Now, you can create coupons for external use and share them with your clients! For use with packages and products, each coupon can be denoted as an internal coupon (only can be manually applied to invoices) or external coupon (can be shared with clients!) 

When used externally, clients can redeem their coupon at the point of sale and apply the discount to their purchase.

Coupons can be fixed amounts or a percentage discount with the customization on how many times they can be used, plus their expiration date.
