Although everyone is now satisfied with the vendor, the program, the service and the contract, do not sign until there is an “opt out” or cancellation clause inserted.
If the system that you have elected to implement, no longer functions up to your expectations and you see a better system that works for you now or is more affordable, you don’t want to be locked into the system that you loathe. Having no means of opting out translates to having to throw thousands of dollars away to pay a vendor for a commitment while changing. If there is an early termination fee, know about this ahead of time. There should be no unplanned expenditures.
