see a customer's total sales and payment amount

Hello experts

My client asked us for a customized customer invoice which includes Total Sales Amounts, Total Payment and the Customer Balances.

I found the standard Customer Balance List report and it shows Debit Balance - Credit Balance = Total Customer Balances,  and I think this is not my client wants. For example, Credit Balances not only include the customer payment, but also include canceled sales amounts.

As I mentioned above, In the newly customized report, I want to include

1) Total Sales amount = Customer Sales - canceled Sales

2) Total Payment amount

3) Customer Balance= 1) - 2)

and I want to know where can I bring those amount.

Can you please let me know the AOT path for those data ?

Thank you
