Headless ecommerce isn't as scary as it sounds (or it might be, depending on the expertise of your developer). Essentially, it means that the front end of your ecommerce platform is separated from the back end, unlike a traditional ecommerce platform where the two are tightly bound.

This article takes a deep dive into what that looks like but isn't meant to be an in-depth discussion of the technical aspects of headless ecommerce. Instead, we'll focus on the business side of headless ecommerce—the benefits, challenges, and some illustrative examples.

What is Headless Ecommerce?

The technical definition: headless ecommerce is an ecommerce system in which the backend, where orders and payments are processed and data is stored, is separate from the frontend interface that the user interacts with when placing an order.

If you're considering making the switch to headless ecommerce, this definition isn't really of use. It's full of jargon and doesn't provide much insight into why or how you and your team might go about this.

Here's A Better Way To Explain Headless Ecommerce

With a lunch tray.

The lunch tray represents the backend of your ecommerce system and your lunch is the front end.

In traditional ecommerce, the lunch tray influences what you order for lunch, while in a headless ecommerce architecture you have more flexibility in what you order.

Traditional Ecommerce = Compartmentalized Lunch Tray

Go back to your grade school cafeteria, where you grab a tray for lunch. The tray has set compartments for each part of the meal.

There's a spot or two for sides, a section for a drink, and a big compartment in the middle for the main course. You have your choice of the main course, sides, and drinks, but the lunch tray always has the same layout and doesn't permit, say, ordering two mains and no sides.

If you wanted to do that, you'd need a whole new lunch tray with a different layout. This might take weeks or months for the manufacturer to make and, even after all that, you might decide you preferred the first option.

In the same way, the backend of traditional ecommerce systems limits the frontend presentation layer of your ecommerce system. The backend and frontend are tightly linked, so changes to the frontend also require changes to the backend, the same way that if you want two main courses and no sides for lunch, you need to change the lunch tray.

Headless Ecommerce Architecture = Flat Lunch Tray

In a different cafeteria, you grab a tray for lunch. This tray is flat, without any compartments.

What you order for lunch isn't limited by the compartments. The lunch tray and your order are not so tightly linked, and you don't need different trays for ordering a main course and a side one day, and two sides the next.

A headless platform is not limited by the constraints of the backend. While there is still a cA headless platform is not limited by the constraints of the backend. While there is still a connection between the backend and frontend (after all, you still need a tray to carry your lunch on), you are free to make changes to one or the other without needing to update both, or get a new tray, so to speak.

A Side Note On Content And Attributes:

Another side of headless ecommerce to consider is product attributes and characteristics.

Here's an example of product attributes and characteristics to illustrate:

Say a customer is looking for pots and pans.

Ecommerce managers and marketers might classify the pots and pans products in a few different ways depending on sales or campaigns they want to promote. For example, they might be listed separately under kitchenware, or as a set under kitchenware sets. They might be under-sale or clearance items or sorted by color, size, number of items in the set, etc.

The classification system that the attributes are part of needs to be applied the same way across every front end that is part of the ecommerce architecture. This classification structure ensures products and content are properly retrieved across the various frontends.

Let's go back to the lunch tray analogy.

With attributes and characteristics used in headless ecommerce systems, a "lunch tray" that denotes which items can be ordered and where they are placed isn't needed.

Rather than orders being based on what can fill the tray, it's based on the attributes of what you want for lunch.

For example, at lunch, you might be in the mood for something:

  1. Spicy.
  2. That has vegetables in it.
  3. Is served hot.
  4. Is a large portion.
  5. That costs less than $10.

If you input these attributes into your lunch order, you might receive a choice between a spicy Thai curry dish and a spicy minestrone. In this way-in headless ecommerce-you have more ways to offer choices to users and to make your products accessible to them.

Traditional vs Headless Ecommerce

While both ecommerce systems have their uses, headless ecommerce is arguably the superior option-for your customers, your ecommerce team, and your business overall.

