SaaS Development Cost in 2026: Real Price Ranges

The real price range for a SaaS: EUR 40,000 to 300,000

Let us put the numbers on the table right away, without a sugar-coated marketing chart. Custom SaaS development sits between EUR 40,000 and 300,000. That spread looks enormous, but it covers two very different realities. At the bottom of the range, an MVP, the minimum viable product, usually costs between EUR 40,000 and 80,000: the smallest sellable version of your idea, able to collect a first subscription. At the top, up to EUR 300,000, we are talking about a mature platform, enriched module after module, with a broad functional scope, multiple integrations and strong scalability and security requirements. In between, the price follows the scope you decide to fund, not an opaque grid.

What separates a SaaS from a plain website or an internal application is its model: one piece of software serves several customers who pay a recurring subscription. That imposes a multi-tenant architecture, automated billing and scalability designed in from the start. These three building blocks explain why the floor for a SaaS, around EUR 40,000, sits above the floor for a custom website, which starts at EUR 1,500. These are not the same objects: from its very first version, a SaaS carries the commercial machinery required to sell accounts to several companies.

This grid is not lifted from a generic benchmark. Propulseo has designed two vertical SaaS products in-house, CoProFlex for condominium management and DocAgora for healthcare, on top of its client projects. These real products, billed and in production, anchor the ranges below in observed costs rather than back-of-the-napkin estimates. With 50+ projects delivered since 2024, the initial estimate usually lands close to the final budget.

The block above shows the official Propulseo range for a SaaS: 40,000 to 300,000 EUR, with a typical investment of EUR 40,000 to 80,000 for a market-ready MVP. Keep the logic in mind: you do not pay the 300,000 EUR of the dream product upfront; you fund the sellable version, you test it against the market, then you reinvest. That is exactly the trajectory of one of our in-house SaaS products, whose technical base was laid to absorb new features as usage grew rather than being frozen in an exhaustive upfront specification.

To put that EUR 40,000 floor in perspective, compare it with the other project families we price. A custom website starts at 1,500 EUR and climbs to 10,000 EUR for a full business site; a custom ERP sits between 15,000 and 150,000 EUR. A SaaS therefore starts markedly higher, not out of fashion but because even the most modest version already carries data isolation, recurring billing and an architecture designed for growth. On DocAgora, that foundation absorbed most of the effort of the first batch, before a single feature visible to the end user. That is what the floor of a SaaS pays for, and that is what separates it from a website or an internal tool.

What moves the price: scope, multi-tenancy, Stripe, scalability

A SaaS quote that lands at EUR 60,000 and another at EUR 250,000 do not describe the same product. Four variables explain almost all of the gap between the EUR 40,000 of a focused MVP and the 300,000 EUR of a full platform. Understanding them lets you discuss an estimate on the merits instead of accepting a reassuring round number.

1. The scope of the MVP. This is the first price lever. Each added feature looks reasonable in isolation, but the pile-up inflates the scope and drifts toward the full product. An MVP tightened around the core value proposition stays between EUR 40,000 and 80,000; the same project opened to every initial request can triple. Scope discipline is, first of all, budget discipline.
2. The complexity of multi-tenancy. A multi-tenant architecture lets one piece of software serve several customers while strictly isolating their data. Simple multi-tenancy, with RLS-based isolation, costs less than deep isolation with dedicated databases, which some sensitive industries require. For DocAgora, in healthcare, the bar for data structure and reliability weighs directly on the technical effort.
3. Integrations, starting with Stripe. Stripe billing is near systematic, to collect subscriptions, trials, invoices and webhooks. But every additional integration (third-party APIs, e-signature, accounting, industry connectors) adds development and testing. The more external systems you wire in from the start, the higher the needle climbs within the range.
4. The level of scalability and security. Supporting ten users or ten thousand does not call for the same architecture. Load, availability and compliance requirements make the difference between an MVP and a robust platform. CoProFlex, which models the administrative, document and financial flows of a condominium manager, illustrates the point: the reliability of the tracking conditions the value of the product.

These four variables share one trait: they are decided at scoping time, not along the way. That is why the upfront assessment matters as much as the code. A clear scope, data isolation sized to the real need and a list of integrations frozen from the start prevent the most common overruns. The quality of that structured data serves well beyond the product, too: semantically complete content, backed by original data, is now picked up far better by search engines, classic and generative alike.

MVP cost versus full product: what each envelope covers

The question comes up constantly: should you aim straight for a full product or start with an MVP? In cost terms, the answer is clear-cut. A market-ready MVP costs between EUR 40,000 and 80,000, while a mature SaaS can reach 300,000 EUR. But the right angle is not only the amount: it is what each envelope contains and when you start selling. The table below puts the two approaches side by side.

The reading is unambiguous. The MVP is not a cut-rate version: it is the version that sells earliest, with the financial risk spread out. The full product, at 300,000 EUR, is not a different project; it is the destination of the same product once modules stack up at the pace of user feedback. Selling from the MVP changes everything: you measure real willingness to pay, the only reliable market signal, not declared interest. Our SaaS products DocAgora and CoProFlex have run on this Stripe subscription model since they went to market, which validates the MVP-then-enrich trajectory.

