Headless commerce: Innovative eCommerce app development for tomorrow’s market leaders

Mar 18, 2021 · 7 Min. lesen

If you’re still using a legacy eCommerce platform, you might be leaving a lot of money on the table. That’s because your software limits you in creating shoppable moments at trending and emerging consumer touchpoints.

Today’s buyers embrace shopping on mobile, through voice assistants, and in self-service kiosks. The longer you stay with a traditional desktop-locked online store, the more of your customers will buy from your competitors.

Just take a look at your online store stats. Over 50% of your web traffic may already come from mobile. At the same time, your mobile conversion rate can’t be nearly as good as desktop. If you see that consumers are visiting your store on mobile yet aren’t converting, it’s time to move to headless commerce. It can help you close your mobile conversion gap and experiment with new sales channels.

Let’s look at what headless commerce is, how it works, and how you can implement it without hiring an Amazon-grade engineering team.

Why choose headless eCommerce over traditional?

To stay competitive, you now should consider the shopping experience to be your product as much as the goods you sell. In this view, you can’t rely on your eCommerce platform to take care of it anymore. It’s time to get the responsibility for keeping up with customer expectations back to your team.

With headless commerce, you get full control over your customer experience across all touchpoints. You're no longer constrained by templated user interfaces provided by the platform. Your brand becomes flexible and able to adapt to the ever-changing customer needs fast. You get a chance to catch emerging engagement opportunities and create shoppable moments that you’d definitely miss with a legacy eCommerce system.

Now, let’s consider what makes headless commerce such a flexible and powerful tool. Knowing how it works will help you understand how it’s different from traditional eCommerce websites.

How does headless eCommerce architecture work?

A headless architecture is a relatively simple concept. As illustrated in the diagram, the whole eCommerce application consists of a set of decoupled systems (frontend and backend) that communicate via an API.

The term headless refers to the eCommerce application that runs on the backend of your online store (server-side). It can represent a headless CMS, or an eCommerce platform engine, or a set of custom microservices with third-party integrations. This single backend app encapsulates and executes all of the business logic and stores data.

Instead of a user interface (UI) that should have served its ‘head’, the headless backend app has an application programming interface (API). The API enables connection and data exchange between the backend app and an arbitrary number and type of user-facing applications (frontends).

The agility of headless architecture comes from the separation of the frontend from the backend. Numerous user interfaces can be developed, added, removed, and updated independently from the backend app and each other. All they need to become a part of the entire system is to call the API of the backend app.

Headless architecture gives you the green light to quickly update customer-facing functionality and content based on your business needs. It makes it possible to change user interfaces safely without any harm to the underlying business logic and workflows of your eCommerce application. And vice versa, the entire backend can be modified or even replaced without breaking functionality on the frontend, as long as the new system provides the same API.

To implement headless commerce you’ll need a vision, an engineering team, and a UX/UI designer. At the first glance, it may seem to be too complicated for a small or medium-size retail business. It also may seem that going with headless eCommerce would be much more expensive than installing and customizing a traditional eCommerce platform. But is that true?

How can you implement headless commerce?

Earlier headless commerce was a prerogative of corporations having in-house engineering teams or smaller digitally native brands. Now, it’s mainstream. It’s affordable for any merchant wanting to keep up with customer expectations, deliver innovative shopping experiences, and experiment with different sales channels.

Today developers can use a variety of open-source software frameworks, pre-built code packages for eCommerce apps, and special software development kits (SDK). The advancement of technologies democratized custom eCommerce application development and sped it up. It means that headless commerce is not about building homegrown software from the ground up anymore.

Building a headless eCommerce app now can be equal in cost and complexity to customizing an open-source CMS or third-party eCommerce software. But it gives you a future-proof system with lower maintenance costs and higher conversion potential. To estimate the scope of work, you should know that building user interfaces will anyway be on you, but you’ll be able to use some off-the-shelf options for the backend app.

How to approach eCommerce app development?

As desktop and mobile remain the main online sales channels, your first task will be to create a system that performs effectively on both. Luckily, you don’t have to create a separate mobile app for this. Instead, you’ll build a single progressive web application (PWA) that will provide a slick storefront for all devices.

PWA is a browser-based app that shows users different interfaces depending on the platform and device they access it from. You shouldn’t confuse it with shrinking your website to fit a small screen. It’s rather about providing a native app-like user experience through the mobile web.

To build a PWA you’ll hire a frontend developer working with one of the popular frameworks, such as Vue, Angular, React, or Flutter. Alternatively, you can look at the UI SDKs provided by eCommerce platforms that support headless commerce. After you have a working PWA, you’ll be able to add more interfaces that are relevant to your business niche.

What will you have on the backend? Here are three options you can choose from depending on the specifics of your business and the resources you have:

  • Build a set of custom backend microservices. This option is the closest to the “build it” approach and would be most complex. Hiring software developers that specialize in building eCommerce PWAs can simplify the task.
  • Put together comprehensive 3rd party solutions. This implies that you make a mix of external services and your developers rather focus on integration and building API than creating custom services.
  • Plug Commerce as a Service (CaaS). This option is the closest to the “buy it” approach and would be the fastest but costly. You’ll go with an almost ready-made backend app and a developer that will connect it via API to your custom PWA.

It’s interesting that eCommerce platforms that have provided traditional software solutions for years now rolled out their headless alternatives. They see the future in the CaaS model as a way to keep up with the agility and customization merchants need.

Are Shopify, Magento, or BigCommerce headless eCommerce platforms? Yes. Now they allow your developers to plug in their cloud eCommerce engines, such as Shopify Plus or Magento Commerce, on the backend of custom UI apps. They even offer their own user interface SDKs, such as Magento PWA Studio or Shopify SDKs, to assist you with the frontend development.

The downside of CaaS is that available subscription-based solutions have quite a high price tag. That said, this model removes most of the eCommerce application development work and offloads the maintenance of the back-end systems from retailers. We’ll definitely see more and more retailers implementing headless commerce using a given platform vendor’s APIs.

Where to find freelance eCommerce developers?

It’s not necessary to hire an in-house engineering team to implement headless commerce unless you’re going to become another Amazon. Hiring freelancers for this job is a good option especially if you’re on a budget. However, it may be challenging to find really good and reliable specialists without spending much time on vetting.
