Sage accounting software
We use Sage acounts and payroll software in our office... our Bursar loves it...
I love their telephone support; it is second to none. I've never yet failed to get a straight answer from someone who understands how sage has been installed on our network. When you're feeling stressed, with the Bursar breathing down your neck and your next paypacket depending on you resolving the issue of a missing activation key (bursar threw it away :doh:) and Sage doesn't want to accept a new key anyway... a cheerful British voice dealing with the problem without resorting to 20 pages of script is WONDERFUL!
