I do wholesale of clothes. Have to set up invoice. I need to have in one line: article - XS - S - M - L - XL - XXL - price p.p - total . Does anybody know how to do this?

Hello there, @gernot-gernotwun.

In QuickBooks Online (QBO), we can create an item one at a time. This way, we can put the item per size.

Here's how:

1. Go to the Gear icon.
2. Under "Lists," choose "Products and services."
3. Click New.
4. Choose Inventory.
5. Enter the Name, SKU, Category, and other information needed.
6. Once done, hit Save and close. 

Additionally, you can customize your invoices to add information that matters most to your business. This way, you can create an attractive and professional-looking sales form. To learn more about it, you can refer to this article: Customize invoices, estimates, and sales receipts in QuickBooks Online.

Please let me know if you have other concerns. I'm just around to help.

You need to have an additional app with the matrix inventory feature to integrate with QBO.
