Headless Commerce

Projected to grow at a compound annual growth rate of 20.5% — reaching $32.1 billion by 2027 — headless commerce is one of the fastest growing trends in ecommerce today. 

In this guide, we’ll explore the key differences between traditional and headless commerce, what benefits you can expect from a headless solution, and how our own merchants are reaping the rewards of a headless ecommerce framework.

Headless commerce vs. traditional ecommerce: What’s the difference?

Making the choice between traditional ecommerce and headless commerce starts with knowing your business needs and capabilities. Let's explore the key differences between traditional and headless commerce and how to determine which is best for your business.

Whichever model you choose, BigCommerce is here to support you. We offer the flexibility to create custom, cutting-edge user experiences through headless ecommerce architecture while maintaining robust, out-of-the-box functionality for traditional commerce setups. 

What is headless commerce?

Headless commerce is the decoupling of a website’s frontend presentation layer (which includes elements such as text, colours, styles, images, and buttons) from the backend functionality (pricing, infrastructure, security, checkout, etc). 

In between the frontend and backend system lives a layer of powerful APIs (application programming interfaces). These APIs act as the middleman between the two systems, allowing ecommerce businesses to plug and play various frontend solutions without the risk of impacting the backend commerce functionality.

This means that businesses have full freedom and flexibility to optimise the customer experience through multiple unique storefronts. They can update web copy and images across their site, or even extend these experiences to new channels such as mobile apps, kiosks, and IoT devices. And all the while, the backend system continues to support all commerce functionality.  

In short? You can create and modify unique ecommerce experiences when you want and how you want.

What about composable commerce?

Amid ever-changing customer behaviors, trends, and advancements in technology, headless commerce has paved the way for a new level of flexibility and agility. But some businesses have even taken it a step further. 

Some people have used the terms “headless commerce” and “composable commerce” interchangeably. However, headless commerce is actually a component of the bigger composable commerce umbrella. 

Headless commerce refers to the breaking down of an all-in-one commerce system by decoupling the frontend and backend layers to operate independently. Composable commerce, however, means that every component of the tech stack is independent, and can therefore be “composed” to create the most optimal, customised solution for your business. Like a set of Lego blocks, every element of the tech stack is modular and pluggable, allowing businesses to completely tailor the customer experience. 

In essence, headless technology is a cornerstone of composable commerce, working in tandem with the other principles of MACH (Microservices, API-first, Cloud-native SaaS, headless).

What is traditional ecommerce?

For many years, the go-to structure for many ecommerce businesses has been an all-in-one monolithic structure, which ties together the frontend and the backend systems. Before headless entered the picture, many brands used a monolithic strategy, and many agencies even recommended it for enterprise and well-established businesses.

The benefits? For many businesses, a monolithic ecommerce architecture offers a quick and easy setup and a faster time-to-market. Many traditional ecommerce platforms offer storefront templates and drag-and-drop features that allow businesses to quickly launch their site.

The downside? These monolithic solutions can lack the flexibility and agility for brands that want to innovate on the fly and make quick site changes down the line. Plus, since the frontend and backend are linked together, any changes made to either end can negatively impact the other. 

But that’s not to say a traditional ecommerce solution isn’t a good choice for some businesses! If you’re looking to get your site up and running quickly, and you don’t anticipate needing a lot of customisation, a traditional ecommerce platform might be the right move for you.  

What are the benefits of headless commerce?

Headless commerce opens up a world of possibilities for brands that are looking to adopt a content-led strategy. By adopting this approach, your business can: 

• Reduce tech debt and decrease implementation time for development teams

• Discover more flexibility to create seamless shopping experiences that increase conversions

• Design content rich experiences to cater to customer needs

• Support emerging technologies for the scale of your business

Let’s explore these four benefits of headless commerce and which of your team members each will specifically impact.

Reduce tech debt and decrease implementation time for development teams.

Who it helps: developers

When it comes to decreasing costs and time to market, headless commerce can be a game-changer. 

By decoupling the frontend from the backend, your developers can craft multiple customer-facing independently from the commerce engine, which means two things: 1) Frontend and backend teams can innovate and deploy solutions quickly, without waiting on the other, and 2) You can reduce the expenses involved in what was once a long, arduous development process.

As a result, headless allows for faster iteration and quicker time-to-market for new projects, whether you're launching internationally or rolling out omnichannel strategies. And thanks to the flexible tech stack, it's a breeze to implement custom features and functionality. 

More flexibility to create seamless shopping experiences that increase conversions.

Who it helps: director of ecommerce and ecommerce managers

Considering companies with a strong omnichannel approach see a customer retention rate of about 89% — compared to 33% for those with a weak omnichannel approach — taking a single-channel approach is no longer sufficient.  

