Exact Synergy is a great product with broad capability. It enables the usually hidden back office functions and data to be easily exposed to front office users. E.g. the financial state of an account is shown to a Sales Exec so he knows what to expect when he picks up the phone to call a customer.
The product has a flexible workflow engine which underpins functions such as calendars and opportunity management.
Its major draw back is it is relatively unknown product with limit user group outside the Netherlands.
Limited user groups and external integration to other ERPs.
Plan your implementation and design workflow working directly with Expericened users.
