All recurring transactions, (invoices, bills, expenses etc.) are pulled and can be used as projections in your forecast.
All you need to do is:
1 - Go to the Projections screen (see image)
2 - Click "More settings"
3 - Make sure "Include recurring transactions from QuickBooks/Xero" option is set to "Include in the forecast" (see image)
That's it! Now you can see recurring transaction based projections. They will have 'QuickBooks' or 'Xero' in the SOURCE column.
