300 Million Accounts at Your Checkout
Most ecommerce credit card processing solutions ask your customers to pull out a credit card, type in a 16-digit number, and trust a checkout page they've never seen before. Amazon Pay skips that entire sequence. By connecting your store's checkout to the payment and shipping information already saved in hundreds of millions of Amazon accounts, Amazon Pay turns a multi-step purchase into something closer to a single click. We score Amazon Pay 7.4 out of 10 for ecommerce credit card processing, with its strongest marks in buyer trust and checkout speed, and its most notable limitations in merchant-side flexibility.
The service works as an overlay on your existing checkout flow. Customers see the Amazon Pay button, log in with their Amazon credentials, and confirm a purchase using stored card and address details. They don't create a new account on your site, don't re-enter shipping information, and don't second-guess whether they're handing their card number to an unfamiliar merchant. For the customer, the experience feels like buying on Amazon.com. For you, it's a payment method that converts browsers into buyers by removing the friction that causes cart abandonment.
Amazon's Built-In Checkout Advantage
Amazon Pay launched in 2007 under the name "Pay with Amazon" before rebranding in 2017. It's operated by Amazon.com, Inc. (NASDAQ: AMZN), a company with a market capitalization that regularly places it among the three most valuable businesses on Earth. Amazon employs over 1.5 million people globally and reported more than $600 billion in net sales for fiscal year 2024. The payment service sits on top of that infrastructure, giving merchants access to over 300 million active customer accounts worldwide, including more than 200 million Prime members.
What makes Amazon Pay different from a traditional payment gateway is what happens on the buyer's side. Your customer clicks the Amazon Pay button, authenticates with their existing Amazon credentials, and confirms the purchase using a card and shipping address already on file. No new account creation. No manual entry of payment details. That reduction in steps directly targets one of ecommerce's most persistent problems: shoppers who start checkout but leave before completing their purchase.
Amazon's A-to-z Guarantee extends to purchases made through Amazon Pay on third-party sites, covering buyers if items don't arrive or don't match their description. That's a meaningful trust signal. Shoppers who hesitate on an unfamiliar merchant site often convert when they see the Amazon Pay option because the guarantee follows them off Amazon.com. Fraud protection is built into the service as well, with Amazon handling detection and risk management at no additional cost to the merchant. You don't need to bolt on a separate fraud screening tool or pay per-scan fees for transaction monitoring.
The service accepts Visa, Mastercard, Discover, American Express, Diners Club, and JCB credit cards, along with Visa and Mastercard debit cards. Customers can also use Amazon Gift Card balances for eligible purchases. Integration is available through major ecommerce platforms including Shopify, BigCommerce, WooCommerce, PrestaShop, and Adobe Commerce, with a direct API option for custom-built stores.
What Amazon Pay Costs for Ecommerce Merchants
There's no monthly fee, no setup cost, and no cancellation penalty. Amazon Pay uses a flat-rate, pay-as-you-go model. You pay only when a transaction processes successfully.
Domestic transactions cost 2.9% plus $0.30 per transaction. Cross-border transactions, where the buyer's billing address is in a different country than your merchant account, cost 3.9% plus $0.30. Amazon also charges a $0.30 authorization fee that's included in the total transaction fee when a payment processes successfully. If a successful authorization isn't captured and later closes or expires, you'll still pay that $0.30. Chargebacks cost $20 per dispute regardless of outcome, and that fee isn't refundable even if you win.
For a solo ecommerce merchant processing $10,000 per month with an average order value of $75, that's roughly 133 transactions monthly. At the domestic rate, each transaction costs about $2.48 in fees, putting your monthly total around $329 and your annual cost at $3,948. Compare that to a mid-size online store processing $50,000 monthly at the same average ticket: roughly 667 transactions, about $1,651 in monthly fees, and $19,812 per year. Those numbers assume all domestic transactions. If 15% of your volume comes from cross-border orders, the annual cost rises by approximately 8% to 10% because of the additional 1% processing fee on international transactions. Factor in chargebacks as well. At $20 per dispute, a store averaging just two chargebacks per month adds $480 to the annual processing bill, and that cost doesn't go away even when you win the dispute. The absence of monthly fees softens the overall cost structure, but the per-transaction math is identical to what most flat-rate processors charge, so the financial case for Amazon Pay depends on whether the conversion lift justifies adding it alongside your existing gateway.
Amazon Pay does offer volume-based rate reductions for high-volume merchants. The adjustments happen automatically based on your previous month's processing volume, which is more transparent than processors that require you to call a sales team and negotiate. However, the thresholds and reduced rates aren't published on Amazon's website, so merchants processing under six figures monthly shouldn't expect significant savings beyond the standard rate.
One detail that catches merchants off guard is the refund policy on fees. If you issue a refund, Amazon returns the percentage-based processing fee but keeps the $0.30 authorization fee. On a $50 refund, you've permanently lost $0.30. On a high-return product category, that adds up faster than most merchants anticipate.
