This is the single most-asked question we get from founders, and it deserves a more useful answer than "it depends," even though it does, in fact, depend. Here's how we actually break the estimate down when we scope a SaaS MVP.
What actually drives the cost
The biggest cost driver is the number of user-facing surfaces you need on day one. A web-only MVP is meaningfully cheaper to build and iterate on than one that needs web and mobile simultaneously — and in almost every case we recommend starting web-only unless mobile is core to the product, not a nice-to-have. The second driver is integration complexity: payments, calendar sync, third-party data feeds, and SSO each add real weeks, not days, especially once you account for their edge cases and error states. The third is your starting point — a founder with wireframes and a clear user flow gets to a working product faster than one starting from a napkin sketch, because so much of the early cost is actually decision-making, not typing code.
Rough pricing tiers
In rough terms, this maps onto three tiers. An MVP that validates a single core workflow — one user type, one primary action, minimal settings — typically lands in our Starter tier, roughly $5K and up, and can ship in six to ten weeks. A multi-tenant B2B product with role-based access, billing, and real admin tooling moves into our Growth tier, starting around $15K, because multi-tenancy and billing are where a surprising amount of hidden complexity lives. Anything with custom compliance requirements, complex integrations, or enterprise procurement needs sits in Enterprise territory, priced per scope.
Where budgets quietly blow up
The costs that blow past founders' initial estimates are rarely the ones they expect. Billing and subscription logic — proration, plan changes, failed payments, dunning — is deceptively involved even when you're using a managed provider like Stripe. Admin and back-office tooling gets forgotten in the pitch deck but is usually 20-30% of the actual build, because someone on your team needs a way to see and fix what customers are doing. And multi-tenancy edge cases — what happens when a user belongs to two organizations, what happens when an org is deleted mid-subscription — are exactly the kind of thing that's cheap to design for up front and expensive to retrofit.
How to control cost without cutting corners
The most reliable way to control cost without cutting quality is to build the thinnest version of the core workflow first and defer every settings screen, notification preference, and admin nicety that isn't required to prove the product works. Lean on managed services for anything that isn't your differentiator — authentication, payments, transactional email — instead of building them yourself. That's not a corner cut, it's the difference between spending your budget on the thing that makes your product worth paying for versus the plumbing every SaaS product needs.
