# Custom CRM Development for Sales Teams That Outgrew HubSpot | Alher Tech > We build custom CRMs when off-the-shelf can't model your pipeline: bespoke stages, WhatsApp + email + phone, role-based reporting. 6-12 weeks to live. - Canonical page: https://alhertech.com/en/solutions/custom-crm-development/ - Site: Alher Tech (custom software, AI agents and SEO engineering, https://alhertech.com/) - Contact: https://alhertech.com/en/contact/ --- 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. ## Related services Neighbouring problems we solve, in case the one you arrived with is not the one worth solving first. - [Custom ERP Development](https://alhertech.com/en/solutions/custom-erp-development/): If the bottleneck is inventory, invoicing or production rather than the sales pipeline, the ERP side is where to start. - [Custom Software Development](https://alhertech.com/en/services/custom-software-development/): The broader service this sits inside, for operations that need something no CRM category describes. - [AI Agents & Automation](https://alhertech.com/en/services/ai-agents/): Qualification, follow-ups and data entry are the parts of a CRM most worth handing to an agent. - [All our services](https://alhertech.com/en/services/): The full catalogue, from web and mobile to AI, data and maintenance. ## 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? A focused custom CRM with channels, reporting and a clean migration is €35,000-€80,000 depending on integrations. Full enterprise CRMs with multi-region, SSO and advanced forecasting reach €120,000+. ### How long does it take? A pilot pipeline live in 6 weeks; a full replacement in 10-12 weeks; multi-region rollouts in 4-6 months. We always 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 proprietary ERPs via REST, SOAP, EDI or scheduled SFTP, whichever 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.
