Update the payment method attached to the account or service before the next automatic collection attempt.
Applies to: Billing, payments and invoices
WHMCS records invoices, payments, credits and tax information against the customer account. A catalogue price change does not rewrite an existing invoice, and a service status does not always change at the same moment as an invoice status.
Before you start
- Use a trusted browser and confirm the portal uses HTTPS.
- Have the service and next due date available.
Step-by-step
- Sign in to the Customer Portal and open the payment-method or billing area available for the account.
- Add or authorise the new payment method through the secure payment provider. Tudor Internet does not need the full card number in a support ticket.
- Set the new method as the default where the portal offers that control, or select it on the relevant service or invoice.
- Check whether an already-issued invoice must be paid manually; changing the default method may not automatically retry an existing failed invoice.
- Remove an obsolete stored method only after confirming no active service or pending invoice still depends on it.
- Review the next due date and keep sufficient funds available for the scheduled collection.
Confirm the result
- The new payment method is shown as available or default without exposing full card details.
- Any current unpaid invoice has a clear payment plan.
Common problems
| Symptom | Likely cause | What to do |
|---|---|---|
| The new card cannot be added. | The bank rejected verification, browser security blocked the provider, or the billing address does not match. | Retry once with accurate billing details, then contact the bank or use another supported method rather than submitting repeated attempts. |
| An old card was charged after the update. | The invoice attempt was already initiated or the service retained a different payment method. | Check the transaction time and service payment-method setting, then open a billing ticket with the invoice number. |
When to contact Tudor Internet
Open a ticket through the Customer Portal when the checks above do not resolve the issue, when an action is unavailable for your service, or when continuing could risk data loss or service interruption. Include the following so the request can be investigated efficiently:
- The customer account email address
- The affected invoice, service, domain or ticket number
- The exact message and the time it appeared
Do not send passwords, private keys, full payment-card details, one-time authentication codes or unredacted identity documents in an ordinary support reply.
