NOBILLGATES  after having lots of troubles with ibiz 3 (scrambled or lost addressbook entries, ghost-invoice or orphaned invoices with no relation to customer, unusable interface, and more of these weird bugs), I switched to grandtotal last autumn and would never never never turn back.

STORMCHILD  Worst Mac software developer ever. This guy is completely incompetent. Stay away from this junk.

HIGHWAY OF LIFE  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.

KLAGRECA  Some of these reviews, I think, are alittle off base. Here is what I think is an objective review:

Layout -- easy, coherent and simple.

Tracking clients - integrates with Address Book. easy as pie.

Tracking projects --- good. navigation of adding events could be made easier.

Invoicing -- a couple of clicks and you've emailed an invoice to click. Nice.

Customizing templates -- err.. not much fun. Be sure to read their guide first.

Recording payments -- needs work here. There's a few ways to do it and its not clear how outstanding balances are managed.

Stability - no problems here.

Overall - its simple and mostly intuitive. Fully usable for a small business. Has some rough edges but workable with extra time.

To the previous grumpy folks: Give IGG a break. They're a small shop yet they are quick to respond to forum posts and emails. iBiz might have suffered lately since they've been pouring their time into iBank 3.

iBiz will be 5-star product after some reworking of the template and payment pieces. If you're a small biz and bill hourly for projects, this is a great solution and I don't hesitate to recc it.

STORMCHILD  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.  
(Version 3.1.9)

PHALERON  This program (at least the demo version I tried) has some serious issues with reliability. I like the interface a lot, especially the payment feature and the file-based timer triggers, but I would not trust it with time-tracking.  
(Version 3.1.7)

JMORGAN  ibiz for me was way too slow and buggy. I liked iratchet a lot but found timenet to be my favorite. i bougt it today and the service is very nice. quick replies  
(Version 3.1.6)

NOBILLGATES  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.  
(Version 3.1.5)

THIRSTYROBOT  I ditched iBiz and its performance/reliability issues long ago. For my needs, Billings is the better bet...with iRatchet placing a close second.  
(Version 3.1)

ANON BUD  I quit using this app a while back due to some strange behavior and thought I’d upgrade to this new version. What I’m getting now is completely unacceptable to me:

* Duplicates entries get added for no apparent reason

* Manual time and date entry is messed up and frustrating to accomplish

* iCal synch sometimes duplicates entries already logged

* iCal calendars in iBiz drop down menu get duplicated

* Inability to use custom templates for reports

I realize this is beta software (the 10th!) but these issues are simply quite unacceptable. I hope that the developers get these fixed, because the software has potential. For now I will use something else. I suggest others do likewise.
