How can we improve WHMCS?

Hello,
I am writing to you to present the following suggestion, which I believe would make accounting easier for the companies that use your system.
The idea is that invoices should not be generated automatically when an order is placed. This functionality exists when creating an order manually from the admin panel, but not when the order is placed by a client. I assume that the logic is already in place and written, so it should not be difficult to add.
This way, the administrator can create the invoice only after approving the order, which would significantly reduce the issuance of invalid invoices.
