All of our orders from an ecommerce platform come into QB as invoices. Is there a way to automatically send those invoices to the customer?

You'll need to manually send those invoices to your customer, Aturner. Let me share some information about this process.

Currently, QuickBooks Online doesn't have the ability to automatically send invoices to your customer. As a workaround, you'll have to use the Batch action to bulk send these data. To do so, here's how:

1. Open your QuickBooks account.
2. Go to Sales, then Invoices. 
3. Tick all the invoices you want to send.
4. Head to the Batch action dropdown, then Send. If your customer doesn't have any email attached to their profile, a window will prompt you to add their emails. 
5. Once done, you can tick the Save email addresses for future use, then Send.

Moreover, we strive to provide our customers with the best experience while using our product. With that, you can send this suggestion to our engineering team so they can consider adding the option to automatically send invoices to your customer in the following QBO updates.

To send one, here's how:

1. Go to the Gear icon menu at the top, then select Feedback.
2. Enter your comments or product suggestions.
3. Click Next to submit feedback.

You can use a 3rd party app to do so.
