Super fast · Clean UX · Bespoke builds

Magento 2 and WordPress specialists.

We build stores and websites that are super fast on a phone and clean to use. Every build gets a performance budget at design stage and passes Core Web Vitals on mobile before it launches, and every interface is designed in-house with one clear next step on each page. All of it bespoke, built to the standard our team learned on globally recognised brands, connected to your PIM, ERP and CRM, and yours outright.

What we do

Magento 2 and WordPress first, then everything built around them.

Most of our engineering time goes into Magento 2 - security upgrades for stores stuck on unsupported versions, Hyvä frontend migrations and bespoke replatforms. Around that we build the custom CRMs, internal tools and integrations that join your systems together, and bespoke WordPress and WooCommerce sites you own outright when they’re done.

How we build

Eight things true of every project.

From a £1,450 rescue to a six-figure replatform, the same standard applies.

01

Super fast by default

A performance budget is set before design starts and held through the build. Server-rendered pages, properly sized images and fonts, and no third-party script without a reason. Every site passes Core Web Vitals on mobile before launch, and you get the numbers.

02

Clean, obvious UX

One job per page and one clear next step. No pop-ups, carousels or chat widgets competing for attention unless they earn their place. Researched, wireframed and designed in-house by the team that builds it.

03

Designed to convert

A site that looks good and sells nothing is a failed project. We design the journey first: what someone is trying to do, and what is in their way. Then we keep measuring it after launch.

04

Specialists, not generalists

Magento 2 and WordPress, done properly. Our team has been building and managing Magento 2 stores since the platform launched, and WordPress for longer than that.

05

Bespoke, never templated

Every build is designed from your business outwards. No themes bought off a marketplace, no page-builder sprawl, no template you share with four thousand other companies.

06

Built to brand standard

Our team has built and maintained sites for globally recognised brands. Code review, staging, performance budgets and accessibility sign-off run on every project here, whatever the size.

07

Built to the highest standards

Coding standards, version control, staged releases and WCAG 2.2 AA accessibility as a pass condition. Nothing goes live from a laptop.

08

PIM, ERP and CRM, connected

Your catalogue, stock, customers and orders should agree with each other. We integrate with Akeneo, Pimcore, HubSpot, Salesforce and Dynamics, or the bespoke system we build you.

FAQs

Our most commonly asked questions.

Some quick answers to some of the most common questions our team gets asked on a regular basis.

Ace21 Industries is a UK digital agency specialising in Magento 2 - security upgrades, Hyvä frontend migrations and replatforms - alongside bespoke CRMs and internal tools, mobile apps, and WordPress and WooCommerce builds. We work with clients across the UK, Europe and North America.
Yes. Magento and Adobe Commerce 2.4.5 and 2.4.6 stopped receiving security patches on 11 August 2026, so anything still on those versions is running unpatched. We move unsupported stores onto a supported release at a fixed price and fixed scope. If you're not sure which version you're on, start with the health and upgrade audit.
A five-day technical audit of your Magento 2 store: version support status, security exposure, real Core Web Vitals, extension compatibility and a costed upgrade plan. The fee is credited in full against your build if you go ahead.
Hyvä is a high-performance frontend that replaces Magento 2's default Luma theme. It ships far less JavaScript, which is why Hyvä stores routinely land mobile Core Web Vitals inside Google's thresholds - something Luma is very hard to fix by tuning alone.
Yes. We offer a full setup, design and build service to take your business from ideas on paper to selling online.
Yes. We build bespoke CRMs, internal tools and data dashboards - usually for businesses running something critical on a spreadsheet three people are afraid to touch, or paying for an off-the-shelf platform that answers every question except the two that matter.
Yes - iOS, Android and cross-platform, built by a UK team you can talk to directly. We'll also tell you in the first call if a fast mobile website would serve you better, because most businesses that ask for an app need one of those instead.
Yes, outright. No rented websites and no monthly plan you can never leave with anything to show for it. The same applies to custom software - you own the code. Care plans are available afterwards as support contracts rather than instalment plans.
Yes. Our rescue and takeover is a fixed five-day job: security lockdown, tested backups, updates, a speed pass and a documented handover, with every login back in your name. There's no ongoing commitment afterwards.
Yes. We have offices in the UK and Ireland and work with clients across the UK, Europe and North America.

A straightforward process, start to scale.

01

Audit & discovery

We audit the site, the store and the systems behind them, and agree what success actually looks like before anyone designs anything.

02

UX and design

Journeys, wireframes and the finished interface, designed in-house around how your customers actually buy.

03

Build & integrate

Built bespoke to coding standards, on staging, with your PIM, ERP and CRM connected and tested before launch.

04

Measure & grow

Performance, accessibility and conversion measured after launch, then reviewed with you rather than left in a dashboard.

Client story
We came to Ace21 with a website in a bad way, and they rescued it completely. What we have now is a bespoke WordPress site built around how our business actually works — and it's fast. Their expertise was clear throughout, and communication was excellent from start to finish.
