Short answer. If you run Salesforce Commerce Cloud, Adobe Commerce, BigCommerce, WooCommerce or a custom stack, you have four main ways to give returning shoppers Shop Pay-style one-click checkout without replatforming: Shop Pay itself (through Shopify's Shop Pay Wallet API), Fastlane by PayPal, Link by Stripe, and Bolt. The real difference is what each one ties you to. Shop Pay runs its payments on Shopify Payments and creates its orders in a separate Shopify store. Fastlane needs PayPal or Braintree to process your card payments. Link is built into Stripe. Bolt works with Bolt Payments or your existing processor, including Stripe, and keeps orders in your own system.
Why execs off Shopify ask this question
Shop Pay set the expectation: a returning shopper types an email, confirms a code, and pays without re-entering an address or card. Brands that run on other platforms see that and ask whether they can get the same result without a replatforming project.
The answer is yes, and Shopify itself now offers Shop Pay to brands that aren't on Shopify. So the question is no longer "can we have one-click?" but "which one-click, and what does it cost us in processors, systems and engineering?" That's what this guide compares.
The four options at a glance
Shop Pay on any platform. Shopify says you can add Shop Pay "without migrating to Shopify," and that it connects your store to over 250 million customers in the Shop Pay network [S1]. Shopify pitches the enterprise version as a Commerce Component for teams on "Salesforce, SAP, Magento, or a fully customized solution" [S3].
Fastlane by PayPal. A guest checkout accelerator. A shopper enters an email, confirms a one-time code, and gets saved card and address details. Fastlane profiles are separate from PayPal accounts and work across merchants that use Fastlane [F1][F2].
Link by Stripe. A Stripe wallet that autofills saved payment details after a one-time code. Stripe says Link reaches over 300 million consumers worldwide and is built into Stripe payments surfaces [L1].
Bolt. A one-click checkout with a shared shopper network of 100M+ US shoppers. It runs on your existing platform and works with Bolt Payments or your existing processor. Stripe is supported as a payment processor, and PayPal is offered as an alternative payment method within Bolt Hosted Checkout. Bolt has setup guides for Salesforce Commerce Cloud, Adobe Commerce, BigCommerce, WooCommerce and Shopify (through Bolt's hosted checkout), and custom stacks can use Embeddable Checkout (v3 API).
Comparison table
How we compared. Six criteria, chosen because they decide the cost of adding one-click off Shopify: (1) whether it works without moving to Shopify, (2) who processes the payment, (3) where orders and refunds live, (4) the shopper network each company reports, (5) fraud chargeback cover, and (6) the integration work its docs describe. Columns are in alphabetical order, not a ranking. Network sizes are each company's own figures and aren't measured the same way. Competitor cells cite a source ID; sources and read dates are at the end.
| Criterion | Bolt | Fastlane by PayPal | Link by Stripe | Shop Pay (Wallet API) |
|---|---|---|---|---|
| Works without moving to Shopify | Yes. Guides for SFCC, Adobe Commerce, BigCommerce, WooCommerce; Embeddable Checkout for custom stacks. Also runs on Shopify, through Bolt's hosted checkout | Yes. Added to your own checkout through PayPal's JS SDK or Braintree [F1][F2] | Yes. Included in Stripe Checkout and Payment Links; Payment Element for custom checkouts [L1] | Yes, through the Shop Pay Wallet API [S1][S2] |
| Who processes the payment | Bolt Payments or your existing processor; Stripe supported; PayPal offered as an alternative payment method within Bolt Hosted Checkout | PayPal or Braintree: "You must process card payments through Braintree to use Fastlane" [F1]; same rule with PayPal [F2] | Stripe. Link credentials "can't be transferred between payment processors" [L2] | Shopify Payments. Your business must be eligible for it [S1][S2] |
| Where orders and refunds live | Your platform and order management | Your system, through PayPal's Orders API [F2] | Your Stripe integration [L1] | Shopify creates the Shop Pay order in a new Shopify store you set up; you reconcile it into your system [S2] |
| Shopper network (company-reported) | 100M+ US shoppers | Not stated as a number on the pages we read | "Over 300 million consumers worldwide" [L1] | "Over 250 million customers" [S1] |
| Fraud chargeback cover | Total Fraud Protection: Bolt covers 100% of fraud chargebacks on approved orders (qualifying transactions, under your Bolt agreement) | Not addressed on the Fastlane pages we read | Not addressed on the Link page we read | Not addressed on the two Shopify pages we read |
| Integration work in the docs | Typically between a few days and a few weeks | PayPal JS SDK and Orders v2, PayPal shown next to the email field, billing address required [F2] | Automatic in Stripe Checkout; Payment Element otherwise [L1] | New Shopify store, Shopify Payments sign-up, Storefront and GraphQL Admin APIs, front-end and back-end work, order reconciliation [S1][S2] |
What each option ties you to
Shop Pay: a second payment and order stack
Shopify's docs are clear about the setup. You can't use the Shop Pay Wallet API on an existing Shopify store; you create a new one for the integration [S2]. You sign up for Shopify Payments, connect a bank account, and Shopify says payout details must be complete within 21 days of your first Shop Pay payment or those payments are refunded [S1]. Shopify processes the payment with Shopify Payments and is the source of truth for Shop Pay payment and order records. Your system keeps cart, discounts, shipping, taxes and inventory, and reconciles each Shopify order [S2].
