How Much Does Custom Software for Your Business Cost? 2026 Price Breakdown (Spain)

Quick answer: in Spain, in 2026, custom software for a business broadly costs between roughly €6,000 and over €120,000 depending on scope. An MVP (the first working version to validate the idea) usually runs between €6,000 and €18,000; a standard internal management app (several roles, admin panel, some integration) typically sits between €18,000 and €60,000; and a complex custom platform (multi-role, deep integrations with an ERP or external APIs, high scalability and sometimes AI) starts at €60,000 and easily exceeds €120,000. These are orientative ranges of the Spanish market, not a fixed SprintMarkt price list: the real cost depends on functional complexity, number of roles, integrations, whether it includes AI, and infrastructure. On top of that come recurring costs (hosting, maintenance, evolution) that almost nobody mentions upfront. We break it down below with real judgment, including when custom software is not worth it for you.

How much custom software costs in 2026: summary table of ranges

If you just want a figure to frame your budget, this is the snapshot of the Spanish market in 2026. We insist: these are orientative sector ranges, not closed SprintMarkt prices. The final budget depends on your project's specific scope, which we detail in the sections below.

Timelines are generic sector ranges, not a promise: they depend on scope, prior definition and how many integrations there are. The gap between the floor and ceiling of each range is driven mostly by integrations, the number of roles and whether there's AI, which is exactly what we cover next. If you want to go straight to the service, you'll find it at custom software and apps.

What custom software is and how it differs from off-the-shelf

Custom software is built specifically for your company, your processes and your way of working. The opposite is off-the-shelf or packaged software (a SaaS such as a commercial CRM, a generic ERP or a subscription management tool), which already exists and which you adapt to.

The difference isn't just technical, it's about fit:

When each one is the right call (important: custom is not always the answer). If your need is common —invoicing, accounting, a basic CRM, generic project management— a standard SaaS is almost always the sensible option: paying to develop what already exists, well solved, is throwing money away. Custom software makes sense when your process is your competitive advantage, when no market tool fits without deforming your business, or when the combined fees of several SaaS licenses start to exceed what owning something of your own would cost. If your case is more of an ERP, the comparison of custom ERP vs Odoo or SAP can help.

What really drives the price of your custom software

Two projects that "sound similar" can cost €15,000 or €90,000. The difference isn't in what you see on the outside, but in what's underneath. These are the factors that truly move the budget:

The rule of thumb: what you see (the interface) is the small part; roles, integrations and business rules are what truly move the bill. That's why a quote with no defined scope is worthless.

Common types of custom software and their ranges

Not all custom software is the same. These are the most frequent commissions among Spanish SMBs and companies, with their orientative market range. Remember: these are sector figures to frame your thinking, not closed prices.

- A custom CRM or ERP makes sense when your way of selling or producing doesn't fit a packaged tool; if in doubt, better to start by comparing with the standard options.

- An internal management platform is the typical case of the company that has worked for years with spreadsheets and emails and needs a system that reflects its operation.

- A portal or marketplace is the most expensive because it's almost never "a website": it's several roles, payment logic, panels and an architecture built to grow.

How it's built well: MVP first and by sprints

Custom software isn't delivered as a single finished piece at the end like a closed construction job. The sensible way to build it is by sprints (short work cycles, usually one to three weeks) and starting with an MVP: the minimum version that already does the essentials and can genuinely be used.

Why this approach protects your money:

That's why a "blind fixed price" with no discovery —no prior phase analyzing your processes, roles and integrations— is a red flag. Anyone who gives you an exact figure for complex software without having understood the scope is either covering themselves by inflating the price or will cut quality when the things they didn't ask about appear. A good process starts by understanding the problem; the honest number comes after that discovery, usually as a range that closes once the MVP is defined.

Recurring costs nobody mentions

The most expensive mistake in custom software is looking only at the price of "building it" and ignoring what it costs to keep it alive. Software isn't a job you deliver and forget: it's a system that has to work every single day and evolve with your business. These are the recurring costs you should budget from day one:

That's why "cheap" poorly-planned software ends up more expensive in the medium term: you pay little to build it and then pay in outages, improvised patches and redoing what wasn't thought through. The honest price of custom software includes its maintenance, not just its construction.

When investing in custom software is worth it

Investing in custom software is justified when it stops being an expense and becomes a lever: it saves you recurring manual work, gives you a capability competitors don't have, or supports a process that's the core of your business.

To illustrate what type of software fits each case, here are examples of SprintMarkt's own projects (as a reference for the type of product, with no result figures):

These examples serve to frame the type of software, not as a promise of results for your case. If what interests you is the artificial intelligence part inside your own software, we detail it in artificial intelligence services.

And conversely, to be honest: don't commission custom software if a standard tool already solves your need without contortions, if you're not yet clear on the process you want to digitize, or if the budget forces you into a half-done project that will be born incomplete. In those cases, a SaaS or waiting until the process is mature is the more profitable decision.

How to request a comparable quote (checklist)

The problem with asking several companies for quotes is that each understands something different and you end up comparing apples to oranges. To make quotes comparable, define this beforehand and hand it identically to everyone:

With that sheet, two quotes finally speak the same language, and be wary of anyone who gives you a closed number without having read any of this. If you like, tell us your case with those details and we'll give you a no-obligation quote, with honest judgment on whether custom software, a standard SaaS or a combination of both suits you: request it here.
