Decision support
Questions buyers should ask
Can a Custom CRM act like an ERP?+
To an extent. A highly customized CRM can handle inventory and operational workflows, but it typically stops short of being the system of record for complex general ledger accounting.
Are ERPs only for large enterprises?+
No, but they do require a mature business process. Implementing an ERP before your processes are stable can lock in inefficiencies.
