Thank you for mailing your question to our mailing list.
I'll provide you with the answer as to how I understand your
situation from the screenshots you sent:
First, you created a sales invoice (AR) which was given
number 4. Then you discovered the numbers in the invoice were
incorrect, so you clicked the VOID button on the invoice. You
expected the invoice to be removed from the list of "open"
(unpaid) AR items. However, from your screenshots, I see they
are still there.
(Is that what happened?)
If that's what happened, the following is the (not too
great) solution: If you go to the Cash -> Receipts screen
and select the customer of these invoices 4 and 4-VOID, you
end up in a screen which allows you to enter a payment. Now,
in that screen select the invoices 4 and 4-VOID. The total of
the payment should indicate "0" (zero). Then, select an
account and a payment date and click POST.
The result is that you've used the negative AR amount from
invoice 4-VOID to close the positive amount of invoice 4.
There's a payment in the system, but the payment is net-zero.
If you use an otherwise-unused account to record the
transaction, there will be nothing in the books and the
account will show a zero-balance both before and after the
Hope that helps!
