The reason you're having a hard time is because you feel like you "know" Quicken and hare having a learning curve with QuickBooks.
I have to use Quicken for my investments, and it took me 1.5 years to get up to speed, and I still can't it to give me ROI the way I want! Arragh!
But there isn't a single thing I can't do or fix on QuickBooks. Alot of my work is going in behind people who made it look like rocket science because they weren't very good at it themselves, so they couldn't think how to make it simple for the business owner. It's really very simple, and simpler still if you have a smaller business. I use it for my personal finances. I use it for a CEO who just wants me to type in his paychecks and check register at year end. Actually, his wife who hired me, so he could get his taxes in on time.
I recommend you keep hacking away with QuickBooks. Even if you're making mistakes now, you can fix them. If you can't afford to hire trainers, there are other ways to learn. My book is an accounting book but accounting is half the battle. It speaks your language and you'll see why you'll want to be able to add assets, and liabilites now, and maybe more in the future. You can have friends show you what they know. You can barter. There are QB books in the library. And it's not as if you have to be perfect at QuickBooks today. Once again, people come to me pulling their hair out, and get almost angry when they find out it's as easy as they thought it should be.
You can do time tracking in QB, which is awesome for most small business owners, and you can produce financial reports that everyone in the business world approves of. Say you want to get an SBA loan someday, or take on a business partner, or sell your business, or whatever great things the future may hold for you.
Quicken H&B is basically a glorified check register. While your business may be simple now, if you stay with it, you'll never have to learn new software again, no matter how little or how much you grow your business.
I'm suffering ACT! software right now, and I'm doing the same thing I'm advising you to do. It's a pain and an investment, and I'd love to back out, but I know moving forward is the right thing to do.
