What does the company do well? T-Sheets is an excellent and excellent tool for time tracking. My company is all-remote staff and we use it primarily to keep track of part-time employees. It is extremely efficient in that regard. It has an incredibly easy-to-use interface and, when the site occasionally bugs, as all do, the support staff is excellent.
What does the company not do well? My major complaint is that base fees increase the overall cost. Additionally, as stated before, the site can be buggy sometimes, though that's not a huge issue.
What do you wish you had known about the company before using? The only thing I can think of is that I wasn't immediately aware of the extremely helpful app.
