Sending invoices using GMAIL is NOT a solution.  Businesses know that a business email with their NAME not GMAIL domain is what makes them stand out as a professional in their field.  If Verizon uses QBO should they send out their bills from a GMAIL account???

This was a BASIC feature of the desktop product. Bring back the basics of sending an invoice with the business email as the return address using a subject that the customer can recognize (i.e. Invoice from [company name]).
