What setting should i apply to help me see customers balance in the payments receipts

I can share some information about checking customer balances in payment receipts, Evans. 

When creating an invoice and processing a receive payment transaction, the amount shown on the payment receipt is the current balance before applying the payment. The option to add the customer balance after the payment is currently unavailable. That would be a great addition to the current features that we have, so I'll take note of it.

Here's more information about recording a partial or full payment for your invoices: Record invoice payments in QuickBooks Online. It'll also guide you with editing or deleting, voiding or deleting, and applying a credit note to it. 

You may also consider sending your customers a customer statement. It'll show you summaries of your invoices, payments, credits, and balances. Refer to this article for detailed guidance: Create and send customer statements in QuickBooks Online.

Let me know if you have further questions about receipts. I'm always glad to help in any way I can. Have a great rest of the day!
