What vendor lock-in is and how to avoid it

Vendor lock-in is a situation where changing the used system — to another system, another vendor, own infrastructure — is so hard or expensive that the company effectively has no real alternative. It's one of the biggest hidden business risks when choosing a CRM/ERP — and a risk no one advertises in the first sales conversation.

Vendor lock-in occurs in four main forms: (1) data lock-in — vendor-specific data format, partial or impossible export, (2) API lock-in — integrations written for specific APIs without competition equivalents, (3) training lock-in — the team knows only one system, retraining cost is huge, (4) contract lock-in — multi-year contracts with early termination penalties.

Vendor lock-in consequences are long-term: no price negotiations on licence hikes (Salesforce raised prices by 9% in 2024, customers had no alternative), no escape from a vendor with bad practices (e.g. data security policy change), inability to react quickly to regulatory changes, no control over your own business — the vendor dictates terms, not you.

Open source fundamentally eliminates vendor lock-in. First — the code is yours, you can fork it, hand it to another implementation agency, develop it in-house. Second — data is in a standard format (PostgreSQL), you can export it as SQL anytime and move it to any other system. Third — no licence fees eliminate the vendor's motivation to 'hold' you. Fourth — you can host the system on your own infrastructure, eliminating cloud-vendor dependency.

Practical strategy to minimise vendor lock-in when choosing CRM/ERP: ask about the procedure for full database export in standard format, check availability of REST API with full docs, avoid multi-year contracts with penalties, prefer systems with an active open-source community (vendor-independent), include 'exit cost' in TCO. If the vendor dodges these questions — it's a warning sign.
