EKM vs Shopify: A 2026 Comparison

If you’ve landed here, you’re probably weighing the move. Maybe the EKM price increase letter just arrived. Maybe you’ve noticed your mobile checkout conversion is quietly hurting you. Maybe a competitor’s site loads faster than yours and you’re starting to suspect why. Maybe you’re just looking ahead and wondering whether the platform you chose five years ago is the right one for where the business is going.

This piece isn’t a feature comparison. It’s a trajectory comparison. Feature comparisons date the moment they’re published — and most of them are wrong by the time you read them anyway. What matters is what each platform is built for, where each one is heading, and how that maps to where your business is heading.

I’ve migrated UK stores from EKM to Shopify across very different scales — from a 500-product industrial supplier to a 24,000-customer fire safety business with full historical order data. The lessons compounded across those engagements. Some of them surprised me. The most useful one was discovering that EKM does at least one thing genuinely better than Shopify, and pretending otherwise would have cost a client’s product approvals on day one of going live.

The Four Structural Reasons People Move From EKM to Shopify

These aren’t taste preferences or marketing complaints. They’re structural — the kind of issue you can’t fix without changing platforms.

1. The Technology Is From Another Era

EKM is built on classic ASP and IIS — server-side technology that was current in the early 2000s. You can see the architecture surface even on EKM’s own marketing pages: their URLs still carry .asp extensions. They’ve layered modern CSS and JavaScript on top, but the engine underneath is twenty years old.

That sounds harsh and it isn’t meant to be. EKM has kept the platform working, kept it stable, kept it adding features within the constraints of its foundations. But the constraints are real:

• No proper Storefront API. Headless commerce — building a custom storefront in Astro, Next.js, or any modern framework while keeping EKM’s catalogue and checkout — is essentially off the table. Shopify’s Storefront API is mature and well-documented. EKM’s isn’t comparable.
• No native AI features. Shopify has added AI-generated product descriptions, AI-driven search relevance, an AI assistant for merchants (Sidekick), AI image search. EKM has none of these as first-party features.
• No native subscription commerce. Recurring orders and subscription products are dominant in 2026 consumer ecommerce. Shopify integrates with Bold, Recharge, and Shopify Subscriptions natively. EKM does not.
• No edge CDN hosting. Shopify runs on a global CDN with sub-100ms response times worldwide. EKM hosts in UK data centres on traditional infrastructure. The page-speed gap is measurable on Core Web Vitals.

None of this means EKM is broken. It means EKM is at the technological boundary of what its architecture can do. Shopify isn’t.

2. The Cost Story Has Inverted

Many UK merchants remember EKM as the cheaper option. That hasn’t been true for a few years.

EKM Complete is £299.75 + VAT per month on the annual plan, or £327 + VAT per month if you bill monthly. That covers turnover up to £300,000 a year. Above that, the surcharge starts: an extra £100 per month for every £100,000 of turnover up to £1 million.

So a merchant doing £500,000 in annual turnover pays £527 per month — £6,324 a year in platform fees. A merchant at £1 million pays £1,027 per month — £12,324 a year.

Shopify, by comparison:

• Shopify Basic — £25/month
• Shopify (the mid tier) — £65/month
• Advanced Shopify — £289/month
• Shopify Plus (enterprise) — from around £2,000/month for serious volume

Shopify’s pricing is flat per tier. You don’t pay more as your turnover grows within the tier — you only pay more when you graduate to the next tier, and that’s a decision driven by feature need (B2B catalogue, multi-store, checkout extensions) rather than a tax on revenue.

3. EKM Taxes Growth

This one is structural enough to warrant its own section. The turnover escalator isn’t just a higher fee — it’s a tax on every pound of new revenue.

For a merchant whose revenue is climbing — which is exactly the kind of merchant who should be reinvesting in the business rather than paying more to their platform — this becomes the structural exit reason before “dated tech” even bites. The platform you’re growing into is becoming more expensive because you’re growing.

4. The Growth Ceiling Is Real

EKM has no Plus tier, no enterprise option, no headless capability, no checkout extension framework. When a merchant grows past £1 million in turnover, the bill keeps climbing on the same plan that wasn’t built for that scale of operation.

