The procedure is very common, and the license is ok.
This is not easy to open. First, you must contact the local milk distributor. Finally, someone inside knows the cif price. Otherwise, you should reach an agreement with the dealer. When there is an activity in the supermarket, it is best to sign a contract to support your activity. Otherwise, your shop will not survive. The profit of buffalo milk should be around 17%, and that of low-temperature yogurt should be around 26 or 7%.
The most important thing is the method of settlement, and the goods are taken first and then settled. If the local dealer looks strong, there is a good way to cure him-cargo smuggling.
Ask me if you don't know.
good luck
