Compatible Accounting Freeware?

I'm interested in finding good compatible accounting freeware (of least pretty cheap) for my shopping cart or plug-in for it.

Any ideas?

You will in no way find that type of software for free ( if it's worth a damn )
Here is one : http://www.opencart.com/index.php?route ... name=tclim (out dated a little). Ask the dev to make a current version if you are on anything after 1.5.2

It's a killer mod.

Yeah, I didn't think I would get that lucky. hehehe

Thanks for your suggestions here.
