Shopify Plus Agency

WBD is a small e-commerce agency in Oxford. We design and build Shopify and Shopify Plus stores for independent brands — and our first advice, to most brands who ask about Plus, is that they don't need it. Not the tier, and not an agency to install it. That advice comes free, and it's where every good Plus conversation we've had has started.

The pattern arrives weekly. A brand grows, the site starts to strain, someone reads that the serious operators are all on Plus, and the upgrade becomes shorthand for we've made it — the tier treated as a badge rather than a decision. In our reading, three out of four brands who arrive asking about Plus are describing a craft problem, an app-bill problem or an operational-complexity problem, dressed up as a platform-tier problem. This page is about telling those apart — and about what an agency is actually for if you land on the side that genuinely needs one.

If you want the longer argument about staying put, we wrote When (Not) to Leave Shopify; the headless version of the same argument lives in Shopify Headless Commerce. This page is the tier-specific conversation; the umbrella view of the design work itself is at E-Commerce Website Design Agency.

We've run stores, not just built them. Always Riding — the D2C cycling boutique we founded in 2008 and sold in 2018 — taught us the operator's side of the ledger. Then three years as consultant e-commerce directors for Above Category in Sausalito put us deep inside Shopify itself: the theme code, the app marketplace, and the bill at the end of each month. That's the seat this page is written from, and it's why the app bill features so heavily in what follows.

Plus isn't a different product. It's the same Shopify with the ceiling raised and a handful of genuinely useful levers unlocked. The ones that matter, in our experience:

A checkout you can actually change. On standard Shopify the checkout is largely Shopify's. On Plus you get real control over the flow and the logic inside it, through checkout extensibility — for most brands, the single biggest reason to move. (The old Scripts route to the same thing stopped running on 30 June 2026; anyone still quoting Scripts is working from an old map.)

Custom logic without the apps. Shopify Functions for the rules standard plans force you to fake with a subscription — and the payment and delivery customisations that run at checkout are Plus-only. B2B sits alongside: it's on every plan now, capped at three active catalogues, and Plus lifts the cap and lets you assign catalogues to individual company locations.

Headroom. Higher API limits, more staff accounts, and multiple expansion stores under one plan — which earn their keep when you're running distinct regions or brands, or when a team of ten is working the store at once.

Notice how many of those replace an app you're already paying for. That's the part worth doing the maths on.

The trigger is rarely revenue on its own, though a figure has to live somewhere: at the time of writing, Plus runs $2,300 a month on a three-year term, $2,500 on a one-year one, shifting to a small percentage of sales for the very largest stores. The better signal is complexity. Plus becomes a sensible move when how you sell has outgrown what standard Shopify and a well-built custom theme can carry — and when the apps you've stacked to paper over the gap cost more, every month, than the tier would.

We've seen mature stores paying four-figure monthly app totals before anyone's totted up the receipts: email, reviews, loyalty, subscriptions, a wholesale portal, a tax engine, search — each £30 to £150 a month, integrating with each other through yet more apps. When Plus's built-ins absorb enough of that stack, and you genuinely need the checkout control or the real B2B, the sum starts to point one way. If it doesn't, you're buying a bigger engine for a car that runs fine.

What a buyer is actually weighing, plainly. (The fuller plan-by-plan version, Basic through Plus with the numbers attached, is at Shopify vs Shopify Plus.)

The honest thing about that last row: most brands losing sleep over their site belong in the left column. A custom theme, a fresh design pass, a copy rewrite — the templated feeling is a craft problem, and it's fixable without touching your plan at all.

If you do move, the agency's job is not to click upgrade and send an invoice. A partner worth paying should own:

The decision itself — including the willingness to talk you out of Plus when the maths doesn't hold. We'd rather lose that project than sell you a tier you don't need.

The migration — store, data, customer accounts and SEO carried across without breaking the trail, and the app stack reconfigured against the built-ins that now replace it. The full procedure, and what it loses when it's rushed, has its own chapter: Shopify Migration Agency.

The checkout and the custom logic — usually the actual reason for the upgrade, built properly rather than left at defaults.

The design and the words, not just the plumbing. How a site reads and looks and moves is the work, and a Plus store that behaves better but still looks templated has fixed the wrong problem. That's the shape of how we work: listen, design, deliver, then stay in the mix — because a store on Plus is more moving parts, not fewer, and someone needs to keep understanding how it's built.

Moving up to Plus is reconfiguration rather than relocation — the store, the data and the URLs stay where they are, and the work is in the checkout, the custom logic and retiring the apps the tier now replaces. It's a project, but it's the mildest thing anyone calls a migration.

The serious version — arriving on Shopify from Magento, WooCommerce or BigCommerce, with a decade of rankings and internal links to carry — is a different animal, and it has its own chapter: Shopify Migration Agency, with the Magento specifics at Magento to Shopify Migration. Read those before you sign anything with anyone, ours included.
