Stripe Billing errorStripe: coupon_expired

Rather not fix it yourself? Stripe Billing Fix and Setup handles it at a fixed price, agreed before work starts.

Why Stripe refuses the coupon, and the fix

1. 01

   The redeem_by date has passed

   “Either create a new coupon, or use an existing one that’s valid.” Stripe, Error codes (coupon_expired)

   A launch coupon with an end date stops working on that date. Make a new one for the next offer instead of reusing the old ID.

   const coupon = await stripe.coupons.create({
     percent_off: 20,
     duration: 'once',
     redeem_by: Math.floor(new Date('2026-12-31').getTime() / 1000),
   });

2. 02

   The code still sits in the app

   “The latest date at which you can apply this coupon to customers.” Stripe, Coupons (redeem_by)

   A coupon ID hard-coded in a Checkout call or a pricing page link keeps failing after it ends. Read the current offer from config, and check the coupon before creating the session.

3. 03

   The redemption limit may be the real cause

   “Maximum number of times a coupon can be redeemed across all customers.” Stripe, Coupons (max_redemptions)

   A coupon that has hit max_redemptions stops applying too, though Stripe may report it with a different message. max_redemptions counts every use, by any customer, including promotion codes on that coupon. Raise the limit on a new coupon, or use per-code limits on promotion codes.

4. 04

   Existing customers keep a forever coupon

   “New customers can’t apply the coupon after the expiration date.” Stripe, Coupons (redemption limits)

   Also check: expiry only stops new uses. A customer who already has a forever coupon keeps the discount, so plan price changes with that in mind.

Checked against the vendor’s docs on November 9, 2026: Stripe docs: Error codes; Stripe docs: Coupons and promotion codes.
