Welcome, @dsanc1.
I hope your afternoon is going well. Let's get some insight into your request.
After looking into your question, there isn't a way to generate a statement on a cash basis. A statement is a document that outlines the transactions between a buyer and a seller, so there isn't a way to change this document or customize it. I want to ensure that your concerns are addressed. I'll personally submit feedback to our Product Developers so they can consider this feature in one of the upcoming updates.
Remember, I'm only a comment away if you need me. Enjoy the rest of your afternoon!
