An ever-changing business landscape and constantly evolving customer demands is a key reason enterprises and software vendors alike are strangling the monolith and moving to headless e-commerce. But, what is headless e-commerce exactly? 

What is headless e-commerce?

Simply put, headless e-commerce platforms have decoupled, or separated, the frontend user experience from the back-end business logic. This allows developers to use the e-commerce platform’s API to deliver the platform’s business logic (features, functionality, etc.) to whatever user experience they’d like.

You can think of the head in terms of any kind of user interface or experience. A vending machine can be a head. A desktop browser experience can be a head. A smartwatch can be a head. With headless commerce, you can update or change the head(s) without disrupting the backend 

A quick refresher on software architecture: If you think about software as a “stack” of components, the top of the stack would be the user interface, or the part that the user interacts with (sometimes this is called the “front-end”).  The rest of the stack is where the software derives all of its functionality, like the business logic and the data model (sometimes this is called the “back-end’).  

So the “head” in “headless” is the user experience. You’re accessing that back-end functionality via API, and building any sort of “head”, or user interface, for both the buyer and the admin interface on top.

What are the benefits of headless e-commerce?

Here are 5 key benefits:

1. Minimize the total cost of ownership: 

Typically on-premise solutions are sold in the form of core-based licenses. This cost model often becomes a problem for scale. As you grow and more hardware is needed to handle that growth, you need to buy more licenses. Additionally, monolithic software vendors typically release new versions a few times a year, and typically these changes are fundamental to the core. So businesses wanting to take advantage of these upgrades need to constantly review and rewrite parts of their custom code to make sure it works with the new version.

Payment Structure
Multiple application and database necessary to run at scale 
Platform is run, maintained, hosted, and scaled by Sitecore 
Updates and upgrades 
Compulsory updates a few times per year 
Continuous delivery, non-breaking API changes, new features pushed frequently 


2. Gain agility and speed:

Monolithic architecture requires developers to work with many different layers. So accomplishing a seemingly simple task, like building a new, custom promotion and displaying it in the frontend user experience, often takes backend developers a few days to implement.

Because the frontend is completely separated from the backend on a headless e-commerce platform, changes to the frontend user experience can happen a lot more quickly and with a lot less risk to the backend code.

3. Integrate efficiently and effectively:

Unlike traditional, monolithic software, headless e-commerce platforms harness the power and agility of APIs to allow you to create a tech stack unique to your business. Headless, API-first platforms enable what’s called a “best-of-breed” technology strategy. Through integration, you’re able to create your own “virtual suite” of best-in-class software. 

The beauty of a best-of-breed approach is that you’re not relying on the capabilities of an all-in-one suite option. You can choose the best-of-the-best capabilities across the board so that your software does what you need it to do for your business. And you can switch applications out as your business needs change or as the software changes.

4. Easily extend ordering to new channels, devices, customers, and more: 

With headless e-commerce, multiple frontends can be connected to the same backend. You can run and manage multiple user experiences across multiple devices without managing a mess of different systems – think wearable devices, IoT, vending machines, and more.

5. Improve time-to-value:

No matter the e-commerce platform, the back-end business logic, functionality, and capabilities comprise up to 85% of a software development process. With headless, you are starting from the point of completion which is allowing you to focus on the user experience and deliver a final solution for far less cost, time, and effort.

Why is headless e-commerce important?

When e-commerce first came about, the majority of traffic to websites came from desktop computers. As a result, the e-commerce platforms that sprung up were full-stack, monolithic architectures where the front-end and back-end were “prepackaged” and tightly tied together.

Overtime, the path to purchase has evolved far beyond simple desktop browser transactions to mobile, wearable technologies, IoT, etc. As buyers’ preferences continue to change, the ability to adapt and evolve the user experience requires the ability to control, add to, adjust, and change the user experience (aka the “heads”) more important than ever.

Headless e-commerce provides the customization capabilities, flexibility, and scalability needed to meet evolving customer needs in today’s B2B landscape.  Additional benefits for headless commerce can be found here.
