I like how well it works as far as being able to integrate with all my carriers (AT&T/Verizon/Sprint). There are some minor bugs here or there that can be improved but nothing major at this time. They have been very responsive when working with me through out our implementation process. We were looking for something that could help us get better control over who we give credit cards to so they would not just go in and use someone elses card without their permission. MindBill has helped solve this problem by giving me more detailed information about each person within the organization.
