What is ecommerce checkout? Process, types & payment methods

One out of five online shoppers abandon their carts because of an unsatisfactory ecommerce checkout process.

From the number of steps and form fields to payment options and security, every element can influence whether a customer completes a purchase or leaves without converting.

This guide will explore the ecommerce checkout process, its different types, key elements, and essential payment methods to create a better checkout experience.

What is ecommerce checkout?

eCommerce checkout is the sequence of steps an online shopper takes to convert a cart into a completed, paid order.

The checkout process starts when the customer indicates they are ready to buy, usually by clicking a "Proceed to checkout" or "Buy now" button, and ends when they receive an order confirmation.

An ecommerce checkout is where your store turns a shopper's interest into a sale. Everything before checkout is just browsing and selecting.

The checkout process sits at the intersection of several third-party integrations connecting to your online store. This includes your payment gateway, your shipping configuration, and your customer account settings.

These integrations work in the backend. All a shopper sees on the storefront is a form and a "place order" button.

How does the ecommerce checkout process work?

The checkout process varies in the number of pages or steps it uses, but the same core stages appear in almost every ecommerce store. Here's how it flows.

Not every checkout follows this exact sequence. Some platforms compress several stages onto a single page while others add steps for gift messages, delivery date selection, or loyalty point redemption.

The overall logic is to collect the information that is needed to ship, charge, and confirm the order.

Tip: Each stage is a point where the shopper can reconsider their decision to buy. The more friction at any stage (confusing labels, unexpected costs, missing payment options) or the more number of unnecessary steps, the more likely shoppers are to leave.

What are the key elements of an ecommerce checkout page?

A checkout page is made up of several components. As a store owner, you will configure most of these in your ecommerce platform while setting up.

Order summary

The order summary shows the shopper what they are buying, such as product names, images, quantities, individual prices, subtotal, estimated shipping, and taxes.

A visible order summary does not only remind shoppers what is in their cart, it also keeps the anticipation of the purchase alive while they are completing forms, which helps maintain momentum toward completing the purchase.

Contact and shipping information

The contact and shipping form collects the email address, phone number, and delivery address the store needs to fulfill the order. It is important to keep this form as short as possible.

Shipping options

The shipping options section shows available delivery speeds and their costs for the shopper can choose. This is also where one of the most common checkout problems lives.

According to Baymard Institute, 40% of shoppers abandon a checkout because the extra costs, such as shipping, taxes, or other fees, were higher than expected.

The fix to this is maintaining transparency by displaying the correct shipping cost estimates on your product page or in the cart, so the shopper arrives at checkout already knowing what to expect.

Payment form

The payment form is where the shopper enters their card details, selects a digital wallet, or initiates a buy now, pay later transaction. Your payment gateway handles the security, including encryption, PCI compliance, or fraud detection.

A well-designed payment form auto-detects card type as the number is entered, uses clear labels, shows security icons alongside the card fields, and provides specific, actionable error messages when something goes wrong.

Trust signals

Forbes reveals that 19% of online shoppers abandon a checkout because they did not trust the site with their credit card information.

Trust signals are the visual cues that tell shoppers your store is legitimate and their payment information is safe.

They include an SSL certificate (visible as HTTPS in the browser address bar), recognized payment logos (Visa, Mastercard, PayPal), security badges, and links to your returns and privacy policies.

Order confirmation page

The confirmation page closes the transaction. It should show the order number, a summary of what was purchased, the delivery address, the estimated arrival date, and instructions for tracking the order.

A clear confirmation page reduces support inquiries and sets expectations that prevent disappointment. It is one of the most under-designed pages in most stores.

What types of ecommerce checkouts are there?

The structure of your checkout, which includes the number of pages or steps and how payment is initiated, varies by platform and by configuration. Here are some of the main types:

 Guest checkout vs. Account checkout

Around 25% of shoppers abandon a checkout because the site asks them to create an account before completing a purchase.

Let's consider this statistic as an example:

Suppose 100 shoppers reach your checkout and 25 of them abandon their cart rather than creating an account; offering guest checkout directly recovers those 25 orders.

But, account holders historically spend 30–40% more per order and return more frequently. When the overall lifetime value is considered, it is possible that mandatory account checkout could generate more revenue.

The best answer to this that most online stores use is offering guest checkout by default, then inviting the guest shopper to create an account for after the order is confirmed.

For stores with strong loyalty programs or subscription products, making account creation mandatory may be worth implementing as the customer lifetime value could justify the loss of a small conversion cost.

What key payment methods should your checkout support?

Payment method coverage directly affects conversion. The right payment mix depends on who your customers are and where they are located. Here are the common payment methods most online stores should have.

Card payments

Credit and debit cards remain the most widely used payment method in most markets. Recognizable card logos (Visa, Mastercard, Amex) alongside the payment fields tell shoppers which cards you accept and signal that you are using a legitimate, recognized payment infrastructure.

Digital wallets

Digital wallets let shoppers pay using credentials stored on their device or in a browser. For mobile shoppers especially, this is the lowest-friction path to payment.

The major wallets—Apple Pay, Google Pay, Shop Pay—work independently. So you would need to enable each as a separate integration in your platform settings. If you sell to mobile-first customers, it is important to prioritize these.

Buy now, pay later (BNPL)

Buy now, pay later services let shoppers split a purchase into installments. BNPL is particularly effective for higher-priced items.

It's important to note that BNPL providers charge higher merchant fees than standard card processing, around 2–6% of the transaction value, while cards just cost 1.5–3%.

Returns can also be more complex to reconcile when a shopper has already made one or two installments.

Other methods

Bank transfer, cash on delivery, and cryptocurrency are relevant in specific markets and product categories. Payment preferences vary considerably by country. If you sell internationally, check what shoppers in your primary markets use before subscribing to more niche payment providers.

Conclusion

A well-designed ecommerce checkout removes the friction between purchase intent and a completed order. From keeping forms simple and costs transparent to offering the right payment methods and checkout experience, every element can influence whether a shopper completes their purchase or abandons their cart.

The right approach depends on your customers, products, markets, and business model. For most stores, the goal should be to make checkout as fast, clear, and trustworthy as possible while giving shoppers the payment and checkout options they expect.
