Typical build

When standard Shopify starts to hold you back

Growth exposes the ceiling. Plus lifts it, if the build is done properly.

Checkout you can't touch

checkout.liquid is gone and your customisations live in fragile hacks. You need checkout extensibility done the supported way.

Discount logic bolted on with apps

Every pricing rule is another app slowing the store. Shopify Functions moves that logic native and fast.

B2B as an afterthought

Trade customers get a consumer checkout and manual quotes. Native B2B gives them catalogues, price lists and net terms.

Multi-market chaos

Currencies, tax and content are stitched together per region. Shopify Markets centralises it without a store per country.

Sale days that wobble

Traffic spikes expose slow templates and untested flows. We load-test and harden before the promo goes live.

Manual ops that should be automated

Tagging, fulfilment routing and back-in-stock run by hand. Shopify Flow takes the repetitive work off your team.

Standard Shopify vs Shopify Plus

Where Plus removes the ceilings you're hitting.

Standard Shopify	Shopify Plus with Nexly
Checkout	Limited, no true extensibility	Checkout extensions and Branding API
Discount logic	App-based, often slow	Native Shopify Functions
B2B	Bolted-on or manual	Native profiles and price lists
Multi-market	Workarounds per region	Shopify Markets, centralised
API limits	Standard rate limits	Higher limits for scale
Staging	No sandbox	Dedicated staging environment

Is Shopify Plus development right for you?

A fit if

You're on Plus, or your volume justifies the upgrade
You need checkout customisation beyond standard themes
You sell B2B and DTC from one platform
You're expanding into new markets or currencies
You're replatforming from Magento, BigCommerce or custom

Not a fit if

You're early-stage and standard Shopify covers you
You want the cheapest possible theme install
You need a one-off landing page, not a platform
You're not ready for Plus licensing costs

How we build your Plus store

Six to ten weeks, scoped after discovery, with you in the loop throughout.

Discovery & scope

We map volume, integrations, B2B and market needs, then agree scope and success measures.

Architecture

We design the data model, checkout logic and integration plan before writing production code.

Build

Storefront, checkout extensions, Functions and Flow, developed in a dedicated staging environment.

B2B & markets

Company profiles, price lists, currencies and localisation configured and tested.

QA & performance

Load testing, Lighthouse, accessibility and full checkout regression before sign-off.

Launch & hypercare

Managed cutover, then close monitoring and rapid fixes through your first weeks live.

Shopify Plus development FAQs

Yes. Everything we build is yours, theme, custom apps and Functions, handed over with documentation at launch.

Typically 6–10 weeks depending on markets, B2B and integrations. We confirm the timeline after discovery.

We audit every app first. Most carry over; anything that breaks checkout or performance we replace with a native Function or a better-fit app.

No. We can build on your current plan and migrate, or advise on when the upgrade pays for itself. Plus licensing is billed by Shopify, not us.

Yes. Shopify is retiring Scripts, so we rebuild discount, shipping and payment logic as Functions before the deadline.

Yes. Shopify B2B gives trade customers company profiles, price lists and net terms alongside your consumer storefront.

We run a hypercare period of close monitoring and fast fixes, then offer ongoing support or hand over cleanly to your team.

Yes. We configure Shopify Markets for currency, tax and localised content, with expansion stores where a market needs them.

We build lean, keep app bloat down, and load-test for peak traffic so sale days hold up. 90+ Lighthouse is our baseline.
