How much does it cost to build a SaaS MVP (2026)

If you're thinking about launching a SaaS, the first question that shows up is the uncomfortable one: how much is this going to cost me? And the honest answer is: it depends on how clearly you've defined the scope. The fuzzier it is, the more expensive and the longer it gets. Let's put real numbers on it for 2026.

What an MVP is, without the marketing

An MVP (Minimum Viable Product) is the smallest version of the product that solves the core problem and lets a real user use it, pay (or sign up, depending on the model) and give you feedback. It's not a prototype, it's not a landing page with a form. It's working software, with a database, authentication and the main flows ready for production.

If you're still not entirely sure what a SaaS is or whether your business needs one, you should first read what a SaaS is and when a small business should build its own.

The real ranges in 2026

A note: these are ranges for a qualified technical team in Argentina billing in pesos. If you compare them against foreign studios billing in dollars, the numbers double or triple.

Minimum MVP (US$5,330 – US$10,000)

Good for validating a very narrow hypothesis. A single main entity (e.g. appointment scheduling, a product catalog, a task list), a single user role, basic authentication, a minimal admin panel. No multi-tenant yet, no complex integrations, no automatic recurring billing (you charge manually at first).

Good when: you have a very clear use case, you want to validate before investing more, you already have a few users waiting.

Functional MVP (US$10,000 – US$20,000)

The one we recommend in most cases. Multi-tenant from day one (scaling later is much more expensive), 2 or 3 user roles, a full admin panel, basic integrations (email, WhatsApp, a payment gateway like Mercado Pago), recurring billing, minimal observability and CI/CD.

Good when: you've already validated the problem and you want to build a sellable product that can grow without being rewritten.

Robust MVP (US$20,000 – US$40,000+)

When the product demands complex business rules: granular permissions, approval workflows, advanced reporting, integrations with several external systems (ERPs, AFIP, third-party APIs), bulk data export, full auditing.

Good when: the end customer is a mid-size or large company that needs the product to plug into its existing operation.

What's included in any serious MVP

These aren't "optional", without them it's not production, it's a demo:

• Multi-tenant from day one. Even if you start with a single customer. Migrating to multi-tenant afterward costs between 30% and 60% of the original value.
• Robust authentication. With roles, basic permissions and password recovery. Not "store the user in localStorage".
• Admin panel. So you can operate the product without diving into the database.
• Logs and basic monitoring. Sentry, email alerts when something fails, minimal usage metrics.
• CI/CD. Automatic deploy to staging and production. No one hitting "deploy" from their laptop at 11 at night.
• Automatic backups. Daily, with at least 14 days of retention.
• HTTPS and your own domain. Obvious, but I'll spell it out.

If a quote doesn't include these points, it's not a SaaS MVP, it's a project you'll have to redo in six months.

What's NOT included (and surprises people)

• Brand design. Logo, visual identity, palette. That's the work of a designer or studio, separately, before development.
• Product content. Onboarding copy, transactional emails, marketing copy. You or a copywriter write that.
• Marketing and growth. Getting your first users isn't part of the MVP.
• Customer support. Help desk, chat, replies. You set that up or outsource it.
• Custom integrations with legacy systems. If your MVP needs to connect to a specific company's internal system, that's usually a separate project.

How to cut costs without killing the product

If the "Functional MVP" range is over budget, before dropping down to "Minimum MVP" try these cuts:

1. Charge manually for the first 6 months. Automatic recurring billing is expensive to build properly. As long as you have fewer than 50 customers, manual collection with Mercado Pago or bank transfer works fine.
2. Postpone the full admin panel. Start with direct database queries for edge cases. Build the panel once you have users asking for things.
3. Limit integrations to a single one at the start. Transactional email yes (Resend, Postmark), but the WhatsApp Business API or multiple gateways can wait.
4. Zero reporting. Let the customer export a CSV and build their own dashboards in a spreadsheet. Advanced reporting is a whole module.
5. A single customer in production at first. Multi-tenant in the code, but a single real customer. This reduces operational complexity without compromising the future.

What to avoid when getting a quote

• Hourly quotes with no cap. If there's no clear scope, there's no way to know how much you'll end up paying. Ask for a quote by milestones.
• "We'll see as we go." It's the most expensive phrase in software development. A serious MVP starts with a technical analysis of at least 2 weeks (paid or not, but documented either way) that defines scope, stack and architecture.
• Studios that promise 4 weeks. Unless the scope is tiny, a SaaS MVP in 4 weeks is built with shortcuts you'll pay double for in 6 months.
• The trendy stack. If someone proposes technologies because they're "trending" without justifying the problem they solve, that's a bad sign. The stack is chosen by problem, not by LinkedIn.

How we work at Manivela

Before throwing out fixed numbers, we run a first technical meeting where we map: main entities, users, critical integrations, billing model and expected volume. From there comes a quote by milestones with verifiable deliverables. If the scope changes along the way (something always changes), we quote it separately so we don't break the predictability of the initial budget.

A real case in production: Sodapp, a multi-tenant SaaS we designed and built end to end: architecture, frontend, backend, infrastructure and ongoing maintenance.
