Hi @slyc,
The coupon field is shown automatically on the cart and checkout pages if you’ve enabled coupons at WooCommerce → Settings → General > Enable coupons.
As for the referrals, kindly check whether this plugin can meet your needs: https://woocommerce.com/products/referral-system-for-woocommerce/
The only catch is that the referral link is accessible from the customer’s My Account page, as explained in the documentation.
