Switching from ADP, Pacific Timesheet has been nothing short of a god-send in terms of our employees completing their timesheets. It is more intuitive, straightforward, and completely uncluttered with extraneous info employees don't need. Most of all, our employees love that we can pre-load time coding in, so they choose what they worked on and how much time, and the system does the rest.
I love everything about it, but they could improve their website a bit. It's stuck in 2005 and could be updated to (1) look more modern, and (2) be mobile-friendly.
Pacific Timesheet is very easy to use as an employee submitting timesheets, requesting time off, and calculating remaining vacation time/sick time, etc.
A lot of the PTO balances are shown in hours, which is very useful for admin, but slightly less useful for a user thinking in terms of days rather than hours. Not a big deal but worth noting.
