Imagine shopping online and splitting your payment into smaller installments — without credit cards, hidden fees, or long approval steps. That’s exactly what Klarna made possible.
Founded in 2005 in Stockholm, Sweden, Klarna began as a simple online checkout solution but quickly evolved into a global Buy Now, Pay Later (BNPL) leader. Today, it powers smoother payments for over 150 million users across Europe, the U.S., and Asia, redefining how people shop, pay, and manage finances.
In 2025, Klarna offers much more than installment payments. It’s now a complete shopping and financial experience with rewards, budgeting tools, virtual cards, and AI-based price comparisons — all accessible from a single app.
By the end of this guide, you’ll know what Klarna is, how it works, how it earns, and how you can create your own Klarna-like BNPL platform with Miracuves in 3–6 days.
What is Klarna? The Simple Explanation
Klarna is a Sweden-based buy now, pay later (BNPL) and shopping app that lets users split purchases into interest-free installments, pay later within 30 days, or pay upfront. It partners with thousands of global retailers and gives users flexible payment options directly at checkout or through the Klarna app.
The core problem Klarna solves is shopping affordability and convenience. Instead of paying the full amount at once, users can spread payments over time without credit cards, hidden fees, or complicated approvals.
Its target users include online shoppers, young adults, and budget-conscious consumers who want simple, flexible payment options with transparent timelines.
As of 2025, Klarna serves 150+ million users and partners with 500,000+ merchants across Europe, North America, and Asia. It has become a leading global BNPL service, known for its fast checkout experience, instant decisions, and built-in shopping tools.
Klarna became successful because it offers a smooth user experience, strong merchant partnerships, and a modern alternative to credit cards — all backed by secure banking-grade technology.
How Does Klarna Work? Step-by-Step Breakdown
Klarna operates as a Buy Now, Pay Later (BNPL) and shopping platform that lets users split purchases into installments, pay later, or pay instantly — all while offering a smooth, interest-free experience for most transactions. It integrates with thousands of online and offline merchants globally and provides a shopper-friendly mobile app that centralizes payments, delivery tracking, and rewards.
For Users
1. Account Creation
Users sign up using their phone number or email, verify identity, and connect a debit/credit card or bank account. Klarna then provides spending limits based on internal risk assessments.
2. Shopping & Checkout
Users can shop directly through the Klarna app or at partner stores like H&M, Sephora, Nike, ASOS, and thousands more. At checkout, they choose from Klarna’s payment options:
- Pay in 4 (split into four interest-free payments)
- Pay in 30 Days
- Pay Now
- Financing (long-term monthly installments with interest)
3. Payments & Schedules
Klarna automatically deducts installments on the due date, sending reminders through the app. Payment schedules and upcoming dues are displayed clearly so users can track everything easily.
4. Order & Delivery Tracking
Klarna integrates with merchants and shipping partners to show real-time delivery updates inside the app. Users can track purchases, request returns, or manage refunds without visiting the store website.
5. Rewards & Cashback
Klarna’s rewards program gives points for every purchase, redeemable for gift cards or cashback. The app also features price-drop alerts, curated deals, and exclusive shopping discounts.
For Merchants
1. Integration
Businesses integrate Klarna using APIs, plugins (Shopify, WooCommerce, Magento), or POS systems for offline stores.
2. Instant Payouts
Klarna pays merchants upfront for the full purchase amount (minus a small merchant fee), while users pay Klarna back in installments. This reduces merchant risk and boosts conversions.
3. Increased Sales & Reduced Cart Abandonment
BNPL options increase order value, encourage impulse purchases, and reduce checkout drop-offs.
4. Marketing & Exposure
Merchants get featured inside the Klarna app’s shopping feed, reaching millions of shoppers actively browsing deals.
Technical Overview (Simple)
Klarna uses a secure fintech infrastructure that connects payments, risk scoring, and merchant systems seamlessly:
- Cloud-based architecture for global scalability
- Real-time risk assessment & credit scoring models
- PCI DSS–compliant payment gateways
- Encrypted card tokenization for secure transactions

Klarna’s Business Model Explained
Klarna operates on a buy now, pay later (BNPL) and payment processing model, serving both consumers and merchants. Its business is built on driving higher conversion rates for online stores while giving shoppers flexible, interest-free payment options.
1. Merchant Fees (Primary Revenue Source)
Klarna charges online retailers a fee every time a customer uses Klarna at checkout.
Merchants happily pay this because Klarna:
- Increases order conversion
- Boosts average order value
- Reduces cart abandonment
This fee model is the backbone of Klarna’s multi-billion-dollar revenue.
2. Consumer Fees (Late Fees Only)
Klarna does not charge interest on Pay-in-4 or Pay-later products.
However, late or missed payments result in small fixed fees.
These are regulated and form a minor revenue stream.
3. Interchange Fees (Klarna Card)
Users with the Klarna Card generate interchange fees (merchant transaction fees), similar to how credit and debit cards earn revenue.
4. Subscription Products
Klarna offers optional upgraded services such as:
- Purchase protection
- Premium Klarna Card versions
These bring recurring subscription revenue.
5. Interest on Financing Plans
For longer-term financing (6–36 months), Klarna charges interest.
This is used in large purchases such as electronics, furniture, fashion, and travel.
6. Advertising & Brand Promotion (Klarna Ads)
Merchants pay Klarna to promote their products inside the Klarna Shopping App, which now acts as a discovery marketplace.
This advertising division has become one of Klarna’s fastest-growing revenue streams in 2025.
7. Data & Checkout Solutions
Klarna sells fraud prevention, risk scoring, and checkout optimization tools to global merchants — a B2B revenue stream powered by data analytics.
Klarna’s Financial Strength (2025 Snapshot)
- Operates in 45+ countries
- 150+ million active consumers
- Over 500,000 merchants integrated
- BNPL market share among the top globally
- One of Europe’s leading fintech unicorns
Klarna’s business model succeeds because it benefits both sides:
Shoppers get flexibility, and businesses get higher sales.

Key Features That Make Klarna Successful
Klarna’s global rise comes from its ability to blend convenience, flexibility, and trust into every shopping experience. Each feature is designed to reduce friction for shoppers while increasing conversion for merchants.

2. Pay Later (30-Day Billing)
Users can receive their order first and pay later within 30 days. This reduces hesitation during checkout and boosts merchant sales by lowering upfront commitment.
3. Klarna Card
A physical and virtual card that lets users shop anywhere with Pay in 4. It connects directly to the Klarna app for repayment scheduling and spending control.
4. One-Time Virtual Cards
Users generate temporary cards for online purchases. These cards support BNPL payments even on sites not partnered with Klarna.
5. Shopping Browser Extension
The Chrome/Edge extension brings Klarna’s installment options to nearly any website. It also auto-applies coupons and cashback deals, improving user savings.
6. Rewards Club
Klarna’s loyalty program gives users points (Vibe points) for every purchase. These points can be redeemed for gift cards from partner brands.
7. Price Drop Alerts
Users can track products from various stores within the app. Klarna notifies them when prices fall, helping users shop at the best moment.
