We had to run out and hook up a dial-up Internet router after a customer switched phone providers. He didn't understand he would lose his existing DSL Internet connection after the transfer. Vendors can also warn you if you'll need new equipment or have to reconfigure telephone or network computers to get new services working. If you have key features, such as three-way call transfer, caller ID, or remote Internet or network connections, make sure everything will work as planned after a conversion. Compare bottom line costs.
Some providers cover costs for required equipment.
I haven't heard of any that cover labor required for outside telephone or computer vendors. Often, alternate providers are more attractive when you're upgrading service or moving to a new location, because you'll have to spend money anyway. Lower cost and better service is what every business wants. Take time to make sure that's what you get, not just cheap talk and data.
