1. Shopify Checkout Blocks

Best for: Every Shopify store that wants free blocks on the pages it is actually allowed to edit.

We reviewed Checkout Blocks first because Shopify makes it, and Shopify staff state plainly on its listing that the app is 100 percent free (Source: Checkout Blocks listing). The honest limit matters just as much: editing within the checkout flow requires Shopify Plus, while the Thank you and Order status pages can be customized across all Shopify plans, per Shopify replies on that same listing (Source: Checkout Blocks listing). Shopify help pages explain that blocks are added in the checkout editor and published inside a checkout configuration, with more than 20 block types covering upsells, custom fields, content, and address validation (Source: Shopify Help Center on checkout configurations).

Pros

• Free with no paid tier, so it adds nothing to your monthly app fees on any plan.
• Native to Shopify, so blocks are managed in the same checkout editor you already use for branding.
• Thank you and Order status blocks work on standard plans, which is where small stores can genuinely act today.

Cons

• Blocks inside the checkout flow require Shopify Plus, so a standard plan store cannot place upsells or fields before payment (Source: Checkout Blocks listing).
• On standard plans your canvas is two post purchase pages, which limits how much conversion work the app can do for you.
• A block only appears after you add it in the checkout editor and publish that configuration, so an install alone changes nothing (Source: Shopify Help Center on checkout configurations).

Pricing: Free, $0. No paid plan, checked 6 November 2026. Pricing page: https://apps.shopify.com/checkout-blocks

Skip it if: You are on a standard plan and your whole goal is editing the payment step itself. No app on this list can lawfully give you that on a standard plan.

Unique detail: Shopify developers answer listing questions directly and have confirmed there that the app is completely free and that editing within checkout needs Plus, while Thank you and Order status editing does not (Source: Checkout Blocks listing).

Fits: Stores of any size. For small stores on standard plans it covers post purchase pages free; for Plus stores doing hundreds to thousands of orders a month it covers the checkout itself.

Pick this if you want the free native baseline first. Everything else on this list should have to beat $0 and native.

2. Qikify Checkout Customizer

Best for: Shopify Plus stores that want upsells, custom fields, and payment method control in one app.

We compared Qikify because its own checkout page separates what every store gets from what Plus unlocks. The free plan works for all Shopify stores and covers customizing payment methods and delivery methods, such as hiding, renaming, or reordering them, while custom branding is a Plus only feature (Source: Qikify Checkout Plus). Premium, listed as Checkout Premium at $99 per month or $950.40 per year with a 14 day free trial, is built for Plus, Sandbox, and development stores and adds checkout upsells, custom fields, and validation rules (Source: Qikify Checkout Plus). The App Store listing carries the same $99 per month Premium price, checked 6 November 2026 (Source: Qikify Checkout Customizer listing).

Pros

• The free plan is useful on its own, since payment and delivery method cleanup fixes real checkout confusion at $0.
• Premium bundles upsells, fields, and validation in one app instead of three separate subscriptions.
• Premium includes free setup services and a dedicated account manager for Plus merchants, which shortens the path to a working checkout (Source: Qikify Checkout Plus).

Cons

• The advanced features most stores want, including upsells and custom fields, require Shopify Plus because Shopify restricts checkout editing to Plus (Source: Qikify Checkout Plus).
• Custom branding is Plus only as well, so standard plan stores cannot restyle checkout with this app.
• There is no mid priced tier. You jump from free straight to $99 per month, which is a real fee for a small Plus store.

Pricing: Free plan available. Premium $99/month or $950.40/year, 14 day free trial, checked 6 November 2026. Pricing page: https://qikify.com/pages/checkout-plus

Skip it if: You are not on Shopify Plus and need more than payment and delivery method tweaks, or $99 per month needs more upsell revenue than your order volume can produce.

Unique detail: Annual Premium billing is priced at exactly $950.40 per year on the vendor page, a 20 percent saving against paying monthly, and the page offers free setup as part of that plan (Source: Qikify Checkout Plus).

Fits: Plus stores from a few hundred orders a month upward, where one working upsell and cleaner payment options can cover the fee without strain.

Pick this if you are on Plus and want the fullest feature set with setup help included, rather than assembling blocks yourself.

3. Checkout Bear

Best for: Shopify Plus stores that would rather pay per checkout view than carry another flat monthly fee.

We checked Checkout Bear, by Conversion Bear, because its pricing model is unlike anything else here. Its App Store listing prices it as free to install, with the first 100 unique checkout impressions free and $0.06 charged per unique impression after that (Source: Checkout Bear listing). The listing positions its checkout editor for Plus stores and covers product upsells, free gift offers, trust badges, a countdown timer, a line item editor, and custom content blocks (Source: Checkout Bear listing). That mix targets the two levers small Plus stores care about: a higher AOV from one good offer, and fewer doubts at the payment step.

Pros

• No flat monthly fee, so a quiet month costs very little and the first 100 unique impressions are free (Source: Checkout Bear listing).
• Trust badges and countdown blocks sit beside upsells, so reassurance and revenue features live in one editor.
• The line item editor lets shoppers adjust what is already in the order, which can save a checkout that would otherwise be abandoned and restarted.

