Dan Murphy's don't have a B2B marketplace & there is no mention anywhere of their intention to launch a B2B marketplace.
They have recently launched a B2B sales model targeting Corporates & Events. There is a catch though buying from Dan Murphy's as a business customer - you are not allowed to resell for tax reasons & the products are for drinking only. Retail limits also apply to orders. So the platform is for businesses to buy alcohol for in-house functions only.

Endeavour have a B2C marketplace that has been active for a number of years. There is no mention of the commission amount but their other company Langton's charges 20% commission with payment in 7 days. Endeavour don't hold any customer stock & rely on suppliers to pick, pack & send the packages. They operate a dropship model. Endeavour have a delivery division that is the exclusive delivery fleet for Dan Murphy's & BWS.

Does Endeavour Marketplace hold stock for suppliers?
How much do I have to pay?Are there restrictions on what I can sell?Will my products be visible in stores?How does shipping work?Do you sell products from overseas?Dan Murphy's B2C marketplace has minimal if any control of delivery as it is done independently via the suppliers, hence, the below average customer feedback. If the supplier takes a few days to pick, pack & send the packages then the entire process is delayed. If the supplier is interstate then additional delivery delays are experienced by the customers.
