By default, Customers won’t find an easy access to enter their Coupon Code in WooCommerce. The text “Have a coupon? Click here to enter your code.” is visible but there is no option to enter Coupon Code directly. Customers need to first click on that message, and then the box appears.

Add the above code to your theme functions so that, the Coupon Code box will always appear in the expanded view. Customers can easily find that box and will be able to enter their coupon codes. There isn’t any chance that customers will miss to avail discounts on your site.