Luckily, going headless means you can promote your content across the channels you have now — as well as new ones you add in the future. Since you can modify your frontend without affecting your backend, you have the freedom to add multiple online and offline experiences, whether it be a mobile app, an online marketplace like Amazon, or a social media platform like Facebook or Instagram. All the while, your commerce engine is consistently running on the backend.

Creating these seamless shopping experiences also has the potential to drive more conversions and lower customer acquisition costs. Amid an increase in paid advertising, headless commerce offers a new way to increase organic traffic: through a content- or experience-led strategy. By testing various frontend solutions while running the same backend — and vice versa — you can determine which channels attract the most traffic and improve conversion rates faster than traditional ecommerce models. 

Design content rich experiences to cater to customer needs.

Who it helps: ecommerce merchandisers or marketers

With a traditional monolithic system, you may find your options limited when it comes to developing new experiences on the frontend. 

However, with a headless solution, you can integrate new technologies and adapt to new trends as they arise. As a result, your marketing team will have full freedom to innovate and build multiple user experiences across different channels — without hurting your backend processes.

Moreover, a headless ecommerce platform houses content centrally and is able to deliver it anywhere via APIs. This method allows for much faster load times than traditional ecommerce platforms and lends itself to exceptional customer experiences.

Support emerging technologies as you scale your business.

Who it helps: IT executives

As new technologies and trends emerge, you’ll need to be able to future-proof your brand. Luckily, headless commerce allows you to quickly adjust your frontend without needing to replatform on the backend. In a headless environment, brands can seamlessly test and implement new technologies, giving developers the freedom to innovate without being constrained by traditional CMS limitations. 

The frontend, or “head,” of your ecommerce site can be tailored for optimal content delivery by connecting to a CMS, DXP, or IoT device designed for content- or experience-led commerce. This setup allows you to swap out the frontend as needed without disrupting backend operations. This way, you can focus less on developing and more on scaling your business.

What are common use cases for headless commerce?

Whether you prefer WordPress, Contentful, Contentstack, Bloomreach, Adobe Experience Manager or other CMS/DXPs, PWAs or CRMs — headless commerce works in just about any use case. All you need is an API connection to decouple the platform’s presentation layer and then plug the platform in to where you need it to work.

Let’s take a look at some of the most common use cases for implementing a headless framework.

Custom solutions.

A major reason to choose headless may be that you have big ideas that no one system can provide out of the box. Maybe you’ve found the customisation you need by working with open-source platforms in the past but couldn’t handle the long development cycles and maintenance. Or maybe you’ve worked on SaaS but found it was limiting your innovation. 

With headless, you can keep the customisation and lose the cost and upkeep. 

Headless provides an Open SaaS experience that’s the best of both worlds. APIs enable the flexibility you need to think beyond the limits of any one platform or technology and seamlessly connect systems in a more modular fashion. 

Content Management System (CMS).

When the headless architecture is paired with a CMS, it makes for a powerful combination. In these cases, the ecommerce platform is decoupled from the presentation layer, so a brand can use popular CMS solutions like WordPress, DXPs like Bloomreach, or custom frontend solutions for unparallelled customer experiences that increase conversion.

Especially if you’re taking an omnichannel approach, pairing headless commerce with a headless content management system is the way to go. Using a single CMS, you can create channel-specific content and various user interfaces with APIs powering your frontend and backend. 

Digital Experience Platform (DXP).

A DXP is a type of software that enables companies to quickly digitise and provide an improved customer experience. Combining a DXP with a headless CMS solution can result in a strong foundation.  

The value in this partnership comes from the flexible, API-driven content and its capability to integrate with other services. This combination allows developers and marketers to work separately and also leaves room for additions and edits without affecting the project flow.

Progressive Web Apps (PWA).

Progressive web apps (PWA) are web applications that use the latest web capabilities to deliver a native, app-like experience to users. They are regular web pages or websites but appear to the user like traditional applications or native mobile apps. By combining the capabilities of websites and mobile software, PWAs create an immersive user experience that can lead to higher conversion rates and more time spent on site.

BigCommerce is committed to providing merchants the capability to leverage PWAs. We offer integrations with DEITY Falcon and JMango360, as well as a Gatsby-Netlify CMS template to jump-start developing a serverless PWA storefront.

In addition, BigCommerce recently launched Catalyst, our next-generation storefront technology for developers and agency partners. With a fully integrated storefront reference implementation based on Next.js and React, Catalyst provides a full, end-to-end guest shopper experience that is pre-wired to our platform, based on the Next.js frontend framework. Catalyst will be the default starter for new composable builds, utilising the latest features within Next.js and our GraphQL APIs.

How to get started with headless commerce

If these use cases and benefits are resonating with you, you might be wondering how to start implementing a headless framework. Here’s a step-by-step approach to help you get going.

Determine if headless commerce is right for your business.

While the perks of a headless solution are many, this type of framework isn’t for everyone. Many businesses still use a traditional monolithic model, and many agencies still recommend a monolithic strategy for enterprise and well-established brands.

