Utm5 as a billing looks good on paper but the support is very bad
I had the system install 2 years ago and it has never been completed.
While the cost of $5000 usd at the tim for the whole package seems cheap they will not fininsh it unless you keep paying.
I have a billing system that wont even print a bill.
It is a basic collector of data which my old billing is picking up.
Do yourself a a real good deal stay away.
This is not a comment made lightly you will be disapointed.
