What is BNPL?

Buy Now, Pay Later (commonly referred to as BNPL) is a form of credit that one could use to make purchases and then pay in regular installments over a pre-agreed timeframe with little or no interest. Unlike with credit cards, BNPL typically does not build revolving debt — which many consumers may find a more straightforward option. Consumers can split their purchases into two, four or more payments depending on the provider and merchant setup.

Unlike traditional credit, BNPL aims to get you approved quickly and does not require a credit check for most smaller purchases. The best part is, it takes away the obstacle of paying entirely in advance that can open it up to lots more merchants — and increase conversion rates, as well.

The most well known BNPL providers themselves are Klarna, Afterpay, Affirm and PayPal BNPL; each has its own set of terms, integrations and consumer protections. These are essentially the components you use within your payment ecosystem and tie into a merchant’s account, payment gateway, and payment processor. This way, transactions can be authorized, settled and reconciled effectively without any compromise to the security of cardholder data.

Moreover, with the addition of Buy Now Pay Later solutions to the checking out experience, businesses can offer a purchasing method that meets consumers’ changing demands for flexibility and modernity – ultimately leading to increased conversion rates and repeat custom.

BNPL Integration Options

  • Hosted BNPL Checkout Pages: This option visits the BNPL provider’s page for approval and payment. It helps minimize merchants’ integration effort while minimizing their PCI compliance scope as sensitive payment data is transmitted to the provider.
  • API-Driven Integration: A streamlined experience, API-driven integration integrates BNPL directly into the merchant’s checkout process. The customer does not leave the site and in the background, the BNPL process is approved. This process guarantees minimal impact, brand consistency, and overall improvement in the user interaction.
  • POS Integration: Merchants have an option of integrating BNPL into their physical point-of-sale mechanisms for customers to use in-store. This lets shoppers leverage installment options when buying in a store, and creates a seamless payment experience across online and offline.
  • Mobile App Integration: BNPL integration in the apps of such ‘mobile first’ retailers is highly beneficial. Shoppers can choose BNPL at checkout, see installment plans and agree to receive notifications on upcoming payments without leaving the app.
  • Hybrid: Some online and most in-store and mobile payment options work effectively for merchants by providing a consistent BNPL experience across the channels. This approach caters to omnichannel consumers and optimizes conversion opportunity.

Compliance, Security, and Risk Management

The schedule of payments and full cost have to be presented by the merchants openly so that they don’t run into regulatory trouble.
  • Fraud Prevention: Fraud mitigation is critical for BNPL, particularly because of card-not-present transactions. Providers leverage risk scoring, identity verification and machine learning to identify fraudulent on-writing. Traders should adopt these tools and watch for any suspicious behaviour.

  • Transparent Communication: Make BNPL terms transparent to customers, both at checkout and in confirmation emails. Openness increases trust and helps avoid conflicts or delays in payments.

  • Large Cost Display: Clearly show the total amount of purchase cost and take installments. Transparency contributes to user trust in the service and alleviates checkout hesitation.
  • Reduce additional clicks: Don’t redirect customers to unnecessary pages or approval steps. Streamlined workflows enhance conversion rates.
  • Seamless Approval Status: BNPL should approve in the background without impacting checkout. API compatibility enables instant verification and an uninterrupted shopping experience.
  • Support & FAQs: Links to details about terms of payment, late fees and how BNPL works should be readily available. The more customers know about the terms, the likelier they are to use BNPL.