Shopify Basic → Shopify → Advanced → Plus is a genuine architectural progression. Each tier unlocks meaningful new capability: international markets, B2B catalogue, custom checkout, advanced reporting, dedicated infrastructure. EKM’s escalator just charges you more for the same product.

For a merchant whose business is on a growth trajectory, this is the long-term issue. You’re not just paying more — you’re paying more for something that won’t fit you in three years.

What EKM Does Genuinely Better Than Shopify

Here’s the part most comparison articles skip, because it complicates the pitch. I’m going to do the opposite and lead with it, because any “leave EKM” piece that doesn’t name what gets given up is dishonest — and dishonest doesn’t convert.

There are at least six things EKM does better than Shopify out of the box. One of them caught me out on a real migration, and the lesson is worth telling because it’s the kind of detail that doesn’t appear in any feature comparison.

The Migration That Exposed the Unit Pricing Problem

I migrated a UK fire safety business from EKM to Shopify in March 2026. The data transfer went cleanly. The new site went live. Then Google Merchant Centre rejected forty-five of their products.

The reason: EKM had been sending unit pricing to Merchant Centre natively. Unit pricing — the price per kilogram, per litre, per metre — is a UK and EU compliance requirement for many product categories. Cleaning products. Food. Building materials. Anything sold by quantity where consumers need to compare like-for-like across sellers. The feed has to declare it, and Merchant Centre disapproves products that don’t.

EKM had been quietly handling this for years. Shopify is Canadian — UK and EU compliance isn’t a default behaviour. The unit-pricing requirement is the merchant’s problem, and the only way to solve it is custom feed work, an app subscription, or a hand-built Google Sheet feed.

I rebuilt the Merchant Centre feed manually as a hand-managed Google Sheet feed. The forty-five disapproved products came back. But the lesson stuck: EKM had been doing something genuinely useful that the merchant didn’t even know was happening, and the migration exposed it as a real cost of leaving.

This is the kind of thing you only find by doing the work.

The Six EKM Strengths Worth Naming

The meta-point is more important than any individual item. For a small UK merchant doing under £200,000 in turnover with no growth pressure, EKM may genuinely be the cheaper, simpler answer once the Shopify app stack is honestly costed. The “Shopify is cheaper” argument breaks at the low end. It only wins at scale.

That’s not a footnote. It’s the question every merchant should actually ask themselves.

When EKM Is Still the Right Answer

I would not migrate a merchant to Shopify if any of the following are true:

• Turnover under £200,000 a year and stable. The EKM bundled-features cost advantage is real at this scale.
• No growth pressure or expansion plan. If the business is at the size it wants to be, the trajectory argument doesn’t apply.
• Owner is non-technical and doesn’t want to be. EKM’s visual editor and phone support genuinely lower the operating overhead. Shopify is more capable but requires more skill or more spend on developers.
• Phone support is load-bearing. Some merchants — particularly older businesses, particularly merchants whose previous bad experiences were with platforms that abandoned them to async chat — need to be able to speak to a human. EKM offers that. Shopify Basic does not.
• Current setup converts well and the store is profitable. Don’t fix what isn’t broken. Migration costs time and money, and it should be in service of removing a real constraint, not chasing a marketing pitch.

If you’re in any of those positions, my honest advice is to stay where you are. The migration story isn’t free, and it isn’t the right answer for everyone.

When the Trade Is Worth Making

I would migrate a merchant if any of the following are true:

• Turnover is climbing and the surcharge is biting. Once the EKM bill is materially higher than what Shopify Advanced would cost, the maths flips and stays flipped.
• The variant problem is real. If your EKM store carries thousands of “products” that are really variants of a few hundred actual things, consolidating them on Shopify produces a cleaner site, cleaner SEO, and a more sensible inventory model. I covered this in detail in why your EKM store has 3,000 products but your Shopify store will have 100.
• Page speed is hurting conversion. Mobile checkout abandonment above 70% and a Core Web Vitals score that won’t move are usually platform issues, not theme issues. Shopify on a modern theme is measurably faster than EKM on anything.
• You’re hitting integration walls. Klaviyo flows, Recharge subscriptions, modern review apps, AI-driven search relevance, headless storefronts, sophisticated loyalty programmes, B2B catalogue logic — Shopify has all of these. EKM has limited or no equivalents.
• You’re past £500,000 in turnover and there’s no Plus tier coming. You’re paying enterprise-tier prices on an SMB platform. That doesn’t end well.
• Future-proofing matters more than current functionality. This is the trajectory argument. Where will the business need to be in three years, and which platform gets you there?

