Custom CRM development without a monthly licence
An alternative to Salesforce, HubSpot and Microsoft Dynamics — built around your sales process, NIS2 + GDPR built-in, hosted in EU data centres. €31k–€131k initial build, 5-year TCO 70%+ lower than SaaS CRMs at 100 sales users.
4 reasons that flip the TCO maths above 30 sales users
SaaS CRMs are competitive below 10-30 users. Above that, the monthly licence quickly starts eating the development budget — and the codebase is never yours.
Custom CRM — no licence trap
Salesforce, HubSpot, MS Dynamics: €75–€780 / user / month. For a 100-person team that is €0.5–€1.7M over 5 years. A custom CRM is €31k–€130k, then yours — 70%+ savings over 5 years.
Built around your pipeline
Off-the-shelf CRMs work with generic pipelines. A custom CRM has your lead typology, your multi-step B2B quoting, your vertical-specific fields and your approval flow.
GDPR + NIS2 compliance built-in
Data stored in your own data centre (Cloudflare EU, Hetzner, Hungarian Tier IV). Audit log, RBAC, MFA, encryption at rest. NIS2-ready from day zero — not a monthly licence drip.
Source code is yours
Git repository, documentation, infrastructure access — all yours. No vendor lock-in, no risk of licence hikes, no Salesforce roadmap that hits you uncomfortably 2 years from now.

Salesforce / HubSpot / Dynamics vs. custom CRM
SaaS CRMs are cheaper in year 0. By year 3-5 the monthly licence flips the maths — especially above 30 sales users.

| On-prem / EU data sovereignty | Limited | Full (Hetzner / Tier IV) |
