What do you mean by joining? Does joining require no inventory?
Joining is that the headquarters is responsible for the support and franchise of trademarks and technologies. Whether there is inventory depends on the nature of the product, and the franchise contract will clearly indicate the corresponding responsibilities and obligations of both parties. Generally, they will purchase their own goods, and some allow exchange or return unsalable! In short, when the headquarters joins, everything is subject to the contract! I hope I can help you! Ask for adoption!
