Do you offer headless builds?

Our team is well versed in headless technologies. This enables us to achieve even more for clients who are looking to move into the headless space and create truly exceptional experiences.

Can you help with branding or digital marketing?

No, our team knows their strengths, and thus we only provide the services we know we can deliver on with exceptionally high quality. Having said that, we can connect you with a number of incredible partners who are well positioned to assist you with things like branding, email marketing, copy writing, and more.

Do you only work on Shopify?

Whilst our team has expertise in a range of areas, our core focus is Shopify, thus we find our clients get the most out of our team when utilising Shopify.

What does the process look like?

Like all good things, we start by getting to know you. We find it is essential to make sure our team is the right fit for your brand. Once we have established we are a great fit and have gotten to know you, the team and the brand we will make a start.

Depending on the direction you choose to head (themed, hybrid, completely custom), the process will differ slightly. However, more a less they will all share some arrangement of the following stages:

  • Discovery session

Getting to know your brand

Brand Deep Dive

Before we dive into the nitty-gritty, it's essential to immerse ourselves in your brand. We'll get to know your brand identity, values, target audience, and long-term goals. By understanding what makes your brand tick, we can ensure that the Shopify store we design genuinely reflects and amplifies your brand ethos.

Gaining an understanding

Scoping & Strategy

With a clear grip on your brand, we'll sit down with you to define the project's scope. This phase involves discussing the desired features, integrations, and functionalities you're after. We'll also have a yarn about any potential challenges and brainstorm the best approaches to achieve your goals.

Design + Review

Design Phase

Based on our chats, our talented design team will begin crafting mockups and wireframes. We prioritise user experience and aesthetics, ensuring that every design decision enhances usability while resonating with your brand's look and feel. Once the initial designs are ready, we'll touch base with you for feedback and tweaks.

Shopify Theme DEvelopment


After locking in the design, our developers roll up their sleeves and get cracking, bringing the vision to life. We focus on writing clean, optimised, and robust code. Whether it's integrating advanced functionalities, third-party APIs, or custom features, we ensure your Shopify store is a smooth operator.

Before going live

Testing & Quality Assurance

Before going live, we go hard on testing across various devices, browsers, and screen sizes to ensure top-notch compatibility and performance. Any bugs or glitches are sorted straight away. We also reckon it's a good idea for you to jump in during this phase to have a squiz and ensure the site's up to scratch.

Launch & Go Live

Launch & Go-Live

With testing sorted, it's time to unveil your store to the world. We'll guide you through the launch, ensuring everything's spot-on for a smooth kickoff.

Seamless & enjoyable

I've worked with devs for my entire career and have never had such an easy, seamless and enjoyable experience. Kynon and Kurt delivered a beautiful website for us, but beyond that and more importantly to me, they integrated with our team in meaningful way with open, honest and fast communication. I'd work with them again in heartbeat.
