Fee and volume check
Your likely Sezzle rate, the $300 monthly threshold, and refund costs estimated before you sign up.
The Problem
Sezzle Works, but Payouts Don't Add Up
Sezzle is simple to switch on. The trouble shows up later, in settlements that combine days, refunds that come out of payouts, and fees nobody planned for.
01 · Payout gaps
Your settlement lands at $1,275 when you expected $1,700.
Each payout gets explained line by line, so it matches your orders.
02 · Slow-month fees
A slow month under $300 in orders brings a $15 fee.
Your order volume gets checked against Sezzle's fees before launch.
03 · Refund fees
Refunds charged to your card carry their own fee.
A refund reserve covers returns, which avoids Sezzle's refund fee.
04 · Hidden option
Your pages show only the full price, so few notice Sezzle.
Sezzle's widget sits under prices on your product pages.
Your Monday settlement lands at $1,275 when you expected $1,700, because Sezzle combined the weekend's orders, took its fees, and subtracted two refunds. A slow month under $300 in Sezzle orders brings a $15 account fee. Refunds charged to the card on file carry their own fee, because nobody set up a refund reserve. And your product pages still show only the full price, so few shoppers know Sezzle is there.
We start with your order volume and refund pattern, then set up Sezzle so the numbers make sense before launch. We connect the app or plugin, add Sezzle's widget to your product pages, create a refund reserve, and walk you through reading settlements. Your shoppers see 25% due today, and you see payouts you can reconcile.
Settlements you can read
Weekend orders, fees, and refunds explained line by line, so each payout matches your orders.
Refund reserve in place
Refunds come from a reserve instead of your card, which avoids Sezzle's refund fee.
Widget where shoppers decide
Sezzle's payment widget sits under prices on product pages, not only inside checkout.
Our Sezzle Setup Process
From Fee Check to Live Sezzle
You see your expected fees, where the widget sits, and how settlements will read before any shopper pays with Sezzle.
We look at your monthly volume, average order, refund rate, and platform, then estimate how Sezzle's fees and minimums apply. Then you get a fixed quote, unless the free app alone already covers your store.
What's Included
Everything in a Sezzle Merchant Setup
Every setup covers the fee check, app or plugin setup, the product page widget, refund handling, real order tests, and a handover your team can follow.

What Our Clients Say
What Clients Say After Launch
Feedback from ecommerce teams we have built checkouts, payments, and integrations for.
We were getting plenty of traffic, but far too many people were leaving at checkout. The buying process had simply become too complicated. The team took the time to understand where customers were dropping off, then rebuilt the checkout flow and cleaned up the shopping experience. What I really appreciated was that they didn’t just make the store look better, they actually solved the problems that were costing us sales. The whole store feels faster, simpler, and much easier to buy from now. Exactly what we needed.
We had a different kind of problem. People were visiting the store, adding products to their carts, and then disappearing before they finished the order. We had tried a few apps and made changes here and there, but nothing really seemed to solve the bigger issue. The team went through the shopping experience with us and pointed out things we hadn't really noticed ourselves. They cleaned up the cart and checkout flow, made the mobile experience much smoother, and helped us make the store feel easier to shop. I’m not going to pretend we fixed everything overnight, but it finally feels like the store is helping the sale instead of getting in the way of it.
Our old store was making it way too difficult for people to find products. We had a large catalogue, but the search, filters, and mobile navigation were frustrating customers. The team completely changed how the store handled product discovery and made the experience much easier to use on mobile. I was especially impressed by how much thought went into the customer journey rather than just the visual design. They understood what we were trying to achieve and turned it into a store that actually feels built for our customers. We’re genuinely proud of the result.

Why Growing Stores Trust Our Sezzle Setups
Sezzle only helps when shoppers see it and your payouts make sense. These are the habits we bring to every Sezzle setup, on any platform.
Fees planned before launch
Sezzle adds a $15 monthly fee when order volume stays under $300 in 30 days. We check your numbers first, so that fee doesn't surprise you later.
Refunds from a reserve
Refunds charged to your card on file carry a Sezzle fee. We add a refund reserve, so returns come out of your Sezzle balance instead.
Settlements read line by line
Sezzle combines orders with the same settlement date, then subtracts fees and refunds. We walk through your first settlements, so every payout ties back to real orders.
Widget where prices sit
Shoppers only choose Sezzle if they notice it. We put the widget under your product prices, styled to your theme, so the smaller first payment is visible.
Honest about the free app
If Sezzle's free app already covers a simple store, we'll say it plainly on the first call. You won't pay us to press Install.
Your Sezzle account, your payouts
Your merchant account, bank details, and settlements stay under your business. We hand you every login back once the project closes.

