I used ibiz a while ago when it was called iWork, it wasn't the easiest program to use but there weren't many choices. I recently upgraded because i started freelancing again. The current version is imposible to use, it is not intuitive in the least. Its really difficult to setup a client and add projects. This type of programs should be easy its really not complicated...

(This review is for the multi-user version) As a single-user app, iBiz worked pretty well. As a multi-user version running in a small office, it was a mixed bag. For instance, users could add new clients, but editing clients has to be done on the server. And there was no out-of-the-box easy way to link iBiz to a networked address book (LDAP or other).

Data loss and corruption were infrequent, but when it would happen, there was no good way to analyze or recover from the problem. Sometimes, a month of tracked time would just vanish. As a networked business system, it leaves a lot to be desired, but it has a lot of potential if the developers pay attention.

I've used iBiz for over two years now and thoroughly enjoy it. iBiz has made my life much easier when keeping track of the time I need to bill for, sending invoices to clients, and collecting payments, storing the information in iBiz and iBank. This program has saved more time for me than I ever thought would be possible with a time-tracking tool. I had tried about half a dozen other tools before I finally settled on iBiz, and two years later, I'm really happy I did.
My one small complaint is that the new version if iBiz4 does not appear to contain a great deal of new useful features (for me at least). I think they took a small step back with the design as well, eliminating a few of the more prominent icons that I found extremely helpful.

Garbage.

I tried to use iBiz 2 (starting when it was still called iWork), and experienced nothing but frustration with its endless stream of bugs and problems that were either replaced with new ones or never resolved. Eventually iBiz 3 appeared, and sure enough, many of the problems I had reported with iBiz 2 were STILL not fixed. I paid nearly $40 CAD for this junk; I thought it was overpriced, but needed something like this for my business, and at first glance it seemed nicer than the alternatives. But soon I discovered it had serious problems, such as miscalculations and data loss. One would be "fixed" and another one would turn up. No one could trust its numbers enough to actually use it for tracking time and billing clients (in other words, it's completely useless).

What a waste of time and money. I find it hilarious that the price has actually gone UP as the quality of the software remains consistently poor.

Billings is vastly superior, and even Studiometry (which I don't particularly like) is at least reliable and does what it's supposed to do.

This developer has proven himself incompetent and incapable of creating a quality, reliable application. iBank is even worse; you know you're in the wrong business when you can't even write software that does math properly, despite the fact that a computer doing all the actual computation.

Do yourself a BIG favor and steer clear of IGG's terrible software.

after trying v 3.1.5 for a few days i turned back to version 2.5.
ibiz 3.x is incredible slow (on an macbook with 2 gb ram an 2x2 ghz!) , takes over 100% cpu and several minutes to changes from project to invoice-view, meanwhile it blocks everything else. it has still no import or export function (i.ex for excel or filemaker), ittrashes addresses, has a bad gui, and so on. this programm is not worth a dime. very disappointed.
