Custom software development company in Spain
Custom software is an application designed and built specifically for your company's processes, instead of forcing your operations into a generic product. It pays off when your workflows are your competitive advantage, when you pay licenses for features you never use, or when no SaaS on the market covers what your operations actually need.
We design and build ERPs, CRMs, SaaS platforms and AI-powered systems from Madrid, with a senior team and 150+ delivered projects. The code is yours — no recurring licenses, no vendor lock-in.
When custom development beats SaaS or licensed software
Off-the-shelf SaaS works well for processes that are identical across companies: email, basic accounting, video calls. Custom development pays off in the processes that set you apart — bending your operations to fit generic software means giving up your competitive edge.
The practical rule is simple: if a SaaS covers more than 80% of what you need and your processes are standard, use it. If you live with parallel spreadsheets, fragile integrations between tools and constant workarounds to patch what the software does not cover, custom development is usually more profitable in the medium term. Licensing costs matter too: a per-seat SaaS that looks cheap today scales linearly with your headcount, while your own software is a one-off investment that pays for itself every year you skip the fees.
With custom software the code is a company asset. You own the roadmap, integrate natively with your current tools and evolve at the pace of your business without depending on a vendor's priorities. And when part of your operations is genuinely standard, we combine both: we build custom only what differentiates you and connect the rest via API.
At Soamee we have been building custom software for companies across Spain and Europe since 2017. For InfoAdex we built the platform that manages over 55 million advertising investment records; for Somos Música, the music licensing system used by more than 150,000 businesses in Spain.

Types of custom software we develop
From internal tools to full enterprise systems. Every project is designed around your real processes.
Custom ERPs
Business management systems with inventory, invoicing, purchasing, HR and reporting modules built around your operations. No per-seat licenses, native integration with your ecosystem.
Custom CRMs
Sales management built on your real sales process: pipelines, automations, scoring and integrations with your ERP, your email and your acquisition channels.
SaaS platforms
Multi-tenant B2B SaaS products ready to scale: subscriptions, billing, roles and permissions, public API and admin panel. From idea to launch.
Process automation
We remove repetitive manual work: data syncing between systems, document generation, approvals and end-to-end orchestrated workflows.
AI-powered software
Applications that embed LLMs and machine learning: automatic document classification, internal assistants, chatbots and predictive analytics on your data.
Legacy modernization
We migrate aging applications (Access, VB6, old .NET Framework, Excel turned de facto "ERP") to modern technology incrementally, without stopping your operations.
