You have added
ON A LARGE SCALE AND HAVE DONE FOR MANY YEARS
in order to disagree with my post
We are not discussing companies that do this on a LARGE SCALE we are discussing DROP SHIPPING
Devil is in the detail
In which your posts do not give the OP any valuable information on whether one is more viable than the other.
Other than telling the OP that drop-shippers do not have the same incentive to sell and market a product they do not hold in stock. Says who? Statistics? Facts?
These people are investing in your company every time they make a sale and have to then purchase it from yourself (the drop-shipping scheme). We are talking drop-shipping? So now we are talking about the people that decide to use it as a business model? These are the people you refer to with no incentive to sell a product because they don't hold it in stock? Previously you said "why would I want my item on your site blah blah"?
Drop-shippers (schemes) do not care who sells their product as long as it's sold quickly. They don't want the hassle of marketing each individual product, they put a photo, description & price and let others do the hard part for them.
If they have 1000 products and sell 5 a day at £5 profit per item. They make £25.
They want 1000 people, listing their 1000 items allowing them to sell 5 a day making the original manufacturer £5 profit on each item for quicker results. Now, I know you didn't need explaining the scenario but you are missing the point of what the OP is actually asking for here.
If anything, the OP will work just as hard to market that product as they are competing with many other people selling many of the same products. IF they use the same photos, descriptions and so on they will get the same results. IF they wanted to build and run a successful business through drop-shipping alone they will have to be that 1 step better with their marketing. Get samples and take their own photos. Write their own descriptions. Look further into each niche item. Offer something in addition which others dont.
"All companies SHOULD control their supply chain rigidly, not doing so kills your companies prospect of a long and profitable future."
Please explain? Do you mean eventually the number of people selling other peoples goods (those that do not hold or invest in stock) will disappear leaving drop-shipping schemes dead?
Maybe it's me missing something here?
