I have a customer with two outstanding invoices, they have paid me for the newer invoice and I want to enter the payment against the invoice that they have paid.
I click apply payments, enter the date of the payment, enter the amount of the payment.
the amount is automatically applied to the oldest invoice,
I guess normally a customer will pay the oldest invoice first but when they don't how do I apply the payment to the correct invoice?
I've tried deleting the default entry to try entering the amount against the correct invoice but as soon as I click against the correct invoice the amount re-appears against the oldest invoice.
