Sezzle vs Afterpay for US merchants

VS
Sezzle

Sezzle

B-

Sezzle is a Minneapolis buy-now-pay-later provider founded in 2016; Charlie Youakim, Paul Paradis and Killian Brackey are the co-founders named most consistently, though accounts of the full founding team differ. It began as a next-business-day ACH product and pivoted to instalments in 2017, listed on the Australian Securities Exchange on 30 July 2019, began trading on Nasdaq as SEZL on 17 August 2023 and left the ASX in January 2024. For the quarter ended 30 June 2026 it reported gross merchandise volume of $1.3 billion, up 37.9% year on year, total revenue of $149.7 million, up 51.7%, and net income of $40.8 million. For a merchant the bargain is the standard BNPL one but unusually cleanly stated: the shopper pays Sezzle a down payment, Sezzle pays you the full order value less your merchant rate, and Sezzle then carries both the fraud risk and the repayment risk for the six weeks that follow. What Sezzle does not do is tell you what that costs. There is no published merchant rate anywhere on its site — the fee is in the agreement you sign — and there are three separate ancillary charges most merchants only meet after signing.

Afterpay

Afterpay

B

Afterpay is the buy-now-pay-later network founded in Sydney in October 2014 by Nick Molnar and Anthony Eisen, and owned since January 2022 by Block, Inc. — the deal was announced in August 2021 at a headline US$29 billion and completed on far less, reported at roughly US$14 billion in Class A shares, because Block's own share price had fallen in the interim. For a merchant, the proposition is straightforward: offer shoppers four interest-free instalments over six weeks, or a monthly plan over six or twelve months, get paid up front rather than waiting for the customer to finish paying, and let Afterpay carry the fraud and non-payment risk. In exchange the merchant pays a commission Afterpay does not publish — third-party reviewers consistently report a range around 4% to 6% plus roughly $0.30 per transaction, several times the cost of taking the same sale on a card. Afterpay's own merchant marketing claims a 58% increase in average order value among accepting merchants and $8.6 billion of incremental US sales delivered over the preceding twelve months. Under Block, the product has increasingly become a Cash App feature rather than a standalone checkout button: Afterpay Post-Purchase and, from 2026, Afterpay Pre-Purchase let Cash App Card holders convert everyday card spend into instalments at any merchant, whether or not that merchant has ever signed an Afterpay agreement.

Overview

This is a US comparison of two buy-now-pay-later networks that do the same job for a merchant: the shopper splits the purchase into instalments, the merchant is paid up front for the whole order less a commission, and the provider carries the fraud and repayment risk. Neither publishes that commission. Sezzle's merchant support says only that a set percentage plus a small processing fee applies and that the figures are in the agreement you sign; Afterpay's business page promises simple, transparent pricing and prints no price. Where they part company is everything around the commission. Sezzle now publishes its ancillary fees and two of the amounts - a $15 monthly minimum below $300 of order volume, a refund fee (amount unstated) when a refund cannot be drawn from your refund reserve, and a monthly inactive-account fee of 10% of the balance or $1,000, whichever is greater, on dormant accounts holding funds - and documents a common three-business-day settlement. Afterpay publishes none of that, assigns each merchant a settlement period of one to five business days in its agreement, but is owned by Block, is native to Square and Cash App, serves five countries under one brand, and its Pay in 4 is interest-free with no fees for the shopper at partner brands, where Sezzle's Pay in 4 can now carry a service fee shown at checkout. Payment Review grades Sezzle B- and Afterpay B.

Key Takeaways

  • ✓Neither publishes its merchant commission; Sezzle's support pages say it is a set percentage plus a small processing fee set in your agreement, and Afterpay prints no figure at all, so both are a sales conversation before they are a price.
  • ✓Sezzle publishes its ancillary fees and two of the amounts - a $15 monthly minimum below $300 of volume, a refund fee outside the refund reserve, and an inactive-account fee of the greater of 10% of balance or $1,000 - where Afterpay publishes no monthly fee and no ancillary schedule.
  • ✓Afterpay is cheaper for the shopper: Pay in 4 is interest-free with no fees when paid on time at partner brands, whereas Sezzle's Pay in 4 can carry a service fee shown at checkout, illustrated on its own site as $7.49 on a $300 order.
  • ✓Afterpay is native to Square and Cash App and serves the US, Australia, New Zealand, the UK and Canada under one brand; Sezzle's shoppers are US and Canadian, and its in-store product needs a qualifying US merchant.
  • ✓Sezzle documents a common settlement period of three business days; Afterpay's marketing says one to two, while its merchant help centre says a period between one and five business days is assigned in your agreement.

Sezzle

Sezzle suits a US or Canadian online retailer that wants the ancillary fees in writing before it signs, reaches a younger or thinner-file shopper base that a second mainstream BNPL button would not, and can clear $300 of Sezzle volume a month so the minimum fee never bites.

Afterpay

Afterpay suits a merchant already selling through Square or reaching Cash App users, a retailer for whom a fee-free shopper experience matters to conversion, and anyone selling into Australia, New Zealand, the UK or Canada as well as the US.

The Verdict

It Depends on Your Needs

Why?

