I have Quickbooks Professional Services Premier Industry Edition. When I try to enter Figures with period, in the journal general entries, the figure is not accepted and I get a message that there is an unidentified character!

I don't use Quickbooks, but my first guess is that it's automatically set to do two decimal places.

So if you had $143.16, you'd enter 14316 and the decimal is automatically put in two places from the right.

If you had $100, you'd actually have to enter 10000, so that it comes out 100.00, again automatically entering the decimal two places from the right.

Assuming that's the issue, there may be a setting to change it. I know Peachtree has a setting like that. Check out the options.
