How to create an order that only contains freight?

Hi,

does anyone know how to create an order that only contains freight charge?

i want to invoice a customer whose order had been returned and I don’t want to cover shipping again.

The initial products had been paid already, so I only need to invoice him for freight again.

as far as I can see, all orders are product based…

if anyone knows a solution, please let me know,

Thanks in advance,

best,

Andy
