One-Click Checkout: What it is and How it Works

Read this blog on your favourite platform

Checkout is the most important stage of any e-commerce buying journey. It is the stage where a shopper finally decides whether the item should be purchased or not. Reducing friction for the shopper can lead to higher conversion rates here, as it becomes easier to buy. A Cornell study noted customers increased spending by 28.5% and visited sites more often after one-click checkout was enabled.

The important thing today is to make the online buying process as easy as possible.

If you’ve carefully analysed an eCommerce store’s checkout journey, it demands shoppers to fill as many as 10-15 fields to finally land on the payments stage. While many brands have broken this process down into stages, the friction that shoppers experience continues to exist, causing high drop-offs and increased cart abandonment rates. Lengthy checkout processes are usually what hold so many businesses back from giving customers the ease of shopping they talk about and hitting their revenue goals.

That’s where a feature like one-click checkout comes in handy.

In this blog, we’ll explore what one-click checkout is, its benefits, and how to set it up on your online store with GoKwik.

The problem with traditional checkout

Traditional checkout fails mostly because it is slow, demanding, and not built for how people actually shop today. It creates friction exactly at the point where the shopper has already said "yes" by adding items to the shopping cart.

Too many steps and form fields

Typical ecommercecheckout processes ask users to complete 10-15 fields spread across multiple pages (name, email, phone, address, PIN, landmarks, etc.). UX research shows that fewer steps in a compressed checkout dramatically reduce friction.

High abandonment at the final stage

Global cart abandonment rates sit around 70–73%. "Too long/complicated checkout" is consistently reported as a top reason for abandonment. High current abandonment rates directly impact the bottom line of an online business.

Repetitive data entry for returning shoppers

Even loyal customers are often forced to retype their shipping address, billing address, and payment information every single time they buy. This repetition breaks the "I’m ready to buy" momentum and hurts the overall customer experience.

Hidden friction that costs real revenue

Each extra tap, field, or redirect adds micro-friction that compounds into lost sales at scale. For brands spending heavily on acquisition, an outdated checkout is effectively a leak in the funnel- burning paid traffic and suppressing conversion rate.

What Is One-Click Checkout?

In simple terms, one-click checkout is a fast checkout experience where a shopper can confirm their order in just one step, without repeatedly filling out long forms. After they click the checkout button, they are taken directly to the checkout page with their personal information pre-filled.

The goal is to make the shopping experience as simple as possible. It turns "I want to buy this" into a completed order in seconds. With GoKwik’s one-click checkout, a shopper only enters their details once. This information is securely stored, so for future purchases, the first step is also the final step.

WithGoKwik’s one-click checkout, a shopper only has to enter their basic shipping and billing information once on any GoKwik‑powered store- such as their name, email address, and delivery address. This information is then securely stored using GoKwik’s network intelligence, so when the same shopper returns to that brand or visits another merchant within the GoKwik network, their details are automatically recognised and pre-filled.

A typical journey looks like this:

Customers are happier when we reduce the effort of filling details

Shopper A lands on a GoKwik-partnered eCommerce brand, selects their choice of products, logs in through SSO, and enters their delivery information for the first time.
The next time Shopper A comes back to the same site, or visits another brand within the GoKwik network, the checkout form is already filled with their saved details.
Shopper A simply reviews the information, taps continue, chooses a payment method, and completes the order in just a few seconds.

Another key advantage of GoKwik’s one-click checkout is that it works as an on-site, embedded experience rather than redirecting shoppers to a separate payment page or forcing them to manually re-enter personal data. This keeps the flow smooth and consistent, giving shoppers a frictionless path to purchase and helping brands convert more high-intent visitors into paying customers.

One-Click Checkout Vs Traditional Checkout

As mentioned above, one-click checkout offers a faster, more streamlined way to complete purchases. Unlike a traditional checkout that forces shoppers through several steps and form fields, one-click checkout lets them quickly skim pre-filled information and confirm the order with almost a single click.

So, what really sets one-click checkout apart from a standard flow? The table below highlights the key differences between one-click checkout and traditional checkout:

Feature	One-Click Checkout	Traditional Checkout
Process efficiency	Single, highly compressed step to confirm and pay	Multi-step process with several pages and mandatory fields
Speed	Much faster; enables near-instant order placement	Slower due to repeated loading, navigation, and form completion
User convenience	Minimal input; shoppers mainly review and tap to confirm	High effort; users repeatedly type the same details
Data entry	Key fields are pre-filled for returning shoppers	Requires manual entry of personal and payment details each time
Abandonment rate	Lower, thanks to reduced friction and fewer interruptions	Higher, driven by long, complex and repetitive checkout flows
Customer satisfaction	Higher, as the experience feels smooth, modern, and effortless	Lower, as shoppers often feel frustrated or fatigued before completion
Conversion rates	Generally higher because barriers to purchase are minimised	Can be suppressed by friction, leading to more drop-offs
Implementation needs	Relies on a robust customer database and secure payment layer	Often needs heavier front-end flows and custom integrations to manage steps

