What you can change in Shopify checkout today

Shopify runs checkout on its own platform, separate from your theme. You customize it in the checkout and accounts editor and with apps built as extensions. Shopify Help lists two recent cutoffs. As of June 30, 2026, Shopify Scripts are deprecated and deactivated, with Shopify Functions as the replacement. August 26, 2026 was the deadline for non-Plus stores to upgrade their Thank you and Order status pages, and Shopify upgraded stores that missed it automatically.

What you can touch depends on your plan. This table follows the Shopify Help Center as of September 2026:

Customization	Basic, Shopify, Advanced	Shopify Plus
Branding and layout in the checkout editor	yes	yes
One-page (default) or three-page checkout	yes	yes
Apps on Thank you and Order status pages	yes	yes
Post-purchase extensions	yes	yes
Web pixels for tracking	yes	yes
Public apps built on Shopify Functions (discounts, delivery, payment rules)	yes	yes
Checkout customization per market	Advanced only	yes
Apps on information, shipping and payment steps	no	yes
Custom apps built on Shopify Functions	no	yes
Checkout Branding API	no	yes

On Plus you can add extensions inside the checkout steps, and our page for Shopify Plus agency work covers the enterprise plan in detail. On the other plans, your levers are the steps before checkout, the payment and shipping settings, and the pages after it. How checkout fits with Google Ads, feeds and email for your store is on our Shopify agency page.

Where orders drop, in numbers

Shopify's conversion funnel report shows sessions that added to cart, reached checkout and completed checkout. Take a store with 100,000 sessions a month, $80 average order value, 4% of sessions reaching checkout and half of those completing it:

Scenario	Reached checkout	Checkout completion	Orders	Monthly revenue	Extra per quarter
Today	4.0%	50%	2,000	$160,000	$0
Better checkout	4.0%	55%	2,200	$176,000	+$48,000
Better product pages and cart	4.4%	50%	2,200	$176,000	+$48,000
Both	4.4%	55%	2,420	$193,600	+$100,800

Orders = sessions × reached-checkout rate × checkout completion100,000 × 4.4% × 55% = 2,420 orders

Raising reached-checkout from 4.0% to 4.4% is worth exactly as much as raising checkout completion from 50% to 55%. On non-Plus plans you control the first number almost entirely through product pages, cart and bundles. Together, both levers add more than $100,000 a quarter in this example.

What our Shopify conversion work covers

Product pages

Price, delivery date and shipping cost above the fold, variants that are easy to pick on a phone, reviews where buyers hesitate.

Cart and bundles

Sets, quantity breaks and add-ons that raise order value without blocking the path to checkout.

Checkout settings

Guest checkout, express payment, one-page layout, fewer required fields, clear shipping options.

Checkout apps by plan

Upsells and trust blocks on the Thank you page for every plan, extensions in the checkout steps on Plus.

Tracking

Web pixels and customer events set up so Google Ads receives the right purchase values after the checkout upgrade.

After the order

Order status page and post-purchase offers. Repeat orders run through Shopify email marketing.

Baymard Institute found that the average US checkout shows 23.48 form elements by default, while an ideal checkout can be as short as 12 to 14. Every field you remove from Shopify's checkout settings shortens the path for every buyer.

Measure Shopify conversion without fooling yourself

Shopify changed how it counts sessions between September 21 and 23, 2026. Sessions now follow continued customer activity instead of ending at midnight UTC, sessions without a pageview count too (for example a shopper going straight to checkout from a cart link), and Shopify filters identified bots out by default.

Your conversion rate can move even though orders and sales stay the same. Compare periods only on the same side of that change, or compare orders and revenue instead. Before you judge your store against the average ecommerce conversion rate, check which session definition the benchmark uses.

We judge every change by revenue per session and orders in your Shopify backend, net of returns. That is also where we measure our 100k guarantee.

Who Shopify checkout optimization is for

You run Shopify or Shopify Plus and buy a large share of your traffic through Google Ads.
Many shoppers add to cart, few reach checkout, or many reach checkout and leave.
Your checkout upgrade broke tracking or removed upsells you relied on.
Your mobile conversion rate trails desktop by a wide margin.

How to spot a good Shopify CRO partner

It knows your plan. Advice built for Plus checkout extensions does nothing on Basic or Advanced.
It works before checkout. Product pages and cart decide how many shoppers reach checkout at all.
It protects tracking. After every checkout change, Google Ads still needs the correct purchase value.
It counts orders in Shopify. A higher conversion rate after the September 2026 session change proves nothing by itself.

Harucon works as a growth partner. After the intro call you get a fixed offer in writing. The guarantee starts at $3M annual revenue, and you can still book a call below that.

Shopify checkout optimization FAQ

What changed in Shopify checkout in 2026?

Shopify Scripts were deprecated and deactivated as of June 30, 2026, with Shopify Functions as the replacement. August 26, 2026 was the deadline for non-Plus stores to upgrade their Thank you and Order status pages.

Which checkout customizations need Shopify Plus?

Apps on the information, shipping and payment steps, custom apps built on Shopify Functions and the Checkout Branding API are Plus only. Market-specific checkout customization needs Advanced or Plus.

Should I use one-page or three-page checkout?

One-page checkout is Shopify's default and you can switch in your admin. Decide by orders and revenue per session over the same period.

Why did my Shopify conversion rate change without more orders?

Shopify changed session counting between September 21 and 23, 2026. Bot filtering lowers session counts and raises conversion rate, while counting sessions without pageviews lowers it.

What is a good checkout completion rate?

It depends on your traffic and products. Track sessions that completed checkout divided by sessions that reached checkout in the Shopify funnel report and compare it with your own prior periods.

What does Shopify checkout optimization with Harucon cost?

That depends on the size and starting point of your brand. After the intro call you get a fixed offer in writing, before anything starts.
