Typeform is a prepaid online service, so all services are paid for upfront and before use by credit or debit card, PayPal (in Europe), or digital wallets like Apple or Google Pay. We can’t support purchase orders, or send you an invoice that requests payment. However, manual invoices are available for users on Enterprise plans. You can contact our Sales team for more information here. After any order or payment, an invoice/receipt detailing the transaction, and showing it’s been paid, is sent to the billing email address for your account.
