Affirm: United States / Canada's bnpl
Affirm is a bnpl used in United States / Canada. US BNPL and instalment lender offering both Pay in 4 and longer-tenor financing with transparent APR. Strong US brand recognition; expanding in Canada. This page covers how the flow works, where consumers use it, and which merchants should accept it.
How the Affirm flow works
At checkout the shopper picks Affirm and provides basic information for a soft-pull underwrite. Affirm offers a menu of options depending on cart size — from Pay in 4 (interest-free) to 3-, 6-, 12- or 24-month instalment loans with disclosed APR.
The shopper picks a plan and Affirm pays the merchant in full upfront, taking on all credit risk.
Repayments are made monthly via debit card, ACH or Affirm's own card. Interest and terms are shown up front — there are no compounding fees or late charges on the core product.
Affirm is prominent in higher-ticket categories where a 12–24 month plan converts better than credit card revolving balances.
Typical use cases
- High-AOV categories: furniture, mattresses, electronics, fitness equipment, home improvement, travel.
- Merchants wanting a US-native BNPL alongside card checkout.
- Any category where transparent instalment financing outperforms credit-card revolving as a purchase-financing option.
Consumer reach
Strong US brand recognition; expanding in Canada.
Skews slightly older and higher-ticket than pay-in-4-only competitors.
Who should accept Affirm
- US merchants selling higher-ticket goods where financing meaningfully lifts conversion.
- Brands preferring a transparent APR product over deferred/late-fee BNPL models.

Which countries does Affirm cover?
Affirm is recorded against United States / Canada in the North America region, which is the market where its consumer reach is meaningful for merchants. Cross-border acceptance depends on the acquirer or merchant-of-record you use rather than on the rail itself. The United States / Canada country hub lists every other alternative and local method tracked for that market alongside Affirm.
What does Affirm cost a merchant?
Pricing for Affirm is not a single published number: it moves with monthly volume, vertical, entity type and whether you connect through a direct acquirer or an aggregator. Effective pricing bands per provider, plus the fixed-fee and FX components that sit alongside the headline rate, are part of the founding-partner dataset rather than this public United States / Canada profile.
Which PSPs and aggregators give access to Affirm?
Access to Affirm runs either through an acquirer with a direct rail connection or through an aggregator reselling a partner's connection, and the two differ in reliability and reporting. The list of providers processing Affirm in United States / Canada today, whether each is direct or resold, and where onboarding is currently restricted sits in the founding-partner PSP coverage matrix.
Is Affirm available for High-AOV categories: furniture, mattresses, electronics, fitness equipment, home improvement, travel?
Yes. That is one of the documented use cases for Affirm in United States / Canada: High-AOV categories: furniture, mattresses, electronics, fitness equipment, home improvement, travel. Vertical eligibility is ultimately set by the provider you onboard with, not by the rail, so regulated categories such as gambling, crypto and adult content are commonly excluded even where the bnpl itself supports the flow. Confirm the restriction list with your acquirer.
What are the settlement time and currency for Affirm?
Affirm is a bnpl, so the payer-side confirmation and the merchant-side payout are separate events with different timing. Settlement windows, cut-off behaviour outside scheme hours, the payout currency, and the realistic timeline to sweep funds out of United States / Canada are documented in the operational section of this profile, available to Payment Methods List founding partners.
