You can offer promotional (promo) codes or coupons to customers to incentivize subscriptions.
To add a promo code, you must first add the promo code and length of the promo code to GeoTab. Consult your GeoTab website for more details.
Once the promotion code has been added to GeoTab, you need to add the identical code in Stax Bill.
To set up the coupon codes in Stax Bill, see Creating Coupons.
Once the coupon code is added to both platforms, Stax Bill will be able to validate the coupon when received from the GeoTab integration and apply it to the subscription.
