Shopify Plus Development
We build Shopify Plus stores from scratch, or rebuild and improve the store you already have.

Plus problems need Plus-level engineering.
Plus is built to hold exactly the places standard Shopify reaches its limit: a launch that spikes traffic tenfold in a minute, a B2B price list running next to your retail catalogue, a group of stores that all need to move together.
We work at that level as standard — checkout extensibility, Shopify Functions and multi-store architecture proven under real peak load, not tested for the first time on your busiest day of the year.
The layer standard Shopify doesn't need.
Shopify Plus exists for businesses that have outgrown the standard plan’s ceiling, and the engineering has to match that. Configuration that’s fine for a smaller store starts to show cracks under real volume — we build for the volume you’re carrying.
Work at this level typically includes:
- Checkout customisation built with Checkout UI extensions and Shopify Functions, tested against real order volume, not a demo cart.
- Scripts migrated to Functions where they’re still running — Scripts are being retired, and Functions handle discount, payment and delivery customisation at checkout instead.
- Multi-store and expansion-store architecture that keeps inventory, pricing and design consistent across every storefront without duplicating the work behind each one.
- B2B functionality running on the same platform as retail — separate pricing, ordering and account logic without a second system to maintain.
- Traffic engineering for planned peaks, so a product drop or seasonal spike doesn’t become the day everything slows down.
- Deeper Admin API and automation work using the additional access Plus provides, wired in properly rather than duct-taped together.
If you’re already on Plus and the build hasn’t caught up to the plan, or you’re moving up and want it engineered right from day one, this is that work.
Shopify Plus development, answered.
What does Shopify Plus development cost?
It depends on which Plus capabilities you need — checkout extensibility, multi-store, B2B, or all three. We scope the specific work required for your setup and give you a fixed, itemised quote before anything starts.
Do we need to already be on Shopify Plus?
We work with brands already on Plus and brands moving up to it. If you're planning the move, we help you scope what Plus adds for your setup — checkout extensibility, B2B, multi-store — and plan the switch.
Can you customise the Shopify Plus checkout?
Yes — that's one of the main reasons brands move to Plus. We build checkout customisations using Checkout UI extensions and Shopify Functions, tested against your real order volume and edge cases before they ever reach a live customer.
How do you handle B2B and retail on the same store?
Plus supports separate pricing, ordering rules and account logic for B2B customers running alongside your normal retail storefront. We build that layer so wholesale and retail customers each get the right experience without you having to run two separate platforms.
Can you manage multiple stores under one Plus account?
Yes. Multi-store and expansion-store setups are common at Plus level — regional storefronts, separate brands, or B2B and D2C split apart. We architect it so inventory, pricing and design stay consistent across every store without multiplying the maintenance work behind them.
Will our store handle a major traffic spike?
That's engineered in specifically, not assumed. We build and test against the peak load you're expecting — a product launch, a seasonal spike, a marketing push — so the day it matters most isn't the first time the setup's been under real pressure.
