Ecommerce Agency for London Brands

An Ecommerce Agency for London Brands, an Hour From the City

Why Matters is an ecommerce agency for London brands run from Brighton, about an hour from London Victoria by train. We design, build and grow Shopify stores for founder led brands across the UK, and most of the work happens on a weekly call, by email and in a shared project board, so where a team sits has never decided how a project goes. When a kick off, a workshop or a launch is better done in person, we come to London.

We are a Shopify Select partner with Verified Skills across development and marketing, and a Klaviyo, Recharge, Awin, Meta and TikTok partner. Our founder, Ayo, has over 20 years in ecommerce and digital marketing.

Our prices are published on our Shopify packages page, so you can compare us with any London ecommerce agency before you call.

Shopify Developers for London Brands

Our Shopify developers build custom themes, apps and integrations for brands in London and beyond, and every development project carries a 3 month guarantee. The work ranges from theme customisations and speed fixes to Shopify Plus checkout, B2B and connections to your warehouse or ERP. A trade portal we built for a fizzy drinks client cut the time spent keying trade orders from five hours a week to 30 minutes a month.

We work in your store through a collaborator account, which you can remove at any time, and we reply within 24 hours. One off tasks are charged at our ad hoc rate, and regular work sits on a retainer from £650 a month plus VAT, billed one month in arrears with no long contract.

Ecommerce Website Development and Design for London Brands

Ecommerce website development and design for a London brand starts with the pages where people decide: the homepage, your main collections and the product page. We design on Shopify every day, and the developers who build what we design sit on the same team, so a design never has to be simplified in the handover.

A template customisation usually takes one to three weeks and a custom theme four to eight, with a dedicated project manager from brief to launch. When we helped Halo Coffee with its rebrand and relaunch, Halo invested in specialist product photography and worked with the creative agency Uncommon, and its conversion rate rose from 0.5% to 3% after the relaunched site went live.

Our Shopify designers page shows how the process runs.

A UX Agency for London Shopify Brands

As a UX agency for London Shopify brands, we start from how people actually shop on your store rather than how a design looks in a mockup. Of 265 stores we audited, the median conversion rate was 1.7%, and most of the gap between the best stores and the rest sat in the same places: slow pages, product pages that leave questions unanswered, and checkouts that hide delivery costs until the end.

We research with session recordings, surveys and your support inbox, redesign the pages that matter, then test the changes. When we improve product pages, conversion rate typically rises by about 2 percentage points for badly designed pages and by 0.5 to 1 point for average to well designed ones.

Our CRO agency page explains the method.

Shopify Experts for Growth After Launch

A London brand looking for Shopify experts usually needs more than a build, so we also run the marketing that follows: SEO, Klaviyo email and SMS, Google and Meta ads, TikTok Shop, affiliate programmes through Awin and subscriptions through Recharge.

The numbers show why it pays to run them from one team. Across 198 client stores, email is a median 30% of revenue, and when we audit a new client's Google Ads account, an average of 30% of spend is wasted. We report on Shopify sales rather than platform claims, and any ad account we set up belongs to you.

Our ecommerce growth agency page sets out how the channels fit together.

How We Work With London Teams

Most of our work with London teams happens on a weekly call, by email and in a shared project board, with no ticket system and no set development days: you raise what you need by email, phone or on the call, and we reply within 24 hours. Discovery produces a written scope and a price before any work starts.

Retainer clients are billed one month in arrears, are not tied into long contracts and can leave at any time, and everything we build, from ad accounts to theme code, stays in accounts your business owns. For a kick off workshop, a launch or a quarterly review, we can meet at your office in London or host you in Brighton.

If you already have an agency, we can take over an existing store without a rebuild; our Shopify support page explains how.

Why Choose a Brighton Agency Over a London One?

Choosing an ecommerce agency outside London does not mean choosing a smaller one; it usually means paying for the work rather than the postcode. Our prices are published, so you can compare them with any London ecommerce agency before a call: Shopify retainers start from £650 a month plus VAT, a bespoke Shopify website from £650 and digital strategy from £450.

What you get for it is a team that works only on Shopify, Shopify Select partner status with Verified Skills across development and marketing, and the Klaviyo, Recharge, Awin, Meta and TikTok partnerships a growing store needs.

If you want to see the work first, our portfolio and the video reviews on our homepage are the place to start.

Frequently Asked Questions

Do you have an office in London?

No. We are based in Brighton, about an hour from London Victoria by train, and we work with Shopify brands across the UK. Most of our client contact is by video call and email, and we come to London for kick off meetings, workshops and launches when they are better done in person.

Can you work with a team based in London?

Yes. The way we work, with a weekly call, email and a shared project board, is the same wherever a team sits, and we reply to requests within 24 hours. Distance has never decided how a project goes.

How much does a Shopify agency cost in London?

Few London agencies publish their prices, and the ones that do vary widely. Ours are on our Shopify packages page: retainers start from £650 a month plus VAT, billed one month in arrears with no long contract, and we quote a fixed price for a build after a discovery call.

How long does a Shopify website take to build?

A template customisation usually takes one to three weeks and a custom theme design and build four to eight weeks, as long as the scope is clear and feedback comes back promptly. Migrations from another platform normally take less than two weeks, depending on how many products need moving.

Can you take over a store another agency built?

Yes. We take over existing Shopify stores through collaborator access, review the theme, apps and tracking, and fix what is holding sales back before suggesting anything bigger. Any ad account we set up belongs to you, and so does the code.

Are you a Shopify Plus agency?

We are a Shopify Select partner with Verified Skills across development and marketing, and we build, migrate and support Shopify Plus stores, including checkout extensibility and B2B. We will also tell you when Shopify Advanced is enough.

How do I get started?

Email info@whymatters.co.uk or call 01273 569264. We will arrange a call to understand your store and give you an honest view of whether we are the right fit.