But if you’re looking for greater flexibility, scalability, and agility in your ecommerce platform, a headless solution may be worth considering. Here are few criterion to help you decide whether to make the switch:

• You’re a content-driven brand

• Your brand is experience-driven and needs the ability to implement personalisation, AI or AR capabilities

• You’re looking to create seamless digital experiences across multiple customer touchpoints and devices

• You have multi-site or international selling needs, serving up multiple frontend experiences powered by the same backend

• You already use a CMS and want to add commerce

• You’re already selling online and have a separate site for content and need to be able to merge the two

Understand the necessary architecture for going headless.

To get the most value out of your headless architecture, it’s crucial that you first understand how its architecture is unique from a traditional commerce site. 

On the backend, a headless commerce solution comes equipped with all the essential functionalities to run your store, such as inventory management, pricing, catalogue, and checkout. But unlike traditional legacy systems, headless commerce separates these backend elements from your website's frontend, granting both your developers and business users the freedom to continuously innovate and build unique experiences across various customer touchpoints. 

This flexibility means your teams can build unique, content-led experiences that convert more effectively, leading to higher revenue growth. Understanding this architecture is key to leveraging headless commerce to exceed your business goals year-over-year.

Identify your frontend storefront options and backend ecommerce provider. 

To achieve the most optimal headless architecture, you’ll need the right frontend for your target audience, as well as a strong backend to power your commerce engine. 

For the frontend, consider options like custom-built solutions using frameworks like React or Vue.js, or popular CMS/DXP platforms such as WordPress or Drupal. Choosing the ideal frontend will largely depend on the size of your business, your target audience, and the skill set of your developer team. 

On the backend, you’ll need a robust ecommerce provider that offers core commerce functionality such as inventory management, checkout, and security. Luckily, BigCommerce offers all of these features — and more — out of the box. We allow you to create unparallelled unique customer experiences powered by our back-end commerce platform with the most headless integrations, so you never have to replatform again.

Examples of headless commerce in action 

It’s often very difficult to tell if a brand is using headless commerce as a strategy just by looking at it. This will only become more true as headless ecommerce becomes more mainstream and loses its URL redirect to a checkout page.

For the time being, let’s look at a few headless commerce examples.

Black Diamond. 

Case Study: Black Diamond

When mountain gear brand Black Diamond turned to BigCommerce, the company was seeking to create a clear buyer journey from homepage to checkout, weaving its brand content throughout the customer experience.

With the flexibility of a headless framework, Black Diamond achieved an independent, yet cohesive administration of its EU site while leveraging common product data, a single CMS instance and other key services. Black Diamond was able to house its US and EU site under one ecommerce roof and uniquely serve its customers across various markets.

Together with a flexible, new CMS, BigCommerce gave Black Diamond the freedom to execute on its vision without a heavy dependance on developers. With the freedom to manage its site directly, Black Diamond was able to leverage its technical team to integrate a PIM setup as well as an ERP system.

Burrow.

Case Study: Burrow

As a brand specializing in modular, customisable furniture, Burrow needed a headless architecture that would reflect this same flexibility. After reaching $3 million in sales in 2017, the team sought a modular, flexible ecommerce solution that could keep up with business growth.

Turning to BigCommerce, Burrow found the scalable backend system it needed to customise its site quickly and easily. The reliability and lack of maintenance freed up its team to focus more on marketing-focused updates to the site. They were also able to utilise a custom CMS on the frontend, enabling them to create the kind of user experiences they wanted for their customers.

Since launching with their headless solution, Burrow saw a 30% increase in conversion rate in only two months and a 50% increase in site speed and performance. 

White Stuff.

Case Study: White Stuff

Offering customers a better experience through performance improvements was the initial motivation factor that prompted White Stuff, a British apparel and lifestyle brand, to replatform to BigCommerce. It knew speed and functionality were constrained by the technology it was using, so the solution was to separate the front- and back-ends by going headless. 

“I was really adamant about the role of speed on the site because of the need with fashion retail to bring content to life through the increased use of video and rich imagery that a customer wants to experience our brand,” said Steve Borg, Technology and Transformation Director at White Stuff. “So that really drove some decisions around a headless implementation. We felt that that was the best way to retain a lightweight front-end and give us the maximum chance of consistently being able to provide that fast experience for customers.”

Combat Corner.

Case Study: Combat Corner

Before implementing a headless commerce architecture, Combat Corner faced significant challenges with its previous ecommerce platform, including slow page-load times that hindered user experience and difficulties in managing and updating the site effectively. 

After migrating to BigCommerce, Combat Corner implemented a headless solution with a React frontend on WordPress Engine’s Atlas platform. This integration not only improved site performance and user navigation but also provided the flexibility needed to manage and update the online store efficiently, ensuring a seamless customer experience across devices.
