Depending on market needs and economic factors, there is a certain degree of flexibility in whether to restock after the inventory is sold out. If the product is seasonal or a temporary hot-selling product, it is not necessary to restock immediately after it is sold out, and you can wait for the next peak in demand to restock. However, if the product is a long-term bestseller or a necessity that customers often buy, it is recommended to restock in time to ensure stable sales and customer satisfaction. In addition, after the inventory is sold out, it is also necessary to evaluate the market demand and competition situation and make a reasonable decision on whether to restock.
