The ease of use and the ability to customize the software to your company needs. I also like the fact that they are very helpful if you have any questions. I dislike that you have to have an account on their website to request a quote. I would recommend AcroTime because they have great customer service and they are very helpful. I would also recommend AcroTime because they have the best customer service. I have used AcroTime for several years now and it has been a great experience. I use it for payroll processing and time clock management.
