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.
