Hi WeeFlower,
I haven't used TAS payroll software so I can't comment on that. However I can recommend Collsoft payroll software. It's reasonably priced and very user friendly. The Collsoft team have always been very helpful with any queries I've had and have made modifications based on suggestions from users. I have no affiliation with them except as a happy customer and I've been using the software since 2003.
The software can be downloaded as a free trial for 40 days, so you can try it out and see what you think.
Hope this helps.
