Hello,
I need a feature/module to automatically add customers to specific customer's groups.
In my shop, during the order check-out (when the customer needs to fill the form related to shipping and invoicing address), I have added a field named "VAT number".
Then, I have created a customer's group named "companies".
Now, I need to automatically add to the group named "companies" all the customers that specify a VAT number in that form.
Is there anyone that knows how to do it?
Thank you in advance for your support.
