Activate Sezzle for "Buy Now, Pay Later" Customer Payments

Corey Wright

Sezzle is a popular "buy now, pay later" option that allows your shoppers to purchase items today and make four interest-free payments over a six-week period.

Sezzle charges shops a percentage of the total order amount to keep the option interest-free to customers. While shoppers will pay for their orders from their account page or your mobile app, payments run through Sezzle—CommentSold does not hold any of these funds.

Sezzle is one of several payment gateways you can connect to CommentSold. Learn about other available payment gateways here.

How Sezzle Benefits Your Shop

Allow shoppers to split payments into four installments, which encourages them to place larger orders.
Increase revenue and overall customer retention. CommentSold data shows customers are 21% more likely to make repeat purchases from a shop using Sezzle versus other payment processors.
Receive a customer's total order amount, less the fee deducted by Sezzle, immediately.

Troubleshooting Errors

Expand this section to know about the common errors and how to troubleshoot them.

Here are some common errors and their resolutions:

Customer received email/error that order was cancelled
Just like Paypal & Klarna, when a customer uses Sezzle, they are taken to an external checkout page to complete their order. If the customer does not check out in time, the connection may time out for security purposes. This initial authorization may show as a pending charge in the customer’s bank account. Since the order was not created, the pending charge will fall off their account after a day or so. The customer will not be charged.

Customer's card is declined but they have funds available

The customer is likely using a Chase credit card. Effective October 10, 2024, customers will not be able to use Chase credit cards with Sezzle. Payments to any installment plans (e.g., Klarna, AfterPay, etc.) using a Chase credit card will be declined.

Declined Merchant Application
If your Sezzle Merchant Account application was denied, you will receive an email explaining the general reason.

Sezzle requires a website in order to consider allowing a boutique to use their service, so you will need to have the Webstore enabled in CommentSold.

If your webstore is enabled, contact Sezzle Support for more information.
