Prices in USD. Billing is processed by Paddle — they handle VAT/GST worldwide.
Stripe gives you one code per checkout, no stacking control, and coupon objects that sprawl. PromoStack is the promotion layer Stripe didn't build: stacking rules, idempotent redemption, and an API your whole team can reason about.
Voucherify starts around €600/mo — priced for enterprises. PromoStack is $29–79, built for indie hackers who hand-roll this today and ship the bugs with it.
Paddle is our merchant of record: they handle global VAT/GST on your subscription. Discounts themselves are applied pre-tax by your checkout — the way accountants expect.
