Assalamu alaikum.
I hope you and your family are safe. I want to share a situation.
Sometimes some wholesalers show products (cloth. i.e not agricultural) from the weavers directly. That is a wholesaler W is showing you a product which is still at the hand of the manufacturer M. Here several cases can happen.

M and W are business partner. That is, M produces the products and W sells them to the customer. So, W shows the product images to Customer C. But the products are still at M’s house. When C choose any product then, W bring the products to his shop and When C pays him (W), he sends the product to C’s address. ( i know this is ok. is my knowledge correct? )

M is actually owned by W. That is, M produces the products and W has hired him for making the products. So, W shows the product images to Customer C. But the products are still at M’s house. When C choose any product then, W bring the products to his shop and When C pays him (W), he sends the product to C’s address. ( i know this is ok. is my knowledge correct? )

M is not a direct partner of W. Rather M has manyyyy buyers like W. W shows the product of M to customer C. When C likes the product (cloth) then W asks M to keep the product aside or book the product and then brings the product to his(W) shop (if the product is available) by paying M his payment.Then, W ask C to pay the payment and after the payment is done the product is shipped to C.

And W and M complete their own payment according to their dealings.

When C likes the product (cloth) then W asks M to keep the product aside or book the product and then asks C to do the payment.After C does the payment, W pays M and asks M to send the product to his shop.And after that M sends the product to C.C knows that the product actually belongs to M. And W is just acting as a source.

And W is just acting as a source.
In all the cases obviously price is determined when the product was shown to C and M has stipulated the price to C including all his personal profits (in the cases where M and W are not direct partner.)
As per my findings number 15 are ok. Is my finding correct? And what about number 6?
If any process is not correct then what is the way to do it properly? (please ask me if I need to make any point clear.)
