Send invoice via WhatssApp

Does the premium version support sending invoices to customers via WhatsApp? If not, can this be customized?

I would like to add the product description meta to the invoice, right under the product name.

I would also like to add stock status to the invoice. The available stock status meta only shows “in stock”. I want to show the total price of the outstanding inventory.
e.g Total outstanding stock: $5000
(note: $5000 is gotten from [unit price] X [remaining stock])
