When a customer pays an invoice with fastrack the GST will show up as 'out of scope' and so doesn't get recorded. It's making accounts inaccurate

Hi marie.taylormade,

If the transaction is under the For Review in Banking page, you should be able to select a GST code to categorise the transaction prior to adding or matching them. If the transaction has been added In QuickBooks you'll have to locate and open the transaction first and then edit the GST code applied to the transaction, and then click on Save.

You can also check your GST codes and setup by going to your GST tab, selecting Settings, then Edit rates.

Here's also a detailed article to learn more about Categorise and match online bank transactions in QuickBooks Online.
