Custom software
We build custom software in Barcelona: corporate websites, e-commerce, SaaS platforms, ERPs and mobile apps. From €3,500 — and you own the code, with no lock-in.
Evicron is an AI and software studio based in Barcelona. Since 2019 we have delivered more than 200 projects across 12 industries — corporate websites, e-commerce stores, SaaS platforms, ERPs, CRMs and mobile apps — working remotely with clients all over Europe. Fixed quotes, and one non-negotiable rule: you own the code.
Custom software or off-the-shelf?
Most companies start with standard tools, and that makes sense: they are cheap and quick to adopt. Problems begin when your operations no longer fit inside them — spreadsheets acting as a CRM, data duplicated across three apps that don’t talk to each other, per-seat licences that grow every year, and features nobody uses.
Custom software flips the logic: instead of bending your company to fit the tool, the tool is built around how you actually work. It matches your real processes, scales without per-user licences and evolves at the pace of your business, not a vendor’s roadmap.
What we build
- Corporate websites and e-commerce from €3,500, delivered in 4-6 weeks — fast, and built to rank on Google and AI-powered search.
- SaaS platforms for multiple users from €12,000, typically shipped in 3-6 months depending on scope.
- Custom ERPs and CRMs that mirror your sales or operations process instead of forcing you to change it.
- Mobile apps for iOS and Android with React Native, connected to your backend.
Two concrete examples: for Plata Garage we built the website and back office of a car dealership in Sabadell, with online reservations and deposits paid via Bizum; for Hipteca we developed a mortgage CRM with AI-powered OCR that digitises handwritten client forms — around 30 fields per photo — plus a conversational assistant that queries the database.
How we work
Every project moves through four phases: discovery, design, development, and launch and support. Discovery is free and ends with a fixed quote, so you know the full cost before committing. From there we work in weekly sprints, with the first clickable demo in week 2.
We build on a proven stack: React, Next.js and Astro on the frontend; Node.js, Python and PostgreSQL on the backend; React Native for mobile; deployed on Vercel, AWS or Google Cloud.
Why Evicron
- You own the code. At the end of the project we hand over the full Git repository. No per-seat licences, no lock-in — keep building with us or with any other team.
- Fixed quotes and realistic timelines: 4-6 weeks for a website, 3-6 months for a full SaaS platform.
- A small, direct team: you talk to the people building your product, with replies in under 24 hours.
- AI where it pays off: if your project benefits from automation or language models, we integrate them — see applied AI. And if visibility is what you need, take a look at our SEO and AI-ready websites.

Frequently asked questions
How much does custom software development cost? +
It depends on scope: at Evicron, corporate websites start at €3,500 and SaaS platforms at €12,000. After a free initial consultation we give you a fixed quote, so the price does not move during the project.
How long does it take to build custom software? +
A corporate website typically takes 4-6 weeks and a full SaaS platform 3-6 months. Evicron works in weekly sprints and delivers the first clickable demo in week 2, so you see real progress from the start.
Who owns the code? +
You do, always. At the end of every project, Evicron hands over the complete Git repository — no per-seat licences and no vendor lock-in. You can keep evolving the product with us or with any other team.
Should I build custom software or buy off-the-shelf? +
If a standard tool covers 90% of your operations, use it. Custom software pays off when your process is your competitive edge: it fits how you work, scales without per-user fees and evolves with your business. Evicron helps you decide in a free consultation before recommending anything.
What technologies does Evicron use? +
React, Next.js and Astro on the frontend; Node.js, Python and PostgreSQL on the backend; React Native for mobile apps. We deploy on Vercel, AWS or Google Cloud depending on each project's needs.