Cons

• Usage pricing follows traffic, not orders. A busy browsing week with weak conversion still generates impression charges (Source: Checkout Bear listing).
• At $0.06 per unique impression, a store with heavy checkout traffic can quietly pass the cost of a flat plan without noticing.
• The checkout editor is built for Plus stores, so standard plan stores cannot use it to edit the checkout flow.

Pricing: Free to install. First 100 unique checkout impressions free, then $0.06 per unique impression, checked 6 November 2026. Pricing page: https://apps.shopify.com/checkout-bear

Skip it if: Your checkout traffic is high and your conversion rate is low, because you would pay for views that never become orders.

Unique detail: Checkout Bear bills on unique checkout impressions rather than orders or revenue, so two stores with identical sales can pay very different amounts depending on how many shoppers reach checkout (Source: Checkout Bear listing).

Fits: Plus stores with modest, steady checkout traffic, roughly up to a few thousand checkout starts a month, where per impression pricing stays below flat plan prices.

Pick this if your traffic is small but valuable. Paying per view beats a flat fee until the day your impressions say otherwise.

4. Checkout Bricks

Best for: Shopify Plus stores that want every checkout feature for one small flat price.

We reviewed Checkout Bricks because its listing keeps pricing refreshingly simple. The listing describes a single Standard plan at $9.99 per month with all features included and unlimited order volume, built exclusively for Shopify Plus (Source: Checkout Bricks listing). The feature list runs wide for the price: upsells with AI product recommendations, custom fields for gift messages and delivery notes, warranty and gift wrap options, custom styling, age verification, and an address blocker for unsupported areas (Source: Checkout Bricks listing). The listing also states there is no revenue share, so a good upsell month does not raise your app bill (Source: Checkout Bricks listing).

Pros

• At $9.99 per month flat, it is the cheapest full feature checkout editor in this comparison.
• Unlimited order volume and no revenue share mean success does not trigger a bigger bill.
• Practical blocks like address blocking and age verification solve compliance and delivery problems, not just upsell space.

Cons

• It is designed exclusively for Shopify Plus, so standard plan stores cannot use it at all (Source: Checkout Bricks listing).
• There is no free plan, so the $9.99 starts as soon as the trial, if any is offered at install, ends.
• One single plan means no lighter tier. A store that only wants a gift message field pays for the whole toolbox.

Pricing: Standard $9.99/month, all features, checked 6 November 2026. Pricing page: https://apps.shopify.com/checkout-extensify

Skip it if: You are not on Shopify Plus, full stop, or you want a free tier to learn on before paying anything.

Unique detail: The listing pairs its flat price with an explicit no revenue share promise and unlimited order volume, which is the opposite pricing philosophy from per impression and percent of sales rivals (Source: Checkout Bricks listing).

Fits: Plus stores of any order volume that want checkout blocks without watching a usage meter, from a few hundred orders a month to very busy stores.

Pick this if you are on Plus and hate variable app bills. One small flat fee for the whole toolbox is an easy budget line.

5. Checkout Champ

Best for: High volume brands that have outgrown Shopify checkout and want a full replacement platform.

We included Checkout Champ as the honest outlier, because it is not a checkout extension at all. Its own pricing page sells a checkout and funnel platform, with the Growth plan at $300 per month plus 1 percent of sales (Source: Checkout Champ pricing). The pricing page FAQ says there are no charges for additional funnels, subdomains, or users, which suits brands running many campaigns at once (Source: Checkout Champ pricing). Treat it as a migration candidate for stores whose volume makes a percent of sales a rational trade, not as an app a small store installs on a Tuesday.

Pros

• One platform covers checkout and funnels, so campaign pages and payment pages stop living in separate tools.
• No per funnel, per subdomain, or per user charges, which keeps multi campaign testing predictable (Source: Checkout Champ pricing).
• Built for volume sellers, so the feature depth goes far beyond blocks, including funnel flows a standard checkout cannot run.

Cons

• $300 per month plus 1 percent of sales is the heaviest cost in this comparison by a wide margin (Source: Checkout Champ pricing).
• It replaces Shopify checkout rather than extending it, so adopting it is a migration project with real setup and testing work.
• The pricing page FAQ notes some tools, such as 3D Secure and fraud plugins, are separate billable items on top of the plan (Source: Checkout Champ pricing).

Pricing: Growth $300/month plus 1% of sales, checked 6 November 2026. Pricing page: https://checkoutchamp.com/pricing

Skip it if: You are a small store, you are happy with Shopify checkout, or a percent of sales would cost more than every other app in your stack combined.

Unique detail: The vendor pricing FAQ confirms extra funnels, subdomains, and users carry no extra charge, while named add on plugins do, so the real fine print sits in the plugin list, not the plan price (Source: Checkout Champ pricing).

Fits: Large brands with high monthly sales volume and dedicated funnel campaigns, well beyond small store order counts, where checkout control is a core revenue lever.

Pick this if checkout is your business model, not a page in it. For everyone else, it is a useful benchmark of what the deep end costs.
