Backorders on invoice and packing list using QuickBooks Online Advance

We can use a third-party application to migrate your previous invoices and packing slips to QuickBooks Online, @Shariekp. 

Since we're unable to suggest a specific application, I'll route it to the QuickBooks App Center. Then, you can choose an app in the categories section or find them in the Seach bar.

1. On the left pane, go to Apps.
2. Next, click Find Apps.
3. You can choose them in the Categories. 
4. Lastly, find them in the Search bar, and enter or type the keyword.

You can also visit this link for additional references: QuickBooks App Center.
