Assess Your Business Needs
Start by asking: What are your primary sales challenges? Are you struggling with lead follow-up? Do you need better reporting? Are you planning to scale soon?
- List your must-have features (e.g., email integration, mobile access)
- Identify pain points in your current process

- Dolibarr and EspoCRM can run on shared hosting
- SuiteCRM and Odoo may require VPS or dedicated servers
- Consider using Docker for easier deployment
If you lack in-house IT support, look for CRMs with strong community forums and documentation. SuiteCRM and Vtiger have active user communities that can help troubleshoot issues.
