Custom CRM Development
A CRM that mirrors how your team actually sells, not the other way around. From WhatsApp threads to multi-stage approvals, modeled in code.
What Custom CRM Delivers
- A Pipeline That Matches Your Sales Cycle: Most B2B sales teams hit a wall around year three with HubSpot or Pipedrive, the pipeline doesn't fit, custom fields turn into spaghetti, reports lie because nobody trusts the data. A custom CRM costs more upfront but pays back the first time you close a deal that didn't fit the SaaS schema.
- WhatsApp, Email and Phone in One Timeline: WhatsApp Business API, IMAP/Gmail and your VoIP feed into a unified contact timeline. No more "I think I told them via WhatsApp": the CRM has it.
- Reports Your CFO Actually Trusts: Forecast accuracy, win rate by source, sales cycle length, ramp time per rep, all calculated from the source data, not approximated by a third-party BI plugin.
- Role-Based Access Out of the Box: Sales reps see their accounts, regional managers see their territory, executives see the global pipeline. Salary, commission and pipeline value are gated per role.
- Migration That Keeps the History: We import every contact, deal, note and email thread from HubSpot, Salesforce or your spreadsheet swamp, preserving timestamps so legacy reports keep working.
- Automations You Can Read: No more black-box workflows. Every automation is JS in a versioned repo, with a dry-run mode, audit log and a UI for sales ops to review before promoting to production.
How We Build Your Custom CRM
- Pipeline Audit: We sit with your top reps for half a day each, mapping the real flow, including the workarounds that never made it into HubSpot.
- Data Model & Reports Spec: We sketch the entities, relationships and the dozen reports that decide if the project is a win. Sales ops signs them off before we write a line.
- Build in Two-Week Slices: Pipeline first, then channels, then automations, then reporting, each slice usable end-of-sprint by a small pilot squad.
- Migration Dress Rehearsal: We run the full import twice on a staging copy, diff results, and only flip the prod cutover when sales is comfortable.
- Cutover & Training: Migration on a Friday night, training on Monday morning. We sit on a video call all week to fix oddities live.
- Iterate on Real Usage: First two months we ship small fixes weekly. The things you didn't know you needed until reps used the system for real.
High-performance stack used by global leaders
React/Next.js/Angular on the frontend and Java 21 + Spring Boot + PostgreSQL 14 on the backend, the same stack that BBVA, ING, and Netflix use for their security and performance.

Custom CRM: FAQ
Why build instead of customize HubSpot or Salesforce?
When customization fees + per-seat licenses cross €60-80K/year, custom usually wins on a 3-year horizon, and you escape the per-feature pricing trap. Below that, customizing the SaaS is fine and we'll tell you so.
How much does it cost?
It is a custom build, so the price follows the sales process you actually have, how many channels feed it, how much history has to move across, and whether you need several countries, corporate single sign-on or sales forecasting. We would rather look at that with you on a free call with one of our engineers and send a real number than publish a range that fits almost nobody.
How long does it take?
A pilot pipeline can be live from 3 weeks and a full replacement usually takes 6 to 8 weeks. Multi-region rollouts run longer, and how much longer depends on the functionality rather than on a fixed calendar. Either way we deliver a usable slice every 2 weeks.
Can it integrate with our ERP / accounting?
Yes. We have wired CRMs to SAP, Holded, Sage, Odoo, NetSuite and in-house ERPs, either through their API or through scheduled file exchanges when that is what your finance team will sign off on.
Who owns the data?
You own everything, the database, the daily backups in your cloud account, the source code in your Git org. We hand over root credentials at go-live.
Can field reps use it on mobile?
Yes. The interface is responsive PWA by default; if you need offline-first or barcode scanning we add a React Native app on the same backend in 2-3 extra weeks.
What about GDPR and audit trails?
Every read/write of personal data is logged with user, timestamp, IP and field-level diff. Right-to-erasure is a one-click flow that scrubs across the database, blob storage and search index.
What stays after launch?
You keep the repo, the infra, the runbook and a 30/60/90 retainer if you want it. We don't lock you into a managed-hosting cage.
Do you work with clients globally?
Yes. We work fully remote with clients across Spain, Europe, the US and LATAM. Time zones, video calls and live demos at every milestone.
