Custom software development in Barcelona

We design, build and maintain software made for your company: web applications, internal platforms, mobile apps and the integrations that connect them. From a small tool to a complete platform, the same team takes it from the first meeting to a working system.

What is custom software?

It's software designed and built for one company's processes, data and people. Unlike a generic product sold to many, the company owns it, decides how it evolves and pays no per-user licences. We handle the full cycle: understanding the problem, designing, coding, testing, launching and maintaining it.

What a system usually looks like

  1. Web and mobile app

    What your team and customers use.

  2. Your business rules

    The logic that today lives in formulas or in someone's head.

  3. Your own database

    Your data, organised and in your hands.

  4. Integrations

    ERP, CRM and accounting connected as they are.

What we build

  • Web applications

    Browser-based tools for customers, partners or staff: from a smart form to a complete management system.

  • Internal platforms

    Software for how your team works: operations, planning, quoting, inventory, field work.

  • Replacing spreadsheets

    Turning the spreadsheets the business depends on into an application with all the data in one place.

  • Customer and supplier portals

    Orders, documents, statuses and support at hand, so nobody has to call.

  • Mobile apps

    iOS and Android when the work happens away from a desk, usually sharing a backend with the web app.

  • APIs and integrations

    Connections between ERP, CRM, online shop, accounting or any system with an API. And the database when there isn't one.

  • Legacy modernisation

    Replacing or wrapping old systems step by step, without stopping the business.

  • Improvements and extensions

    Adding a feature, fixing a process or extending software you already have. We also take on small jobs.

When custom makes sense

  • The way you work is an advantage and generic software would flatten it
  • You pay for several tools and still fill gaps by hand
  • Per-user licences grow faster than the value they bring
  • You need integrations no vendor offers
  • You want to own the code and the data
  • A well-known product already covers almost everything at a reasonable price: we'll tell you
  • The process is standard (payroll, basic accounting): buying a product is better

How a project runs

  1. Analysis

    We talk to the people who will use the system. Result: written scope, risks and quote.

  2. Design

    Data, integrations and interface designed together and validated with a prototype.

  3. Iterative build

    Short cycles, each ending with a version you can try.

  4. Go-live

    Data migration, training and a planned switchover.

  5. Support and evolution

    Maintenance, security and new features when you need them.

Technology we usually use

We choose tools that can be maintained for years. If your team already uses others, we adapt.

Frequently asked questions

How much does custom software cost?

It depends on the number of users, the complexity of the business rules, the integrations and how critical the system is. We take on anything from small jobs of a few hundred euros to complete platforms. After a first conversation we send a written quote.

Do you take on small projects?

Yes. An integration between two programs, a simple internal tool or an improvement to software you already have are typical projects. You don't need a big budget to get started.

Do you work with companies outside Barcelona?

We're based in Barcelona and work with companies across Spain, in person or remotely.

Can you take over existing software?

Yes. We start with a technical review of the code and what should be kept, improved or replaced, and give it to you in writing before touching anything.

Who owns the code?

The client. Code, data and documentation are yours, in repositories you control.

What's holding you back?

A process, a product idea, a device, a set of systems that should talk to each other. A few lines are enough to get started.
