Ongoing Support, System Optimization, and Follow-up:

There are a substantial number of companies who opt to not follow through on support after the rollout.
One of the disadvantages of small companies doing the implementation is their limited ability to provide post-implementation is their limited ability to provide post-implementation assistance and support.
In any case, the level of service needs to be there, and it is wise to arrange for post-implementation support.
Incurring cost is better than incurring systemic failure simply because something went wrong you didn't know what you did.
The good CRM is to contact the customer to make sure they are happy and functioning.
The implementation partner should access whether the customer is getting maximum benefit from the system.
Whenever there is update available, work with the implementation partner to ensure that the customization are not overwritten with the update's installation.