Benefits Of Headless Ecommerce for Customers

Headless ecommerce provides a few key benefits for customers and, since they ultimately decide the success of your ecommerce business, you'll want to keep them happy.

1. More choices.

With headless ecommerce, you can use APIs to connect your backend to any frontend or create custom frontends, giving your customers more ways to shop beyond your website. Think social commerce, voice-controlled ecommerce, or custom frontends.

2. Ease of ordering.

By providing more frontend options, or customizing a frontend that shortens the ordering process, customers will find it easier to order. They won't need to go through your entire website checkout process when you have a custom one-click ordering front end.

3. Convenience.

Convenience is very important to customers. They will abandon an order at the first inconvenience. Keep your customers on your ecommerce platform by providing them with the ease and convenience of ordering through their preferred method.

Benefits Of Headless Ecommerce for Ecommerce Teams

Developers, ecommerce managers, and content managers all benefit from headless ecommerce as well. While planning for and developing numerous frontends might seem like extra work, the benefits of headless ecommerce balance this out.

1. Integrate with any system.

Rather than be tied to one front-end ecommerce solution, your team can use several to cover every system, so you don't miss out on the opportunities afforded by other systems. You can integrate one backend with multiple eCommerce architectures.

Lina Bustos, an ecommerce strategist and author for Ecommerce Illustrated, explains:

"Now that most ecommerce platform vendors have decoupled their front-ends from their back ends and "gone headless," headless ecommerce is more accessible than ever. Today, single-page applications and progressive web apps are table stakes, which is great for both front and back-end developers, who no longer have to coordinate everything they do with each other (something that responsive design makes even more tricky). Fast-loading pages also are great for customers and conversion!"

2. Faster updates.

As the backend and front end are separated in headless systems, updates are faster because you don't need to update both every time. In traditional ecommerce platforms, changes to the front end require difficult changes to the backend as well, but not in headless ecommerce.

3. Easier to scale.

As you don't need to update the backend for every change to the front end, it's easier to scale your ecommerce solution up or down. You can adjust your ecommerce architecture as you see fit and add new front-ends.

4. Flexibility.

Front-end developers can be more flexible and creative in their work, as they are not limited by the constraints that the backend puts on front-end development. Give your developers the freedom to come up with the latest and greatest.

5. Less Downtime.

With fewer updates to the backend when you update the front end, it follows that there is less downtime while you're performing and testing any updates. Updates are also less risky because you don't need to update the backend, so there is less risk of breaking it.

6. Reuse of Content.

With traditional ecommerce, putting your content on multiple platforms involves manually adding it to those platforms. With headless applications, you can focus on content commerce, and reuse your content in many places, because it can simply be called by an API and used across every front end.

7. More User-friendly Content Management System.

Ecommerce specialist Lina Bustos explains:

"Another great benefit of headless is the ability to give business teams a more user-friendly content management system (CMS) or digital experience platform (DXP) to load their content and make frequent (even daily) changes to the site without involving IT. This is HUGE as, in the past, sometimes even changing a home page banner could take hours of work and cost thousands of dollars through a development partner, let alone creating amazing landing pages and merchandising features."

There’s never a bad time to provide a better user experience. 

Benefits Of Headless Ecommerce for Businesses

There are benefits for businesses too, which include the continued delivery of content and convenient ordering to customers.

1. More flexibility and customization.

With headless, you can more easily adapt your ecommerce strategy to where your customers are and how they are buying. You can give them the front-end experience they are looking for. For example, if your audience moves to use more voice-controlled shopping, you can follow them thereby creating a custom front-end that allows this.

2. More agile.

Headless ecommerce keeps you agile and competitive. You can quickly implement new front-end platforms without much downtime, as well as keep up with competitors and avoid lagging behind because of long development and testing times.

3. Implement omnichannel.

With more customization, you'll be able to ensure a seamless experience across ecommerce platforms and systems that you're using as part of your omnichannel marketing strategy. This is important for boosting your conversion rate and retaining customers. Currently, only about 52% of businesses have implemented omnichannel. Be in that percentage with headless ecommerce.

