Product labeling is to write and display information about a product’s packaging. You can print and paste labels to your products, then you can scan the label when packing products to know if you pack the correct item.
When you sell multiple different products, you need to reorganize your warehouse and store your products in different places. You can purchase shelves and put different products on different shelves. It can help you to pick items easily and you don’t have to take time searching items from the whole warehouse.
After you pick items from the shelves, it is a good idea to check the orders info and picked products again before you pack them to parcel. It adds another layer of security and verification and ensures that you don’t pack the incorrect items. If the items are incorrect, you can recheck it and change it from warehouse.
You need to make sure there is enough stock in your warehouse when you have orders. You can count stock and replenish stock when there is low stock or no stock. You can also use other 3rd-party tools to manage your stock, for example, BigSeller. It will remind you in Dashboard when there is no stock or low stock.
Here, I suggest a tool called BigSeller, you can use it to scan your package and products before packing to inspect if you packed the correct items. After you can scan products, you will know if the product is correct. And it will remind you when the product is incorrect or the quantity is incorrect. What you need to do is register BigSeller account and use the scanner to scan the package and products.
