If you are looking for an invoicing and time-tracking app that has Calendar synchronization (for those that like to track jobs with notes in Calendar, like me, and for those that don't like subscription-based web products) try OfficeTime. I just moved over to it from iBiz and I'm liking it.

I believe IGG should just focus on iBank, which I have not tried and will not, while staying away from more serious software development that is clearly beyond their coding capabilities. The software is in a nutshell:

UNINTUITIVE
AS BUGGY AS WINDOWS 3.1
AMATEURISH AT BEST

We almost lost a client because of a series of bad invoices were issued and the program did not calculate discount properly (a pretty simple task). We have had to find work-arounds for a lot of pretty basic tasks. The only reason why we chose iBiz was their ability to pull information from iCal; even that it DOES NOT DO WELL and it is quite temperamental. PLEASE DO NOT BUY IT if you are a consultant. I do not know which software I will use from now on but to be sure I will need to go back to Excel until something decent is released.

Just updating my review to reflect the ongoing improvements to iBiz and to counter-balance the odd negative ratings iBiz has received here lately. I still find iBiz to be the best program in this category since it easily allows me to synchronize work log data between iCal and iBiz... so I can record time and work events in iCal (individual calendars for each client) and synch these directly with iBiz (specifying whatever date range I prefer) for billing. Other programs I have tried are more limiting in how they allow data synchronization with iCal, especially in selecting specific client work log events and date ranges.

IBIZ 4.1.4 LEAKS MEMORY LIKE A SIEVE. Why do the 4.1.4 notes say that the leak has been fixed? I upgraded recently from 2.x after many years and am now being forced to revamp my entire time tracking scenario because of this SERIOUS BUG. I just sit here in Activity Monitor and watch 1-2 MB leak every minute, and 1-3 MB every time I start a timer. THIS IS UNACCEPTABLE. And worse, why did they lie about fixing the leak in version 4.1.4 when it is leaking like crazy? This is devious. And the company has closed their forums in favor of a skimpy "knowledge base."

While I can understand that some people prefer the old interface of earlier versions (I was of the same opinion originally) I have readily adapted to the interface on the new version and better understand the reasons for the changes. Users of the old versions just need to give the new version a try for bit. This program still works best out of all similar programs I have found and tried via MacUpdate. It works perfectly within my work flow and allows me to track time either at my workstation or away at a job site (via events transcribed into iCal on my other devices.) The ability to synchronize calendars within specific time periods and the flexibility of creating very customized invoices makes this superior to other such time tracking/invoicing programs.

Version 2.5 will not start on 10.3.9. Interface needs a major rethink, in my opinion. I have stopped using it as of a few months ago and have gone to a Filemaker solution, built from scratch. I have also been looking into iRatchet, which I think has great potential and the developer is really great.
