About By Association Only


We are an award-winning eCommerce agency based in Cambridge, UK. Over the last 6 years we've launched websites for large multi-national brands like The European Tour, Cambridge Satchel Company and Tchibo Coffee, and smaller startups such as Shopskin & Paul Valentine.

As certified Shopify experts we deliver the design and development of dynamic e-commerce websites on this friendly platform that’s fully scalable. Our Shopify builds are completely bespoke and tailored to your specific requirements, with a huge amount of emphasis on making the site as editable as possible for the client.

We build using the latest industry standards, which may seem like gibberish but actually makes a huge impact on every aspect of how your site performs. From usability to SEO and accessibility, clean syntax and structured code is at the heart of what we do.

We carefully plan all of our websites from inception to be as dynamic and responsive as possible. With us, it’s not an afterthought, or something that’s bolted on when the site is built. It’s considered through initial design concepts for maximum potential.

Our motto is ‘the best design is the simplest one that works‘ and that resonates throughout every project. Detailed R&D into specific sectors is carried out to ensure that everything we do is as tailored to it’s users as possible. Nothing is left unscrutinised.


• Never outsource work: You know that every pixel is designed in-house, as is every line of code. We make sure that designers and developers discuss their work for the best results.

• Don't cap design revisions: We're so confident in our design abilities that we don't feel the need to cap the amount of rounds of revisions that you can make during the design phase.

• Go the extra mile: We've never spent a penny on marketing because we haven't needed to. Our work speaks for itself.

• Make it editable: We spend a great deal of time making sure that every aspect of our websites is editable from within the Shopify admin panel.

• Full Access: Throughout your project you can be in direct contact with our founders, the designers and the developers so that nothing is lost in translation. No hiding behind project managers.

• Be Transparent: We'll never add extra costs onto a project unless the goal posts change dramatically. We have no hidden costs. We don't charge projects by the hour, we cost to get the project done, and done right.

• Constant communication (if you want it): We keep you informed throughout the entire process so that you know exactly what we're spending our time on.

• Deliver on time: We've never delivered a project late. If we say a time, we'll stick to it even if it means working evenings and weekends.

• Know your s**t: we employ full-stack developers as well as front-end developers so that we can achieve the most complex integrations possible on Shopify.

• No themes: We NEVER start a build by using an existing theme. Every line of code is written in-house which means no redundant code.

• Win awards: Ok, this ones more for us than you but it does mean that you'll get the highest standard of website. We are the only agency in the world to win two Awwwards 'Site of the day' awards on Shopify.

CARAT* London

We have recently moved our website from Magento to Shopify plus, with the design and development being carried out by the By Association Only team and we could not be happier. The full process was a true collaboration throughout with James, Evan and the entire team listening, understanding and actioning any idea or request we had as well as providing their own ideas an input to help create a new, great looking and user friendly website for our brand. The knowledge and understanding of the shopify platform that the BAO team had, as well as the support and guidance they provided us throughout the development was invaluable and made it a real pleasure to work with them on this project.

Link Nutrition

It has been a pleasure working with BAO from start to finish and we continue to work with them now that our initial bespoke Shopify website design build, brand creation and packaging design is complete.

They simply made our lives easier and created a striking brand that we have had hugely positive feedback on. They worked iteratively with us until we were 100% satisfied with our brand and always seemed happy to make little tweaks and come up with new concepts whilst providing us with their professional opinion.

They reinforced our brand with a stunning looking website with plenty of dynamism and considered UX. Unlike prior experiences developing websites, the first version delivered was bug free on both mobile and desktop. Their communication throughout the project was great and at no point did I feel they would miss any deadlines, which was ultimately met with time to spare.

We had never used Shopify before and they were more than happy to support us and answer any questions we had, regardless of how simple or technical they were.

We genuinely felt that BAO cared about us and our brand, and for this reason we would highly recommend them. The quality of their work speaks for itself.

Giulio Fashion

We approached BAO to re-design our Shopify store to create a more bespoke website, fitting of our company branding. The team were extremely helpful from the start of the process and delivered on all aspects of design and functionality. The final product is slick and modern but ultimately it captures the essence of what Giulio is all about.


