When I was using the Winsim Simply Accounting Pro for payment, I picked two particular dates which were not in a row. It didn't let me to post. Now it keeps saying "Transaction is not balanced". How can I fix it?
In order to fix the issue, launch the program and go to Setup > Setting > Payables (or Vendors & expenses) > Linked account and link the proper prepayment account to this module. Check the official web page for further information.
