I've not used QuickBooks, so if you are committed to using a pre-packaged solution for your invoicing, this answer won't be helpful to you.

But, it strikes me that it would not be too difficult to create a simple invoicing system in Excel that did rudimentary accounting along with printing the invoices.

Of course, I am an Excel geek thoroughly trapped in the "If your only tool is a hammer, everything looks like a nail" paradigm, and would no doubt enjoy the challenge of setting up such a system a lot more than you might. Unless you really enjoy tinkering and expanding your Excel knowledge, $10 a month would be your better option.
