How to Show Shipping-Method-Wise ETA Messages on Shopify Plus Checkout

A customer lands on your store. Finds the perfect product. Adds it to the cart. Reaches checkout, and then they see it:

“Standard Shipping – $5.99” “Express Shipping – $14.99”

No delivery dates. No estimated arrival. Just names and prices.

They need the item by Friday. They have no idea if Standard will make it. So they leave.

Every day, shoppers abandon purchases when they can’t tell when an order will arrive. According to Narvar’s 2025 State of Post-Purchase Report, 73% of consumers say estimated delivery dates influence their purchase decisions, and 40% won’t complete a purchase if no delivery date is shown. Meanwhile, Baymard Institute’s checkout UX research found that 48% of eCommerce sites still fail to show delivery dates, relying instead on shipping speeds that force shoppers to calculate arrival times themselves. 

That gap costs real money. If you’re on Shopify Plus, you can make it go away by showing shipping-method-specific ETA messages directly at the checkout so that each option shows a clear estimated date of arrival.

Yes, that one is all about the importance of it, the process of preparing it, and so on.

Key Takeaways

• According to Narvar’s 2025 research, 73% of shoppers say that seeing an estimated delivery date influences their purchase decision, while 40% will not complete a purchase without one. This makes displaying delivery ETAs at checkout a conversion-driving necessity rather than an optional feature.
• Shipping-method-wise ETA messages remove delivery uncertainty at the exact moment it matters most: when the customer is choosing a shipping option.
• Checkout ETA transparency also reduces post-purchase WISMO support tickets and naturally drives upsells to faster shipping options.
• Shopify Plus is required; the Checkout Editor and Checkout Extensibility are not available on standard Shopify plans.
• The app-based setup via the Estimated Delivery Date & Time app is faster, more maintainable, and supports more ETA scenarios than a custom code solution.
• Method-level ETA rules can be layered with product-level, country-level, and ZIP code-level delivery configurations for a fully rounded delivery messaging strategy.

Why Customers Abandon Checkout Over Shipping Uncertainty

As of 2025, the global average shopping cart abandonment rate is 70.19%, meaning roughly 7 out of 10 online shoppers leave without completing their purchase. Research from Baymard Institute has consistently tracked cart abandonment rates around this level for several years. Additionally, delivery expectations play a major role in purchase decisions. Industry studies show that 19% of shoppers abandon their cart because delivery is too slow, while unclear or uncertain delivery timelines can significantly reduce conversion rates. Displaying accurate estimated delivery dates helps reduce uncertainty and improves checkout completion rates.

Delivery speed fell from the #1 consumer priority in 2022 to #5 in 2024. Consumers ranked on-time delivery and reliability higher than fast delivery, and many said they would rather wait up to a week for an order that arrives when promised than receive a late delivery. 

“Ships in 5–7 business days” is not a certainty. It’s a math problem at exactly the moment you want people to click Buy. A specific date is.

Real Merchants, Real Pain Points

For all you store types, here is where ship uncertainty falls.

Scenario 1: The Home Decor Brand

An online home decor seller presents various shipping choices, but no estimated delivery times; shoppers usually pick up the most affordable options and then call customer support. By displaying time-to-arrival messages for different shipping choices, shoppers can make educated decisions, sales upgrade rate for faster shipping increases, and customer support calls drop accordingly.

Scenario 2: The Gifting and Occasion Store

It’s also time-sensitive for gifting stores: Users buying gifts for birthdays, anniversaries, or holidays frequently start checkout, then bail when they can’t tell if something will arrive on time. Displaying delivery dates for different options reassures them, boosting conversions during peak seasons.

Scenario 3: The Apparel Brand Running Weekend Sales

Fashion stores with flash sales frequently have a high rate of WISMO calls. Providing Estimated Arrival Dates per shipping type minimizes confusion by providing parameters before an order is even placed.

Those are exactly the friction points the shipping-method-wise ETA messages on Shopify Plus checkout are meant to address.

What Are Shipping-Method-Wise ETA Messages?

Shipping-method-wise ETA messages are the different estimated arrival dates or windows under each shipping method on checkout. It is different from a simple display of method name and price; before the customer’s decision can be made, the customer will see the actual ETA of each for choosing.

Rather than:

• Standard Shipping: Free
• Express Shipping: $9.99

Customers see:

• Standard Shipping: Free  |  Estimated Delivery: Jul 24–26
• Express Shipping: $9.99  |  Estimated Delivery: Jul 22

One modification this makes, explicitly providing date context for each shipping option, eliminates the single most uncertain factor at the most crucial point in the entire purchase funnel.

How to Show Shipping-Method-Wise ETA Messages on Shopify Plus Checkout

Here are two ways to set this up. The app-based route is recommended for most merchants.

Option 1: Shopify App-Based Solution (Easy & Recommended)

The easiest way to show shipping-method-wise ETA messages on Shopify Plus checkout is with the Estimated Delivery Date app, with no-code setup, method-specific ETA rules, and flexible display options. 

Follow these steps:

Open Theme Customizer:  From your Shopify admin, go to Online Store → Themes, then click Customize on your active theme.

Add the ETA Widget to Checkout:  Navigate to Shopify Admin → Checkout Customization → open the Checkout Editor → go to the Shipping Method section → click Add Block → select Delivery Date – ETA → position the widget → click Save.

Create and Configure Shipping Methods:  Inside the app, click Create Shipping Method. A pop-up opens. Choose a display style: Visual Options or Classic Dropdown. Add your methods by typing and clicking Add, or use Sync from Shopify to import existing methods. Select the methods to display (Standard, Express, Free Shipping, etc.) → click Apply → then link each method to its ETA rule using the dropdown.

Save and Test on Your Storefront:  Save your settings. Open your live store, add a product to cart, proceed to checkout, and enter a shipping address. Confirm the ETA appears under each shipping method option. Once verified, the widget is live.

View ETA in Checkout Page:

Once configured, customers can instantly see delivery estimates for each shipping option, helping them choose with confidence while reducing checkout hesitation, support requests, and delivery-related uncertainty. 

Option 2: Custom Shopify Code Solution

Shopify Plus checkout customization through code is possible via Checkout UI Extensions using the @shopify/ui-extensions package. Build a custom extension that will read shipping rates and apply additional logic or calculations, then display a text block below each option.

However, this route has significant limitations that merchants should weigh carefully:

• Requires an experienced developer familiar with Shopify Checkout Extensibility
• ETA logic must be hard-coded; any change to carriers, cutoff times, or holiday exclusions requires a developer update
• Does not support dynamic ZIP/postcode-based delivery logic or holiday calendars out of the box.
• Testing, deploying, and maintaining the extension adds ongoing overhead
• For most stores, the custom code route costs 5–10x more over time compared to an app-based setup

Only consider this code path if your ETA needs are extremely specialized, and your developers are already within your checkout extension flow. For nearly all Shopify Plus merchants, the app-based approach is faster to implement, easier to maintain, and more capable of handling a wide variety of real-world ETAs automatically.

Conclusion

Delivering shipping-method-specific ETA messages in your Shopify Plus checkout is a quick, easy win for clarifying delivery timelines and enabling customers to buy with confidence. Customers only have to look at the estimated delivery dates for each shipping method in order to make much quicker, more confident decisions. From a custom build to the use of an app, converting your checkout to ETA transparency is sure to enhance sales, cut down on questions, and smooth out the shopping experience.
