Buy now, pay later services have changed the way people approach shopping. Instead of swiping traditional credit cards and worrying about interest, BNPL apps like Afterpay let you split purchases into four interest-free payments. With an initial payment at checkout and the rest due on set payment dates, these apps give you a way to manage expenses without falling into revolving debt. Shockingly, in 2024, BNPL services accounted for over $18 billion in holiday spending alone, proving how massive the industry is.
But Afterpay isn’t the only option. Competitors like Sezzle, Klarna, Affirm, and even PayPal Credit offer their own twists on short-term plans and flexible financing options. Some focus on rewards, others on credit building, and a few are geared toward big-ticket items. Understanding the differences is key to finding the best fit for your spending habits.
Key Takeaways
- Afterpay made BNPL mainstream with its simple four-payment model, but several competitors offer more flexibility.
- Sezzle stands out for its credit-building feature, giving users an edge that Afterpay doesn’t provide.
- Klarna offers perks like memberships, cashback, and Pay in 30, making it versatile for different budgets.
- Affirm is best for big purchases, offering longer-term financing when four installments won’t cut it.
- PayPal Credit adds convenience, but its deferred interest option requires discipline to avoid extra costs.
Why People Choose BNPL
At their best, BNPL apps offer flexible payment options that make budgeting easier. Many shoppers like the predictability of interest-free installments, especially for online shopping. These apps show you exactly how much you owe and when, removing some of the uncertainty that comes with credit card balances.
Still, each service has trade-offs. Some run a soft credit check to determine your eligibility, others have hidden fees, and each handles missed payments differently. Sezzle, Klarna, Affirm, and PayPal Credit all compete with Afterpay, but they cater to slightly different needs.
Sezzle: The Credit-Building BNPL App
If there’s one app that stands out as an alternative to Afterpay, it’s Sezzle. Like most BNPL providers, Sezzle lets you split payments into short-term, interest-free installments. The classic option is Pay in 4, but it also offers Pay in 2 and longer-term flexible repayment plans for larger orders.

Part of what makes Sezzle stand out is its Sezzle Up program, which reports positive habits (like paying on time) to the major credit bureaus. This means your responsible use of the app can actually help improve your profile over time—something Afterpay doesn’t currently offer. However, late payments can affect your score negatively, as well, so only take advantage of this opportunity if you’re a responsible spender. For younger shoppers who want the convenience of BNPL but also care about their future borrowing power, Sezzle is a strong choice.
- Pros: Interest-free for short-term plans, optional credit-building, clear terms, widely available
- Cons: Low starting spending limits, fees for rescheduling or failed payments
Klarna: Multiple Ways to Pay
Klarna competes closely with Afterpay but adds more variety. Shoppers can choose multiple payment options, including Pay in 4, Pay in 30, or long-term financing. The flexible payment plans appeal to people who want short-term predictability and those who prefer spreading costs over several months.
Klarna also has a membership model, where a small monthly fee unlocks perks like cashback and waived service charges. It integrates with Apple Pay and can be used for in-store purchases as well, making it one of the most versatile BNPL providers.
- Pros: Several repayment structures, perks through membership, broad acceptance
- Cons: Spending limits are inconsistent, long-term financing carries interest charges
Affirm: Longer-Term Financing
Affirm sets itself apart from Afterpay by focusing on flexible financing options. Instead of just short-term installments, Affirm lets you pay for purchases over 3 to 60 months. For bigger-ticket items like furniture or travel, this makes it more of a hybrid between BNPL and a personal loan.
The catch is cost. While there are no late fees or surprises, Affirm does charge interest on many plans. For disciplined borrowers who want predictability and no hidden fees, Affirm works well. But for everyday items, paying interest on monthly installments can add up fast.
- Pros: No late fees, transparent pricing, useful for high-value purchases
- Cons: Often includes interest, requires credit approval for longer terms
PayPal Credit: Ubiquity with Risks
If you already use PayPal for online shopping, adding PayPal’s BNPL service is seamless. It offers Pay in 4 for smaller orders and a deferred interest option for bigger ones. You’ll see the plan right in your PayPal dashboard, making it convenient.
The downside? If you don’t pay off your balance before the promotional period ends, the deferred interest can be steep. It’s easy to miscalculate, which makes PayPal Credit riskier than something straightforward like Sezzle’s Pay in 4.
- Pros: Familiar interface, wide acceptance, integration with Google Pay
- Cons: Confusing deferred interest terms, potential high costs if not managed carefully
The Risks of BNPL
While BNPL apps feel simpler than traditional financing, they’re not without pitfalls. A soft credit check won’t hurt your score, but missed payments can still carry consequences. Some providers may block future use, add fees, or even send accounts to collections. Others, like Sezzle, can help build your credit—but only if you stay current.
For people who struggle with discipline, the appeal of split payments can lead to overspending. Even with flexible repayment plans, stacking multiple purchases across several BNPL apps can create more debt than you realize. It’s also important to remember these services aren’t designed to replace traditional credit cards, which still offer rewards, fraud protection, and travel perks.
BNPL vs. Credit Cards
Comparing BNPL to credit cards comes down to priorities. Cards often provide points, miles, and cash-back rewards, but they also carry interest rates if balances aren’t paid in full. BNPL apps like Sezzle or Afterpay don’t add revolving debt, making them appealing for smaller, planned purchases.
BNPL also gives clearer visibility into payment dates and exact payoff amounts, while cards can carry balances indefinitely. That said, cards can be safer for emergencies, while BNPL works best for predictable, budgeted purchases.
Final Thoughts: Sezzle, Klarna, and Beyond
Afterpay popularized the idea of four equal installments, but it’s not the only solution. Klarna brings flexible repayment plans and perks, Affirm leans into long-term flexible financing options, and PayPal Credit adds ubiquity. Yet Sezzle deserves special mention for combining interest-free installments with the ability to build your credit profile through Sezzle Up.
For shoppers who want convenience without hurting their future borrowing power, Sezzle stands out as one of the strongest alternatives to Afterpay.
