We'll keep working to improve your experience using QBO, @Vespucci. 

Currently, the SKU column will not print on a PO regardless on the number of pages. I suggest adding the SKU information to the Description field so it appears on the printed purchase order. You can check out the screenshot below for your future reference. 

Please know that we're taking note of all your requests. I'd make sure to pass these along to our Product Development Team. These help us improve our products and services. To help you stay current on all the program news and updates, see this helpful link: QBO Blog. 

For more details about how purchase order works for your business, you can read through this article: How To Use Purchase Order. I'd suggest running any PO reports to help keep track of your vendor balances. 

Keep me in the loop if there's anything else you need. Have an awesome day.
