We use shareit for payment processing
Info from shareit FAQ
Invoices for orders will be created only after payment has been received. If you pay by credit card or have the amount charged to your account (electronic debit or online bank transfer), we will immediately issue an invoice for your order. For orders paid for by bank transfer, check or cash, you will first receive an order confirmation, and your invoice will be sent to you after payment has been received. In any case, we will automatically e-mail your invoice or order confirmation to your billing address. The order documents will be included as a PDF attachment to the e-mail .
You can also view and print your order documents any time after completing your order. To do so, simply log in to the secure "My Account" area. Here, you will find your order overview and any related documents.
