Key benefits of one-click checkout for UK businesses

Implementing a one-click payment system, also known as instant checkout, can offer advantages that may impact conversion rates and customer experience. It is a way to simplify the final stage of the customer journey.

Why one-click checkout is relevant for growing e-commerce businesses

In the competitive UK e-commerce market, customer expectations are high. Many shoppers expect fast, seamless experiences and may abandon purchases if the process is too complex.

By offering a quicker checkout option, you can reduce barriers to purchase. This may make your store more appealing to returning customers and support brand perception as efficient and user-focused.

💡As your business grows, you may start selling internationally - and that's where Wise Business can help, as it gives you the ability to receive payments using local account details for 8+ currencies and convert funds at the mid-market exchange rate with low, transparent fees.

Boost your sales with a frictionless checkout process

One-click checkout can influence conversion rates by reducing the number of steps required to complete a purchase.

A simplified checkout experience may encourage customers to complete purchases, particularly for returning users, by reducing effort and time required.

Enhance customer experience with faster purchasing

A smoother checkout process can improve the overall customer experience by reducing friction and saving time.

When customers find it easier to purchase, they may be more likely to return, which can contribute to repeat business and positive brand perception.

Reduce cart abandonment with a streamlined checkout

Cart abandonment remains a challenge for online retailers. Research indicates that long or complicated checkout processes contribute significantly to abandonment, accounting for 18% of cases in one study.¹

One-click checkout helps address this by reducing the need for repeated data entry, particularly on mobile devices where typing can be more difficult.

Understanding how one-click checkout works

The technology behind a seamless one-click payment

One-click checkout is powered by tokenisation.

Instead of storing sensitive payment details, the payment processor replaces them with a secure token. This token allows transactions to be processed without exposing card information.

How to enable a quick checkout for your customers

To enable this feature, businesses typically integrate with payment providers that support tokenisation and are PCI DSS compliant.

Customers are then given the option to securely save their details for future use.

The journey from first purchase to single-click convenience

Step 1: Initial purchase

Customers complete a standard checkout and may choose to save their details.

Step 2: Secure storage

Payment details are tokenised and stored securely by the payment provider.

Step 3: Returning customer experience

Returning customers can complete purchases more quickly using saved information.

Addressing security concerns with one-click checkout

Is one-click checkout safe?

When implemented using appropriate security protocols, one-click checkout can be considered secure. Tokenisation reduces the risk associated with storing sensitive data.

Security measures

Security typically includes:

Tokenisation
Encrypted communication (SSL/TLS)
Optional additional authentication such as 3D Secure

GDPR considerations in the UK

Businesses must obtain clear customer consent before storing personal data and provide options for managing or deleting this information.

Quantifying the ROI of one-click checkout

Conversion rate impact

Reducing checkout friction may lead to improved conversion rates. Businesses can measure this through A/B testing.

Customer lifetime value (LTV)

A smoother purchasing experience may encourage repeat purchases, which can contribute to higher customer lifetime value.

💡Managing international revenue efficiently is also important. With Wise Business, you can hold money in 40+ currencies and make international payments using the mid-market exchange rate.

Some UK retailers have reported improvements in conversion rates after simplifying checkout processes. For example, one case study reported a 37% increase in conversions after checkout optimisation.²
