Credit limits
Klarna

To view your estimated spending amount, you can take a look at your Purchase Power in the app. This amount is subject to change and based on factors like your outstanding balance and your payment history with Klarna.
Sezzle
Sezzle does have spending limits, but there are rules and restrictions.
- The Sezzle system automatically determines your spending limit on a case-by-case basis.
- The spending limit approval process depends on how long you’ve been a Sezzle customer, your credit history pulled from a soft credit check, and your order and payment history with Sezzle.
- The Sezzle support team cannot tell you your spending limit or manually increase spending limits.
- You can view your spending limit in one of two ways: joining Sezzle Up or using a bank account as your default payment method.
- Your spending limit can vary by brand.
- If you are unable to make a purchase because of a low spending limit, you may need to lower the amount you spend on a purchase or make payments on outstanding items.
Fees
Klarna
If a payment does not go through, Klarna will charge you a late fee up to $7. Klarna will then try to reprocess the payment, and if it fails again, the amount will be added to your next payment.
You should note that if you do not make on-time payments, you will not be able to continue using Klarna until you’ve settled up your outstanding balance. Klarna will also report your late or missing payments to the credit bureaus, which can negatively affect your credit history and credit score.
Sezzle
Sezzle does not charge annual fees. However, Sezzle does charge fees for late payments, failed payments, rescheduling more than one payment per order, reactivating an account after it has been deactivated, and paying by card rather than directly through a bank account.
Credit check
Klarna and Sezzle do not do hard credit checks when you make a purchase using the service. Both providers run a soft credit check to get a sense of your credit history, Soft credit checks provide enough information to give the BNPL services a sense of your creditworthiness without penalizing your credit score with a hard inquiry.
However, Sezzle offers a feature called Sezzle Up. With Sezzle Up, you authorize the provider to report your payment history to the credit bureaus. If you make on-time, full payments to the provider, this can boost your credit history and credit score. But if you make late payments or miss them entirely, this can damage your credit.

Frequently Asked Questions
Klarna vs. Sezzle: Which is better?
It is not a matter of which Buy Now Pay Later service is better. Rather, it is important to consider whether BNPL is the right choice for you at all.
The service that you use as a customer depends on which merchant or company you are purchasing from and in what country you are located. All brick-and-mortar and online retailers don’t partner with all BNPL companies.
Before deciding to make a purchase with BNPL, it’s important to consider: how much you really want or need the product or service, your budget, and cash flow.
What happens if I never repay Klarna or Sezzle?
If you fail to make your scheduled repayments through Klarna, Sezzle, or any other BNPL providers, you can run into credit and financial issues.
Klarna and Sezzle both charge you late fees if you miss a payment or your payment fails. Your account may also get disabled, meaning that you would not be able to make future purchases with the BNPL service.
All Klarna accounts get reported to the bureaus, so if you have late or missing payments, it can negatively impact your credit history and credit score. Similarly, if you use Sezzle Up, the provider will report your late or missed payments to the bureaus, which can negatively impact your credit report and score.
In order to avoid late fees or other hidden fees, it is important that you carefully consider whether or not it is financially responsible to use Buy Now Pay Later. If you do decide to purchase something with BNPL, you should create a payment plan that works for your cash flow and ensures you will not be negatively financially affected by late or missed payments.
Are Klarna and Sezzle legit?
Klarna and Sezzle are both legitimate and secure services. Both keep customer data safe and sound and act much the same as credit cards, personal loans, and payday loans except with shorter-term repayment plans.
