Thanks for checking on this, @BobSaville,

Payment notifications for QuickBooks Payments will be sent to the default email address entered on the Contact Information section. If you haven't received any messages when a customer pays online, check your account settings if it has the correct email address in it.

Here's how:

1. Sign in to the Merchant Service Center.
2. Go to the Account tab then Account Profile.
3. In the Contact Information section, click Edit.
4. Update the email address then click Save. 

The steps to update your information in the Merchant Service Center is shown in this Community guide: Change business, bank account, or contact information in the Merchant Service Center.

If you have the correct email there and still not getting any  payment updates, I recommend getting in touch with our Payments Team. There they can help check why you're not getting any notifications from us.

Here's how to contact Support: QuickBooks Online with Payments & Merchant Service Center