Challenges of Headless Ecommerce

For all the benefits of headless ecommerce, there are challenges that ecommerce teams will need to consider.

1. Managing Roles And Responsibilities

With both traditional commerce and a headless ecommerce solution, many team members are involved in implementing, maintaining, and improving the commerce experience for customers. This can involve marketers, ecommerce managers, content managers, and front-end and backend, developers.

In traditional ecommerce, roles are easily defined because everyone can work on their task independently. For example, content managers can update content without necessarily needing input from developers.

In headless ecommerce, team members need input from each other, especially when ensuring the user's journey is coherent and seamless. This might slow down workflow in the short term, but it can benefit your team as well because, by collaborating with team members in different departments, they can avoid fishbowl thinking.

The main way to avoid a slowdown is to define workflows that minimize back and forth and streamline content, development, and user journey updates.

2. Content Managers And Marketers Are Less Independent

Because the front end requires custom coding by developers, marketers aren't as free to go into the system and add and update content as they would with a traditional CMS and digital commerce platform. They will require support from a developer, which can be time-consuming and can cause a loss of agility.

The best way to tackle this is the same as above. Define a workflow that allows marketers to be as agile as possible.

3. Additional Work For Front-end Developers

Without a default front-end, developers need to build a custom one for each application or front-end in use. This is more work up front, and this process is ongoing as you add more applications and as maintenance is required.

Time management will become more important for front-end developers, as will allocating time for testing and maintenance. You'll also want to make sure you're following UX best practices for each channel.

The Birth Of A New Generation Of Headless Ecommerce: Microservices

With headless ecommerce now so common, there's the next generation of headless ecommerce: microservices. This headless approach goes steps further than just separating front and back and starts chipping away at the commerce platform itself.

To get insight on this topic, I reached out to the aforementioned Lina Bustos, an ecommerce specialist and author for Ecommerce Illustrated. Here's her explanation of microservices and where she sees the new generation "headed":

"Because most commerce platforms are deployed as one system (monolithic code), all pieces of the platform such as catalog, cart, checkout, customer accounts, pricing, payments, and promotions are all tightly woven together. This means that any changes or updates to the platform or content impacts this large block of code, and can potentially break something anywhere in the platform. IT has to be very careful about managing the commerce application, and business users often are restricted from making updates independently (like adding promotions, changing pricing, or creating new categories).

With microservices, a promotions service (for example) would be its own application. And, like with a headless CMS, business users could (with the right business user tooling) add, modify, delete and schedule promotions independent of IT. 

The microservice could also be extended to new touchpoints and experiences, like an airport vending machine or pop-up shop, so customers could apply the same discounts from the online shop anywhere they encounter the brand or retailer, and self-checkout through their mobile phones (connecting to cart, checkout, and payment microservices).

Microservices can also scale independently, which helps site performance and uptime. Net-a-Porter, for example, built a microservices system to support the traffic spike for their twice-annual clearance sales (events that would ALWAYS bring down the site).

With analysts recommending IT and business teams to choose more modular platforms to run ecommerce, and more vendors embracing microservices architecture, I predict we'll see more and more online merchants (large and small) using them in 2023, and blending commerce with unconventional touchpoints like voice assistants, chatbots and in-store digital."

Importantly, Amplience has a way to plan workflows so that marketers, content teams, and developers can plan launches and schedule milestones together. Roles and responsibilities are defined and deadlines are noted. This makes it easy to plan content updates, ecommerce updates, and campaigns.

The Future of Headless Ecommerce

These days, ecommerce conversions are hovering at only 2.86% globally. This can sink an ecommerce store in no time. This means it's more important than ever to meet your customer's needs by tailoring your ecommerce solution to them. 

One of the easiest ways to do that is by comparing headless ecommerce platforms to traditional ecommerce platforms. Not enough companies are using a headless storefront yet and, as a result, they are having trouble keeping up with competitors that are. 

This is the way ecommerce is heading, and ecommerce managers should implement it early to manage the challenges that come with it and keep their heads on straight (see what we did there).
