Comparison · Updated October 24, 2026

Affirm is a buy-now-pay-later provider founded in 2012 by Max Levchin, Nathan Gettings, Jeffrey Kaditz and Alex Rampell, headquartered at 221 Main Street in San Francisco and listed on Nasdaq as AFRM since January 2021. For the fiscal year ended 30 June 2026 it reported $50.2 billion of gross merchandise volume, up 37%, across approximately 571,000 active merchants and 27.8 million active consumers. Merchants integrate Affirm as a checkout option, Affirm underwrites and funds the consumer, and the merchant is paid in full up front minus a fee. Two things make it materially different from card acceptance: Affirm bears the consumer fraud risk on transactions it approves, and the merchant fee is several times a card rate — third-party surveys of mid-market merchants report 2% to 8%, while Affirm's own filings put blended merchant network revenue at 2.3% of GMV in FY2026. Its BBB profile is A+ and accredited; its consumer Trustpilot score is 1.7 across roughly 7,700 reviews.

Splitit is an Atlanta-headquartered installment provider that works differently from every other name in buy-now-pay-later. There is no loan, no application and no new account: the shopper pays with a credit card they already hold, Splitit places an authorization on the card for the full purchase amount, and the balance is charged down in monthly or bi-weekly instalments against that same card's existing credit line. Because no credit is being extended, nobody is declined for credit — Splitit advertises approval above 85% against 30–40% for conventional BNPL, and an average order value above $1,000 against roughly $250. The company began life as PayItSimple, rebranded in 2015, listed on the Australian Securities Exchange, then took a $50m investment commitment from Motive Partners, delisted from the ASX and went private in December 2023. It is led by chief executive Nandan Sheth and registered in the United States as Splitit USA Inc., NMLS #2314339. Merchant pricing is quoted rather than published, across four plan tiers whose consumer APR ranges from 0% to 35.99% depending on which side absorbs the cost.
We compare the two for a US merchant selling to US shoppers, using each company's published terms, plan pages and help documentation as of 24 October 2026. Neither publishes a merchant fee, so the useful comparison is who carries which risk and what the shopper has to have. Affirm is a lender: it checks each shopper's eligibility, pays you the basket up front less its fee, and collects the loan itself. Its filings say it bears consumer fraud risk and generally has no recourse to the merchant; you pay back refunded amounts plus a $15 fee when a dispute goes against you. Splitit charges instalments to a credit card the shopper already holds, with no credit check, and reserves the full amount on that card for the life of the plan. Its four plans range from 0% to 35.99% consumer APR, set by which plan the merchant buys. Under its Managed model you are funded twice a week, but its terms make you liable for fraud and for card chargebacks on every instalment. Affirm finances carts of $35 to $30,000 over 30 days to 60 months; Splitit defaults to a $10,000 maximum and 12 instalments.
Choose Affirm if you want a lender to take on the shopper's credit and fraud risk, pay you every business day, and offer financing on carts from $35 up to $30,000 and terms as long as 60 months, including to shoppers without a credit card. Expect a negotiated fee that rises on 0% promotions, and Affirm's large consumer complaint load landing partly on you.
Choose Splitit if you sell high-ticket goods to customers who already have credit cards with room on them and you want instalments with no credit application, no redirect and your own branding. Budget for chargebacks and fraud staying with you, a $10,000 default cap, and a quoted fee on every plan.
Neither is better for every merchant. Affirm takes on more for you: it lends to the shopper, bears consumer fraud risk, pays out every business day and finances bigger carts over longer terms, including for shoppers who have no credit card. The cost is a negotiated fee that rises on the 0% offers that convert best, and a consumer reputation that sends some complaints your way. Splitit approves anyone with enough room on a credit card, keeps the shopper on your branded checkout and asks for no credit application. In return, fraud and chargebacks stay with you on every instalment, plans default to a $10,000 cap, and the shopper's card limit is held for the whole plan. Neither publishes a merchant price, so get quotes from both for the same basket and plan length before you decide.
| Feature | Affirm | Splitit |
|---|---|---|
| Merchant fee | Not disclosed | Not disclosed |
| Neither company publishes a merchant rate. Affirm's FY2026 10-K says merchant fees depend on the individual arrangement with each merchant, vary by loan terms and product, and are generally larger on 0% APR financing. Splitit's pricing-plans page lists four plans with a 'Get a quote' button on each and no rates. Third-party estimates of either fee are not used here. | ||
| How the fee varies | Larger on 0% APR offers | Larger on 0% APR plans (Premium) |
| Affirm: per its 10-K. Splitit: Essential offers instalments 'at no extra cost beyond processing' with the shopper paying 0–35.99% APR; Flex balances APR and merchant fee; Premium gives the shopper 0% APR and the merchant pays for it; Premium Lite also gives 0% APR but cuts the merchant's upfront funding to lower the fee. Splitit can change its fee schedule on 30 days' written notice. | ||
| Upfront funding | Full basket, less fee | Full (3 plans); partial (Premium Lite) |
| Affirm deducts merchant fees and refunds from each settlement. Splitit's pricing page shows full upfront funding on Essential, Flex and Premium and partial upfront funding on Premium Lite. Splitit also offers a Core model in which you are paid through your own processor as each instalment is collected, at a lower price, per its developer docs. | ||
| Payout timing | Business-day ACH; 1–3 business days | Mon and Thu funding; next day (Managed) |
| No winner: Affirm pays more often, but the elapsed time from sale to bank overlaps. Affirm (Business Resource Hub, live October 2026): settlement is calculated from the previous day's captures; its lending partners send the ACH on business days only, and the bank receives it within 1 to 3 business days. One Affirm help article ('Why haven't I received a settlement?', September 2026) says 2 to 4 business days instead. Friday-to-Sunday charges are paid in Monday's settlement. Splitit (Managed merchants): Monday funding covers plans activated Thursday to Sunday, Thursday funding covers Monday to Wednesday, and payment typically arrives Tuesday or Friday. | ||
Recommendations based on your business type

Affirm lends to the shopper rather than relying on an existing card limit, so it can approve customers without a big enough credit line. It finances carts up to $30,000 and terms as long as 60 months and bears consumer fraud risk.

Splitit uses the credit the shopper already has, with no application, no redirect and your own branding, and the shopper keeps their card rewards. Price in fraud and chargebacks, which stay with you.

Affirm says it bears consumer fraud risk and generally has no recourse to the merchant. Splitit's US terms make you solely responsible for fraud and liable for chargebacks, and every instalment can be charged back.
Both sell in person as well as online: Affirm through its omnichannel products and payment-provider integrations, Splitit through Splitit Go for in-person, phone and online sales. Choose on credit profile. Patients with good cards suit Splitit; patients without them need Affirm's underwriting.
Neither. Affirm will not appear for carts under $35 ($50 on some programmes), and on small baskets a BNPL fee rarely pays for itself. Splitit is built for high-value orders, and holding a card limit for a small purchase adds friction without much gain.
