Thanks for chiming in on this thread, @Snowboarder. I'll be sharing some information about the packing slip in QuickBooks Online (QBO).

I understand how beneficial it is for your business to print the purchase order with the SKU column. However, the option to include the SKU when printing the packing slip is unavailable. 

As a workaround, you can enter the SKU in the Description column when creating an invoice or sales receipt transaction. 

If you haven't turned on the SKU feature in QuickBooks Online, just follow the steps below to enable it:

1. Go to the Gear icon, and select Account and Settings.
2. Choose the Sales tab.
3. Enable the Show SKU column under the Products and services section.
4. Select Save, then Done.
