Every "best BNPL apps" article lists the same five providers, copies their marketing claims about "50% AOV increases," and calls it a guide.

The problem? None of them show you what real Shopify stores actually use. They recycle provider-reported stats without checking whether merchants are actually installing these tools.

We took a different approach. We scanned 192,316 live Shopify stores and detected which buy now, pay later apps they're running. This isn't what BNPL companies claim merchants should use. It's what stores, from startups to brands doing millions per month, actually have installed.

The data tells a story that none of those articles mention: 96% of Shopify stores don't offer BNPL at all. And the ones that do look very different from those that don't.

How We Collected This Data

Dataset: 192,316 Shopify stores in the StoreInspect database

Method: Frontend detection patterns that identify BNPL provider scripts, checkout widgets, and JavaScript signatures on live stores.

What we detect: Third-party BNPL apps like Afterpay and Klarna that inject frontend scripts. We cannot detect Shop Pay Installments because it's built into Shopify Payments with no separate frontend signature. This means our BNPL numbers represent add-on BNPL providers only.

Traffic tiers:

Categories: 15 niches including Fashion (46,853), Home & Garden (26,612), Food & Beverage (18,047), Beauty (14,449), and more.

Limitation: Shop Pay Installments is likely the most-used BNPL option on Shopify since it's native to Shopify Payments. Our data covers the third-party BNPL market: the apps merchants actively choose to install alongside (or instead of) Shopify's built-in option.

---

Which BNPL Apps Do Shopify Stores Actually Use?

Out of 192,316 stores, 7,840 (4.1%) have a detectable third-party BNPL app installed. The market is a two-player race.

Afterpay dominates the third-party BNPL market on Shopify with nearly 3x the installs of Klarna. Sezzle, Affirm, and other providers had no detectable frontend installs in our dataset, which means they either have minimal Shopify adoption or operate through backend integrations we can't see.

97.8% of BNPL stores use a single provider. Only 171 stores (2.2%) run both Afterpay and Klarna together, which suggests most merchants pick one and stick with it.

Why only two players? Afterpay and Klarna both have native Shopify App Store integrations with frontend checkout widgets. Other BNPL providers like Affirm primarily integrate through Shopify Payments or backend APIs, making them invisible to frontend detection. Shop Pay Installments, Shopify's built-in BNPL, is the biggest player overall but doesn't appear as a separate app install.

---

BNPL Adoption by Traffic Tier

BNPL adoption correlates strongly with store size.

Stores with 200K+ monthly visitors are 6.7x more likely to offer BNPL than stores under 50K. The biggest jump happens between the under-50K tier (2.9%) and the 50K-200K tier (9.5%), a 3.3x increase. That's the "scaling" tier where stores start investing in checkout optimization.

Afterpay vs Klarna by Traffic Tier

Klarna gains ground as stores get bigger. At the under-50K tier, Afterpay outnumbers Klarna 4:1. By the 200K-1M tier, they're nearly even. At 1M+ traffic, Klarna overtakes Afterpay with over 60% of BNPL installs.

This makes sense. Klarna's pricing and feature set (virtual shopping, try-before-you-buy, broader international coverage) become more valuable at enterprise scale. Afterpay's simpler "pay in 4" model works well for smaller, predominantly US/AU-focused stores. For more on how store size influences app adoption, see our tech stack by growth stage analysis.

---

BNPL Adoption by Niche

Not every category benefits equally from BNPL. Higher average order values and considered purchases drive adoption.

Baby & Kids and Beauty lead BNPL adoption. Both sit above 7%, more than double the overall average. These are categories where customers make considered purchases (strollers, car seats, skincare routines) with higher average order values, exactly the scenario where splitting payments into installments makes the biggest difference.

Fashion is the largest BNPL market by raw numbers. With 2,679 BNPL stores, Fashion has more BNPL installs than any other category despite a lower adoption rate (5.7%). That's simply because Fashion is the biggest Shopify niche overall. Brands like Gymshark and Fashion Nova offer BNPL as standard at checkout.

