Multi-currency customers

Before you invoice a customer, create an invoice item by passing in the customer id, amount, and currency. Only add invoice items to a single customer at a time to avoid adding them to the wrong one.

The maximum number of invoice items is 250. Creating an invoice adds up to 250 pending invoice items with the remainder to be added on the next invoice. To see your customer’s pending invoice items, see the Customer details page or set the pending attribute to true when you use the API to list all of the invoice items.

curl https://api.stripe.com/v1/invoiceitems \
  -u "

:" \
  -d customer=
{{CUSTOMER_ID}} \
  -d amount=1000 \
  -d currency=cad

You must pass in the currency parameter when you issue a multi-currency invoice. The currency parameter dictates which invoice items get pulled into the invoice. For example, if you were to create two invoice items—one in USD and the other in CAD—for the same customer, setting the currency to CAD would only pull in the CAD invoice item (ignoring the USD invoice item).

curl https://api.stripe.com/v1/invoices \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d customer=
{{CUSTOMER_ID}} \
  -d collection_method=send_invoice \
  -d days_until_due=30 \
  -d pending_invoice_items_behavior=include \
  -d currency=cad

If there’s an issue with the invoice, you can create a credit note. If you need to apply the credit to the customer’s credit balance (as opposed to back to the original payment method), Stripe allocates the credit amount to the CAD-specific credit balance.

curl https://api.stripe.com/v1/credit_notes \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d invoice={{INVOICE_ID}} \
  -d reason=duplicate \
  -d amount=1000 \
  -d credit_amount=1000

To see how much credit a customer has in each currency, use the invoice_credit_balance parameter:

curl -G https://api.stripe.com/v1/customers/{{CUSTOMER_ID}} \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d "expand[]"=invoice_credit_balance

The customer’s credit balance is drawn down from the next CAD invoice created for this customer. It won’t, however, be drawn down for invoices created in different currencies.
