How Do I Add Sezzle to Shopify?
Short answer
Install the Sezzle Payments app from the Shopify App Store, sign up for a Sezzle merchant account to connect it, then turn on Sezzle's payment messaging so shoppers see installment pricing on product and cart pages. Sezzle pays you the order total upfront and charges a fee set in your merchant contract.
Sezzle is a buy now, pay later provider popular with shoppers who want to split purchases into smaller payments. Adding it to Shopify is quick, and the important part comes after installation: making sure shoppers actually see it.
How Sezzle works
From the Sezzle Payments listing on the Shopify App Store:
- The shopper pays 25% at checkout.
- The remaining three payments are debited automatically every two weeks.
- Sezzle pays the merchant the full amount upfront and takes on fraud and non-payment risk.
- Charges are in USD, and eligibility criteria apply.
The merchant pays a fee per transaction. Your exact rate depends on your Sezzle contract and volume.
Step 1: Install the app
- Open the Shopify App Store and search for Sezzle Payments.
- Click Install and select your store.
- Review and approve the permissions.
Step 2: Create your Sezzle merchant account
The app prompts you to sign up with Sezzle. You'll provide business information and bank details so Sezzle can pay out orders. Sezzle reviews applications, and certain product categories may be restricted.
Step 3: Activate Sezzle at checkout
Once your account is approved, follow the in-app instructions to activate Sezzle as a payment option. Then check Settings > Payments in your Shopify admin to confirm it's listed and active.
Step 4: Turn on payment messaging
The app includes payment messages that display something like "or 4 interest-free payments of $25 with Sezzle" near the price. Add these to:
- Product pages, under the price
- Cart page or cart drawer
- Optionally a banner on the homepage
Most modern Shopify themes let you place these as app blocks in the theme editor (Online Store > Themes > Customize). Without messaging, shoppers often don't discover the option until checkout, if at all.
Step 5: Test
Run a test order or at least go to checkout to confirm Sezzle appears. Try carts at different values, since BNPL providers set order limits.
Should you add Sezzle?
Consider:
Your average order value. BNPL shines when an order is big enough that splitting it matters, but not so big that it exceeds limits. Fashion, beauty, fitness gear and home décor are common fits.
Your customers. If your audience is younger or budget-conscious, they're more likely to use BNPL. Check whether customers have asked for it.
Fees vs. lift. BNPL fees are higher than standard card processing. The option pays off only if it increases conversion or order size enough to cover the difference.
Checkout clutter. Offering Sezzle, Afterpay, Klarna and Shop Pay Installments at once can overwhelm shoppers. One or two well-known options are usually enough.
Sezzle vs Afterpay
Both offer four-payment plans and pay merchants upfront. The practical differences are eligibility, fees in your agreement, brand recognition among your customers and how each integrates with Shopify. Afterpay's Shopify integration requires a US store address and USD currency. See our Afterpay setup guide for comparison.
Explaining Sezzle to customers
Some shoppers have never used BNPL, so a short explanation removes hesitation. Add a line to your FAQ page covering how the four payments work, that approval happens at checkout, and that questions about the payment schedule go to Sezzle rather than your store. Make sure your customer service team knows how refunds work for Sezzle orders: when you refund in Shopify, the provider adjusts the shopper's remaining installments. Clear answers here prevent confused emails and chargebacks later.
Tracking the results
After launch, watch:
- Share of orders paid with Sezzle
- Conversion rate on product pages showing messaging
- Average order value for Sezzle orders vs card orders
Give it two or three months before deciding. If you need a refresher on measuring conversion properly, see what is a good conversion rate for ecommerce.
