Amazon launches the Amazon Payments partner program to integrate “Pay with Amazon” option into e-commerce platforms like Shopify, not just individual merchants
Context & Ripple Effects
In 2016, Amazon began courting e-commerce platforms rather than just individual merchants, launching a partner program to embed Pay with Amazon checkout outside its own marketplace. The move set up a decade-long contest over who owns the checkout button on third-party storefronts.
Shopify answered by building out its own financial stack: partnering with Affirm for installment plans, launching merchant cash advances weeks after Amazon's program debuted via Shopify Capital, and later pushing Shop Pay beyond its own base. The contest finally converged in 2023, when Amazon brought the Buy with Prime app to Shopify and made Stripe its strategic payments partner.
First-order effects
- Merchants on integrated platforms can offer Amazon-account checkout without individual integration work, putting Amazon's login and stored payment credentials in front of shoppers far from amazon.com.
- Amazon gains distribution for its payments rail at the platform layer instead of signing up merchants one by one, shifting sales effort onto partners like Shopify.
Second-order effects
- Shopify's counterplay was to make its own wallet portable — extending Shop Pay to any US merchant on Facebook or Google whether or not they run Shopify — turning checkout into a land-grab where each side distributes the other's rival.
- Payment partners get pulled into the orbit of whichever platform wins shelf space, a dynamic visible when Shopify added Affirm for installments and Stripe aligned with Amazon across three regions.
Third-order effects
- Checkout is consolidating around a few platform-owned wallets rather than open card flows, forcing merchants to choose which identity graph — Amazon's or Shopify's — mediates their customer relationships.
- The end state visible in the coverage is co-opetition at the infrastructure level: rivals embed each other's payment programs while keeping proprietary alternatives, making payments partnerships a structural feature of e-commerce rather than a one-off deal.
The trend: E-commerce checkout is evolving from a per-merchant feature into a platform-level battleground where Amazon and Shopify each distribute their own wallet through third-party channels.
