Sezzle is an alternative payment platform that increases sales and basket sizes by enabling your customers to ‘buy now and pay later’ with interest-free installment plans. Sezzle collects 25% of the purchase price from the consumer at the time of purchase, but pays the merchant the full purchase price upfront, less their fee. The merchant assumes no credit or fraud risk. Sezzle then schedules three additional installments of 25% to be automatically debited from the consumer every two weeks, completely interest- and fee-free.

Sezzle is ideal for merchants that cater to young consumers, with order values typically between $50-$750, although we do accept orders up to $1,000. Sezzle increases consumers’ purchasing power and is most heavily used by those without a credit card (63% of millennials do not own a credit card), or those with a very low credit limit on their card. However, a wide range of consumers use Sezzle, both in terms of age and financial situation.

Our extension includes a payment gateway, which will enable Sezzle as a payment option in your checkout. Once a customer selects Sezzle as their payment option, they are redirected to our secure checkout, after which they are taken back to your store to view purchase details. The extension also includes a widget that displays a dynamic installment amount on your product and cart pages, which is proven to increase conversions and basket sizes.

Security & PCI: Sezzle undergoes quarterly audits for Payment Card Industry (PCI) compliance, to ensure consumers’ data is safely stored on our systems. We are currently certified up to PCI DSS Level 4.

Sezzle is a PCI DSS Level 1 certified compliant Service Provider organization. We recommend that consumers and merchants ensure they are working with a Level 1 certified compliant organization. Level 1 certification ensures that an external auditor has fully assessed the ability of the organization.

PCI DSS is a comprehensive set of requirements created by the Payment Card Industry Security Standards Council to enhance cardholder data security and to ensure the safe handling and storage of sensitive customer credit card information and data.

Sezzle’s PCI DSS responsibilities as a Service Provider are outlined in our Level 1 Report on Compliance (ROC) and our Level 1 Attestation of Compliance (AOC), as independently audited and reported by Sezzle’s Qualified Security Assessor (QSA). Sezzle’s Attestation of Compliance (AOC) is submitted to Sezzle’s acquiring bank(s).

There are 4 levels of PCI compliance:

  • Level 1: Over 6 million card transactions per year. External audit required for compliance. (Sezzle is Level 1) 
  • Level 2: 1 to 6 million transactions per year. Only a self-assessment is required for compliance. 
  • Level 3: 20,000 to 1 million transactions per year. Only a self-assessment is required for compliance. 
  • Level 4: fewer than 20,000 transactions per year. Only a self-assessment is required for compliance.
