Good day, @samibasfar1. Let me share some details about the new implementation of e-invoicing in Saudi Arabia.
I can see the importance of using an invoice that's meeting the new requirements for electronic invoicing and VAT regulations in Saudi Arabia. However, the structure of the specified invoice template isn't yet available in the system.
For now, I'd recommend checking for an add-on service that you can integrate with QuickBooks Online to comply with the new invoice regulation. Know that QuickBooks Online always aims to be compliant with the rules of the tax agencies, and we find ways to cope with your business's needs.
While waiting for updates, here's how you can learn more about handling invoices in QBO: 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.
Let me know if you have follow-up concerns about this or should you need anything else. I'll be around to help, @samibasfar1.
