Debit Notes and Crecit Notes: Missing Total for Amount

is this possible to put Total under Amount column

purchase invoice show total

Sales invoice show total

Credit Notes missing total

You are not missing the totals for debit and credit notes. They are plainly visible in the Amount column. The reason they are presented differently from purchase and sales invoices is that only their full amount matters. No payments or receipts are ever recorded against them. Instead, their totals are applied to invoices or, if not specifically allocated to an invoice, to the supplier’s or customer’s overall subaccount balance in Accounts payable or Accounts receivable.

Purchase and sales invoices show two columns because it is important to know both the original invoice total and the remaining balance due.
