The reason you want to return Peachtree and get your money back, and then go out and buy QuickBooks is because if you make a mistake in Peachtree you have to enter an offsetting entry. This is such a pain, you have no idea.
If you make a mistake in QuickBooks, you can edit it, merge it, or can even delete it!
Yes, QuickBooks is the first accounting software that has ever allowed the user to do deletes. I've had clients who upgraded from old-school accounting software and used to joke, "I don't do deletes" They did eventually, of course, but at first, they wanted me to do the risky stuff.
It's a godsend that QB does all that. So much of my work is going in behind other people. We can go over your business model, set it up correctly, change stuff en masse, and clean up the problems very quickly. No data has to be entered again to do all that! I can clean up what's there, usually. Sometimes there's been fraud, where I have to start from scratch. It's very forgiving software.
Also, if you're asking this question, you're going to want to read my book, "Radical Accounting". It's such a cheap way to ramp up your expertise. You'll see that I've been there, done that, and wish you a better time of it than I had, ha, ha.
