Last updated 25 April 2026
Steps
- Find your subscription confirmation email
- Click Manage Subscription β opens the Stripe Customer Portal
- Click Payment methods
- Click Add new card β enter details
- (Optional) Set the new card as default
- (Optional) Remove the old card
When the new card is used
- Next billing cycle uses the new card
- Pending charges already in flight stay on the old card
- If a charge fails, Stripe retries on the new card
Multiple cards
You can keep more than one on file:
- Set one as default
- Other cards are backup β used automatically if default fails
Useful for travel-card-then-real-card situations.
Common issues
"My card is declined when adding it"
- Check expiry date
- Confirm sufficient credit / balance for a $0 verification charge (Stripe sends $0 to test the card; some banks block this)
- Some debit cards need "online purchases" enabled by your bank
"I don't see the Customer Portal link"
Every Stripe receipt for the subscription contains the same link in its footer. Find ANY past receipt for this subscription β the link works.