The honest version is that most merchants reading this piece are in the second list rather than the first. That’s why they’re reading it. But it matters to name the first list too — because it means when the answer for you is “migrate,” you can trust the reasoning behind it.

What Real Migrations Have Looked Like

Two anchors from work I’ve actually done, at very different scales.

The Lightweight Migration (2024)

A UK industrial supplier with around 500 products and no historical customer data to bring across. The migration ran cleanly because the catalogue was straightforward, the EKM customisations were light, and the SEO redirect map was small enough to verify by hand. The store went live and rankings recovered within days.

This is the shape of migration that fits the £1,490 fixed-price model in my Shopify migration cost guide. Small to medium catalogue, no deep custom code, clean data, sensible URL structure. Most EKM migrations land here.

The Heavyweight Migration (2026)

A UK fire safety business with 24,000 customer records, full historical order data going back years, EKM checkout-and-shipping rules that needed reconfiguring as Shopify-and-Parcelify, custom theme work, and a Merchant Centre integration that exposed the unit-pricing problem I described above.

Five months elapsed. Two weeks of actual build time. The gap was silence — waiting for client decisions and access. This migration didn’t fit the standard fixed-price shape because the variables were too many. It was scoped on its merits, priced accordingly, and delivered.

I wrote about the silence pattern in heavyweight migrations in the main migration guide. It’s the part most agencies don’t tell you.

What It Actually Costs

I’m not going to quote a fixed price in this piece because the honest answer is that most EKM-to-Shopify migrations fall into the fixed-price tier I publish openly in the Shopify migration cost guide — but some don’t, and the ones that don’t need scoping properly rather than squeezing into a bucket.

The variables that actually determine the cost:

• Product count and variant complexity — 500 simple products is a different job to 3,000 EKM products that need consolidating into 100 Shopify products with proper variant structure
• Customer and order history volume — under 1,000 customers is straightforward; 24,000 with full historical orders needs careful CSV restructuring
• Custom EKM code — bespoke modifications, custom mods, store style edits all need to be understood and reimplemented (or deliberately dropped) on Shopify
• Integration scope — Klaviyo flows, Recharge subscriptions, Merchant Centre, third-party ESPs, custom CRM connections — each one is real work
• Theme work — template-fit vs. partial custom vs. full custom design
• Post-launch support — the first two weeks after a migration are when issues surface; budgeting for them properly is the difference between a clean handover and three months of firefighting

If your store fits the standard shape (under 2,000 products, under 5,000 customer records, light or no custom code), the published migration cost guide is accurate. If it doesn’t, get in touch and I’ll scope it honestly before I quote a number.

The Honest Bottom Line

EKM is a real ecommerce platform built by a real UK company with real strengths. It is not a bad platform. For some merchants — small, stable, technically light, growth-relaxed — it is genuinely the better choice. I would not move those merchants if they asked me to.

For most others, the structural case is clear: the technology is dated, the pricing inverts at scale, the growth tax compounds, the ceiling is low, and the migration cost only grows the longer you wait.

The question isn’t whether Shopify is “better.” Both platforms can run a UK ecommerce business. The question is where your business is going, and which platform is built for that trajectory.

If the answer is “I’m staying small and that’s the plan,” EKM is fine. If the answer is “I’m growing, the variant count is climbing, the integration list is getting longer, and I’m starting to look at headless storefronts and AI features and international expansion,” the platform that gets you there is Shopify.

If you’d like me to walk through your specific case, get in touch. I’ll be honest about whether the migration is right for you — including, sometimes, recommending you stay on EKM. Doing the wrong migration for the wrong reasons is worse than not migrating at all.
