10 Shopify Checkout Abandonment Causes (And How to Fix Each One)

The Revenue You Are Losing Right Now

Checkout abandonment is not an abstract metric. It is money that was on the table and walked away. A buyer who reaches your Shopify checkout has already made the most important decision in the purchase journey — they want what you are selling. The fact that they leave without completing the transaction is almost always a store problem, not a buyer problem.

Average checkout abandonment rates hover around 65–70% across ecommerce. For some stores, particularly those with poor mobile experiences or hidden costs, it is considerably higher. If your store processes 1,000 checkout sessions per month and your abandonment rate is 70%, fixing half of that abandonment would add 150 additional orders per month — without spending a dollar more on traffic.

The starting point is understanding why buyers are leaving. Here are the ten most common causes of Shopify checkout abandonment, with specific fixes for each.

1. Unexpected Shipping Costs

Surprise shipping charges are the most consistently cited reason for checkout abandonment in every major ecommerce survey. A buyer who sees a $5.99 shipping charge at the payment step that was not visible anywhere earlier in the purchase journey feels deceived, even if the charge is entirely reasonable.

Fix: Show shipping costs as early as possible — ideally on the product page and certainly in the cart before checkout begins. If you offer free shipping above a threshold, make that threshold visible in the cart. If you charge for shipping, display it on the first checkout step rather than the final payment step. No buyer should be surprised by a charge they did not anticipate.

2. Forced Account Creation

Requiring a buyer to create an account before completing a purchase is one of the most documented causes of checkout abandonment in ecommerce. Buyers who are not already invested in a relationship with your brand will frequently choose to leave rather than register.

Fix: Go to Settings → Checkout in your Shopify admin and set customer accounts to “optional” rather than “required.” Enable guest checkout. Invite account creation post-purchase on the confirmation page, where buyers have already committed and the risk of abandonment is gone.

3. Checkout Process Too Long or Complex

Every additional step, field, or decision point in checkout adds friction. Buyers who feel that checkout is taking too long — whether because of too many steps, too many required fields, or too many choices — will abandon at a higher rate than buyers moving through a streamlined process.

Fix: Audit every field in your checkout and remove anything non-essential. Enable Shopify’s one-page checkout if you have not already. Enable address autocomplete. Remove optional fields unless there is a genuine operational need for them.

4. Security Concerns

Buyers who do not feel confident that their payment details are safe will abandon checkout rather than take the risk. This is especially prevalent for first-time buyers at stores they have not heard of before.

Fix: Display security badges, SSL indicators, and recognised payment method icons prominently near the payment form. Add a brief “Secure Checkout” label. Include a money-back guarantee statement near the checkout CTA. Make it easy for buyers to find your contact information — a visible support link tells buyers that a real business is behind the store.

5. Preferred Payment Method Not Available

A buyer who reaches the payment step and cannot find their preferred payment method will abandon at a high rate — particularly if their preferred method is something like PayPal or Apple Pay where they feel safer than entering card details manually.

Fix: Enable as many payment methods as practical for your market and audience. At minimum: major card brands, PayPal, and the relevant express checkout options (Shop Pay, Apple Pay, Google Pay). For markets with strong BNPL adoption, consider enabling Klarna, Afterpay, or Affirm. Display payment method icons in the checkout so buyers can see their options before they reach the payment form.

6. Poor Mobile Experience

Mobile checkout abandonment is consistently higher than desktop abandonment. Keyboard issues, small tap targets, page load delays, and forms that are awkward to fill on a phone all contribute to buyers giving up partway through.

Fix: Test your checkout on multiple real mobile devices, not just browser emulators. Ensure tap targets are large enough. Prioritise express checkout options (Apple Pay, Google Pay) for mobile — buyers who can complete checkout with a biometric scan instead of typing 16-digit card numbers convert at dramatically higher rates. Check that the submit button is always visible without scrolling on common phone screen sizes.

7. Checkout Page Load Speed

Slow page loads at checkout are disproportionately damaging. A buyer who has committed to purchasing will tolerate less delay at checkout than anywhere else in the shopping journey. Every additional second of load time at the checkout or payment step costs conversions.

Fix: Shopify’s native checkout is well-optimised for speed out of the box. The main risk comes from checkout customisation scripts, third-party apps that inject code at checkout, and Post Purchase widgets that fire before the confirmation page loads. Audit every app that touches your checkout and remove anything that is not delivering measurable value. Use Shopify’s Performance Dashboard to track checkout load times.

8. Payment Errors With No Clear Recovery Path

Card declines happen — but what happens after a decline determines whether the buyer tries again or gives up. Vague error messages (“An error occurred. Please try again.”) give buyers no actionable information. Many will assume their card does not work with your store and abandon rather than attempt a fix.

Fix: Ensure your checkout displays specific, actionable error messages when payment fails. “Your card was declined. Please try a different card or contact your bank.” is far better than a generic error. Where possible, surface alternative payment options (PayPal, Apple Pay) after a card decline so buyers have an immediate alternative path to completing their purchase.

9. Discount Code Issues

A buyer who has found or been promised a discount code will often abandon checkout to search for one if they cannot easily apply it, or abandon in frustration if a code they expected to work does not. The discount code field can be a significant source of checkout friction if not managed carefully.

Fix: Ensure discount codes work as expected before promoting them. If you promote a code via email, ad, or social media, test the exact code before launching the campaign. Consider using Shopify’s automatic discounts feature for promotional periods — automatic discounts apply without requiring buyers to enter a code, removing the field entirely and eliminating this source of friction. If you show a discount code field, ensure it is non-intrusive and does not draw the attention of buyers who do not have a code (the sight of the field tells buyers who do not have a code that they are paying full price while others are not).

10. Abandonment Without Recovery

Not all checkout abandonment can be prevented. Some buyers leave because they got distracted, their battery died, or they genuinely were not ready to commit. But that does not mean they are lost — if you have their email address from the checkout contact step, you have a recovery opportunity.

Fix: Enable Shopify’s built-in abandoned checkout recovery emails. Shopify automatically sends a recovery email to buyers who enter their email address in the checkout contact field but do not complete the order. The default timing is around one hour after abandonment. Customise this email with your brand’s copy, a product image, and a direct link back to their cart. For higher-volume stores, a two-email sequence (one hour, then 24 hours) with a small incentive on the second email (a discount code, free shipping) can recover a meaningful percentage of abandoners.

Addressing even half of these ten causes on your store will have a measurable impact on checkout completion rate. The team at OneOnic has worked through this checklist across dozens of Shopify stores and the patterns are consistent: most abandoned checkout revenue is recoverable with targeted, deliberate fixes rather than a complete rebuild.
