### 5/5 — Just what I have been looking for

*2024-11-12*

Finally, a beautifully simple time sheet app. Record your time per client and then when you’re ready to invoice - send to xero. You can choose to invoice all items recorded per client together, or check the ones you would like to invoice another time. Only used it for a few minutes, but it works for me! Great for solo consultants

### 2/5 — Not for multi-service lines business

*2024-08-02*

This is probably great for a sole proprietor but not a business that has multiple techs in the field!

### 1/5 — Not ready (for my purposes)

*2015-07-30*

Didn't have enough features for this to be useful to me. 
- bug in doing time sheets for previous days (end time defaults back to 'today') 
-can't set my own payment terms 
Couldn't see where I add tax 
-The time sheet is based on start end times, but no ability to minus break times off hours (or not specify exact times and just have hours) 
There is basis for a great tool - love the idea, but needs waaaay more features to be useful
