Create sign up form?

Hi All,
I’m using this as a way to invoice clients who need items shipping.

I’m wondering if there is a way to set up a form so that a customer can go on to the website and “register” all their details, meaning that I don’t have to copy and paste from an email?

I can build a php script to do this and insert to the relevant db etc but if this is already possible then I’d rather use a pre-built function lol :slight_smile:

Any ideas?
