Hi there! Welcome to the Seller Community. 🙂

I just want to be sure I am answering your question accurately - are you wanting to allow customers to leave a review for online store purchases as well as appointments like you can in the Point of Sale app after a sale has been made?

If that's the case, then at this time, we do not have the ability for customers to leave feedback for the online store. I do think it's a great request and could really help sellers like yourself grow your business more, so I have shared this feature request with our Development Team for tracking! 

Also, please let me know if you have any other questions!