Let us translate the gap into simple arithmetic. Between the bottom of the MVP envelope, around EUR 40,000, and the ceiling of a full SaaS at 300,000 EUR, the multiplier exceeds seven. But that factor of seven does not measure a leap in quality: it measures an accumulation of scope. The EUR 40,000 to 80,000 MVP covers the core value, sign-up, multi-tenancy and Stripe; everything else, up to the 300,000 EUR, consists of modules you only add if the market demands them. Paying for the whole thing upfront means funding features no sale has yet proven useful. For DocAgora, in healthcare, we first stabilized the structure and reliability of the data before opening secondary modules: the order of the batches directly protected the budget.

One often underestimated factor weighs on this calculation: how fast you can take care of your first prospects. A product that sells earlier means a sales cycle that starts earlier, and responsiveness has a measured impact on how well opportunities qualify. Better an MVP that collects revenue early than a perfect product that ships late. That reflex of fast go-to-market extends beyond the product itself: at a time when a majority of Google SERPs display an AI-generated result, a SaaS that produces clean, fresh data early feeds a visibility that no longer depends on classic SEO alone.

Budgeting your SaaS in stages: spread the investment, reduce the risk

Rather than signing a single check for the entire dream product, the healthiest method is to budget in stages. Each batch funds a validated building block, and each validation gates the next. This logic spreads the investment between the 40,000 EUR floor and the 300,000 EUR ceiling, while keeping a permanent feedback loop. Here is the sequence we apply on every custom SaaS.

The common thread of this approach is the increment. Moving forward on solid ground at every batch is as true for a software product as for a visibility strategy: it is the same discipline of validated building blocks that structures a pillar-and-spoke content architecture, whose ranking gains studies have measured. On a productivity SaaS, this logic allowed us to concentrate the first effort on the core value and a scalable base, then add features as usage grew, without a rewrite.

Concretely, this breakdown turns an intimidating number into a series of tenable decisions. Instead of committing in one block to an envelope that can reach 300,000 EUR, you first validate batch 0 and the MVP, the low end around EUR 40,000 to 80,000, before any larger commitment. Each following batch is only triggered once the previous one is live and, ideally, already generating revenue. Scope discipline acts here as a budget guardrail: content structured as clear lists, like the steps above, is not just a way of presenting; it is also the format generative engines pick up most readily, with a majority share of AI citations coming from list-organized content. On this type of SaaS, it is exactly this sequencing that laid a scalable base in the first batch, then stacked features without ever rewriting the core.

Beyond the amounts, one point matters as much as the number: who builds. Your SaaS is built by the Propulseo team, the same one that designs our vertical SaaS products, with no outsourcing of core development. And with our commitment, reply within 24 hours, no strings attached, follow-up stays responsive during the build and after launch.

Funding your SaaS: levers to support a EUR 40,000 to 300,000 budget

That leaves the awkward question: where do the funds for a six-figure project come from? Between the 40,000 EUR floor for an MVP and the 300,000 EUR ceiling for a full platform, several levers exist, and the batch-based breakdown makes them far more accessible than lump-sum financing. The guiding idea: align the pace of the funding with the pace of deliveries and first sales.

1. Self-funding spread across batches. This is the most natural lever once the budget is broken down. You fund batch 0 and the MVP (EUR 40,000 to 80,000) out of your own pocket, put it on the market, then the first Stripe subscriptions help finance the next modules. The investment is never concentrated in one big build.
2. Recurring revenue from the SaaS itself. The specificity of a SaaS is the subscription. As soon as the MVP starts collecting, the product generates recurring cash that can be reinvested in what comes next. Our in-house SaaS products CoProFlex and DocAgora run on this Stripe subscription model: the product partly funds its own growth, which softens the climb toward the top of the range.
3. Public schemes and bank financing. Depending on your situation, innovation or digital support schemes and bank loans can back a software project. Amounts, conditions and eligibility depend on your profile and the current year.
4. Raising funds to accelerate. If the ambition is fast growth, a raise can fund the move from MVP to full product. But it assumes you have proven the market first: a sellable MVP that collects subscriptions is the strongest argument you can put in front of an investor, far stronger than a slide deck with no product.

In every case, it is the traction of the MVP that unlocks the rest. A sellable product already collecting Stripe subscriptions speaks louder than any forecast: it proves real willingness to pay, the only signal that convinces a banker and an investor alike. This logic of proof before commitment also applies to the visibility of the product. Search is shifting toward generative assistants, with hundreds of millions of combined users across ChatGPT and Perplexity, and those engines cite fresh, structured sources first. A SaaS that generates clean data early builds a reusable editorial asset, instead of having to produce everything after the fact.

Whatever the lever, the principle stays the same: an MVP framed between EUR 40,000 and 80,000 is the healthiest starting point, because it turns an idea into a product that earns before you commit the rest of the envelope. It is also the best funding argument, internal or external. A SaaS that is well architected from the MVP produces clean, up-to-date data as a bonus, hence exploitable well beyond the tool, at a time when search is shifting to generative engines and the freshness of sources conditions the ability to get cited.
