I'm not receiving customer's replies to invoices we email out. The email address works fine when we test it with a non-QB email. Is there something else I need to do?

Welcome to the Community, @user02052.

Let me share information regarding the default email used when sending transactions.

Quickbooks Online utilizes the default email when sending transactions. With this, customers cannot respond to this message since it's only an internal email.

Moreover, you might want to review these resources to learn more about receiving customer payments and personalizing sales forms to improve business communication:
