Hi @InventiveWD ,
I have tested in my demo store and figured out that We can’t check whether the company exists or not in the flow.
We can only pass the company name as a tag.
So, the alternative will be either we can add the company field in the customer register page.
Another way will be to create a order create webhook so that we can check all the conditions and add the tag accordingly.
Let me know if you need any assistance.
Thank you
