We really need this option added. When we were using Gmail, everything worked fine, but since switching to Microsoft, we've had multiple customers report that they aren't receiving our estimates and invoices. This is leading to late payments and making us appear disorganized.
Please consider adding this to the funnel. I believe it's more needed and wanted than it may seem. Most users won’t go through five steps to request a fix, they’ll just continue using a workaround, especially when they’re not the ones paying for the service.

Quickbooks desktop had the invoices come from our business address. The online version should be able to work the same. Customers are telling me they aren't getting the invoices. It appears they are being sent to the junk folder.

The reason this is critical for us is that our invoices are sent to an Accounts Payable system. These systems require us to register our organization. I can't register our organization with a 3rd party email address. Our client might have a dozen vendors invoicing through Quickbooks and the system can't recognize which organization the invoice comes from when the "From" email has an intuit/quickbooks email domain.

QB Desktop has this handled properly.
Emails going to customers from a Quickbooks default address causes several issues:
1. Invoice goes to SPAM
2. If we type in the recipient's email incorrectly, we will never receive the error message because it will return to QB who will not notify us.
3. The option of using a GMAIL account as the 'from address' is COMPLETELY unprofessional. Businesses use their name as their email, not GMAIL. That makes the client and their server look for another email address to receive correspondence and may still end up in SPAM as a result.
4. The invoice is NOT in our business email as a sent item so that it can be re-sent to the customer in the event that they need to see when it was originally sent.
