The Stock Progress Bar Addon has a dedicated setting option that will be available after turning on the addon to change the text of Total Sold Count, Available Item Count.
Enable on Simple Products
For enabling the stock progress bar on s Single product page, we have to enable stock management at the product level and add a specific quantity of the product.
Enable on Variable Products
You can also enable the stock progress bar for variable products. Don’t worry it’s not as hard as it sounds. You just need to manage stock at the variation level and add the maximum quantity for all of the variations.
