MJKPHOTO  Make sure you try Billings before you buy. Go through the program thoroughly because it has a very set way of doing things and if that doesn't fit your workflow, you will be terribly disappointed, as I am.

Billings tracks work through the use of projects and work slips that track time spent, (or flat rates, quantity, expenses, or mileage). But if you have multiple projects and different billing rates per client, you have a problem. For one, Billings doesn't seem to allow multiple projects on one invoice, which is very odd. That means you must have one project per client, with multiple work slips. But I have several projects for one client within any given billing period.

Tracking time. Billings has a nice timer feature, but again it is very limiting. There doesn't seem to be an easy way to indicate start and end date/times on invoices, even though you can track that information (but don't expect it to be intuitive or as easy as other reviews have indicated).

While the program does produce good looking invoices, designing your own is a cumbersome process.

Documentation leaves much to be desired. This program is counter to my workflow and has been most frustrating.

Sometimes template driven software is good to have, but not this program... at least not for my business. I wasted my money because I didn't have the time to properly try it out. Don't rely on reviews. Take the time to test it according to your own needs, even if the software is offered at a discounted price.  (Version 2.5.5)

VVARP  This is king of time tracking apps for Mac.

Easy to use, damn good looking and well designed - do I need to say more?  (Version 2.5.5)

MARIANOSPINA  I've paid for a Billings license a week ago but have not received the activation code, nor have anyone from Marketcircle answered my emails - Has anyone had any similar experiences with them an can provide a reasonable solution?  (Version 2.5.5)

XPLICIT  Billings is good at tracking time, but it's not good at a lot of other most important things:

1. Creating fully-customizable invoices isn't that easy because there is absolutely NO documentation on creating customized invoice templates, just a poor video that explaines things you can find out by yourself in about 10 minutes.

2. There seems to be no support for technical problems. I've written several emails, used their so called support contact form, etc., never got any answer.

What good is an application that can gather all necessary data for an invoice but doesn't let you create customized invoices hence you cannot send invoices to your clients?

Also 59 bucks is a lot of money for just a time-tracking application.  (Version 2.5.2)
