About Ratepay

General information about Ratepay

Ratepay is a whitelabel online service provider which allows merchants to provide their customers secure and commonly used payment methods. Below are the payment methods that are supported by Ratepay:

• Open Invoice - Open Invoice is a payment method that enables customers to purchase goods or services on credit and pay at a later date. With Open Invoice customers receive an invoice detailing the amount owed, payment terms, and due date.

  When a customer selects Open Invoice during the checkout, Ratepay performs a real-time risk check. The advantage of using Open Invoice is that it can improve cash flow for both the buyer and merchants:

  • For buyers: They can purchase goods or services without having to pay for them immediately, which can be beneficial for managing their finances.
  • For merchants: With Ratepay you profit as a merchant from a full invoice purchase service. You pass on all the invoice data during the order to Ratepay, who takes over the complete billing and debtor management. As merchant you get a payment guarantee.
• SEPA Direct Debit - Ratepay offers classical hire purchase and SEPA direct debit. SEPA Direct Debit is a payment method that allows merchants to collect payments from buyers directly from their bank account via their IBAN, who have granted them permission to do so.
