Hi there, @akhan-masaraty-s.
At this time, the structure of the invoice template for Saudi Arabia's Electronic Invoice Format and Regulations is not yet available in the system in QuickBooks Online (QBO).
I can see the importance of creating invoices that meets your tax agency's needs. For now, I recommend checking out for an add-on service (third-party application) that can integrate with QBO to comply with the new invoice regulation.
In the meantime, to learn more about handling invoices in QBO, see this article: Create invoices in QuickBooks Online.
You can also get more topics about your sales and customer transactions through this link: Manage Customers and income for QBO-International.
Keep me posted if you have any other concerns or follow-up questions about how invoices work. I'll be around to help, @akhan-masaraty-s.
