How do I note the name or prospect or client with expense receipt?

A warm welcome to you, jerry. 

Let me walk you through the steps to note the client's name within the expense receipts using the memo section. To do so, here's how:

1. Go to Transactions, then select Receipts. 
2. Choose or upload a receipt where you want to add notes.
3. Click Review and add the necessary details. 
4. In the Memo section, enter your client's name.
5. Click Save and next.
6. After that, hit Create expense so that the receipt will go to the Review section. 

You can check this article: Email receipts and bills to QuickBooks Online. It contains guidance on how to email your expense receipts and bills to transfer them to QBO.
