Some companies offer services whereby you enter information once, and they apply for the credentials on your behalf, remind you of expiring licenses, and the like.

This can be extremely convenient, but the questionnaires can also be incredibly long.  For example, one questionnaire has over 800 questions!  Furthermore, you will have a long list of organizations from which to choose.  Today there are an estimated 250 credentialing verification organizations. Unfortunately for some, enlisting the aid of a professional service may be cost prohibitive.  Depending on what is provided, fees may range from $5,000 to $7,000. However, time spent on credentialing keeps staff from other valuable duties that, if neglected, could end up costing the practice.