By Association Only, is one of the best agencies I have worked with. Our one-time project has turned into a long-term partnership, as the team has become my agency of choice.

BAO captured the essence of the ShopSkin brand and brought it to life. Winning us a number of design/development awards along the way. Not only focusing on the design aspect but giving great advice on how to increase click-through rates and conversions. The team is filled with experts in the field of e-commerce, design, and development.

It has been an honor to work with the team. I cannot understate enough how important it is to have a quality agency, like BAO work on your e-commerce site. The choice of selecting them as our design agency saved us countless time and money.

Harris & Jones

We spoke to quite a few agencies before deciding upon who to work with and BAO just seemed to understand exactly what we required from the start. They just seemed a level above other agencies. We were coming from an unreliable, expensive Magento site with lots of limitations in important areas such as data analytics, shipping, social media integration. The Shopify platforms immense scope and power resolved all our frustrations and with BAO’s design & development skills gave us the opportunity to make it easy for our customers to navigate, select, customise & buy products. Within this project were complex variant requirements for each product and we knew this would be a key factor to the success of the site going forward. BAO developed & proposed a solution which was not only visually appealing front end but easy to update & manage as owners. We look at BAO not only as our website agency of choice but as an ecommerce partner who can help & guide us as we grow our business.

Real pleasure working with the skilled, conscientious & competent team at BAO.

My Name Label

One word - Legends. This project was not straight forward and they embraced the challenge with enormous professionalism. My Name Label has been an e-commerce site since 2002 and although the existing website was not that old it was in need of modernization in terms of design, functionality and particularly to ensure leading edge SEO. Added to this was the need for a custom application that had to interface with Shopify.
BAO are brilliant communicators and collaborators which meant that we felt involved and were able to consult throughout the development process. Not once did we have that feeling of being left in the dark. They are great problem solvers as well - if we hit a hurdle they found a way over it. Clear (and agreed) objectives and project plan which was adhered to and no budget creep. And distance was no barrier either - in fact the UK/Australia time difference made the process even more productive. Would I use them again - absolutely. Thank you BAO.


The By Association Only team went over and above to ensure that our project was executed in line with our desired timeline, designed immaculately + was a perfect representation of our brand. They continue to provide support and offer helpful advice and we've already embarked on our next project with them. I couldn't recommend them highly enough


Hands down, the best agency experience we have had.

We shortlisted a number of agencies to work with for our project - a new Ecommerce website for one of our brands, Lighthouse. We quickly identified 'By Association Only' as the one we wanted to work with - and we made the right choice! They excelled in every area of this project.

You don't often start with this point, but the project management and communication all the way though was friendly, positive and thoroughly professional. It gave us lots of confidence and built a lot of trust that we could rely on By Association Only to deliver to end result we were looking for.

We had quite a well developed idea of what we were looking for, but By Association Only were able to listen and quickly understand our requirements, and produce a design concept that exceeded our expectations. As with all these projects, the back and forth and collaboration help to produce the best possible end result, and By Association Only were a dream to work with. Always understanding our feedback, and always coming back with a better solution.

We identified a number of priorities at the start of the project, particularly the mobile experience - and it was really pleasing to work with an agency that delivers. Finally, post-launch they don't disappear but stay live on the site to iron out any little bugs or tweaks that are needed.

There are a lot of agencies that market themselves very well but under deliver. It's the opposite with these guys - I highly recommend you consider them for you next project.

The Cambridge Satchel Company UK Store

We have recently migrated from Demandware to Shopify Plus and selected BAO as our design and integration agency. BAO impressed us from the start with their speedy grasp of our business needs. The team at BAO have a very thorough knowledge of Shopify and Shopify Plus. They were under pressure to deliver 4 new Shopify stores for us within a very short time period. Not only did they achieve this but actually had the sites ready a day before the go live date. Start to finish the project took less than 3 months. The project itself was quite complex however BAO developed a great solution for us. During the project we faced a number of business challenges, BAO went above and beyond to help our business come up with workable solutions We are delighted with the design of the sites and I would not hesitate to recommend BAO. Post go live, I look forward to continuing to work with BAO as an extension of our online team for further development needs and support.


