Vendors will represent themselves as being “omnipotent”, able to handle all groups within the practice, or all specialties within a healthcare facility and all functions.
While this may come as a welcome relief, it may not actually be the best solution for you.
Check thoroughly to see what specialties and what programs the vendor is capable of providing. You may want to have another vendor who focuses on a particular niche or feature that is not properly represented with the initial seller. Though the principle sounds like it would complicate matters, having more than one vendor, has additional benefits. Each one will want to please you and work harder to fulfill your needs due to competition. If one is not performing up to par in an area, you also have another vendor to fall back on.
Finally, make sure in your contract that your vendor will work with you during the transition phase if you decide to change vendor systems to make a seamless, smooth conversion.
