LatchPay vs CheckoutChamp for Shopify stores

LatchPay and CheckoutChamp both move buyers from the Shopify storefront to a checkout outside Shopify, and both send the paid order back to Shopify. CheckoutChamp is a broad platform, with funnel builder, CRM, split testing, subscriptions and hundreds of gateways, that you bolt onto Shopify and other store platforms using your own merchant accounts. LatchPay is narrower: it replaces only the checkout page and the card charge, takes the payment on your own Whop business, and leaves everything else in Shopify.

This comparison uses LatchPay's own documentation for LatchPay, and only checkoutchamp.com and CheckoutChamp's help center for CheckoutChamp. Facts about CheckoutChamp are as of September 2026 and linked where they appear. Where CheckoutChamp's pages say something different, theirs are the source to trust.

What each product is

LatchPay

LatchPay replaces the Shopify checkout page and the card charge. A buyer presses Checkout, a hosted LatchPay checkout opens, quotes the cart live from Shopify, takes the payment on the merchant's own Whop business, and LatchPay creates the paid order in Shopify. Whop is the merchant of record on that business, so card statements start with WHOP*. See What LatchPay does, and what it does not.

CheckoutChamp

CheckoutChamp describes itself as a custom checkout and one-click upsell platform that is designed to enhance your existing store, not replace it: you stay on Shopify, WooCommerce, BigCommerce or Magento and add the features you want. Its features page covers a drag-and-drop builder for stores, sales funnels and checkout pages, a CRM for many stores and SKUs, split testing, subscriptions and multi-currency selling. Payments run through gateways and merchant accounts you connect.

Pricing

LatchPay

From the fees page: Starter is €100 per 30 days plus 0.5% of paid orders minus refunds; Scale is €299 per 30 days plus 0.25%. The two cost the same at €79,600 of paid orders a month. The usage fee is billed weekly to the card on your LatchPay membership and never taken out of a payout. No setup fee.

On top: Whop's processing fee on each store payment, under Whop's terms, and Shopify's third-party transaction fee, which may apply because the payment runs outside Shopify Payments. See Whop's and Shopify's fees on top.

CheckoutChamp

CheckoutChamp's pricing page lists a single plan at $299 per month plus a 0.25% revenue share, with all tools included. The page's FAQ also mentions enterprise pricing that applies once an account processes more than the amount in its agreement, and a 60-day setup period with an account manager, after which continued account-manager support is an additional monthly charge. Your gateway's processing fees are separate, and Shopify's third-party transaction fee would be expected on payments outside Shopify Payments; confirm both for your setup.

What the numbers mean

At the top line, LatchPay's Scale plan and CheckoutChamp's plan have the same shape (a monthly fee plus 0.25%), though one is in euros and the other in dollars. LatchPay's Starter plan has a lower monthly fee and a higher rate, which suits stores below about €80,000 a month. The bigger cost difference is usually processing: with CheckoutChamp you negotiate rates with your own gateways; with LatchPay you pay Whop's published rates.

Features

Checkout and funnels

LatchPay's checkout editor edits the checkout and the thank-you page. The checkout stays a one-page checkout in the shape of Shopify's, and you add blocks: reviews, trust badges, payment logos, a guarantee, FAQ, a free-shipping bar, a reservation timer, a countdown discount, order notes, gift messages, custom fields, paid gift wrap and your own HTML and CSS.

CheckoutChamp goes further into funnels: a drag-and-drop builder for store pages, sales funnels and checkouts, with a CRM behind it that manages many stores and SKUs from one dashboard. If you build separate landing-page funnels, that is a real advantage.

Upsells

LatchPay has an order bump at checkout and a post-purchase offer on the thank-you page. The post-purchase offer can charge the saved card or wallet in one click when the buyer ticked a consent box, and becomes a second Shopify order that ships with the first. There is one offer per paid checkout.

CheckoutChamp's one-click upsells page says you can add as many upsells and downsells as you like, each bought with one click, and it offers 4-way split testing of checkout and upsell pages.

Payments

CheckoutChamp's payment options page says it is integrated with over 270 gateways, including NMI, Authorize.net, Stripe, PayPal, Checkout.com, WithReach and Aquired.com, and lists buy now, pay later integrations such as PayPal, Affirm, Afterpay, Klarna and Splitit. You need your own merchant accounts with those providers. We did not find Whop in the gateway names CheckoutChamp lists on that page.

LatchPay uses one processor per store: your own Whop business. Buyers see the methods Whop offers for the order, card first, and you can hide methods per store (Payment methods). You do not need to open a separate merchant account; you connect a Whop business.

Fraud, disputes and tracking

LatchPay's fraud rules score each checkout, hold risky orders for review or decline them before any charge. Disputes and pre-dispute alerts from Whop are linked to the Shopify order, and you can file evidence from LatchPay. Server-side tracking sends checkout events to Meta, TikTok, Google Analytics 4, Pinterest and Snapchat.

Setup

LatchPay

1. Create an account and choose a plan.
2. Connect Shopify through a custom app in your own Shopify organization.
3. Connect Whop and pick the business for store payments.
4. Add the theme line, place a test order, then switch the checkout on.

The setup overview lists every step. Switching off in Settings restores Shopify's checkout on the next page load.

CheckoutChamp

CheckoutChamp's Shopify help has you create a custom app in Shopify, add the Shopify plugin in CheckoutChamp and sync your products into CheckoutChamp. To send orders to Shopify, you add a Shopify plugin instance per campaign. For the storefront redirect, the redirect guide says to consult your account manager for Shopify. Onboarding runs with an account manager during the 60-day setup period.

What stays in Shopify

With LatchPay: products, variants, inventory, prices, discount codes, shipping rates, tax, Markets currencies, orders, fulfilment, confirmation emails and customers. LatchPay copies nothing out of Shopify; it quotes the cart live and writes the paid order back. See LatchPay and Shopify.

With CheckoutChamp, products are synced into CheckoutChamp and orders are sent back to Shopify per campaign, and CheckoutChamp's CRM keeps its own record of customers and orders. That is by design for a platform that runs funnels and subscriptions across several stores.

Honest limits of LatchPay

• Shop Pay and the storefront's express buttons are hidden while it is on; Apple Pay and Google Pay are offered on the checkout where Whop offers them.
• Checkout apps that inject into Shopify's own checkout do not run.
• One discount code per order, no subscriptions or selling plans, no split testing.
• It depends on replacing the checkout from the theme, which Shopify may restrict in future.

Which to choose

CheckoutChamp is built for brands that want a full funnel and subscription platform, run several stores or platforms, and have their own merchant accounts. LatchPay is built for Shopify merchants who want to keep Shopify as it is, replace only the checkout and charge, take payments on their own Whop business, and set it up themselves.
