Sezzle is reliable overall but not incident-free: StatusBird's independent monitoring recorded 99.95% availability with 1 major incident totaling 1 hour 2 minutes of downtime in the last 90 days.
Numbers alone do not tell you whether to worry, so this post also covers what actually breaks when Sezzle has problems and how to get warned early.
What is Sezzle?
Sezzle is a buy now, pay later payment provider that lets shoppers split a purchase into interest-free installments, typically four payments over six weeks. Online stores add Sezzle as a payment option at checkout through apps or gateway integrations on platforms like Shopify, BigCommerce, and WooCommerce. Sezzle pays the merchant upfront and collects the installments from the customer.

What happens to your store when Sezzle goes down?
When Sezzle is down, the Sezzle button at checkout either disappears, hangs, or returns an error after the shopper is redirected to Sezzle to approve the installment plan. Shoppers who specifically wanted to split payments abandon their carts, and orders that were mid-approval when the outage hit can end up stuck in a pending state. The rest of the checkout usually keeps working, so the damage is concentrated on customers who rely on installment payments for larger orders.
Typical symptoms during a Sezzle outage:
- Sezzle payment option missing or greyed out at checkout
- Shoppers redirected to Sezzle see a spinner or error page instead of the approval flow
- Orders paid via Sezzle stuck in pending or payment authorization status
- Sezzle merchant dashboard fails to load or shows login errors
- Spike in abandoned checkouts on higher-value carts

Frequently asked questions
Will I still get paid for Sezzle orders that were placed right before the outage?
Orders that Sezzle fully approved before the outage are normally funded as usual, since Sezzle pays merchants upfront on approved transactions. Orders that were mid-approval may fail or stay pending, so check each one in your Sezzle merchant dashboard after recovery before fulfilling it.
Can customers still check out on my store while Sezzle is down?
Yes, in almost all cases. Sezzle is one payment method among several, so credit cards, PayPal, and wallet payments keep working. Only shoppers who select Sezzle will hit errors, so make sure your other gateways are visible and consider a banner pointing customers to them.
How this data is measured
StatusBird checks Sezzle's status every 2 minutes, around the clock, independently of the vendor. The availability figure counts major and critical outages only; minor degradation is excluded so numbers are not skewed by vendors that report small blips near-continuously. Grades run from A+ to F. See the live numbers on the Sezzle reliability page and current status on the Sezzle status page, or browse all 84 service grades.
Know before your customers do
StatusBird monitors Sezzle and 83 other services online stores depend on, plus your own storefront, every 2 minutes. When something goes down you get an SMS, email, or Slack alert with plain-English context, usually before the official status page catches up.
