Last Updated:

Did you know that 70.19% of online shoppers abandon their carts before completing a purchase?

That staggering statistic means for every 10 customers who add items to their cart, only 3 actually check out.

With Shopify powering 10.32% of all global e-commerce stores, that’s one out of every ten online shops, getting your Shopify checkout setup right isn’t just important, it’s revenue-critical.

In the US alone, Shopify dominates 30% of the e-commerce platform market, making proper Shopify checkout configuration essential for tapping into this massive opportunity.

As someone who’s helped over 200 merchants optimize their Shopify stores, I’ve seen firsthand how a properly configured checkout can transform abandoned carts into consistent revenue streams.

This guide cuts through the noise to deliver the exact steps you need—no fluff, just actionable strategies that work in 2025.

Key Takeaways That’ll Transform Your Checkout Experience

Your checkout page is leaking $260 billion annually across the US and EU, imagine what fixing just 10% of that could do for your business.
43% of shoppers abandon carts simply because they were “just browsing” but with the right checkout triggers, you can convert many of these window shoppers.
August 28, 2025 is a hard deadline for Shopify Plus stores, if you miss it, you lose all custom checkout scripts permanently.
Mobile checkout optimization isn’t optional anymore; 79% of smartphone users have made an online purchase in the last 6 months.
Adding just one trust badge can increase conversions by up to 15%, but most stores place them in the wrong location.

Why Your Shopify Checkout Setup Directly Impacts Revenue

Your checkout process isn’t just a transactional step, it’s the final conversion checkpoint where revenue is made or lost. Consider these eye-opening statistics:

The average cart abandonment rate sits at 70.19% across all industries, meaning seven out of ten potential customers leave without purchasing.
$260 billion in recoverable orders is lost annually in the US and EU alone due to poor checkout experiences.
43% of US shoppers have abandoned a cart within the last three months specifically because they were “just browsing,” representing a massive untapped opportunity.

When Shopify processes $300 billion in gross merchandise volume (GMV) annually across its 5.5 million active stores, even a 1% improvement in checkout completion translates to $3 billion in additional revenue.

This isn’t theoretical, proper Shopify checkout setup directly impacts your bottom line.

Pre-Setup Essentials: What You Need Before Touching Settings

Before diving into your Shopify checkout setup, gather these critical components:

Required Documentation

Business license (for certain payment gateways)
Tax identification number
Proof of address
Bank account details for payouts

Payment Gateway Considerations

Choose wisely—your payment processor affects:
Transaction fees (typically 2.4% + $0.30 per sale)
Supported countries and currencies
Payout speed (2-3 business days standard)
Fraud protection capabilities

Pro Tip: Shopify Payments eliminates third-party gateway fees but isn’t available in all countries. For global stores, consider multi-currency solutions like PayPal or Stripe.

Legal Compliance Requirements

Privacy policy (mandatory for GDPR/CCPA compliance)
Refund policy (clearly visible during checkout)
Terms of service
Age verification (for restricted products)

Step-by-Step Shopify Checkout Configuration

Accessing Your Checkout Settings

Log into your Shopify admin dashboard and Navigate to Settings

Navigate to the “Checkout” section

Warning: As of 2025, Shopify has restricted certain customization options for non-Plus stores.

If you need advanced features, consider upgrading to Shopify Plus before August 2025.

Customizing the Checkout Experience

Critical 2025 Update: Shopify is transitioning to a new checkout experience fully controlled by the platform, with mandatory adoption by August 2025 for Plus stores and August 2026 for standard stores. Here’s what you can still customize:

Branding elements: Upload your logo, set primary color
Checkout language: Multiple language support
Contact information: Required vs. optional fields
Order processing: Automatic fulfillment options

Proven Tactic: Add trust badges between the payment method selector and the “Complete order” button, this placement increases conversions by 12.7% compared to header/footer placement.

