Bill4Time

Pros: Accounting and timekeeping with B4T is fairly easy.
I like how you can log and track multiple timers and if you run over, you can go back and edit it.
The accounting features on the most basic plan are also quite good for even more advanced law firms. Even with the basic plan, you don't feel like you're being ripped off, as the account report features are crucial for my law firm, to keep up with collections.

Cons: The interface itself needs improvement. It looks rather outdated, and at times, it can take quite a while for the site to respond to your request.
Additionally, some of the features for more of the more advanced plans should be included in the basic plan as even small firms need access to the feature such as being able to manage your IOLTA.

Overall: Overall, I enjoy Bill4Time, even at its most basic plan. The most basic plan still has the abilities to keep up with a mid-size law firm. When everyone in your law firm uses Bill4Time effectively, it works even better. There will always be user error, but I do wish that in some ways they mitigated the chances of user error. Honestly, I would recommend Bill4Time to other law firms. Although it may not flash as many features as other systems, it packs a punch.