Amazing and super efficient team. We had the pleasure to work with them as a shopify Plus store. If you are looking for an agency to get your new site going, don't hesitate to contact them. Highly recommended!


BAO Agency was responsible for designing new webfront of our Shopify Plus store We were very pleased with the results of this co-operation. The design works went very fast and we were very satisfied with the quality of design. We gained a lot of acclaim for the new design of our webservice – our customers appraise it as really beautiful and functional now. Our opinion about BAO in one sentence- they know what they are doing and are good at it. We are confident that BAO is the best choice for any Shopify store owner.

We can honestly describe working with BAO as one of our best decisions while migrating to Shopify Plus. BAOs job was to adjust the design of our old web design to Shopify. It was a difficult task with countles problems to solve along the way and a very little time available. They managed to do it faster than sheduled. After finishing the project we still co-operate and BAO developers constantly improve our webfront. They are really committed, helpful and work fast. The biggest value of working with them though is the knowledge that BAO is a trustworthy partner. They will not ( and we an example of that) accept an assigment they know they wouldn’t be able to deliver on time or satisfying quality. We sincerly recomend BAO as we are happy to work with them.

Sneaker LAB SA Store

By Association Only were very professional, stuck to deadlines and were very easy to deal with.
I would highly recommend them.


BAO were professional, their communication was brilliant and they got many things right from the very beginning making our job much easier.
We were very impressed with how they took our brand and translated it into a great looking website. The functionality of the website is up to the highest standard and the support they provide far exceeded our expectations. Will definitely use them again for future projects.


Well what can I say it was a perfect match!

The whole team was absolutely fantastic from start to finish. They held our hands all the way through the process, the end product was exactly what we wanted.

It was all positive vibes from the start, they never said "No it cannot be done" it was always "sure, no problem!"

We now have a very clean and responsive site thanks to you guys.

BAO are hands down the best in the business!

Couldnt thank you guys enough.


Kala Sundial

By Association Only (BAO) was recommended to me by a trusted friend. Let me start with the following, James and Josh at BAO are absolute legends. Their experience, speed and friendly approach was mind blowing. In over 10+ years being exposed to web services I have never felt that my money was better spend than with BAO . The team just knows their stuff and gets what I was trying to tell them (without being an expert). It was an absolute pleasure to work with BAO and will surely continue to do so. Great work BAO, onwards and upwards. You guys rock!

My Pinnacle Nutrition

James and the guys at BAO have been a genuine pleasure to work with. Being able to regularly talk to the guys, something which is rare these days, made the process not only easy but also thoroughly enjoyable. Throughout the development of our website, the communication from BAO has been second to none. Any alterations, design changes, questions; the guys always followed up near enough immediately, again something which is rare these days!

The quality of the work speaks for itself. Our website has been very well received, and has been a great success! It is a pleasure now knowing someone who we can turn to, who will deliver quality work, in a short time frame.

We look forward to continuing to develop our Shopify website, as well as other projects, with the guys at BAO.


BAO built our site from scratch on a Shopify platform and throughout the process couldn't have been more flexible and helpful. Every member of their staff we've spoken to has been professional and supportive and, above all, patient with us. The site looks great and is working well. I couldn't recommend them more highly. Gavin Aldred, Owner


From initial idea to launch BAO have been there every step of the way. Together we have created a beautiful well thought out and designed website that ticks all our boxes.

Paul Valentine

Can't recommend them enough! Our conversation rate and sales went through the roof after we launched our new bespoke Shopify site! Every dollar we invested was worth it, and we enjoyed working together with such skilled, creative and passionated people!

5 Stars for Creativity and Design Thinking
5 Stars for delivering very fast and on time
5 Stars for adaptability, since we asked for a lot of additional features during development face.

Busy Panda

What to say except that the team at BAO was amazing from start to finish.
They finished work before due date and on budget.
They came up with some design adjustments which made our website much more user friendly.
They are excellent communicators who are always available t answer all your questions.
Look no further!


