This is not the impression we want you to experience when sending invoices to your customers, @sleastackpreacher. Allow me to step in and assist you with your concern.
If the email address is invalid or there is a brief problem with the recipient's email server, the email bounces or fails to deliver. Verify that each of your customer accounts is linked to the correct email address. To ensure that clients receive their bills and pay you on time. You can follow these steps below to sort out this issue:
Step 1: Check the status of the sent invoice.
We are unable to identify which of many recipients the invoice was sent to and failed to reach. This indicates that the status will be Undeliverable if the invoice could not be sent to one of the three recipients. Here’s how to see when the invoice is undelivered to your customer:
- Go to Sales, then select All Sales or Invoice.
- In the Status column, you’ll see if the invoice is undelivered or sent.
Step 2: Make sure the customer’s email address is correct.
Ask the customer to check their junk or spam folders if their email address is accurate and they haven't received the invoice. You can also check your email address in QuickBooks Online which might be causing the issue.
- Go to Customer & leads, then select Customers.
- Select the customer who didn’t receive the invoice.
- Select Edit.
- Check the email address and edit it if needed.
- Resend the invoice.
