Here's an honest breakdown from the builds we do at Vynuro.

Your three realistic options

1. Find a technical co-founder. Cheapest in cash, most expensive long term. A co-founder typically takes 20-50% of the company, and finding the right one can take months.

2. Hire freelancers by the hour. Hourly billing feels flexible, but scope creep is the norm. Without someone owning the architecture, many founders end up paying twice: once for the first version and again to rebuild it.

3. Fixed-price MVP development. You agree on a scope, a price and a timeline before any code is written. You keep 100% of the equity and the code. This is the model we use for SaaS MVP development for non-technical founders.

What actually drives the price

• Number of core features. One core workflow (e.g. "users upload a file and get a report") is very different from five.
• Auth and roles. A single user type is simple. Teams, admins and permissions add time.
• Payments. Stripe subscriptions, trials and invoices are a solid chunk of work on their own.
• AI features. A chat or RAG feature over your own documents adds cost for retrieval, prompt design and testing.
• Admin panel and reporting. Often forgotten, always needed once you have paying users.

Typical ranges

• Scope + wireframes only: a few hundred dollars. Worth doing first, because it turns a fuzzy idea into a fixed build plan.
• Lean MVP with 1 core feature, auth and deployment: low thousands.
• Full MVP with admin, Stripe subscriptions and an AI feature: mid thousands, usually 4-8 weeks.

These are ranges, not quotes. The point of a fixed-price model is that you get one number after a scope call and it doesn't move unless you change the scope.

How to keep the cost down

1. Cut the MVP to the one workflow your first 10 customers will pay for.
2. Use boring, proven tech (Next.js, Node, PostgreSQL, Stripe) instead of something exotic.
3. Ask for weekly demos, so you catch misunderstandings in days, not months.
4. Make sure you own the repository and the hosting accounts from day one.

Questions to ask any developer before you pay

• Is the price fixed, and what exactly is in scope?
• Who owns the code and the accounts?
• How often will I see working software?
• What happens after launch: docs, handover, support?

If you want a second opinion on your scope, you can hire a developer to build your SaaS MVP on a fixed price with Vynuro, or simply use the checklist above when you talk to anyone else.

1. Start with one painful workflow, not a feature list

Founders usually arrive with a list of 30 features. We cut it down to one sentence: "A [user] can [do the one painful thing] in [less time / for less money] than today." Every screen in the MVP has to support that sentence. Anything else (team roles, a mobile app, an analytics suite) goes into a "Version 2" document. It isn't thrown away. It's just put off until real users ask for it.

That one change usually removes 40–60% of the scope, and it's the main reason a fixed price is possible.

2. Scope in writing, priced up front

Before any code, we write a short spec: user roles, the screens (as rough wireframes), the data model, and what "done" means for each item. The founder signs off on that page. A fixed price only works when both sides agree on what's inside the box. Anything new becomes a small, separately priced change instead of quiet scope creep.

3. A boring, proven stack

For most SaaS MVPs we use:

• Next.js + React + TypeScript for the frontend and API routes
• PostgreSQL (often through Supabase or Prisma) for data
• Auth from a managed provider: email, Google login, password reset
• Stripe for subscriptions and billing
• Vercel or a small VPS for hosting

It isn't exciting, and that's the point. Every piece has good docs and plenty of developers who know it, so the founder can hire anyone to keep building later. No lock-in to us.

4. Build the skeleton first

Week one is the "walking skeleton": sign-up, login, an empty dashboard, a database, and a deploy pipeline, all live on a real URL. It looks plain, but it means every later feature lands in a working product rather than on someone's laptop. Founders get a link on day five and can click around themselves.

5. Weekly demos, not status reports

Every week ends with a short recorded demo of what changed and a staging link. Founders who can't read code can still judge a product they can use. Feedback comes in early, when it's cheap, not in week six, when it's expensive.

6. Add AI only where it removes work

Many MVPs we build now include AI, but only where it does a job a user would otherwise do by hand: summarising uploaded documents, drafting replies, or answering questions from the company's own knowledge base (retrieval-augmented generation, or RAG). We keep prompts and model calls in one server-side module, log every request, and cap usage per user, so an AI feature can't quietly run up the bill.

7. Launch checklist

Before handover we go through the same list every time:

• Error tracking and basic uptime monitoring
• Database backups turned on
• Environment secrets out of the codebase
• Stripe in live mode and tested with a real card
• Simple analytics on the one key action from step 1
• A README and a short Loom walkthrough of the codebase

8. Hand over everything

The founder owns the repo, the hosting accounts and the domain from day one. We don't keep anything hostage. An MVP is meant to be a cheap experiment, and the founder needs to be free to run the next one with or without us.

What this costs you, and what it doesn't

A focused MVP built this way usually costs a fraction of a "full product" quote, and more importantly, it gets real user feedback within about two months. Some founders find out they need to pivot. That's a cheap lesson at the MVP stage and a very expensive one after a year of building.

If you'd rather hand this whole process to a small team, you can see how we package it in our SaaS MVP development gig on Fiverr, or read more about our work at vynuro.tech.

Either way, our advice is the same: cut the scope to one painful workflow, put the price in writing, and ship something real users can try within a month.
