Hook to disable invoice creation during ShoppingCartCheckout for certain clients to minimise domain transfer invoices

[Mark]

Good morning ☀️,

Certain clients place multiple domain transfer orders in a day.  Sometimes 20 orders.
These type of clients are complaining about the amount of invoices they get after placing the orders.

I'm thinking about creating a hook that disables the creation of an invoice upon ordering for certain clients or client groups.
It would mimic disabling "Generate Invoice" when manually placing an order as Admin.

With the above case of 20 orders in a day in mind I think that a - single - invoice for those orders will be generated upon the next run of 'do --CreateInvoices'. 

p.s. This is not about renewal invoices; we already provide these type of customers with a single monthly invoice.

What are your thoughts about this idea? I.e. would this be a bad idea?

Regards,

Mark
