If you are struggling with GST a (VAT or Sales Tax) you really need to spend some time on Accounting Made Easy. IT will cost you $25 and a few hours. If you don't, you will lose money to your revenue authorities.
I have been using TC for years. Love it. Recently had to set up new for my kids in AUS. Problem, when I put GST in on bank account. Does not want to post,receive error message that cannot use 950 accounts. Always worked previously. Please advise.