Neither will tell you what it costs before a sales conversation, so the decision turns on what surrounds the commission. Afterpay wins on the shopper side and on reach: its Pay in 4 is fee-free at partner brands where Sezzle's can carry a service fee at checkout, it is native to Square and Cash App, and it serves five countries under one brand - which is why it holds the higher grade. Sezzle wins on what it puts in writing: the $15 minimum, the refund fee and the inactive-account fee are now published, the common three-day settlement is documented, and an interest plan exists for merchants who can leave funds with it. A US retailer on Square, or one selling into Australia or the UK, should start with Afterpay. A US or Canadian store that wants every ancillary charge on the page before signing, or that is chasing a younger, thinner-file shopper a second mainstream button would not add, should look at Sezzle - and read the inactive-account terms before it does.

Merchant cost and transparency

Merchant cost and transparency: Sezzle compared with Afterpay.
FeatureSezzleAfterpay
Published merchant rate
None; a set percentage plus a small processing fee, set in the merchant agreement
None; commission is quoted per merchant
Sezzle's merchant support says the order processing fee is 'a set percentage of each order and a small processing fee', that the figures are in the agreement signed at application, and that the rate 'is determined by the type of products you offer, how long your store has been in business, and other factors'. Afterpay's US business page says 'simple, transparent pricing' and prints no number. Third-party reviewers report a range of roughly 4% to 6% plus about 30 cents for Afterpay; that is attributed reporting, not a published price, and we could not find a range for Sezzle from any source we would stand behind.
Monthly or minimum fee
$15 a month if order volume is under $300 in the 30 days before your billing date
None published; free sign-up, no monthly fee
Winner
Sezzle's help centre now states the amount: 'A $15 monthly fee for merchants with less than $300 USD of order processing volume within a 30-day period'. The billing date is the approval date and every 30 days after. Afterpay's business page advertises free sign-up and no monthly fee; its ancillary terms are in the merchant agreement.
Other documented fees
Refund fee when a refund cannot come from your refund reserve; inactive-account fee of the greater of 10% of balance or $1,000 a month
None published; refund and reserve terms are in the merchant agreement
Sezzle's inactive-account fee applies to a merchant that has neither captured an order nor initiated settlement for 90 or more consecutive days while holding a positive balance, and is deducted monthly until the account is reactivated or the balance is zero. Withdrawing the balance avoids it. Afterpay's Australian merchant-fees page says the fee is a fixed amount plus a percentage set in the agreement; how much commission returns on a refund is a contract term at both.

Afterpay is Block's own BNPL and is switched on inside Square rather than integrated, and Afterpay's US business page lists Square among its payment service providers; Sezzle is not on that list.

US online store selling to a younger or thinner-file audience

Sezzle runs only a soft credit check and, as the site's Sezzle review notes, reaches a younger, thinner-file shopper base, so the volume it brings is more likely to be incremental to a store that already offers a mainstream BNPL button; its 27-platform integration list covers the usual carts.

Merchant selling into Australia, New Zealand, the UK or Canada as well as the US

Afterpay runs all five markets under one brand and one relationship; Sezzle's shoppers are US and Canadian only.

Low-volume or seasonal merchant

Neither. Sezzle charges $15 a month below $300 of volume and a steep fee on a dormant account holding funds; Afterpay's commission at any reported figure is several times a card rate. A merchant that will process a handful of BNPL orders a month is paying to offer a button almost nobody uses.

Merchant that wants the ancillary fees in writing before signing

Sezzle's help centre now prints the minimum fee, the refund-fee trigger and the inactive-account fee; Afterpay leaves refund, reserve and settlement terms to the merchant agreement and its own pages disagree on settlement timing.

Frequently Asked Questions

Common questions about this comparison

Neither publishes its commission. Sezzle's merchant support says a set percentage of each order plus a small processing fee applies and that the figures are in the agreement you sign; Afterpay's business page prints no price, and third-party reviewers report a range of roughly 4% to 6% plus about 30 cents. Sezzle does publish its ancillary fees: a $15 monthly minimum if you process under $300 in a 30-day period, a refund fee when a refund cannot come from your refund reserve, and an inactive-account fee on dormant accounts holding a balance. Ask both for the rate, the refund treatment and any reserve as three separate numbers.

Afterpay, at partner brands. Its Pay in 4 is interest-free with no fees when instalments are paid on time. Sezzle's Pay in 4 may carry a service fee, shown at checkout, that varies with the order amount - its own example is $7.49 on a $300 order - and its Pay in 5 is fee-free only with a paid Sezzle Premium subscription. Sezzle says fees apply with certain merchants, so ask what your shoppers will see.

Sezzle pays the full order less its fee into your Sezzle account when the order is placed and sends it to your bank on a settlement period set by your application, most commonly three business days. Afterpay's marketing says one to two business days, but its merchant help centre says a settlement period of between one and five business days is assigned in your agreement. Confirm your period in writing with either.

Both, through a virtual card in the shopper's phone wallet. Sezzle offers the Sezzle Virtual Card in Apple Pay or Google Pay for qualifying US merchants; Afterpay offers the Afterpay Card in Apple Wallet or Google Wallet plus point-of-sale integrations, including Square. In both cases the sale arrives at your terminal as an ordinary Visa payment, so your card-processing rate applies as well as the BNPL commission.

Yes, and many merchants do; the platforms' plug-ins coexist at checkout. The case for a second button is incremental shoppers: Sezzle runs only a soft credit check and reaches a younger, thinner-file base, while Afterpay's is larger and reaches Cash App users. Keep an eye on Sezzle's $15 monthly minimum, which applies if the second button processes under $300 a month.

Sezzle is an independent, Minneapolis-based company listed on Nasdaq as SEZL since August 2023. Afterpay has been owned by Block, Inc. - the parent of Square and Cash App - since January 2022.
