SaaS MVP Development with Authentication, Billing & Dashboard

A SaaS MVP with auth, billing and a dashboard is a real production codebase your first paying customers can sign up for: email and Google login, team workspaces, subscription plans with trials, your core feature built end to end and an admin view for you. It is not a prototype or a no-code assembly, but a standard Next.js and Supabase application with tests and CI. The goal is a first paid customer, not a demo.

A SaaS MVP costs $1,800 to $2,500 at PINCLER, our top price band. It is possible because a small senior team using Claude, GPT and Cursor writes the boilerplate, CRUD screens and test suite in hours rather than weeks, so our time goes into your core feature, security and the release. Scope is what moves the price, and the fixed quote never exceeds $2,500.

A SaaS MVP takes 18 to 28 days to build, the longest timeline we offer. Authentication, billing and the data model come first so there is something deployable within the first fortnight, then the core feature and admin views. You get a staging environment early and review progress against a written scope.

Billing runs on Stripe or Razorpay with subscription plans, trials, upgrades and failed-payment handling wired up rather than stubbed. Authentication supports email, Google and magic links through Supabase Auth, and transactional email goes through Resend or your own provider. All of it runs on accounts registered in your name.

The core feature is one well-defined workflow that makes your product worth paying for, agreed in the discovery call and written into the scope before we start. Everything around it, including login, workspaces, roles, billing, settings and admin, is included as standard. Additional features after launch are quoted as separate fixed-price sprints, each shipping something usable.

You own everything from day one: a standard Next.js, TypeScript and Supabase codebase in your GitHub repository, deployed to your own Vercel and Supabase accounts. Architecture documentation and a handover video mean another developer can continue it without speaking to us. There is no proprietary framework and no licence to keep paying.

Bubble, Softr and similar no-code platforms get you to a clickable product faster and are the right call for validating an idea before anyone pays. A paid boilerplate plus your own developer is cheaper still if you have that developer. Build custom when you have paying customers or a waiting list, when you will hire engineers onto the codebase later, or when no-code pricing and limits start to bite at real usage.

A SaaS MVP build is for founders with a validated idea, such as a waiting list, letters of intent or a service they already sell manually, who need a real product in weeks. If you have not yet spoken to twenty potential customers, spend the money on that instead, because the most expensive MVP is one nobody wanted. And if your idea genuinely needs a large product surface on day one, we will say so at the discovery call and propose what the first phase should cover.
