Cart abandonment at checkout is the highest-cost conversion failure in ecommerce — the customer has already decided to buy. Global average cart abandonment rates hover around 70%, and the checkout experience is responsible for a meaningful share of that. This playbook covers the core strategies that move the needle, plus links to deeper dives on specific tactics (trust signals, mobile, payment methods, Shopify Plus customization) if you want to go further on any one of them.
Core Checkout Optimisation Strategies
Simplify the flow
Reduce the number of steps, pages, and form fields to the minimum required to complete the transaction. One-page checkout consistently outperforms multi-step flows. Remove fields that aren't needed for order fulfilment — phone numbers and forced account creation are the most common unnecessary requirements.
Eliminate cost surprises
Unexpected shipping costs at the payment step are the leading cause of checkout abandonment. Show shipping costs, estimated delivery windows, and taxes as early as possible — ideally at cart level. If you offer free shipping above a threshold, make it visible throughout the buying journey.
Expand payment options
Express checkout options (Shop Pay, Apple Pay, Google Pay, PayPal) and BNPL methods (Klarna, Afterpay, Shop Pay Instalments) directly address the two most common reasons customers abandon: they don't have their card handy, or they want to spread the cost. Adding digital wallets to your flyout cart — not just the final checkout page — gives customers an instant-checkout path even earlier in the journey. See our dedicated guides on BNPL, Google Pay, and one-click checkout for setup specifics on each.
Build trust at checkout
Security badges, visible SSL indicators, a clearly linked returns policy, and recognisable payment logos all reduce the anxiety that causes last-moment abandonment. PCI compliance is a baseline requirement — Shopify provides Level 1 PCI compliance by default. See our deeper breakdown of checkout trust signals and policy transparency for specifics.
Optimise for mobile
More than half of ecommerce traffic is mobile, and mobile checkout completion rates consistently lag desktop. See our dedicated mobile checkout optimisation guide for the specific fixes that matter most on smaller screens.
Offer guest checkout
Requiring account creation before purchase is one of the highest-friction decisions a merchant can make. Guest checkout should always be available. Account creation can be offered post-purchase, when the customer already has a positive experience to anchor the relationship.
Add revenue tactics beyond friction reduction
Once the fundamentals above are handled, upsells, cart recovery flows, and flexible shipping options add incremental revenue per checkout rather than just reducing abandonment. See our checkout revenue tactics guide for the specifics.
Post-Checkout: Delivery, Returns, and Loyalty
Checkout optimisation doesn't end at payment confirmation — the delivery, returns, and post-purchase experience all feed back into whether a customer returns and completes checkout again with less hesitation next time.
Delivery experience
Fast shipping and a considered unboxing experience matter for repeat purchase. Fulfilment partners like ShipBob, ShipStation, and Narvar help manage delivery expectations and carrier logistics at scale. Buy Online, Pickup In-Store (BOPIS) continues to grow as customers look to avoid shipping costs entirely where a physical location is available.
Frictionless returns build pre-purchase trust
A clear, easy return policy — for guest and account customers alike — reduces checkout hesitation before the sale even completes, not just after. Prominently displaying your returns policy in your site navigation, not burying it, measurably improves conversion.
Loyalty and repeat purchase
A one-time purchase carries the highest cost of acquisition; a returning, loyal customer reduces that cost at every subsequent conversion. Loyalty programs and early access to new collections increase repeat conversion — but pace these deliberately. Repeating a discount cycle too quickly causes sales fatigue, conditioning customers to wait for the next deal rather than buying at full price.
Shopify Plus: Customizing the Checkout Itself
For Shopify Plus merchants, Checkout Extensibility and Shopify Functions open up genuine checkout customization — branding, custom fields, post-purchase upsell pages, and custom business logic like B2B payment terms. See our full breakdown of Shopify Plus checkout customization options, and if you're evaluating who should build it, our guide to choosing a Checkout Extensibility agency.
Measuring What's Working
Track checkout initiation rate, completion rate, and payment success rate. Segment by device type and payment method to identify where drop-off is concentrated. Use session recordings (Hotjar, FullStory) to identify specific friction points — rage clicks and form abandonment patterns often reveal fixes that analytics alone won't surface.

Frequently Asked Questions
What's the single highest-impact checkout change most stores can make?
Showing shipping costs earlier in the buying journey — unexpected costs at the final step are consistently the leading cause of checkout abandonment.
Should I always offer guest checkout?
Yes. Forced account creation before purchase adds friction at the exact moment you want none — offer account creation after the sale instead.
How many payment options should I offer?
Enough to cover your customers' actual preferences — typically 1-2 express wallets, a BNPL option, and standard card payment. More isn't always better if it clutters the page; match options to what your specific audience actually uses.