Food & Beverage has the lowest adoption at 1.3%. Low average order values (a $30 coffee subscription doesn't need installments) and consumable products make BNPL less relevant here. If you're selling food, your checkout optimization budget is better spent on email marketing or subscription apps.

The BNPL Store Profile: What Sets Them Apart

BNPL stores aren't just adding a payment option. They're more invested across every dimension of their tech stack.

BNPL vs Non-BNPL Stores

Stores offering BNPL run more than twice as many apps, a third more tracking pixels, and are 3.5x more likely to be on Shopify Plus. Their average lead fit score of 84.6 puts them firmly in the "excellent" tier. These are stores that treat checkout as part of a broader conversion optimization strategy, not stores that install one payment widget and call it done.

Co-Installed Apps: What BNPL Stores Also Run

Rebuy shows the highest lift at 3.1x. Stores that offer BNPL are also much more likely to run upsell tools. This makes sense: BNPL reduces payment friction, and upsell tools capitalize on that reduced friction to increase order size. For a deep dive on upsell adoption, see our upsell apps study.

Klaviyo at 40.3% is the standout. More than 2 in 5 BNPL stores run Klaviyo, compared to fewer than 1 in 5 non-BNPL stores. BNPL stores invest more in email because they have the customer lifetime value to justify it. See our email marketing apps study for the full adoption breakdown.

The pattern is consistent across categories: stores that add BNPL also invest in reviews, support, and analytics. BNPL is a signal of a store that optimizes, not a one-off addition.

---

Shopify Plus and BNPL

Shopify Plus stores are dramatically more likely to offer BNPL.

Plus stores adopt BNPL at 5x the rate of standard stores. Within Plus, the split between providers is closer than the overall market:

Klarna's share grows among Plus stores (31% of Plus BNPL installs vs 22% on Standard), further supporting the pattern that Klarna skews toward larger, more established businesses.

For more on what separates Plus stores from the rest, see our Shopify Plus identification guide.

---

BNPL and Theme Investment

Stores that invest in their storefront also invest in BNPL.

Stores with paid themes (like Prestige or Impulse) are 1.8x more likely to offer BNPL than stores on free themes (like Dawn or Debut). This tracks with what we found in our theme analysis: theme choice is a reliable signal of how seriously a store invests in its customer experience.

---

Tracking and Ad Spend: BNPL Stores Run More Pixels

BNPL stores don't just have more apps. They run more advertising and tracking infrastructure.

TikTok Pixel and Pinterest Tag show the biggest relative gaps. BNPL stores are 2x more likely to run TikTok and nearly 2x more likely to run Pinterest tracking. These are stores diversifying their paid acquisition across multiple platforms, not just running Meta ads. For the full pixel breakdown, see our pixel detection study.

The Klaviyo pixel at 40.6% vs 19.4% mirrors the app adoption data. BNPL stores invest in email attribution because they have the revenue and customer base to make it worthwhile.

BNPL stores average 6.3 tracking pixels compared to 4.6 for non-BNPL stores. That's 37% more tracking infrastructure, which points to bigger marketing budgets and more sophisticated attribution. See our Meta ads study for more on how Shopify stores use paid advertising.

Afterpay vs Klarna: How to Choose

Based on our data and provider profiles, here's how the two main BNPL options compare.

Feature Comparison

When to Choose Afterpay

• Your customers are primarily in the US or Australia
• Your AOV is $50-$300 (the sweet spot for "pay in 4")
• You want the simplest integration with the widest brand recognition in the US
• You're in Fashion, Beauty, or Baby & Kids (where Afterpay dominates)

When to Choose Klarna

• You sell internationally (Klarna operates in 45+ countries vs Afterpay's focus on US/AU/UK)
• Your AOV is $200+ (Klarna's financing options handle higher ticket items better)
• You're on Shopify Plus or at the 200K+ traffic tier
• You want multiple payment options (pay in 4, pay in 30, financing up to 36 months)

When to Offer Both

Only 171 stores (2.2% of BNPL stores) run both. The argument for offering both: different customer segments prefer different BNPL providers, and offering choice can reduce checkout friction. The argument against: added complexity, potentially confusing checkout UX, and double the merchant fee negotiations.

