How much does Shop Pay increase conversions?

Shop Pay is Shopify's accelerated checkout. It saves the customer's shipping, billing, and payment info once at any participating store, then offers one-tap purchase at every other Shopify-powered store the same shopper visits later. Network effect: the longer Shop Pay has been live, the more shoppers already have credentials, the bigger the lift.

The headline 18% comes from Shopify's 2022 commerce trends report, which studied stores that enabled Shop Pay versus stores that did not, controlled for traffic mix and AOV. The lift is bigger on mobile (where typing card numbers is painful) than on desktop. Stores with traffic predominantly from younger, mobile-first shoppers see the highest end of the range; B2B-leaning stores selling to office desktops see the smallest lift.

The lift is not free. Shop Pay charges Shopify's standard payment-processing rates (2.4-2.9% + 30¢ depending on plan), the same as the base Shopify Payments integration. There is no extra per-transaction fee for Shop Pay specifically. If you are already on Shopify Payments, enabling Shop Pay is a settings toggle, not a cost decision.

Beyond the conversion lift, Shop Pay also drives a small but real AOV bump (~5%) because Shop Pay Installments (the buy-now-pay-later option) is included by default. Customers split orders into 4 interest-free payments, which lifts AOV without lifting cart abandonment. If Installments is not relevant to your category (low-AOV impulse buys), you can disable Installments separately while keeping the core Shop Pay checkout.

One catch: Shop Pay only works in the Shopify-controlled checkout. If you have customised the checkout via checkout extensions or a third-party headless setup, validate the Shop Pay integration end-to-end on mobile before you assume the 18% lift will land.