Where Amazon Pay Fits Your Online Store
Amazon Pay works best when your customer base overlaps heavily with Amazon's. Consider a direct-to-consumer brand selling specialty kitchen equipment through its own Shopify store. The typical buyer is already an Amazon Prime member who shops online weekly. When that customer lands on your checkout page and sees the Amazon Pay button, they can complete the purchase in seconds using credentials they use almost daily. That familiarity isn't just convenience. It's a trust shortcut that reduces the mental friction of handing payment information to a smaller, less-known brand.
The conversion lift is real, though the numbers vary by merchant. Amazon reports that merchants using Amazon Pay see up to 35% higher checkout conversion rates compared to native merchant checkouts. Merchants selling in the $50 to $300 range, where cart abandonment peaks because buyers weigh the purchase more carefully, tend to see the most impact. The Affirm buy-now-pay-later integration, which activates automatically for cart totals above $50, adds another conversion lever for higher-ticket items.
International sellers also benefit. If you're a U.S.-based merchant with European or Japanese customers, those buyers can pay with the Amazon credentials they already use in their home market. The 3.9% cross-border rate is competitive with what most flat-rate processors charge for international transactions.
Amazon Pay doesn't make sense as your only payment method. It's an addition to your checkout, not a replacement for a full-service processor. A customer without an Amazon account can't use it, and not every Amazon customer will choose it. You'll still need a primary gateway for the majority of your card-present and card-not-present transactions.
What Amazon Pay Doesn't Cover
Amazon Pay is strictly online. There's no card reader, no terminal, no point-of-sale hardware. If you sell at trade shows, in a retail location, or anywhere that involves a physical card swipe or tap, Amazon Pay can't process those transactions. It handles ecommerce checkout and voice commerce through Alexa-enabled devices, and that's the boundary.
Phone orders and manual card entry aren't supported either. If your business takes orders over the phone or keys in card numbers for customers who call in, you'll need a separate processor for those transactions. The service is built entirely around the customer-initiated checkout button experience.
Recurring billing support exists through the Checkout v2 API, but the implementation is more limited than what dedicated subscription platforms offer. Merchants running complex subscription models with usage-based billing, mid-cycle plan changes, or prorated upgrades will likely find Amazon Pay's recurring tools too basic for their needs.
Reporting and analytics within Amazon Pay's Seller Central dashboard are functional but sparse. You can view transaction history, settlement reports, and dispute status. But if you're used to the granular breakdown that standalone payment dashboards provide, such as revenue trends by payment method, cohort analysis, or chargeback rate tracking over time, the Amazon Pay interface will feel limited. The navigation within Seller Central can also be disorienting, as the dashboard serves multiple Amazon services and the Amazon Pay section isn't always immediately intuitive to locate.
What's Changed with Amazon Pay Recently
Amazon Pay's most significant recent development is the Affirm integration, which adds buy-now-pay-later options directly through the Amazon Pay button on merchant sites. For eligible purchases above $50, customers can split payments into installments with no hidden fees. The integration requires Checkout v2, Amazon Pay's current API version, and activates automatically for merchants on supported platforms. Amazon reports that merchants offering Affirm see repeat purchase rates around 20%, and BNPL options can lift conversion rates by 20% to 30% on higher-ticket items.
The Checkout v2 migration deadline has been extended to March 31, 2026, giving merchants more time to upgrade from the legacy v1 integration. The v2 API handles payment method and delivery address selection on Amazon's side rather than through widgets embedded in the merchant checkout, which Amazon says improves security and reduces technical maintenance. Merchants using hosted ecommerce solutions like BigCommerce receive the upgrade automatically through their platform.
Amazon Pay also expanded its partnership with Stripe in April 2024, allowing merchants who already use Stripe as their primary processor to add Amazon Pay as a checkout option through Stripe's platform. That's a practical path for stores that want Amazon Pay's conversion benefits without managing a second merchant account relationship. And the Shopify Payments integration, which rolled out in early 2024, lets U.S. Shopify merchants activate Amazon Pay with a single click inside their Shopify admin, with all transactions managed and reported through Shopify's dashboard at no additional fee beyond standard Shopify Payments rates.
The Verdict on Amazon Pay
Amazon Pay solves a specific problem well: it lets ecommerce merchants borrow Amazon's trust and checkout speed to convert more visitors into buyers. If your customers are already Amazon shoppers, and statistically most American online buyers are, adding Amazon Pay to your checkout is one of the simpler ways to reduce cart abandonment without overhauling your site's purchase flow. The 2.9% plus $0.30 domestic rate won't save you money compared to other flat-rate processors, but the conversion lift can more than offset that cost if it turns even a small percentage of your abandoned carts into completed orders.
The limitations are structural. Amazon Pay can't serve as your primary processor because it only works online, only works for customers with Amazon accounts, and doesn't offer the full suite of tools that a standalone payment platform provides. The reserve policy for new merchants, which holds 100% of funds for seven days, creates a real cash flow constraint during your first months. And you're building a dependency on Amazon's ecosystem, which means your checkout option's future is tied to Amazon's product decisions, not yours. For merchants who accept that trade-off and treat Amazon Pay as a high-conversion supplement to their existing processing setup, it delivers clear value.
