1. Stocking cycle time. Stocking cycle time is affected by factors such as product sales, purchase time, and transportation logistics time. Know your actual inventory and calculate the daily sales of the product (usually one week, sellers can calculate one week, ten days, or one month based on their own product details). According to the product's previous sales and daily sales, set an approximate number of days to start stocking. If your product is hot-selling, then you have to ensure that there is sufficient inventory sales in the FBA warehouse, such as one month or ten days of inventory sales. In addition, you must also consider the delivery time, purchase time, product warehouse release time, etc. Comprehensive consideration: inventory sales + transportation logistics time + purchase time + warehouse release time. The formula calculation is dead, and sellers must optimize the calculation according to their specific situation. Every time you prepare and deliver goods, you can count and write it down as a reference to save your time.

2. Multiple delivery methods coexist. When the inventory products are almost sold out, it is recommended that sellers use international express to prepare the stock. International express can usually be checked in 4-7 days. Although the transportation fee is a bit more expensive, it can ensure that your listing ranking will not drop and the inventory will not be out of stock. When the product inventory is sufficient, you can choose dedicated line transportation and air cargo to prepare the stock. The price of dedicated line transportation is relatively cost-effective. Air cargo can transport a large amount of goods, and the price is also cost-effective compared to international express. Just after the stock is ready, the inventory can be guaranteed. You can choose international shipping to prepare for the next product warehouse. International shipping can usually be checked in about 1 month, with large quantity and low price.

3. Prepare the stock in advance. Anyone who needs to use the warehouse to store and sell their products must be prepared to prepare the stock in advance. This is an eternal truth. There is no need to wait until the inventory is insufficient or gone before preparing the stock. During the hot season, the logistics will also be affected. Problems such as access restriction and warehouse queuing will occur. The logistics speed at this time will be relatively slower. Usually, the stock is prepared once a week in advance. At this time, it is best to prepare the stock two weeks in advance.
