How can I set up customer-paid shipping options?

Hello,

I have a question about shipping. How can I configure my shipping settings to “my customer will pay the shipment”. In shipping setting I cannot see this option.

I do not have fixed price for shipping. It depends on the quantity and the area. Sometimes I use cargo and sometimes local warehouse companies to send my orders and always customer will pay shipment costs.

Basically I would like set up my shipping settings to “customer will pay shipment cost”.
