My sales invoices are not being displayed in the Export grid

Question/Problem 

My sales invoices are not being displayed in the Export grid for exporting to Quickbooks or Xero.

Resolution/Solution 

Invoices will not appear in the Export grid until they have been issued from within [Sales Invoice Manager] .

Once issued, they will appear within a few seconds  although you may need to click Refresh if the Export screen was already open.
