When a payment fails, the contract also carries the code Shopify returned. This page is what those mean. *** ## Statuses | Status | When it's set | What it means | | - | - | - | | **Billing active** | The contract is collecting on schedule, which is how every contract starts. | The next charge fires on the date in **Next charge**. Nothing is needed from you. | | **Billing paused** | Someone paused billing, or a return was created and your [subscription settings](/documentation/methods/subscription/subscription-settings#billing-end) pause on return. | Nothing is collected. The next charge date is kept and shown struck through. The rental is unaffected: the customer keeps the item and it's still due back. See [Pause billing](/documentation/manage/subscriptions/subscription-actions#pause-billing). | | **Billing failed** | Shopify couldn't process a billing attempt. | The **Last payment** column carries the code Shopify returned, and [dunning](/documentation/manage/subscriptions/dunning) retries on the schedule you set. Look the code up in [Failure codes](#failure-codes) to see whether it needs you. | | **Billing canceled** | Someone canceled billing, or the cycle or membership it billed for was removed. | No further charges are raised. Where charges were still being collected and **End after collection** was ticked, the contract pauses first and ends once they settle. See [Cancel billing](/documentation/manage/subscriptions/subscription-actions#cancel-billing). | | **Billing complete** | The contract reached the end of its billing, rather than being canceled part way through. | No further charges are raised. Rows in this status are dimmed in the table, alongside canceled ones. | *** ## Failure codes The **Last payment** column shows the raw code. The charge page and the dunning banner show the message below. | Code | What it means | What to do | | - | - | - | | `EXPIRED_PAYMENT_METHOD` | The customer's card has expired | [Send a link to update the card](/documentation/manage/subscriptions/subscription-actions#send-a-link-to-update-the-card) | | `PAYMENT_METHOD_DECLINED` | The processor declined the card | Ask the customer to contact their bank or use another card | | `PAYMENT_METHOD_NOT_FOUND` | No active payment method on the contract | Make sure the customer has a vaulted card, then [change the payment method](/documentation/manage/subscriptions/subscription-actions#change-the-payment-method-on-a-contract) | | `INVALID_PAYMENT_METHOD` | The payment method isn't valid | Ask the customer to update their details or add a new method | | `BUYER_CANCELED_PAYMENT_METHOD` | The customer canceled the payment method | Ask the customer to update their payment details | | `INVALID_CUSTOMER_BILLING_AGREEMENT` | The billing agreement behind the payment is invalid | Ask the customer to add a new payment method | | `INVENTORY_ALLOCATIONS_NOT_FOUND` | Shopify found no inventory location for the line, which usually means the product was deleted | [Replace the deleted product](/documentation/manage/subscriptions/subscription-actions#replace-a-deleted-product) | | `AMOUNT_TOO_SMALL` | The charge is below what the gateway accepts | Raise the recurring price with [Edit billing](/documentation/manage/subscriptions/subscription-actions#edit-billing) | | `INVALID_SHIPPING_ADDRESS` | The shipping address is missing or wrong | Correct the address on the customer's profile | | `CUSTOMER_INVALID` | The customer account isn't valid | Check the customer in your Shopify admin | | `CUSTOMER_NOT_FOUND` | No matching customer account | Confirm the customer still exists in Shopify | | `INVOICE_ALREADY_PAID` | The invoice was already paid | Check the order status before charging again | | `PAYMENT_METHOD_INCOMPATIBLE_WITH_GATEWAY_CONFIG` | The payment method doesn't suit your gateway settings | Check your gateway configuration, or use another payment method | | `PAYMENT_PROVIDER_IS_NOT_ENABLED` | The payment provider is turned off | Turn it on in your Shopify payment settings | | `TEST_MODE` | The gateway is in test mode but a live card was used | Take the gateway out of test mode | | `AUTHENTICATION_ERROR` | Authentication failed during processing | Check the customer's payment details, then retry | | `TRANSIENT_ERROR` | A temporary problem at the gateway | Retry after a few minutes. Dunning does this for you | | `UNEXPECTED_ERROR` | Something else went wrong during billing | Retry. If it keeps failing, contact support from the app with the charge ID | *** ## Related documentation Retry failed payments on a schedule you set.
