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