Our data suggests that single-provider is the norm and it works. Pick the one that matches your customer base and focus your energy on other conversion levers.

What About Shop Pay Installments?

Shop Pay Installments is Shopify's built-in BNPL solution, powered by Affirm. It's available to US-based Shopify stores using Shopify Payments.

Why it doesn't appear in our data: Shop Pay Installments is part of Shopify Payments, not a third-party app install. It doesn't inject separate frontend scripts, so our scanner doesn't detect it as a distinct app.

What we know from Shopify's data:

• 60M+ Shop Pay users
• Up to 50% AOV increase (Shopify-reported)
• 28% fewer abandoned carts (Shopify-reported)
• No additional merchant fee beyond Shopify Payments rates

When Shop Pay Installments makes sense:

• You already use Shopify Payments (most stores do)
• Your customers are US-based
• You want BNPL without a separate app install or additional merchant fees
• You're looking for the lowest-friction option

When you need a third-party alternative:

• You sell internationally (Shop Pay Installments is US-only)
• You want longer financing terms (Klarna offers up to 36 months)
• You want the marketing and discovery benefits of Afterpay's or Klarna's consumer apps
• You need a BNPL solution that works without Shopify Payments

For many stores, the answer is both: Shop Pay Installments as the default, plus Afterpay or Klarna for customers who prefer those services.

The 96% Opportunity: Why Most Stores Don't Offer BNPL

95.9% of Shopify stores in our database have no third-party BNPL app. Even accounting for Shop Pay Installments users we can't detect, the gap is massive.

BNPL Adoption Gaps by Category

Electronics and Automotive stand out. High average order values, considered purchase behavior, and low current adoption (2.7% and 2.8%). If you sell $500+ products and don't offer installments, you're likely losing sales to stores that do.

Jewelry at 95.1% without BNPL is surprising given the price points. A $2,000 engagement ring is the perfect BNPL use case. This gap represents a real competitive advantage for jewelers who do offer installment options. For the full picture of what jewelry stores invest in (and where they fall short), see our jewelry store app study.

For agencies: Use StoreInspect to filter stores by category and missing payment apps. A jewelry store doing 100K monthly visitors without BNPL is a straightforward pitch: "Your competitors offer installments. Here's how much AOV you're leaving on the table." For more prospecting angles, see our guide to selling to Shopify stores.

Does BNPL Actually Increase Sales?

We can't measure conversion rates directly from frontend data. But we can compare the profile of BNPL vs non-BNPL stores.

BNPL stores score 20 points higher on our lead fit scale and are 3.5x more likely to be on Shopify Plus. They invest more in every aspect of their stack: marketing, support, analytics, and conversion optimization.

This doesn't mean BNPL causes higher revenue. Stores that can afford $2,300+/month for Shopify Plus can also afford 4-6% BNPL merchant fees. But the correlation is strong: BNPL adoption is a reliable signal of a well-optimized, revenue-generating store.

Industry data supports the impact:

• Klarna reports 30% conversion increases and 45% AOV lifts for merchants
• Afterpay claims a 20% conversion boost and up to 40% AOV increase
• Shopify reports Shop Pay Installments reduce cart abandonment by 28%
• General BNPL research estimates 20-30% conversion increases and 30-50% AOV increases

Even taking these provider-reported numbers with healthy skepticism, the directional evidence is clear. Reducing payment friction at checkout increases conversions, especially for purchases above $100.

FAQ

What is the best buy now pay later app for Shopify?

Based on our data from 192,316 stores, Afterpay is the most popular third-party BNPL app with 73.6% of BNPL installs. Klarna holds 24.2%. However, Shop Pay Installments (built into Shopify Payments) is likely the most-used overall since it requires no separate app. Choose Afterpay for US-focused stores with moderate AOV. Choose Klarna for international stores or high-ticket items.

How much do BNPL apps charge Shopify merchants?

