Shopify Affirm Integration Services

Stores lose high-ticket sales when customers cannot pay in full at checkout. Affirm solves this, but the integration path depends on the store's setup. US merchants on Shopify Payments get Affirm through Shop Pay Installments, with Adaptive Checkout presenting biweekly and monthly options for carts from $50 to $17,500. Stores outside Shop Pay need the standalone Affirm app. Shero identifies the correct path before configuration begins.

Lift in average cart size reported by Affirm merchants in 2024

Affirm reported a 70% lift in average cart sizes for merchant partners in 2024, alongside nearly 30% fewer abandoned carts compared to other BNPL providers. The cart size lift is driven by Affirm's coverage of higher-value purchases, where monthly payment terms make large-ticket items more accessible than a six-week pay-in-4 structure.

26.8M

Affirm active consumers as of March 2026

Affirm has 26.8 million active consumers and 515,000 merchant partners as of March 2026. More than 90% of its transactions come from repeat customers. For Shopify merchants, Affirm's established consumer base is a meaningful segment of buyers who already use Affirm and will specifically seek out stores that accept it.

98%

Client Retention

98% of Shero's clients stay on retainer after their project closes. Affirm's integration with Shopify requires periodic updates as Shopify changes checkout architecture, and pay-over-time messaging placements need maintaining as themes evolve.

Premier Partner

Shero holds Shopify Premier Partner status, one of fewer than 150 agencies globally. Affirm configurations on Shopify Plus, including Checkout Extensibility and Adaptive Checkout integration, require platform depth that goes beyond the standard payment app install.

The collaboration between us and Shero Commerce on the JustRite multi store site went beyond what we had hoped for. Their dedication to understanding our unique requirements has greatly enhanced our online presence.

Affirm on Shopify: Shop Pay Installments versus the direct Affirm app

There are two ways to run Affirm on Shopify: through Shop Pay Installments for stores on Shopify Payments, or via the standalone Affirm app for stores outside Shop Pay coverage. The right path depends on the store's payment stack and the markets it serves.

  • Affirm integration via Shop Pay Installments and Adaptive Checkout for US merchants on Shopify Payments
  • Standalone Affirm payment app integration for stores outside Shop Pay coverage
  • Pay-over-time messaging configuration on product pages and cart
  • Monthly and biweekly payment option configuration for Adaptive Checkout
  • Order minimum and maximum eligibility threshold setup
  • Post-launch monitoring and Affirm checkout performance reporting

Why brands work with Shero on Affirm integration

Shero selects the correct Affirm integration path for the store's payment stack before configuration begins, so Affirm's Adaptive Checkout and pay-over-time messaging work correctly from the first transaction.

01

Shop Pay Installments versus direct Affirm app: the path that fits the stack

Shop Pay Installments is the right path for US merchants on Shopify Payments who want Affirm's Adaptive Checkout with minimal additional setup. The direct Affirm app is the right path for stores not on Shopify Payments or needing Affirm branded independently of Shop Pay. Choosing the wrong path and reconfiguring after launch disrupts live checkout. Shero maps the payment stack in discovery and selects the path before any installation begins. This sits within the broader payment gateway advisory work for the store.

02

Adaptive Checkout configured to present biweekly and monthly options correctly

Affirm's Adaptive Checkout dynamically shows biweekly and monthly payment options side by side based on cart size and customer eligibility. It covers cart sizes from $50 to $17,500, making it the only Shopify BNPL integration that meaningfully addresses high-ticket purchases. Shero configures Adaptive Checkout and verifies that both payment term types display correctly across the cart size range relevant to the store's catalog.

03

Pay-over-time messaging that shows monthly amounts before checkout

Affirm's conversion impact is highest when customers see the estimated monthly or biweekly payment on product pages before they reach checkout. The Affirm Messaging app displays per-installment amounts and reframes price as a monthly cost. Shero configures messaging at product and cart levels so the payment framing is visible where purchase decisions are made.

04

Affirm is US only. Multi-market stores need separate configuration.

Affirm requires a separate Shopify store for each country of operation. A store serving both US and Canadian customers cannot run Affirm from a single storefront. Shero maps market structure before configuration to ensure Affirm is set up in the correct store context and that international markets use a compliant alternative. This connects directly to the broader Shopify Markets architecture for multi-market operations.

05

Affirm reports payment history to credit bureaus. Clear disclosure is required.

Unlike pay-in-4 providers, Affirm's monthly installment plans are point-of-sale loans that report payment history to Experian and TransUnion. Merchants are required to display compliant disclosure language about credit reporting and installment terms in their checkout and marketing. Shero configures compliant messaging as part of the integration.

06

Post-launch maintenance as Shopify checkout architecture evolves

Affirm's Shopify payment app has required merchant updates multiple times as Shopify changed its checkout infrastructure. Merchants who missed those updates lost access to Affirm at checkout. Shero's post-launch retainers include Affirm monitoring and update management alongside the rest of the store's payment stack.
