Shopify Tools and Apps That Turn Checkout Friction Into More Sales
Tools and Apps That Turn Strategy Into Results
After our last checkout article, "Shopify Ecommerce Checkout Optimization: 6 Strategies to Increase Conversions and AOV for your Shopify Store", we received several requests from brand owners asking how those strategies could actually be applied inside Shopify.
So we created this guide to focus on the tools, apps, and setup steps that turn checkout optimization into something practical and easier to implement.
A strong Shopify checkout starts with understanding where customers drop off, what creates friction, and which tools can improve the buying experience without making it heavier.
That is where many store owners go wrong. They keep adding checkout tools before they understand what is actually causing friction. More features do not always create a better checkout. Sometimes, they only make the buying experience harder to complete.
Here are five practical Shopify checkout strategies that can help improve conversion rate and increase checkout value, along with the types of apps and tools that can support each one.
1. Set Up GTM and Shopify Customer Events Properly Before Making Checkout Changes
Before changing the checkout, store owners need clean tracking.
Without clean tracking, it becomes hard to know whether a checkout change is actually helping or just adding another layer to the buying journey. Store owners need to see where customers drop off, which steps create friction, and which changes actually move people closer to purchase.
That is why tracking should come first.
Shopify now supports tracking via Customer Events and custom pixels, which can send customer behavior data to Google Tag Manager and GA4. This gives store owners a cleaner way to track important actions without relying on old theme scripts or scattered code across the store.
The key events to track include:
Product views
Add to cart
Checkout started
Shipping details added
Payment details added
Purchase completed
Once these events are set up properly, they can be connected to GA4, Google Ads, Meta, or other analytics platforms to give store owners a clearer view of the full buying journey.
Apps and tools to consider: include Shopify Customer Events and custom pixels, the Google & YouTube app, Analyzify, and Elevar. These can help with GA4 setup, Google Ads tracking, server-side tracking, GTM data layers, and compatibility with Shopify’s newer checkout setup.
This helps store owners make checkout decisions based on real customer behavior. Instead of adding changes and hoping they work, you can see what is helping customers move forward, what is creating friction, and what is actually leading to completed purchases.
2. Replace Old Scripts With Shopify Checkout Extensibility and App Blocks
Many Shopify stores still have old scripts, tracking snippets, and checkout customizations that were added over time.
At first, this may not seem like a problem. But as the store grows, those pieces of code become harder to manage. A script that was added for tracking, an upsell, a trust message, or a thank you page edit can slowly turn checkout into something difficult to test, update, or troubleshoot.
This matters more now that Shopify is moving toward Checkout Extensibility. Instead of relying on old scripts or random code across the store, merchants can use supported checkout tools that are built to work inside Shopify’s current checkout system.
The best tools to use here are:
Checkout Blocks: Best for no-code checkout customization. It can be used for custom fields, banners, payment and delivery method rules, order value limits, and advanced discount logic. Shopify describes Checkout Blocks as a way to customize checkout without code.
Checkout UI Extensions: Best for adding custom checkout functionality in a more stable, Shopify-supported way. These extensions allow apps to add features inside defined areas of checkout, including product information, shipping, payment, order summary, and Shop Pay.
Custom Pixels: Best for replacing old tracking snippets. They help collect customer events across checkout and post-purchase pages without modifying theme code.
Web Pixels API: Best for more advanced tracking setups across cart, checkout, and purchase behavior. It gives developers access to Shopify’s standard customer events in a cleaner tracking structure.
Start by checking what is currently tied to checkout. Look through any tracking codes, upsells, surveys, thank you page edits, order status messages, payment rules, delivery rules, or custom logic. From there, decide what still has a clear purpose, what can be removed, and what should be rebuilt using Shopify’s supported checkout tools.
This makes checkout easier to control. Instead of stacking fragile scripts that may conflict with each other, store owners can build a setup that is cleaner, easier to test, and more reliable as Shopify continues updating its checkout system.
3. Use Apps to Reduce Shipping and Payment Friction
Shipping and payment issues can make customers hesitate right before they complete an order.
If shipping costs are unclear, delivery dates are missing, local delivery rules feel confusing, or payment options are not shown in the right way, the customer may pause.
A good setup should help customers understand when their order will arrive, what delivery options are available, and which payment methods apply to them.
Store owners can use delivery apps to show estimated delivery dates, processing times, shipping timelines, and delivery timers.
For stores with more complex delivery needs, shipping rule apps can help manage postcode-based rates, cart value rules, local delivery, delivery dates, and time slots. For payment friction, Shopify payment customizations can help hide, rename, or reorder payment methods so customers see the most relevant options first.
Tools to consider:
Essential Estimated Delivery Date: Best for showing processing time, shipping time, delivery timers, and estimated delivery dates on product pages. It helps set clearer delivery expectations before the customer reaches checkout.
