Consignment is an agreement between the consignor(company) 
and the consignee(customer), that the consignor will send 
goods to the consignee and the consignee will pay only 
after selling or consuming the goods. The goods which are 
not consumed will be taken back by the consignor.

Steps involved:
Consignment fill up
Consignment issue
Consignment returns
Consignment pick up.

Sorry Rakesh, Consignment is an agreement between the 
consignor(company) the consignee(Agent)and not a customer.
Steps invloved -
1)Consignment Fill-up - The Company send material to the 
Agent.Ownership of the material remains with company.
2)Consignment Issue - Agent sells the material to the 
customer.
3)Consignment Pick-Up - If material is not been sold by 
agent then the Company takes the material back from agent.
4)Consignment Retun - Customer sends damaged material back 
to agent, and agent sends it to company.

Us, I disagree with you. 

Sorry Rakesh, I accidentally marked your answer as wrong. I 
think what you are saying is right. Consignment process is 
an agreement between the company and the customer or 
consignor and the consignee. If there is an agent in 
between, then he is more likely called an intermediate 
consignee. What I know is the intermediate consignee then 
becomes the ship-to to the company selling/sending the 
goods requested by the customer.