Key Benefits Of One-Click Checkout

One-click checkout is supremely beneficial for e-commerce businesses as it encourages higher chances of purchase. However, that is not the only benefit:

Elevate Conversion Rates

The core purpose is to remove friction so more shoppers complete their purchase. By collapsing multiple steps, it leads to fewer abandoned carts. For shoppers on mobile devices, the ability to review details and confirm in seconds feels effortless, which encourages impulse buys.

Enhance Customer Retention And Brand Loyalty

One-click checkout strengthens long-term relationships. A smooth ecommerce checkout experience creates a positive memory, making shoppers more inclined to return to their favorite brand. When repeat customers know they can buy without re-entering card information or credit card information, they stay loyal.

Gain Data-Driven And Behavioural Insights

One-click checkout is a powerful engine for gathering data. Beyond just transactions, it helps with customer relationship management by tracking preferences. Brands can analyze behavior to fine-tune offers and ensure the payment card or method used is the customer's preferred one.

Support Omnichannel Purchases

It supports a consistent experience across channels. Whether on a desktop ecommerce website or via mobile commerce, the flow remains familiar.

Build Competitive Edge And Brand Differentiation

In a crowded eCommerce market, a smooth, one-click checkout clearly differentiates a brand as simple, customer-first, and modern. This convenience strengthens brand perception, encourages repeat purchases, and helps steadily grow customer lifetime value.

Improve Operational Efficiency And Resource Optimisation

A streamlined, reliable checkout leads to fewer user errors and support queries related to payment or order completion. With less time spent fixing checkout issues, teams can focus resources on growth initiatives while also getting better ROI from existing traffic and marketing.

GoKwik’s one-click checkout is designed to plug into your existing stack quickly, without forcing a major rebuild of your storefront. It works across popular platforms such as Shopify, Magento, and React Native, as well as custom setups, so you can standardise a fast, pop-up style checkout for all your customers.

Platforms And Tech Stack Supported

GoKwik’s checkout can be integrated with leading eCommerce platforms such as Shopify, WooCommerce, Magento, and other popular solutions, along with fully custom-built websites. The checkout layer operates on top of your native flow, so you do not need to change your existing design, theme, or backend logic to get started.

Step-By-Step Integration Flow With GoKwik for Non-Shopify Sellers

After onboarding, GoKwik’s team embeds a checkout plugin on your website that runs alongside your existing checkout without disrupting your current infrastructure.

Experience For New vs Returning Shoppers

New shoppers (not yet on the GoKwik network):
They are prompted to log in using their mobile number, OTP verification, or Truecaller-based authentication, and then add their address details. These details are stored securely for future sessions.
Returning shoppers (already on the GoKwik network):
They are automatically recognised and logged in, then taken directly to the address screen where their existing addresses are shown for quick selection. This allows them to skip form filling and move to payment in just a few taps.

Configuring Offers, Discounts, And Payment Mix

Once the address step is complete, shoppers land on the payments page inside the GoKwik checkout. Here, brands can:

Decide which payment options to display (UPI, cards, wallets, Pay Later, Net Banking, COD, etc.).
Apply GoKwik’s interventions to nudge more prepaid orders and reduce RTOs from COD.
Surface discounts, offers, order details, and estimated delivery dates within the checkout panel itself.

After the payment is completed, the order information is recorded in the brand’s system as well as the GoKwik dashboard, and the merchant is notified of the successful conversion.

Is One-Click Checkout Right For Your Business?

One-click checkout is broadly suitable for most eCommerce businesses in India, but it delivers the strongest results when customers buy from you more than once. It works best for categories like fashion, beauty, FMCG, and other repeat-purchase verticals, and for stores with a meaningful base of returning shoppers and mid-high AOV orders.

Because the flow reuses data from previous sessions, returning customers can skip forms, review details in a single pop-up, and confirm in seconds- cutting drop-offs and cart abandonments at the final step. Showing full order details, pricing, and discounts in one view also reduces confusion and second thoughts.

From a risk perspective, one-click checkout can still align with your standards on security, UX, and control. The key is using a solution that keeps data secure, respects your brand’s look and feel, and lets you decide which payment methods and offers are shown at checkout.

Conclusion: Getting Started With One-Click Checkout

Through a user-centric design, a focus on security, customization options, and cross-device compatibility, GoKwik's one-click checkout stands out in the market.
