If you run a Magento store, you’ve probably seen this pattern in your analytics: decent traffic, decent add-to-carts, and then a big drop the moment someone hits the payment page. Happens to almost everyone. Sometimes it’s a shipping cost surprise, sometimes it’s just the total looking bigger than expected once it’s all added up.

One thing that’s helped a lot of stores with this  Buy Now, Pay Later. You’ve probably seen it on other sites already, that little “or 4 payments of £X” line under the price. It doesn’t sound like much, but it changes how people decide to buy.

We build these integrations for Magento stores at Team Magento pretty regularly now, so this post is basically a rundown of what BNPL actually does, how it gets built into a Magento checkout, and a few things that tend to go wrong if it’s rushed.

So what is BNPL, exactly?

Short version: customer gets the product now, pays for it in parts later. Usually 3 to 6 installments, usually no interest if they pay on time. Klarna, Afterpay, Affirm, PayPal Pay Later  these are the names most people recognize.

It’s not a new idea (layaway existed decades before any of these apps), but the online version took off because it removes that one moment of hesitation right before checkout. A £200 order feels a lot less scary as three payments of about £67.

For a Magento store, offering this usually means:

• People add slightly more expensive items to the cart, since the full price isn’t due immediately
• Fewer people abandon at the last step
• Some repeat purchases, because the checkout experience felt easy the first time

None of this is guaranteed  it depends heavily on what you’re selling.

Does it actually move the numbers?

Depends who you ask, honestly, and it varies a lot by store. But directionally, most of the published data (and what we’ve seen across client stores) points the same way. Here’s a rough comparison  treat these as ballpark industry figures, not something to quote in a pitch deck:

Your mileage will vary. A store selling £15 phone cases probably won’t see much lift from BNPL. A store selling £300 furniture pieces might see quite a lot.

Getting BNPL onto a Magento checkout

There’s a bit of a myth that this is a one-click plugin install and you’re done. Sometimes it is that simple. More often, there’s a handful of steps in between.

• Pick a provider first:  Klarna and Afterpay dominate the UK/Australia space, Affirm leans more U.S. Fees, eligibility checks, and settlement timelines differ between them, so it’s worthactually reading the merchant terms rather than just going with whichever one you’ve heard of.
• Then the module:  Off-the-shelf Magento 2 extensions cover most standard cases fine. Where it gets custom is stuff like  only showing BNPL above a £50 order, or hiding it for certain product categories that don’t qualify under the provider’s rules. That’s when you’re looking at a proper module build instead of a plugin.
• Checkout UI matters more than people think:  We’ve seen stores add a BNPL button and just… leave it there with no explanation of terms. Customers get suspicious of anything that looks like hidden fees, so the installment breakdown needs to be visible before they click “place order,” not after.
• Test the edge cases:  What happens on a partial refund? A cancelled order after the first installment’s gone through? These aren’t rare scenarios  they come up constantly once you’re live, so better to catch them before launch than after a customer complaint.

If none of that sounds like a weekend project for your dev team  it usually isn’t  bringing in someone who’s done a few of these before saves a fair amount of back-and-forth.

Where this tends to go wrong

A few recurring issues we run into:

Site speed takes a hit sometimes. Some BNPL widgets load external scripts that aren’t exactly lightweight, and if nobody checks page speed after adding it, checkout can noticeably slow down. Worth a before/after test.

Trust is still a real barrier for some shoppers. BNPL has grown fast, but not everyone’s used it, and some people assume there’s a catch. Being upfront about terms  literally spelling out “3 payments, no interest, here’s the schedule”  helps more than most stores expect.

Older Magento setups can be finicky. If your store’s on an older version or has heavy custom theming, some provider SDKs don’t play nice out of the box. A compatibility check before committing to a provider avoids a lot of wasted dev hours.

A few questions people usually ask

Q1. Is BNPL worth it for cheap products?
Not really the main use case. It shines more on mid-to-higher ticket items where paying it all at once is the actual objection.

Q2. Will it slow my site down?
Possibly, if it’s not implemented cleanly. Test load times after adding it  don’t assume.

Q3. Which provider is best?
No universal answer  depends on your customers’ region and habits. A lot of stores just offer two options and let shoppers pick whichever they already have an account with.

Q4. Custom module or ready-made plugin?
Plugin’s fine for most standard stores. Custom modules make sense once you need specific business rules around when BNPL shows up.

Where this is all heading

BNPL isn’t really “emerging” anymore; it’s closer to becoming an expected checkout option, the way Apple Pay or PayPal became expected a few years back. Stores that skip it aren’t necessarily losing sales outright, but they’re probably losing the price-sensitive segment to whoever down the street does offer it.

If you’re on the fence about whether it’s worth building, for most mid-sized Magento stores, the cart-abandonment savings alone tend to justify it.

If you want a hand figuring out which provider fits your store and getting it built properly into your checkout, that’s something we do at Team Magento  happy to talk through what makes sense for your setup.