Afterpay charges 4-6% plus $0.30 per transaction. Klarna charges 2.49-5.99% plus $0.30 per transaction. Shop Pay Installments is included with Shopify Payments at no additional merchant fee. These rates are higher than standard credit card processing (2.5-2.9%), but providers argue the conversion and AOV increases more than offset the cost.

Does buy now pay later increase Shopify sales?

Provider-reported data suggests 20-30% conversion increases and 30-50% AOV increases. Our data shows BNPL stores have higher lead fit scores (84.6 vs 64.8), more apps (3.9 vs 1.7), and are 3.5x more likely to be on Shopify Plus. Correlation is strong, though we can't isolate BNPL as the sole cause. The stores that adopt BNPL tend to optimize across every aspect of their checkout.

Can I use multiple BNPL apps on Shopify?

Yes. Our data shows 171 stores (2.2% of BNPL stores) run both Afterpay and Klarna. However, 97.8% stick with a single provider. Adding multiple BNPL options can increase checkout complexity without proportional benefits. Pick the one that best matches your customer demographics and average order value.

What percentage of Shopify stores offer BNPL?

4.1% of the 192,316 stores in our database have a third-party BNPL app installed. This rises to 9.5% at the 50K-200K traffic tier and 21.6% at 1M+ traffic. The true figure including Shop Pay Installments users is likely higher, but third-party BNPL adoption remains low overall.

Which niches benefit most from BNPL?

Baby & Kids (7.4% adoption) and Beauty (7.3%) lead. Fashion has the most BNPL stores by volume (2,679). Food & Beverage has the lowest adoption at 1.3%. Categories with higher average order values and considered purchases see the highest BNPL adoption.

Is Afterpay or Klarna better for Shopify?

It depends on your market. Afterpay dominates for US/AU-focused stores under 200K monthly visitors. Klarna overtakes Afterpay at the 1M+ traffic tier, where it holds 62.5% of BNPL installs. Klarna also offers more payment flexibility (pay in 30, financing) and broader international coverage (45+ countries vs Afterpay's US/AU/UK focus).

Do I need Shopify Plus for BNPL?

No. Both Afterpay and Klarna work on all Shopify plans. However, Plus stores adopt BNPL at 5x the rate of standard stores (12.8% vs 2.6%). Plus merchants benefit from checkout extensibility, which allows deeper BNPL integrations.

Should small Shopify stores offer BNPL?

If your average order value is above $75-$100, BNPL can reduce purchase hesitation. Our data shows even at the under-50K traffic tier, 2.9% of stores offer BNPL. The question is whether the 4-6% merchant fee is justified by your conversion rate. Start with Shop Pay Installments (no additional fee) and add a third-party provider if your data shows demand.

What apps do BNPL stores commonly run alongside?

Klaviyo is the top companion at 40.3% of BNPL stores (2.1x the rate of non-BNPL stores). Rebuy shows the highest lift at 3.1x, suggesting BNPL and upsell tools work together to reduce friction and increase order size. Loox Reviews (2.7x lift) and Tidio Chat (1.8x lift) also over-index on BNPL stores.

How does BNPL affect cart abandonment?

Shopify reports that Shop Pay Installments reduces cart abandonment by 28%. Third-party data suggests similar ranges. Our data can't measure abandonment directly, but BNPL stores run 37% more tracking pixels on average, indicating they track and optimize the full purchase funnel more aggressively.

Is BNPL safe for merchants?

BNPL providers absorb the credit risk. Merchants receive full payment upfront (minus fees), and the BNPL company collects installments from the customer. The merchant's risk is primarily the higher transaction fee. CFPB data shows BNPL charge-off rates of 1.8-2.6%, which is the provider's problem, not the merchant's.

---

Summary

Key findings from 192,316 Shopify stores:

The bottom line: BNPL is underadopted on Shopify. Only 4.1% of stores offer a third-party installment option, and the adoption gap is biggest in high-AOV categories like Electronics, Jewelry, and Automotive where installments matter most. Stores that do offer BNPL are measurably more invested in their entire tech stack, not just payments. If your average order value justifies the 4-6% fee, BNPL is a straightforward checkout optimization with proven conversion impact.