Payment Gateway Setup

In Settings > Payments, select your preferred gateway

Choose a payment method

For Shopify Payments: Enter banking details and business information

For third-party gateways: Input API credentials

Crucial 2025 Feature: Shopify Plus merchants can now establish minimum and maximum order value limits in Checkout Blocks.

Must-Do:Enable Shop Pay, stores using this accelerated checkout option see 1.7x higher conversion rates on mobile.

Shipping Rate Configuration

Avoid these common pitfalls that cause 18% of cart abandonment:

Hidden shipping costs revealed too late

Limited shipping options

No delivery date estimates

Optimal Setup:

1. Create tiered shipping rates (free over $50, standard $4.99, express $9.99)

2. Enable real-time carrier calculated rates for accuracy

3. Add delivery date estimates using apps like “Shipping Date Calculator”

Tax Settings

Shopify automatically calculates sales tax in 50+ countries, but you must:

1. Verify your business address accuracy

2. Set up tax overrides for specific products

3. Configure tax exemptions for wholesale customers

2025 Update: New EU digital services tax requirements affect stores selling downloadable products, consult a tax professional if selling digital goods internationally.

Shopify Plus Deadline for Order Status and Thank You Pages

Here’s what keeps e-commerce developers awake at night: Shopify Scripts deprecation deadline has been extended to June 30, 2026, but Plus stores must upgrade Thank You and Order Status pages by August 28, 2025.

What happens if you miss it?

All existing `checkout.liquid` and Additional Scripts customizations will be permanently removed

Your store will automatically upgrade to Shopify’s new checkout system

Custom functionality (like volume discounts at checkout) will break

Migration Path:

1. Audit all current checkout customizations

2. Recreate essential functionality using Shopify Functions (replaces Scripts)

3. Test thoroughly in development environment

4. Implement before deadline

Expert Insight: The new UI extension capabilities for checkout customization in 2025 actually offer more robust options than Scripts, but require relearning the implementation process.

Proven Tactics to Reduce Cart Abandonment

Implement these evidence-based strategies immediately:

The Essential Fixes

Enable guest checkout (forces 24% abandonment when disabled)

Button color (green converts 14% better than red for “Complete Order”)
Trust badge placement (mid-checkout outperforms header placement)
Field requirements (removing “Company” field boosts mobile conversions by 8%)
Testing Your Shopify Checkout Like a Pro

Never launch without these tests:

1. Test Order Process:

Create test orders with Shopify’s built-in test mode
Verify all payment methods work correctly
Check email notifications at each stage

2. Mobile Testing:

Test on actual devices (not just browser emulators)
Verify form fields don’t require zooming
Check loading speed (aim for <2 seconds)

3. User Testing:

Record 5-10 users completing checkout
Note where they hesitate or get confusedImplement changes based on real behavior

Pro Tip: Use Shopify’s “Checkout Extensibility” to add custom validation without breaking the new system.

Monitoring & Optimization: The Never-Ending Process

Your Shopify checkout setup isn’t “set and forget.” Track these metrics weekly:

Metric	Healthy Benchmark	How to Improve
Checkout completion rate	>30%	Simplify form fields
Mobile conversion rate	65% of desktop	Optimize for thumb zones
Payment method selection	Shop Pay >40%	Promote accelerated checkout
Abandonment at payment step	<22%	Add more payment options

Advanced Tactic: Implement session recordings to see exactly where users drop off, tools like Hotjar reveal issues you’d never spot otherwise.

Frequently Asked Questions

Can I completely redesign my Shopify checkout in 2025?

What happens if I miss the August 2025 deadline for Plus stores?

If you miss the August 28, 2025 deadline, Shopify will automatically upgrade your store, permanently removing all existing checkout.liquid customizations and Additional Scripts.

How do I add gift wrap options during Shopify checkout?

You’ll need a checkout extension app like “Gift Wrap & Message” that leverages Shopify’s new Functions API.
