Payment methods and currency

Which payment methods subscriptions can use, how you and your customers update them, and how each subscription keeps its own currency.

Last updated: 2026-10-18

Chargezen charges each subscription through its Shopify subscription contract, using the payment method saved in Shopify: cards, PayPal or Shop Pay. The subscription's sidebar shows the method, such as the card brand and last four digits, PayPal or Shop Pay.

Change the payment method on a subscription

1

Open the subscription

Go to Subscriptions → Manage → Contracts and choose it.

2

Choose another saved method

Under Payment method, choose Choose payment method. Pick from Saved payment method and choose Save payment method. This changes the method for this subscription only.

1

Send the link

Under Payment method, choose Send payment update link. The dialog shows the recipient. Choose Send email.

2

Customer updates

Shopify emails the customer a secure link to update their payment details. The next charge or retry uses the new method.

You'll also find Send payment update link on failed charges in Orders → In dunning, and Update payment method on a failed attempt in the subscription's Payments section.

How customers update it themselves

Automatic reminders

These default workflows email or text customers about their payment method. Edit them under Workflow automations:

  • Update payment method email and text: sent up to 7 days before a renewal when the method can't be charged.
  • Card expiring email and text.
  • Card expired email and text.

Currency

  • Each subscription has its own currency, and prices on its detail page are shown in it.
  • When you create or import a contract, the Currency field (or the CSV Currency column) sets it. It starts as your shop currency.
  • A shipping rate is only used when its currency matches the subscription's.
  • Order pages show the amounts in the currency the customer paid in. Analytics report in your shop currency.
Coming from Stripe?

Choose Stripe as the payment method when you create or import a contract, and Chargezen brings the customer's default Stripe payment method into Shopify. See Move Stripe payment methods.

Troubleshooting

Shopify can't send an update link for a method that's revoked or inactive. Choose another of the customer's saved methods, or ask them to pick one from their Shopify customer account.

Choose payment method is missing

It's only shown on active subscriptions. Resume or reactivate the subscription first.

A subscription charges in the wrong currency

The currency is set when the contract is created. Check the Currency value used at import.
