can run the core workflow well enough to test whether people want it, start there: building custom before there is any evidence of demand is the expensive way to find out. A custom build makes sense when the workflow itself is the product and ready-made tools cannot express it. We say so when that is the case, rather than recommend a build that is not yet justified.
Beyond the MVP: what is added, and when
If the MVP validates, growth adds what real usage showed you need, not a feature list assembled before you had users:
Multi-tenancy and account management
Separating each customer's data cleanly becomes necessary once you have several paying accounts, and it is architected differently from a single-user MVP. Clinic Records shows the pattern in our own code — each clinic's data isolated with PostgreSQL row-level security, with roles and an audit log — on synthetic data, without live customers.
Subscriptions, billing and usage limits
Recurring billing, plan tiers and usage limits — see How to Plan Payments and Subscriptions in a SaaS Product for how this is designed without becoming its own project risk.
User roles, admin tools and onboarding
Multi-role support (see How to Plan Roles and Permissions in a Web Application), an admin view for your own team and an onboarding flow for new accounts typically arrive in this phase, not the MVP.
AI features, integrations, analytics and support
Product-embedded AI features (see How to Add AI to a SaaS Product), third-party integrations, usage analytics and a support workflow — added based on what real customers need.
Scaling and maintenance
As usage grows, infrastructure and maintenance needs change and are planned as ongoing product work, not assumed to be a one-time build. See Web Application Development for the maintenance discipline this follows.
How it works
- 1
Pin down the one core workflow
What a real user must be able to complete end to end for the idea to be tested.
- 2
Cut the scope to what validates it
Everything else is written down as later, not dropped silently.
- 3
Build it end to end
Basic authentication, one primary role, a database and a minimal but real interface.
- 4
Test with real users
Check the core workflow with the people you want to validate it with.
- 5
Deploy and hand over
A working first version in production, with documentation.
- 6
Decide what comes next from usage
Billing, multi-tenancy, roles and scaling are added when real usage shows they are needed.

Questions
How is this different from a prototype or a design mockup?+
An MVP is a real, working product a user can actually use end to end — not a clickable mockup that only simulates functionality.
Do you only build MVPs, or also grow the product afterward?+
Both — this page covers the full path, from a narrow first validation build through multi-tenancy, billing, roles and scaling as the product grows.
When should multi-tenancy be added?+
Once you have (or are about to have) multiple paying accounts — retrofitting it later is more expensive than planning for it once it's genuinely needed.
Will you push me to add more features than I need?+
No — the point of an MVP is deliberately narrow scope; we'll say directly if a requested feature should wait until after validation.
What if the idea needs to pivot after launch?+
That's a normal, expected outcome of validation — a narrowly-scoped MVP is specifically easier to adapt than an over-built platform would be.
