What problem is REALLY bugging you? 
jcnnghm: Quickbooks.  Quickbooks is the single worst piece of software that I have ever had to deal with on a regular basis.  I want to be able to reliably pull in all the financial transactions that occur for my company, and categorize them as quickly as possible.  Quickbooks does this, but it fails on the reliably, all, and quickly aspects.I also need to be able to import invoicing information from my billing software, and match that to bank deposits and credit card settlements.
