Hi there, @lbudiman1.

I can see the importance of adding the SKU when printing purchase orders in QuickBooks Online. I'm here to share with you another workaround to get it printed.

At this time, you can temporarily add the SKU details under the Description column so you can include them when printing your transaction.

Here's how:

1. On the Purchase Order window, add the SKU numbers under the Description column.
2. Tap on the Print button to print the transaction.
3. The SKUs are added under the Description section.

I've added these screenshots for your visual references.

Rest assured our engineers are working nonstop to deliver the best experiences for all QuickBooks users. Hopefully, the option to print the numbers directly from the SKU column will be available real soon.

For the time being, I would recommend checking out our blog to stay current with the latest QuickBooks news and feature enhancements. Here's the link: The QuickBooks Blog.
