Buy now, pay later (BNPL) is a type of short-term financing that lets your customers pay for purchases over time, often with zero or low-interest rates. BNPL payments first gained traction with online shoppers looking to finance apparel and beauty purchases.
While BNPL surged in popularity during the pandemic to finance large purchases, today, people have begun to use these installment plans more frequently for everyday purchases.
This article takes a deep dive into what BNPL is, how it works, the pros and cons of offering this financing option, and the solutions you can use to implement it in your business.
How Does BNPL Work?
While the exact terms of purchase will vary based on the financing solution, in general, the BNPL process begins with a customer choosing their items and selecting the BNPL option at checkout. The customer must then be approved and decide on a payment plan. Once the transaction is complete, your business will receive the full payment amount, while the customer will pay later according to the BNPL terms.
However, transaction fees for BNPL payments are typically about double the cost of standard credit card processing fees—approximately 6% instead of around 3%.
Buy Now, Pay Later in 5 Steps
Step 1: Customer Shops
Customers shop normally and select the products they want to buy from your store.

Step 2: Customer Selects BNPL at Checkout
When customers go to checkout, they select the BNPL option as their payment method.

Step 3: Customer Applies for Approval
Before becoming eligible for BNPL financing, customers will sometimes undergo a quick credit check, which typically takes less than a minute. This is not only used for loan approval, but your credit score will also determine your APR rates.

Step 4: Customer Chooses a Payment Plan
Once approved, customers can view their financing options and generally choose between paying monthly or in four biweekly installments. Note, however, that not all BNPL financers offer term options. For some, there is only one timeline, interest rate, and monthly fee to choose from.

Step 5: You Get Paid, Customer Pays Later
When your customer completes their purchase, you will receive the full amount upfront. All that you owe to the BNPL company is the processing fees. Your customer will then start paying the BNPL company according to their financing terms to avoid any interest or late fees. They can also choose to pay off their entire purchase at any time.

Sometimes, depending on the plan and BNPL company, the customer will owe a portion of the purchase upfront as a down payment. Depending on their selected terms, this down payment can be 0%–70% but typically runs anywhere from 0%–25%.
Pros & Cons of Offering BNPL
There are lots of great benefits that can come from offering BNPL to your customers. As you’ll see below, most BNPL providers claim to significantly increase conversion rates and average order value. This is the main draw for businesses.
For customers, BNPL can be a convenient way to finance a purchase without using a credit card.

BNPL Frequently Asked Questions (FAQs)
How does BNPL compare to a credit card?
While BNPL services and credit cards operate mostly the same—letting you buy items and pay for them later—BNPL providers typically have higher merchant fees than credit card payments. However, BNPL providers also usually offer lower interest rates, late fees, and penalties. Additionally, there are BNPL options that do not require good credit.
How can I offer BNPL at checkout?
You can sign up for most BNPL providers for free. Simply choose a provider that integrates with your website, sign up, and use the plug-in to add the provider to your checkout and product pages. You then pay the BNPL company in transaction fees for every purchase processed through the financing company.
How much does BNPL cost for merchants?
BNPL is typically free for merchants to sign up for and use. You only pay for BNPL as you use it in the form of processing fees, typically ranging from 1.5% to 6%.
How do BNPL companies make money?
BNPL companies make the majority of their money through processing fees. They also make money from late fees and other consumer penalties.
What happens if you miss a payment?
Typically, you are given a grace period of 5 to 14 days to make your payments. From there, the late penalties vary from a set fee, to a fine equal to 25% of your purchase, to a hit on your credit score—it depends on which company you are working with.
How much can you finance with BNPL?
Most BNPL companies have a spending limit ranging from $5,000 to $18,000. Some, however, do not have set caps and base their limits on your credit score.
