HR2000 has 6 software supports. You can always call in for support.
Basically, every week, there will be minor updates of program. You can always download the latest version from their website, but you need to call them to get the password.
If there are changes in government or bank requirements, their programmer will apply the changes normally within 1 or 2 weeks.

P/S: I worked there before, just resigned last month. If you are interested, I can give you the contact number.
