Hey My name-
D-TAC does offer a free trial period; don’t like it, don’t use it simple as that. Purchased solutions they may give you a 30 day money back (which I have seen time and time again) takes 30 days to get off the ground sometimes + their way of keeping you (as a beta tester too ;). You could develop a system however it takes a lot of code, programming time and support costs, typical 6 months to over a year to work the bugs out.
Got to look at both sides of bankrupt companies both on the purchased side and hosting side, it does happen, hard to gaurantee honestly. How many carriers have we seen go under too that we/you had deposits with?
