For users registered in Postgrain until 12/12/2018 are using the prepaid model, you buy credit in days to be able to use the services available on the platform. Credit can be purchased through Paypal using a credit card. And credit card payments are cleared immediately.
The renewal of the service is not carried out automatically, being necessary to renew manually, always at the end of the contracted period.
If you need the invoice just contact us.
If your registration was made after 12/12/2018, the payment method available is by Visa or Master credit card. You can read more about this article: How does recurring subscription work?
