Hi there, jgconstruction. Let me provide additional steps in emailing your customers' invoices and route you to our support team to check your account.
Please verify the email address for accuracy. If it is correct, try sending the email to yourself. If you receive it, the issue might be on your customer’s end. In that case, you can request an alternative email address and send it there.
However, if you're unable to receive the email, I recommend contacting our QBSE support team. Our team can check your account to determine why you cannot send your invoice, create a case, and have this investigated.
Here's how:
Log in to your QBSE account, then go to (?) Help.
In the Type or ask something field, enter your inquiry.
Press Enter on your keyboard to send it.
