Key Criteria for ERP Selection in IT Resellers
Choosing the right ERP system is more than a technical project—it’s a strategic decision. These five criteria will help you make the right choice:
1. Industry-Specific Features
Do you need managed services billing, ticketing, or license management? Then industry-specific systems like Systemhaus.One or c‑entron are often the better fit.
2. Integration and Interfaces
An ERP system today needs to do more than just inventory management. Check how easily your ERP integrates with procurement tools like ITscope, webshops, or accounting software. Seamless integrations reduce manual work and boost productivity.
3. Flexibility and Scalability
Is your company growing quickly, or are your business models evolving? Systems like Odoo and weclapp offer modular structures that can be easily expanded as your needs change.
4. User-Friendliness and Team Adoption
An ERP system is only as good as its adoption. Look for an intuitive interface and training options to ensure your team fully embraces the new system.
5. Costs and Effort
Beyond licensing or cloud costs, consider the time and resources required for implementation and customization. In-house developments may work short-term but often lead to high maintenance demands in the long run.
