Why Do Shoppers Leave at Checkout?

Checkout abandonment is the most expensive abandonment. These customers made it through your entire funnel. They added items, clicked checkout, and started entering information. Then they left. Understanding why reveals specific, fixable problems.

This article focuses on checkout-stage abandonment specifically, not general cart abandonment. These customers were seconds away from buying.

Checkout Abandonment vs. Cart Abandonment

Cart abandonment: Customer adds items to cart but never begins checkout. Often low intent (research, comparison, wish-listing).

Checkout abandonment: Customer begins checkout but does not complete it. High intent, specific obstacle.

Why the distinction matters:

Checkout abandoners are your hottest leads. They demonstrated clear purchase intent. Something specific stopped them. Find and fix that thing.

Average checkout abandonment rate: 17-25% of checkout starters do not complete (Baymard Institute). If yours is higher, you have fixable problems.

The Checkout Abandonment Funnel

Checkout typically has these stages:

1. Contact information (email, phone)
2. Shipping information (address)
3. Shipping method selection
4. Payment information
5. Review and confirm
6. Payment processing

Abandonment at each stage has different causes.

Stage-by-Stage Analysis

Stage 1: Contact Information Abandonment

What happens: Customer sees email or phone field and leaves before entering anything.

Common causes:

Spam fear: "If I enter my email, I will get marketing spam forever."

Account detection: Email field auto-detects existing account and prompts login. Customer does not remember password.

Too many fields: Contact section asks for full name, email, phone, and more. Customer sees the work ahead and leaves.

Solutions:

• Minimal fields (email only to start)
• Clear privacy messaging ("We will only email about this order")
• Guest checkout prominent (no account needed)
• Single-field start, then expand

Stage 2: Shipping Information Abandonment

What happens: Customer entered contact info but leaves during address entry.

Common causes:

Address entry friction: Typing full address on mobile is painful. Auto-complete missing or broken.

We do not ship there: Customer discovers you do not ship to their location.

Address validation errors: Customer enters valid address but form rejects it.

Solutions:

• Address auto-complete (Google Places API)
• Clear shipping zone information before checkout
• Flexible address validation (accept minor variations)
• Save address for returning customers

Stage 3: Shipping Method Abandonment

What happens: Customer completed address but leaves when seeing shipping options.

Common causes:

Shipping cost shock: The famous "unexpected costs" problem. Customer expected free or cheap shipping.

Delivery time unacceptable: Only option is 7-10 days. Customer needs it sooner.

No free option: Customer wanted free shipping and there is none, or threshold is too high.

Confusing options: Too many shipping choices with unclear differences.

Solutions:

• Show shipping estimate earlier (product page or cart)
• Offer free shipping threshold with clear progress
• Provide expedited options at reasonable prices
• Limit to 3-4 clear shipping options maximum
• Display estimated delivery dates, not just speed names

Stage 4: Payment Information Abandonment

What happens: Customer enters payment area and leaves before or during card entry.

Common causes:

Security concerns: Customer does not trust the site with card information.

Preferred payment missing: Customer wants PayPal, Apple Pay, or other method not offered.

Card entry friction: No card scanning, no autofill, tiny fields on mobile.

Credit card fear: Customer has general anxiety about online payments.

Solutions:

• Trust badges visible near payment fields
• Multiple payment options (cards, PayPal, Apple Pay, Shop Pay)
• Card scanning and autofill support
• Professional, clean payment interface
• Option to pay with familiar services (PayPal, Klarna)

Stage 5: Review and Confirm Abandonment

What happens: Customer sees final order summary and leaves.

Common causes:

Final price surprise: Taxes, duties, or fees appear that were not visible before.

Second thoughts: Seeing everything together triggers reconsideration.

Looking for discount: Customer sees total and decides to search for coupon code first.

Solutions:

• Show all costs throughout checkout, not just at end
• Prominent discount code field (reduces "I should look for a code" departures)
• Trust elements on review page (money-back guarantee, reviews)
• Clear "what happens next" messaging

Stage 6: Payment Processing Failure

What happens: Customer clicks "Pay" and something goes wrong.

Common causes:

Card declined: Insufficient funds, card expired, fraud protection triggered.

Technical error: Payment gateway timeout, connection lost, server error.

3D Secure failure: Bank verification fails or customer does not complete it.

Solutions:

• Clear, actionable error messages ("Try a different card")
• Multiple payment methods as fallback
• Retry option without re-entering all information
• Save checkout state for recovery
• Monitor payment success rates

The Top 5 Checkout Killers

Across all stages, these cause the most abandonment:

1. Unexpected Costs (48% of abandoners cite this)

Shipping, taxes, and fees that appear late in checkout.

Fix: Show all costs on product page or cart, before checkout begins.

2. Forced Account Creation (24% cite this)

Requiring login or account creation to complete purchase.

Fix: Guest checkout as default, account creation optional after purchase.

3. Too Long or Complicated (22% cite this)

Too many steps, too many fields, too much friction.

Fix: Single-page checkout, minimal required fields, autofill support.

4. Trust Concerns (18% cite this)

Customers do not feel safe entering payment information.

Fix: Trust badges, familiar payment options, professional design.

5. Website Errors (13% cite this)

Technical problems during checkout.

Fix: Regular testing, error monitoring, fast response to issues.

Mobile Checkout Abandonment

Mobile checkout abandonment is 10-20% higher than desktop. Mobile-specific issues:

Typing friction: Full address and card entry on small keyboard.

Small touch targets: Buttons and fields too small to tap accurately.

Missing mobile payments: Apple Pay and Google Pay not enabled.

Slow loading: Checkout pages too heavy for mobile connections.

Mobile fixes:

• Enable Apple Pay, Google Pay, Shop Pay
• Large, thumb-friendly buttons (44x44px minimum)
• Minimal typing (autofill, address lookup)
• Fast-loading checkout (under 3 seconds)

First-Time vs. Returning Customer Abandonment

First-time customers abandon more because:

• Less trust in unfamiliar site
• No saved payment or address
• More friction in checkout flow
• No established relationship

Returning customers abandon when:

• Saved information is wrong or outdated
• Login required but password forgotten
• Experience is worse than remembered
• Prices or shipping have increased

Solutions:

• Make first purchase easy (guest checkout, multiple payments)
• Remember returning customers (saved info, easy login)
• Password-less login options (magic links, social login)
• Do not make returning checkout worse than first-time

Measuring Checkout Abandonment

Track abandonment at each checkout stage:

Metrics to watch:

| Stage | Benchmark Completion | |-------|---------------------| | Contact info | 85-90% | | Shipping info | 80-85% | | Shipping method | 75-85% | | Payment info | 65-75% | | Order review | 85-95% | | Payment processing | 90-95% |

If any stage is significantly below benchmark, that is your problem area.

How to track:

• Shopify Analytics: Checkout behavior report
• Google Analytics 4: Checkout funnel events
• Hotjar/FullStory: Session recordings of checkout abandoners

Recovery Strategies for Checkout Abandonment

Checkout abandoners are highly recoverable because they showed strong intent.

Email timing:

• First email: 1 hour after abandonment
• Second email: 24 hours after
• Third email: 72 hours after (optional)

Email content:

• Show the specific items they left
• Address likely objection (free shipping, easy returns)
• Clear call to action (link directly to checkout)
• Consider incentive only in second or third email

On-site recovery:

• Exit-intent popup with incentive
• Save checkout progress for return visits
• Live chat support during checkout
