Powering payments for leading ecommerce brands

Ecommerce moves fast. Primer keeps up.

Payments impact everything: conversion, margins, expansion, and customer experience. But most retailers still face complexity, blind spots, and blockers across the flow. That’s why forward-thinking retailers are using Primer to unify their payments stack, remove operational friction, and unlock performance across every transaction, from checkout to payout.

Make your payments stack as agile as your strategy

Expand into new markets, build resilience into your stack, and optimize costs by integrating with multiple processors through a single platform without extensive engineering efforts.

Test and optimize every payment flow

Experiment across your payment flow—from routing and authentication to retries—so you can double down on what works, drop what doesn’t, and convert more shoppers.

Build a checkout that fits every market

Reduce cart abandonment with a fast, localized checkout experience that you can tailor to reflect customer preferences in every market.

Stay secure without slowing down sales

Natively integrate with leading fraud prevention platforms and apply dynamic risk controls that keep conversions high and bad actors out.

Get full visibility into payment performance

Gain end-to-end visibility across the entire flow—from checkout to payout—to cut costs, align teams, and make smarter decisions that grow revenue.

Real outcomes.
Real impact.

With Primer, we’re in control of our payments, and we’re able to make changes fast without relying on engineering efforts.
