Payroll Software

We're in the process of brining our accounting inside. We've got the accounting software covered but wanted to find out what people are using for payroll processing software. Right now we're 18 people on payroll and this will grow over the next year. We need the standard payroll pay-stub envelops. I'm not sure if it comes from their payroll system or not but our current payroll service gives us a floppy disk to take to K-Bank for the payroll direct deposits.

And suggestions or pointers?

Are there non-Thai packages that work for Thailand? Or better yet a web service.

Many thanks,
