Custom CRM development

Evicron, an AI and custom software studio founded in Barcelona in 2019, builds custom CRMs for companies that have outgrown spreadsheets or a standard CRM. We have delivered more than 200 projects across 12 sectors, including an AI-powered mortgage CRM for Hipteca, and we work by one fixed rule: the software adapts to your sales process, not the other way round — and the code is yours.

When a custom CRM pays off

Most companies start with a subscription CRM, and rightly so: it is cheap at first and quick to set up. The trouble starts when the sales process grows and the tool does not: stages that do not match how you actually sell, custom fields that multiply, integrations locked behind the higher plan and a per-user licence bill that climbs every year.

A custom CRM pays off in three specific situations:

• Your sales process is your competitive edge and a generic pipeline flattens it: deals with many parties, long cycles, specific documentation or business rules of your own.
• You pay for dozens of users and the licence cost already exceeds what owning the system would cost.
• You need integrations the standard tool does not allow: your ERP, your invoicing, your client portal, your telephony or your own data.

If a standard CRM covers 90 % of your operation, we will tell you in the first session. We do not build software where none is needed.

What an Evicron custom CRM includes

• Pipeline and stages mirroring your real process, with the fields, documents and rules you actually use — and nothing else.
• Client and opportunity records with full history: calls, emails, meetings, documents and tasks in one place.
• Built-in AI where it adds value: document digitisation with OCR, assistants that query the database in plain language, automatic call and email summaries, lead scoring or assisted proposal writing.
• Integrations: email, calendar (Google and Apple), telephony, ERP, invoicing and client portal, with an API of your own for whatever comes next.
• Calendar and mobile: the CRM calendar syncs with each salesperson’s phone, as we did at Hipteca with an iCal feed.
• Data migration from Excel, Google Sheets or your current CRM, validated before go-live.

A real case: Hipteca’s mortgage CRM

For Hipteca, a mortgage advisory in the Maresme area, we replaced spreadsheets with a custom AI-powered CRM covering the full lifecycle of a mortgage operation, from the pre-assessment form to signing. Claude digitises the handwritten forms that advisers photograph with their phones, extracting around 30 fields per form, and a conversational assistant answers questions about the live database without making data up. The interface is bilingual Catalan-Spanish and the calendar syncs with each adviser’s phone.

For ForConnect, Forcadell’s marketplace of home-service professionals, we built a sales CRM integrated into the platform itself, with AI-powered search and quotes in under 24 hours — another example of software that fits a demanding commercial operation instead of forcing a mould onto it.

Price and timeline

An Evicron custom CRM starts at €12,000, with a typical timeline of 3 to 6 months depending on scope. The quote is fixed after a free initial consultation. We work in weekly sprints with the first clickable demo in week two, so you see the pipeline running on your data before the project goes further.

We build on a proven stack — React, Next.js, Node.js, PostgreSQL or Firebase, and Claude, GPT or Gemini for the AI features — and deploy on European infrastructure. At the end we hand over the full Git repository: no per-user licences, no lock-in. If you need a broader platform than a CRM, see custom software; if you want to add AI to a CRM you already have, see applied AI.
