Hi @Mabaega,
First of all great job on the ZATCA connector, it’s very easy to use.
Now, I have just made a successful test integration for a client for ZATCA testing portal on a test business, however, now when I try to integrate with the Production environment on the live business, the relay takes me to this page:
Maybe it’s because it’s only one business per domain? Idk
I’m not sure how should I proceed.
Try checking the relay URL on your sales invoice.
It should be
There are no domain restrictions here, you can register all your businesses, even if they are from the same domain.
That
Somehow I missed /relay the other time around 
One more question, is there a way to upgrade a business connected to the testing environment to the live environment?
If not, it wouldn’t be a problem but I thought it’s good to know
Business details can be reset, but the Approved Invoice from the Simulation Environment must be cloned, and then deleted from the business data.
