Shopify Plus & Headless Commerce in Dublin
Markets, Functions and B2B for Irish brands running three tax regimes and one inventory pool.
Delivered remotely for brands across Dublin and Ireland.
Scale · Dublin
Why Dublin brands come to us for this
- Shopify Markets configured as EU, GB and US with correct tax treatment in each, from one admin and one inventory pool
- OSS-ready EU tax setup so destination VAT is charged and reported before you trip the €10,000 threshold
- Britain built as an export market: commodity codes, country of origin and a delivered-duty-paid shipping option
- B2B on Shopify for the stockists you picked up at Showcase — company accounts, price lists per currency, net terms
- Shopify Functions for destination and age rules on alcohol-adjacent and barware lines, enforced at the cart
An Irish brand hits the complexity ceiling on revenue numbers that would not trouble a store selling in one country. It is not volume that breaks the setup, it is jurisdictions. You are selling into the single market under OSS, into Britain as an export with customs data attached, and into the United States where the tax question is a nexus question and nobody collects duty on a small parcel. Three regimes, one catalogue, one admin — that is what Markets is for and it is why so many Dublin brands need Plus-tier engineering sooner than their turnover suggests.
The most expensive thing we fix locally is a store still treating Britain as if it were an EU country. Since Brexit, a parcel to a GB customer needs commodity codes, country of origin and a customs declaration, and if you have not configured a delivered-duty-paid option the buyer gets asked for money by the courier at the door. Some pay it, some refuse the parcel, and the ones who refuse cost you outbound freight, return freight and a customer who tells people. Configuring GB as its own market with DDP shipping is unglamorous engineering with an immediate return.
Then there is wholesale, which most Irish consumer brands acquire almost by accident. You exhibit at Showcase, you come home with stockists across Ireland, Britain and a few in the States, and within a year the ordering process is a shared inbox and a spreadsheet of agreed prices. Shopify B2B replaces that with company profiles, currency-specific price lists, quantity rules and net terms on the same catalogue and inventory as your DTC store. Headless is a separate conversation, and for most brands at this size the honest answer is no.
Local context
One store, three tax regimes, and the alcohol rules on top
Configuring Markets for an Irish brand is mostly a tax and logistics exercise rather than a design one. The EU market has to charge each destination country's rate once you pass the €10,000 pan-EU threshold, and it has to report cleanly enough that the OSS return is a filing job rather than a forensic one. The GB market needs its own pricing, its own shipping profiles and customs data on every line. The US market needs dollar prices with sensible rounding, a returns answer that does not involve posting a jumper back to Dublin at the buyer's expense, and clarity about where you have sales-tax obligations. On top of that, whiskey accessories and barware brands carry destination rules that vary by country and by state, and those belong in Shopify Functions and market-level catalogue rules rather than in a support agent's head. We map all of it in technical discovery and tell you which parts of Plus you would genuinely switch on.
Scope
What Plus & Headless includes
The same standard of work we run for every client — applied to a Dublin brand’s realities.
Full service detailShopify Functions
Custom discount, delivery and payment-method logic written as Functions. Volume tiers, bundle pricing and B2B rules run server-side instead of via three stacked apps.
B2B on Shopify
Company profiles, price lists, payment terms, quantity rules and a self-serve reorder portal. Wholesale and DTC on one catalogue, one inventory, one admin.
Shopify Markets & Localisation
Multi-currency, multi-language, market-specific catalogues, domain routing and correct hreflang. Expansion without a store-per-country sprawl.
Headless Hydrogen Storefront
Hydrogen on Oxygen with the Storefront API, edge caching and streaming SSR. We build this only when the performance or content case is real, and we say so when it isn't.
ERP, PIM & 3PL Integration
NetSuite, Business Central, Akeneo or a 3PL wired in through a documented middleware layer with retry logic, error alerting and a reconciliation report.
Scoped and quoted for your Dublin store
We do not work off a rate card. Every Dublin engagement starts with a fixed statement of work — named deliverables, named dates, one number — written after we have looked at your store, not before. If a smaller first step would serve you better, we will say so.
Get this scopedHow it runs
From kickoff to results
Technical Discovery
We map your systems, order flows and edge cases end to end, then document where data breaks today. Output is an architecture diagram you can hand to any engineer.
Solution Design
Native-versus-custom decision for every requirement, with cost and maintenance load attached. Plenty of requests get answered with a $0 native setting.
Build in Sprints
Two-week sprints in a dev store with a staged demo at the end of each. You see working software every fortnight, not a status deck.
Load & Failure Testing
Peak-traffic simulation, payment-failure paths, partial-sync recovery and a rollback plan. We break it in staging so BFCM doesn't break it live.
Launch & Enablement
Phased rollout, monitoring dashboards and training for ops and finance. Every custom component ships with a README and a named owner.

