Is there a way to get read receipt from the invoices I email? So I can see if my customer read them?

I'm here to help share information about invoices, @providencewaterh.

As of the moment, there isn't an integrated way to get a receipt showing your customers have viewed the invoices after sending them. Instead, invoices in QuickBooks Online will be marked as paid once customers already made the payment.

While the option is not yet available, I recommend letting our product developers know about this request by sending feedback. You can do so by following the steps below:

1. Go to the Gear icon.
2. Under PROFILE, select Feedback.
3. Enter a few describing how this receipt for invoices can help your business tracking and reporting needs.
4. Select Next.
5. Click Skip and send message.

I'm adding this reference so you're able to track the status of your request as well as the latest updates from our developer team: Customer Feedback for QuickBooks Online.

It'll always be my pleasure to help if you've got other questions besides QuickBooks invoicing. Use the Reply button and leave your comment below so that I can assist you further.
