So I have now ensured the setup is correct and the GST is no longer going into my costs. We have never made changes to this function and are wondering if this setting could have changed with an update and or when Softrak purchased the purchase orders. This has now been understating our income since the problem started. After we have manually figured out what gst we should have paid, how do I get the GST out of my inventory items, so that my future income statements are correct?? Is there a way to find out exactly when this began. this is a nightmare!! please help!!