Supplements (Subscription DTC)
~$4.2M/yr, 60% subscription revenue, 22 SKUs, US · Shopify Plus (Recharge, Klaviyo)
Monthly subscription churn hit 9.4% and the cancel flow was a single button on a hosted page nobody had touched in three years. Support processed 340 subscription changes a month by hand because customers could not do it themselves. The named constraint: no forced logins. The brand refused to gate account access behind a password reset, which ruled out every off-the-shelf portal.

Home Goods & Furniture
~$11M/yr, 2,300 SKUs, configurable upholstery, US · Shopify Plus + Hydrogen storefront (Oxygen)
Fabric, leg and size options turned 2,300 SKUs into more than 40,000 variant permutations, and the Liquid theme rendered a configurable PDP in 6.9 seconds on mobile. Collection filtering ran client-side, so 40% of shoppers left before the first product painted. The named constraint: the ERP stayed. It was the single source of truth for stock and lead times and was not up for replacement.

In their words
Clients on this work
Reorder time 20 min → 3 min
“We sell wholesale into about 400 accounts and were still taking reorders by email like it was 2009. They built the B2B catalog on Shopify with net-30 terms and per-account price lists, and moved our whole rep team onto it in one week. Average reorder went from roughly 20 minutes of back-and-forth to under three.”
Director of WholesaleFood & beverage brand, ~$22M/yr · Dallas, TX
Verified client, 2025LCP 4.1s → 1.3s
“A Hydrogen build plus a NetSuite sync that our own team had failed at twice. Inventory finally matches between the warehouse and the storefront, which sounds boring and is the most valuable thing anyone has done for us this year. LCP went from 4.1s to 1.3s. The honest part: the first six weeks felt slow and I genuinely wasn't sure we'd picked right — it only clicked once we moved to a standing Thursday call with the engineers instead of account-manager summaries.”

Plus & Headless in Dublin — your questions
No. Markets and multi-currency work on standard Shopify, and plenty of Irish brands run three markets perfectly well without upgrading. Plus becomes worth it when you need checkout extensions, native B2B for stockists, or Functions to enforce destination and quantity rules server-side. We model the fee against what you would actually switch on rather than assuming the upgrade.
By selling GB delivered-duty-paid, which means collecting the duty and import VAT at checkout and prepaying the carrier. It depends on having correct commodity codes and country of origin on every product, and that data is usually the real work — most catalogues we inherit have neither. Once it is in place, refused deliveries and the chargebacks that follow drop off sharply.
Yes. Company profiles carry multiple buyers, price lists are assigned per company and per currency, and quantity rules can reflect case packs rather than single units. Net terms and self-serve reordering cover most of what an Irish brand's wholesale desk does by email today. Where it stops is contract-level quoting and bespoke configuration, and we tell you which side of that line you sit on during discovery.
Only when there is a genuinely different legal entity, a different assortment and separate fulfilment behind it. Otherwise you are maintaining duplicate catalogues, split inventory and two theme codebases, and you have created an SEO problem for yourself. Markets gives you country-specific domains and pricing without any of that, which is almost always the better trade for a brand of this size.
Usually not. A well-built Liquid theme hits sub-2s LCP and costs a fraction to run. Headless earns its keep when you need a custom front-end framework, a heavy CMS-driven content layer, or interactive product configuration Liquid cannot serve. We will talk you out of it if the numbers don't hold.
No. Shopify has retired it in favour of checkout extensibility, and anything still running on it is on borrowed time. We migrate custom checkout logic into checkout UI extensions and Functions, which survive platform upgrades instead of blocking them.
For most mid-market brands, yes. Company accounts, per-company price lists, net payment terms and quantity rules cover the majority of wholesale workflows natively. Where it falls short is complex quoting and contract pricing, which we handle with Functions or a light custom app.
