Tiered subscription management
Motivate your customers to buy more, for longer billing cycles. Offer them services with discounts, when they purchase more units or opt for services for a longer period.
Create discounts and coupons for the products you want, including fixed or flat discounts and coupon codes. Specify the discounts according to billing cycles, and have them auto-expired per date range.
Offer discounts when products are bundled and purchased together, or provide a free product as add-on when some product is purchased for longer billing cycle.
