Paid plans are billed per custom domain\. You manage your subscription, view invoices, update payment methods, change plans, cancel, and request refunds from the Billing section of the OptinStack dashboard\. Paddle is our merchant of record, so payments are processed by Paddle and tax \(including VAT\) is calculated and collected by Paddle as the merchant of record\.

## Where to manage billing

Open Settings → Billing in the dashboard\. The Subscription card shows the workspace plan, the active hostname plan, the billing cycle, the current period, and the next payment date\. From there you can change plan, cancel at period end, request a refund, and open the payment\-methods portal\.

> **Info:** Invoices are listed natively in the dashboard under Settings → Billing → Invoices. Each row shows the amount, status, date, plan, and billing period, with the payment reference available in the detail view.

## Payment methods

We accept major credit cards including Visa, Mastercard, Maestro, JCB, Discover, and Dankort, plus PayPal\. To update a card or PayPal account after checkout, use the Payment & invoices action in the Subscription card to open the Paddle customer portal\. OptinStack does not store card details itself\.

## Invoices and receipts

Every charge appears in the Invoices card with its amount, currency, status, paid date, plan, and billing period\. The payment reference is shown in the invoice detail view; include it when contacting support about a charge\. Paddle also emails a receipt to the address used at checkout\.

### Where do I find my invoices?

Open Settings → Billing → Invoices in the OptinStack dashboard. Each invoice row opens a detail view with the amount, status, date, plan, billing period, and payment reference. You do not need to leave the dashboard to view invoices.