ShipZip: Best for stores with more complex shipping and delivery rules. It can manage shipping rules by postcode, product, customer tag, cart value, weight, quantity, distance, delivery date, time slot, local delivery, and store pickup.
Shopify payment customizations: Best for organizing payment methods inside checkout. Shopify’s payment customization tools can rename, reorder, or hide payment methods based on business rules, which helps keep checkout cleaner and more relevant to the customer.
4. Add Relevant Post-Purchase Offers to Increase Checkout Value
When a customer is already checking out, you do not want to slow them down with too many extra offers. At that point, they are focused on finishing the order. If you show too many upsells before they pay, it can make them stop and rethink the purchase.
The cleaner approach is to let the customer finish the order first, then show one simple add-on right after purchase. This keeps the main checkout clean while still giving the store a chance to increase order value.
For example, a customer buying leggings could be offered matching socks, a sports bra, or a laundry care bag. The offer should be easy to understand, easy to accept, and closely connected to the original order.
This gives the store a chance to increase order value without interrupting the original purchase. The offer should feel like a natural next step, not a random product added at the last second.
Apps and tools you can use:
AfterSell: Best for one-click post-purchase upsells, thank you page offers, checkout upsells, and Smart Funnel AI. It works well for stores that want to build simple upsell funnels after the first purchase is already secured, without making the main checkout feel crowded.
ReConvert: Best for post-purchase funnels, upsells, cross-sells, thank you page customization, and analytics. This is useful when a store wants more control over the post-purchase experience and wants to track how each offer performs.
Shopify post-purchase checkout extensions: Best for custom post-purchase offers built directly into Shopify’s checkout flow. Shopify’s developer documentation explains that a post-purchase offer can let buyers add products to their order after payment is completed. This is the more flexible route for stores that want a custom-built experience instead of using a ready-made upsell app.
This improves checkout value because the first order is already complete. The customer can consider a useful add-on without feeling like the original purchase is being delayed.
5. Use Accelerated Checkout and Payment Flexibility to Improve Completion Rate
Payment flexibility matters most when the customer is already close to buying.
Some customers simply want the fastest way to pay, while others prefer using a payment method they already know and trust. For higher-ticket products, installment options can make the purchase feel more manageable, while accelerated checkout can help mobile shoppers finish faster by reducing the amount of typing required.
The goal is not to show every possible payment option. The goal is to give customers the right options for their market, device, and order value, then keep the checkout clean.
Shopify describes accelerated checkout as a way to save customer payment and shipping information so returning customers can complete payment faster. Shopify also positions Shop Pay as its best-converting accelerated checkout, claiming it converts up to 50% better than guest checkout.
Tools and payment options to consider:
Shop Pay: Best for fast checkout on Shopify. It stores customer details so that returning shoppers can complete orders faster, which is especially useful on mobile devices.
Shopify Payments: Best as the main payment setup for Shopify stores. Shopify says it is the simplest way to accept payments online and automatically sets stores up to accept major payment methods.
Shop Pay Installments: Best for higher-ticket products where customers may want to pay over time. Shopify says Shop Pay Installments can give customers more flexible payment options and can improve conversion rate and average order value.
PayPal Express Checkout: Best for customers who prefer paying through PayPal, bank accounts, buyer credit, or PayPal balances. Shopify also describes it as an accelerated checkout payment solution.
Apple Pay: Best for mobile and Apple device users who want a fast wallet-based checkout. Shopify supports Apple Pay through Shopify Payments or supported third-party providers.
Google Pay: Best for Android and Google Wallet users. Shopify says merchants can use Shopify Payments with Google Pay in most regions, or search for Google Pay through third-party payment providers.
Klarna: Best for markets where customers expect invoice or installment payment options. Shopify notes that Klarna can let customers pay immediately, by invoice, or through installments, depending on region and eligibility.
Additional payment methods: Best when the store needs a payment provider that is not already part of its main setup. Shopify lets merchants add payment methods by provider or payment type from the Payments settings.
Shopify payment customizations: Best for keeping checkout clean when too many options create friction. These can help rename, reorder, or hide payment methods so customers see the most relevant options first.
Final Thoughts
Shopify checkout optimization is not about installing more apps and hoping the numbers improve. It works best when every tool has a clear reason for being there.
A strong checkout should feel simple for the customer and easy for the store owner to manage. That means knowing where people drop off, removing anything outdated or messy behind the scenes, and only adding tools that make the buying experience clearer.
The same thinking applies across the whole checkout. Delivery details should remove uncertainty. Payment options should make it easier for customers to pay in the way they prefer. Post-purchase offers should feel useful and connected to the order, not like another interruption.
In the end, the best checkout apps are not the ones with the longest feature list. They are the ones that fix a real point of friction and help customers move forward with less hesitation.
For Shopify merchants and e-commerce brands, that is the real goal: a checkout that feels clear, easy to complete, and valuable without becoming crowded.
