What does the software or service do well? The software is very easy to use. Navigation is pretty good.
What does the software or service not do well? The visual appeal of the interface is not great and there are some areas of navigation that are not easily found. You have to dig around a little to find the page you are looking for. Expense reports have redundant fields.
What do you wish you had known about the software or service before using? Nothing really - It is good software just not as polished as ADP
Have you used a competitor to the software or service? If so, how does it compare? ADP - I prefer ADP but Paylocity is a very solid software.
