Buy now, pay later: how can it work for my business?

Learn about the potential benefits of buy now, pay later (BNPL), if it's right for your business, and discover some of the BNPL solutions out there.

The ‘buy now, pay later’ (BNPL) phenomenon has taken the world by storm. Although the concept has existed for well over a decade, BNPL boomed during COVID due to the rise in financial instability and online shopping.

Promising businesses increased conversion rates, average order values, and repeat purchases, implementing BNPL seems like a no-brainer.

However, buy now, pay later solutions seem to work better for some businesses than others. In this article, find out whether BNPL is right for your business and which BNPL vendor to choose.

But first, what exactly is buy now, pay later?

Buy now, pay later, or BNPL for short, is a form of financing that lets customers pay for something over time. It generally can be categorized into two types: invoicing and installments.


The customer checks out without paying anything and needs to repay the full amount in 14-30 days. This is a zero interest option and most popular in Europe.


The customer repays the balance in bi-weekly or monthly payments. For some BNPL solutions, a deposit is collected at time of purchase. This is most popular in North America.

How does BNPL work?

Very simply, the customer makes a payment via a buy now, pay later payment method. The BNPL provider pays the merchant the full purchase amount. The customer then repays the BNPL provider either the full amount or in installments.

On a more detailed level, a repayment works differently depending on if it’s classed as a credit loan or a deferred payable. With a credit loan, BNPL is accounted for as a customer loan. With a deferred payment the merchant buys an “I owe you” (IOU) from the BNPL provider. This dfference can affect the repayment terms for the customer and the contracting terms for the merchant.

How repayment works for buy now, pay later

BNPL providers have different terms and conditions on certain topics, including:

  • Repayment periods. Customers either need to make the repayment in full at the end of the month (like credit cards), or pay in installments on a weekly, biweekly, or monthly basis.
  • Late fees. There are a range of associated fees when a customer doesn’t pay on time. For instance, interest or late fees, monthly fees, or account reopening fees.
  • Payment channels and types. They also cater to different channels and payment types, like in-person, online, and recurring payments.
  • Marketing requirements. Some expect advertisements on the merchant’s website, like promo banners, and marketing budget allocation.
