Incumbents Protect Checkout Control
Jordan Gal, CEO of Rally, on building the Switzerland of checkout
The friction comes from the fact that checkout is where ecommerce platforms keep their grip on the merchant. Once a brand unbundles the storefront and starts mixing tools like Next.js, NetSuite, Klaviyo, and a separate fulfillment stack, the remaining point of control is usually payments and checkout. That gives incumbents a strong reason to keep checkout tightly integrated, because the checkout is where shopper identity, payment routing, and merchant lock in all converge.

Shopify’s model shows why incumbents resist a fully composable stack. Shop Pay is bundled with Shopify Payments, shoppers can reuse saved info across Shopify checkouts, and Shopify has pushed merchants toward standardized checkout extensibility instead of fully open checkout control. That keeps the highest leverage part of commerce inside Shopify’s system.

The economic prize is a third shopper network outside Amazon and Shopify. Jordan Gal frames Rally, Bolt, and Fast as trying to build that network by recognizing shoppers across merchants. Fast struggled because an extra wallet button captured too little payment volume per merchant, while Rally and Bolt moved toward full page checkout products that own more of the flow.

This is also why checkout products look more political than other ecommerce tools. A merchant can swap email, search, or analytics vendors without threatening the platform core. Swapping checkout changes who owns saved credentials, who chooses payment methods, who can run post purchase upsells, and who collects the data that powers repeat buying.
The next phase of commerce infrastructure is likely to center on independent checkout becoming the default layer for brands that outgrow all in one platforms. If that happens, the winners will be the products that let merchants keep their storefront freedom while still matching the speed and familiarity of Shop Pay or Amazon, without forcing the merchant back into a closed system.