Good fit
US and Canadian stores with younger shoppers
Your shoppers are younger and budget-minded, and paying 25% today instead of $150 is what gets them to check out.
Shopify stores adding Sezzle
You want Sezzle for Shopify installed with the payment option, a styled product page widget, and a tested refund, not just a switched-on app.
WooCommerce and BigCommerce stores
Your store runs on WooCommerce or BigCommerce, and you want Sezzle's plugin set up and tested against your theme and checkout.
Low-volume or seasonal stores
Your sales dip below $300 in some months, so you want Sezzle's $15 minimum fee and refund fees planned for upfront.
Custom-built storefronts
You run a custom checkout and need Sezzle through its public API, which starts with an application for API keys.
Not a fit
Outside the US and Canada
Most of your shoppers live outside the US and Canada. Sezzle only serves those two markets, so the Klarna Integration page is a better place to start.
High-ticket items
You sell high-ticket items worth several thousand dollars. Monthly financing suits those better, so see our Affirm Integration service.
Comparing several options
You want several pay-later options compared before choosing one. Our Buy Now Pay Later Integration service starts with that comparison.
Default Shopify setup
You're on Shopify and only need Sezzle switched on with default messaging. Sezzle's app costs nothing to install, so our $300 setup is more help than a simple store needs.

Sezzle charges a set percentage on every order, plus a small processing fee. Its approvals team sets your rate at sign-up, based on your products and time in business. A $15 monthly fee applies when order volume stays under $300 in 30 days, and card-on-file refunds carry a fee. Signing up is free.
Our Sezzle setup starts at $300 for one Shopify, WooCommerce, or BigCommerce store, with the widget, refund handling, and tested orders. Adding the widget across your catalog and a second store costs $800, and a custom API build starts at $1,850. You get a fixed quote after a free fee check.
Once Sezzle approves you, a Shopify, WooCommerce, or BigCommerce setup takes 3 to 5 business days, mostly for widget styling and order tests. A second store adds a few days. A custom build on Sezzle's API needs 2 to 3 weeks, starting with an API key application.
With Sezzle for business, Sezzle pays you for the full order, less its fees, and takes on the fraud and repayment risk. Your shopper pays 25% at checkout and the rest in three payments every two weeks. Funds usually reach your bank in 3 business days, and same-day orders settle together.
You apply with Sezzle, wait for its approvals team to set your rate, then install Sezzle's app or plugin and link it to your account. After that, add the widget to product pages, open a refund reserve, and place a test order you refund before launch.
Sezzle for Shopify installs from the Shopify App Store and is free to install, with fees billed in USD under your Sezzle contract. Once it's connected, shoppers can pick Sezzle when they pay. Its payment messages show on product pages, and we style them so they fit your theme.
For Sezzle, WooCommerce stores use Sezzle's official plugin, connected with the API keys from your Sezzle merchant account. It adds Sezzle at checkout and a widget near product prices. We test it in your current checkout, with real orders and refunds, before your launch date.
Sezzle works for shoppers in the United States and Canada. If most of your customers are elsewhere, Klarna or Afterpay covers more markets, and our Buy Now Pay Later Integration service compares them. Sezzle also notes that settlements to banks outside the US can take longer to arrive.
It can, mainly on mid-priced items where paying 25% today feels easier than paying in full. We don't forecast a number, because it varies with your products and shoppers. Our Full Setup adds GA4 events, so you can see how Sezzle orders stack up against card payments in your reports.
Yes, Sezzle is safe for merchants: it pays you upfront and covers all fraud and repayment risk, per its merchant help center. Sezzle Inc. is listed on Nasdaq under SEZL. Your store connects through Sezzle's official app, plugin, or API, so shoppers' payment details stay with Sezzle.
