Peace be upon you all.
A suggestion
that would be very useful is to group all payments collected from the customer onto a single line in the invoice titled "Collected" if it's a sales invoice, or "Payment" if it's a purchase invoice. This would be very practical, and from the invoice, both we and the customer could see the total payments collected and the remaining balance. Those who want a detailed breakdown of payments can find it in the account statement.@lubos
