What is a Fixed Installment payment?

A Fixed Installment payment lets customers spread the cost of a purchase over a set number of months – 3, 6, 12, 24– paying the same amount each month. There are no recalculations and no surprises: the monthly amount is shown clearly at checkout before the customer confirms. Riverty manages the consumer credit side entirely, paying out the merchant and handling everything that follows.

How do Fixed Installment payments work?

During checkout, Riverty automatically determines the customer's eligibility a based on factors such as the order value, consumer profile, and merchant agreement. The customer then reviews the monthly payment amount upfront, and confirms their purchase. In Germany and Austria, monthly payments are collected automatically via direct debit. In the Nordics, customers receive a payable term each month. The merchant receives payment from Riverty and isn't involved in the ongoing collection process.

How can merchants offer installment payments?

Fixed Installment payments are available via the Riverty Payment API direct integrations or via our Partners. Once integrated, eligibility and available plan lengths are determined dynamically at checkout – no manual intervention needed per transaction. Merchants have full visibility on acceptance rates, performance, and settlement through the Riverty Merchant Portal. For merchants considering ecommerce installment payments across multiple markets, Riverty’s suite covers local consumer behaviour in each.

Are Fixed Installment payments part of BNPL?

Like all Riverty BNPL products, it contributes to measurable commercial uplift – +15% more purchases, +20% returning customers, and +16% order volume on average.

What are the benefits of fixed installment payments for merchants?

Fixed installment payments directly address the price barrier on higher-value items by making the monthly cost, not the total, the headline number. Merchants typically see average order value increase by up to 20%, with even greater uplift when payment messaging appears on the product page rather than only at checkout. Beyond revenue, Fixed installments expands the addressable customer base, reduces returns through more considered purchasing, and adds a flexible promotional lever: merchants can choose to offer zero-interest plans to drive sales without changing the product itself.

How are refunds handled in installment payments?

A full refund returns the first installment to the consumer. A partial refund is deducted from the final installment. Riverty manages the refund process – the consumer experience stays clean and the merchant isn’t required to intervene. All refund activity is visible through the Riverty Merchant Portal.

In the Nordics, consumers receive a payable term each month via the MyRiverty app. For merchants operating across multiple markets, Riverty’s full payment suite covers local preferences, including Pay in 3, direct debit, and 14- and 30-day invoice.
