How much does custom software development cost in Spain in 2026?
How much custom software development costs in Spain in 2026, what drives the budget and how to choose the right solution for your company.
If you are thinking about building an application for your company, automating processes or replacing software that no longer meets your needs, you have probably asked yourself: how much does custom software development cost?
In Spain, a business software project can cost from around €10,000 to well over €100,000, depending on the features, the integrations and the complexity of the project.
But what makes one application cost €15,000 and another €80,000?
Indicative custom software prices in 2026
Every project is different, but these are some indicative ranges for 2026:
| Type of project | Approximate cost |
|---|---|
| Simple internal app | €10,000 – €20,000 |
| Business management software | €15,000 – €40,000 |
| Platform with integrations | €25,000 – €60,000 |
| Software with artificial intelligence | €30,000 – €80,000 |
| Complex enterprise platform | From €60,000 |
These figures are estimates, not fixed rates. The final budget depends on each company’s requirements.
For example, an app to manage clients and tasks does not need the same investment as a platform connected to an ERP, a CRM and an artificial intelligence system.
What drives the price?
1. Features
The more operations the software has to perform, the more development work it takes.
Managing clients, issuing invoices, tracking case files or automating approvals are different features, and each one needs analysis, development and testing.
That is why it matters to identify what the company really needs now and what can wait for a second phase.
2. Integrations
Many companies already use tools such as Microsoft 365, Salesforce, Holded, Odoo or in-house systems.
Connecting the new software to these platforms saves work and avoids duplicate data, but it also affects the budget. The cost depends largely on the integration options each system offers.
3. Artificial intelligence
AI can classify documents, extract information, let people query business data in plain language or automate certain tasks.
The cost, however, depends on what information has to be processed, where it is stored and how it connects to existing applications. Adding a document summary feature is not the same as building a private AI system for a company.
4. Security and maintenance
User permissions, data protection, backups and maintenance all need to be included.
Business software has to keep working properly after launch. So it pays to know from the start what the budget includes and what the ongoing costs will be.
How long does it take to build an application?
A relatively simple project can take between one and three months.
A business platform with several features and integrations may need between three and six months, and the most complex projects can take longer.
A good practice is to build in phases. That way the company can start using the core features without waiting for the whole platform to be finished.
Is it better to build your own software or buy an existing one?
It is worth asking this before investing.
Sometimes an off-the-shelf tool meets a company’s needs perfectly. Other times the problem appears when employees have to adapt their work to several programs, enter the same information over and over, or do tasks by hand because the applications are not connected.
In those cases there are three options: buy an existing solution, integrate the tools you already have, or build custom software. We go into more detail in Custom software vs. off-the-shelf apps: how to decide.
The decision should depend on the problem you want to solve, the budget and the long-term costs. To estimate what manual work costs you today, try our hidden-cost calculator.
How do you find out what your project would cost?
Before asking for a quote, try to answer these questions:
- What problem do you want to solve?
- Who will use the application?
- What tasks should it perform?
- Does it need to connect to other software?
- What information will it manage?
You do not need technical knowledge or a full list of features. A clear explanation of the problem is enough for an initial assessment and to work out which solution makes the most sense.