That's a real trade. You get Shopify's network and brand recognition, and for the enterprise version Shopify says it provides program management and technical consultation [S3]. In return, Shop Pay orders run through a processor and an order system that sit next to the ones you already have. Shopify also says your team needs API integration experience, or a Shopify Partner to help [S1].
Fastlane: PayPal or Braintree processing
Fastlane is aimed at guest checkout. Its requirements are short and firm: card payments must run through PayPal or Braintree, PayPal must appear as a payment option near the Fastlane email field, and you must collect a billing address [F1][F2]. If PayPal or Braintree is already your card processor, Fastlane is a natural add. If it isn't, adding Fastlane means moving card processing.
Link: built for Stripe merchants
Link is on by default in Stripe Checkout and Payment Links and has no added charge for Stripe users [L1]. It doesn't travel to other processors: Stripe says credentials saved through Link are excluded from its forwarding product and that Link card transactions should go to Stripe [L2]. If Stripe is your processor, Link is close to free to turn on. If you process elsewhere, it means moving to Stripe.
Bolt: one-click on the stack you already run
Bolt is built for the case where you don't want to change platform or processor. It runs on Bolt Payments or your existing processor (Stripe included), keeps orders in your system, and recognizes shoppers from its network of 100M+ US shoppers. A recognized shopper confirms with their email and a one-time code; a new shopper can create a Bolt account in the same flow. Either way, the store keeps the shopper's name, email and other information as its own customer. Bolt account holders convert 50% better than guest shoppers, based on Bolt internal tests and data. Total Fraud Protection works with Bolt Payments and approved third-party processors, and covers 100% of fraud chargebacks on approved orders (qualifying transactions, under your Bolt agreement). Bolt says implementation typically takes between a few days and a few weeks.
Results we've published: REVOLVE saw a 10% lift in checkout conversion and 4% higher revenue, and FWRD saw a 9.92% conversion lift in a mobile A/B test (Nov to Dec 2023).
Bolt also offers a 10-20% conversion rate lift guarantee. How it works: if you don't get the results you like, you can terminate at any time and get out of any lock-in contracts. It isn't a money-back guarantee.
How to choose
Start from your processor, not the button.
- You're on PayPal or Braintree for cards and want to speed up guests: Fastlane fits with the least change [F1][F2].
- You're on Stripe: Link is already in Stripe Checkout and close to free to try [L1].
- You want Shop Pay's own network and can run Shopify Payments and a separate Shopify store next to your stack: Shop Pay through the Wallet API, with Shopify's enterprise team for help [S1][S2][S3].
- You want to keep your platform and your processor, keep orders in your own system, and add fraud chargeback cover from the same vendor: Bolt.
These aren't exclusive. Bolt can run as the one-click checkout on your email field while Shop Pay, PayPal or other express buttons stay on the page. Every vendor here, Bolt included, publishes its own conversion figures, so test against your current checkout on your own traffic before you commit.
