Hello.
I have a lots of clients with
Name: S.A.R.L
And this is not a good way to force the client to change the name or the lastname.
And if you use your prestashop with some market places (ebay for example) some times you have just one name for example 365.shop
It is not the best way to force the client to choose what you want. You have to accept what the client wants
