With the Charge theme, you can keep your customers informed about the right number of products in stock. This will create a positive shopping experience and prevent losing customers because of a lack of consistent information about product availability.
To use the Manage stock theme's feature, you have to enable the Track quantity checkbox in Shopify Product first. That will help you to manage the inventory of each product variant in the Shopify Product configurations.
To notify the customers about the only X-product left in the inventory stock you have to enter a quantity that will start calculating the stock from. Go to the Charge theme Product page configuration and find the block Manage Stock.
Note: The block is disabled by default. You should enable it and set the stock counter value.
For example, stock counter = 10 - if a product or product variant will have less qty than the Threshold value the stock label will show “Only X left”. In another way, the label will text “In stock X left”. The label Out of stock will inform the customers about the out-of-inventory stock product. When a product is sold, the system will automatically change the inventory status.
Note: The Manage stock block can be shown anywhere in the Product information section. You can simply drag and drop this block to the place you want to show the Stock status labels.
