Shop Pay Installments' 24-Month Terms Have a 6-Month Catch
Shop Pay Installments advertises 24-month terms and strong lift numbers. Here's exactly what Shopify's own eligibility gate and footnotes say.
Shop Pay Installments is Shopify's native buy-now-pay-later option, and Shopify's own marketing leads with strong numbers: a 50% increase in average order value for one in four merchants, 30% faster checkout for shoppers who've used installments before, and 28% fewer abandoned carts for merchants switching from a third-party BNPL provider. Those figures are real, but each is explicitly scoped to a subgroup, not presented as a guaranteed average — worth keeping in mind before building a rollout plan around the headline number.
The Eligibility Gate Is Binary
Before any of those numbers matter, a merchant has to clear a hard gate. Per Shopify's own eligibility language, a store must be based in the United States, sell in USD, and have both Shopify Payments and Shop Pay activated. There's no stated path for a non-US or non-USD store. Offering installments in-store through POS adds further requirements on top: Shopify POS app version 8.4.0 or later, and staff members need the "Create and edit" permission in the Draft orders section of their store permissions.
Standard vs. Premium: Different Order Ranges, Different Access
Shop Pay Installments comes in two packages. Standard covers purchases from $50 to $1,000: customers get 2 or 4 interest-free biweekly payments, or monthly installments up to 12 months. Premium covers a much wider range — $35 to $30,000 — and advertises monthly installments up to 24 months. But Premium isn't automatic: Shopify's page describes it as "available to eligible merchants" only, with eligibility checked by logging in, not guaranteed by simply qualifying for Standard.
The Footnote Behind "Up to 24 Months"
The Premium package's headline 24-month figure carries its own footnote, quoted directly from Shopify: "Some merchants may only be eligible to offer customers up to 6 months of interest-free monthly installments." Shopify doesn't publish the criteria that decide which merchants get the full 24 months versus the 6-month cap — the page states the cap exists without explaining what triggers it. Any rollout plan built around offering 24-month terms should confirm the actual terms a specific account is eligible for, in the admin, before promising that number to customers.
Reading the Lift Numbers Correctly
The same care applies to the lift figures. "50% increase in AOV" is scoped to one in four merchants, not the median outcome. "30% faster checkout" applies to shoppers who've already paid with installments before, not first-time buyers. "28% fewer abandoned carts" applies specifically to merchants who switched from a third-party installments solution. None of these are reasons to skip Shop Pay Installments — they're reasons to read Shopify's own fine print before setting expectations for a specific store.
