Hi there, Malay Shah.

Currently, we're unable to automatically send an email receipt once an invoice is paid. You'll have to manually send an email to your customer confirming the payment. Please follow the steps provided by my colleague above.

I can see the importance of this feature into your business. Rest assured, I'll take note of the feedback and submit this along to our Product Development team to help improve your experience.

I just wanted you to know that providing the best possible solutions to our customers is of our main goals here in the Community.

I recommend visiting our QuickBooks Blog site. This is where we share recent happenings and future developments, such as updates to newly added features.

Please leave a comment if there's anything else I can do for you. I'll be here to help you. Have a nice day!
