When should you get ERP support
In case of smaller businesses and start-ups, it is suggested to implement an enterprise-wide full installation. It would minimize retraining, future integrations with external applications.
Although the ideal configuration would be one ERP system for an entire organization, many larger organizations usually create an ERP system and then build upon the system and external interface for other stand-alone systems which may possibly be more powerful and perform better towards fulfilling an organization's needs. Usually this type of configuration can be time consuming and requires significant labour hours.
