Every buyer sees the price they’ll actually pay.
Consumers expect prices with VAT. Businesses think without it. Shopify’s built-in B2B is made for logged-in company accounts — so most stores that sell to both end up showing someone the wrong price.
02 · For business buyers
Verified, then VAT-free.
- VAT numbers checked against the EU’s VIES register
- Verified customers are made tax-exempt, so checkout charges no VAT — or applies reverse charge
- On Shopify Plus, the form can sit inside checkout
03 · For you
Less VAT admin, fewer mistakes.
- Country VAT rates, imported from Shopify Markets in one click
- Different rates per product with tags — books, food, anything reduced
- A CSV of VAT-exempt orders for your accountant
- Pause price switching whenever you need to
04 · For Google
The price Google reads includes VAT.
- Product pages give Google the price including VAT, even while shoppers browse without it

“Will my accountant be happy?”
Every VAT number is checked in the EU’s VIES register, and you can download a CSV of every check and VAT-free order.
“Will Google show the wrong price?”
Product pages give Google the price including VAT, even while business buyers browse without it.

“We had been looking for a VAT toggle switch for a while and tried a few which did not work correctly. T-Selector and the support there were fantastic and got it working perfectly on our store.” “The app works as advertised - it is simple to use and effective with customisation options available. The real benefit was in the setup. We had a complicated process that involved pricing with, without and exempt of GST that required additional programming, plus other apps that impacted pricing display.” “A very good app for B2B or B2C users, it's simple to use and the service from Adam is out of the league. He helped us from start to finish with both implementation and design.” Reviewed by stores in Europe, the UK and Australia.
Web development · Headless Shopify
Stores that load before your customers lose interest.
Besides our apps, we design and build Shopify stores — from clean theme builds to headless storefronts where speed, content and SEO drive growth. Products, orders and checkout stay in Shopify.
Headless, explained
What does “headless” mean?
Every online store has two halves. The back end holds products, stock, payments and orders. The front end is everything the shopper sees and clicks. In a normal Shopify store, a theme welds the two together. Headless separates them: the front end is built as its own fast website and talks to the back end through an API.
Theme store: one theme renders every page inside Shopify. Quick to start — but every app adds its script to the same page, and design stays inside the theme’s limits.
Headless: the storefront is its own website, served from servers close to the shopper. It asks Shopify for products, prices and carts through the API — and the same back end can feed an app, an in-store screen or anything else.
Our default: Shopify as the back end
As a Shopify Partner, we’d rather keep Shopify underneath. It’s simpler, and you keep everything that already works:
- Shopify’s own checkout — with Shop Pay, Apple Pay and Google Pay — maintained and improved by Shopify
- Card payments on Shopify’s PCI DSS Level 1–certified infrastructure
- The admin your team already knows: orders, stock, discounts, Markets and B2B
- Back-office apps keep working, and Hydrogen storefronts can run on Shopify’s own hosting, Oxygen
- One catalogue for every channel — web, app, point of sale and marketplaces
But it works just as well without Shopify
Headless is a way of building, not a Shopify feature. The front end can sit on whatever back end fits:
- →Another commerce platform, or your ERP or PIM
- →A headless CMS such as Sanity, Contentful or Storyblok for content-led sites
- →No checkout at all: B2B catalogues with quote requests, lead generation, bookings, portals and brand sites
When nobody pays online, Shopify is the wrong tool — so we don’t use it. We pick the back end that fits the job, not the other way round.

Why a second matters

Speed comes from how a store is built — headless gives full control over it, but doesn’t guarantee it.
Why headless
What you get — and the catch.
A faster store
Pages show up straight away, even on a phone on 4G — so fewer shoppers leave before the product loads.
Pages are rendered on the server close to the shopper and streamed, with only the JavaScript each page needs.
The catch
Headless isn’t fast by default. Speed comes from discipline — a script budget, an image pipeline, caching. That’s what we build.
A page that stays put
No review widgets or banners pushing the buy button away from the thumb.
Every area has its space reserved from the start, instead of apps injecting content after load.
The catch
You can fix this in a theme too. With many apps it just becomes a constant fight.
Found on Google
Full control of URLs, headings, structured data and languages.
Core Web Vitals are one ranking signal; clean URLs, schema and hreflang do the rest.
The catch
Speed alone ranks nothing. Content and links weigh more — which is why we build both.
Design without theme limits
A store that looks like your brand, with flows a theme can’t do: configurators, calculators, quote requests, monthly pricing.
The storefront is ordinary code. Anything the web can do, your store can do.
The catch
Freedom costs design time. Every build starts with a proper UX phase.
Content that sells
Guides, comparison pages and campaign pages that are as fast as your product pages.
Content from Shopify metaobjects or a CMS mixes freely with product data.
The catch
You lose the theme editor’s drag-and-drop. We set up editing that fits your team.
One back end, every channel
The same products, prices and stock feed your website, an app, an in-store screen or a marketplace.
Every front end asks the same back end through the same API, so nothing is copied or kept in sync by hand.
The catch
Each new channel is still its own front end to design and build.
Changes without risking checkout
New pages and campaigns ship without touching payments or orders.
The storefront is released on its own; checkout and the back end keep running untouched.
The catch
It’s a software project: releases, testing and upgrades need someone who owns them — that can be us.
Fewer apps to pay for
Simple app features built in once — badges, FAQs, size guides, upsell blocks.
No monthly fee for apps that only exist because the theme can’t do something.
The catch
Theme-based apps don’t work headless. Before we build, we go through every app: keep, replace or build in.
When headless isn’t worth it
- A small catalogue where a good theme looks the part — it’s faster to launch and costs less.
- Your store depends on theme apps you don’t want to replace.
- No budget for ongoing development — changes the theme editor handles need a developer in headless.
If a theme is enough, we’ll say so — and build that instead.

Stores we’ve built and improved
“Did loads of website jobs for us and had a great experience. Had an issue which was a fault of our own about 3 months afterwards and the guys sorted it in 24 hours of me sending an email.” “6 out of 5 stars in communication, service and competence. Delivers outstanding work. We will be using Zoe Production for all future support on our store.” “Adam responded instantly and the work was carried out within 24 hours to a very high standard. We also use their VAT toggle app (T-Selector) and find it to be excellent.” Have a store in mind?

Two more apps on the way.
Built the same way as T-Selector: around a problem we ran into ourselves, running Shopify stores.
- T-SelectorShopify App Store · 4.9 out of 5

Named after a daughter. Built from a store.
Zoe Production was founded in Sweden in 2020 and named after Adam’s firstborn daughter, Zoe. We have been a Shopify Partner since 2021.
T-Selector came out of our own store: we sold to both businesses and consumers, and nothing in the App Store showed each of them the right price. So we built it, and launched it in the App Store in 2022.
