Custom software
Wallion builds custom software for businesses that need solutions that work, not templates that almost fit.
Barcelona studio. Custom software for SMEs: apps, AI automations, MVPs and internal tools.
We connect the tools you already pay for and remove stable manual steps with AI. For SMEs in Spain.

Technical and strategic advisory for software projects. From architecture evaluation to roadmap planning and code audits.
07
Experienced developers who integrate into your team. Temporary or permanent reinforcement with professionals we know and have worked with.
Everything starts with a Diagnosis — we audit your need, prototype the fix and give you a fixed quote. If you proceed, we build your tool in 4–8 weeks. Defined scope, fixed price, weekly progress.
€6,900–14,900 is one internal tool: one flow, after Diagnosis. You start with a €1,900 Diagnosis that includes the fixed quote for that build. Apps, MVPs and staffing are a written fixed price, not a second published grid. Monthly licence from €390. If you proceed, the Diagnosis is credited against the build.
4–8 weeks from fixed quote to live. You see progress every week — working software, not status decks.
Because the build price is a fraction of what traditional agencies charge. Wallion keeps the code and stays responsible for it running. Your data is always exportable, and source-code escrow is available.
Hosting, security updates, regulatory and API changes, a ceiling of small-change hours and business-hours support. Anything that must never go down runs on managed third-party services.
Small changes fit inside the licence ceiling. Bigger changes get a fixed quote in days — not a renegotiation. Scope is always written down.