I was 100% pleased with the phenomenal service I received from James Trippett and his team at By Association Only. I was initially nervous about hiring them as I had to prior "association" with them and was going purely on Shopify reviews, I was even more nervous when I agreed to pay upfront in full for a slight discount. I am pleased to say they over delivered and I plan to use them for my future projects. I would highly recommend them.


Really great to work with By Association Only! They are very professional and fast. They not only do very good quality job, they even come with their own innovative ideas to improve my business. Looking forward to work for other projects with the company.

Yasemin Özeri

I am so happy to work with the expert. He was so fast and helpful, the communication was so fast and easy.


Completed the work on budget and within the timeframe given. Excellent communicators, highly talented and super professional.

Tchibo Coffee Online Shop

After talking with over a dozen agencies about our project, BAO stood out amongst the crowd. They really sought to understand our business objectives to make the most informed decision on platform choice with us. They work with honesty and transparency and remained in constant communication with us throughout the project. We are all thrilled at Tchibo Coffee Service with the website that BAO designed and built for us and hope to work with them on future projects. We'd thoroughly recommend them to any business that wants to work with a talented, professional and forward thinking agency.

Ollie & His Superpowers

The team at By Association Only (BAO) made the experience of getting my website and shop produced and launched as easy as it could be. They immediately got the concept I was looking for on the design of the website. They embraced the ethos of my company of transposed it onto my webpage. They walked me through every step of how to manage my products on the shop with advice, hints and contacts about how best to display my products to maximise their sales potential. And they have continued to help me since the launch of my website. I would highly recommend BAO to anyone who is looking for an great webpage and who wants to work with nice people.

Suffolk Latch Company

In 20 years time we will all look back at the early days of ecommerce and realise that those days really were the “Wild West”. With almost every trade and service I can think of today there is, quite rightly, a high level of regulation to guarantee performance and safety. With the world of ecommerce we are certainly a long way from that goal.

I came across By Association Only (BAO) after a great deal of research and I must say after being burnt the first time round by a rouge developer I was a little skeptical. But from the outset BAO was absolutely on the case, every stage of the process was expertly executed, they were happy to learn about my business and build the site to perfectly match my needs. With their expert knowledge there were able to suggest and implement functionality that I never thought was possible.

An absolutely top notch web store is never going to be a cheap undertaking, but what I would say is that if you are committed to your product and are serious about building a successful business then you would be hard pushed to find a better developer. With so many sharks out there your best defense is a great recommendation. BAO will deliver you a great site.

The Cult & Classic

A fantastically talented team of creative and technical minds who go above and beyond to create the perfect website. They have made the whole process of my move from Magento to Shopify as seamless as possible ensuring that all content was transferred as efficiently and quickly as possible and were quick to assist with any queries I had. I would always recommend By Association Only to anyone looking for a team to design and develop their Shopify website as I've always had a professional and friendly experience with them.

Cambridge Coral Tech

The team at BAO helped us to start trading online and we've never looked back.

They were always available to discuss our ideas and then implemented perfectly beyond our expectations. The work was even delivered two weeks early.

Couldn't speak of them highly enough and would certainly recommend their services.


BAO understood exactly what we were looking for and delivered an engaging, content driven site. They also helped us to create packaging for our drinks, which looked great. The work was delivered on time and on budget. Would highly recommend.

Kurly Klips

You know that warm feeling you get when you think you've stumbled on the perfect contractor? After looking through their official site's portfolio, I just knew I had finally found the right people to re-brand/re-design my online presence (website, social media, newsletter, etc). And what can I say? My instincts are amazing. After one conversation, BAO instantly understood my brand and designed something incredible. Thanks to them, I have a unique, gorgeous, and functional web presence that I am truly proud of. Not to mention the team is also highly professional and responds fairly quickly to requests. I am a very happy client and will use them again for future work.

Jennifer Torosian

Evan Richards from By Association Only was very professional and knowledgeable. I was interested in working with him after seeing some of his previous work. While developing my website, he paid close attention to all of the aspects of design I was looking for, and seamlessly incorporated all functions needed for the site. I would recommend By Association Only because of the standard of work quality and work ethic. Evan was also very quick to offer advice and recommendations that were needed to create a better performing site. By Association Only is very detailed oriented and we are very happy customers.
