Payments and invoices are handled by Paddle, our payment processor. You manage your payment method and access invoices from qaproof.io/app/settings/billing.
Accepted payment methods
Paddle supports the major payment methods for your region — typically credit and debit cards (Visa, Mastercard, American Express) and PayPal. The exact options shown at checkout depend on the country you're paying from.
Updating your payment method
- Open Billing.
- Click Manage subscription — opens Paddle's hosted portal in a new tab.
- From the portal, update the card or other payment method on file.
Changes apply to the next renewal — your current period stays paid.
Viewing and downloading invoices
The Billing page shows your transaction history with the most recent invoices first. Each row has:
- Date and amount.
- Plan name (Pro / Business / Scale) plus billing cycle (monthly / annual).
- Payment status (paid, pending, failed).
- Download invoice link — generates a branded PDF.
Adding company / tax info to invoices
Add your company name, billing address, and tax ID through Paddle's portal. They appear on every future invoice. Already-paid invoices keep the details that were on file at the time of payment — Paddle generally allows you to update past invoices via their support.
Failed payments
If a renewal payment fails, Paddle retries automatically over the next several days and notifies you by email each time. After the retries exhaust, your subscription is cancelled and the account drops to the Free plan. Update your payment method any time before that to resume service uninterrupted.
Refunds and disputes
For refund requests, email support@qaproof.io from the address on the account, mentioning the invoice number. We typically process refunds through Paddle within a few business days.
