A Shopify Plus build, then three years of growth on the same store.
We built the Plus store around a deep wig catalogue, then kept it moving: the brand’s SEO programme implemented every month with every URL kept, and retention on Attentive bringing customers back for their next install.

A custom Shopify Plus theme with Zenoti booking built in.
Every Book Now goes straight to the right Zenoti service or location, the marketing team edits every section without a developer, and server-side tracking reports each booking to GA4, Meta and Google Ads.
“We’re so pleased with the new theme and custom functionality.”

Who this is for
You need Shopify Plus development if...
- 01
Traffic
Traffic spikes worry you
Big campaigns or flash sales mean crossed fingers instead of confidence your store will hold up
- 02
Checkout
Checkout feels generic
You need custom logic, bundles, gifting rules, or BOGO, and the default checkout won’t bend to fit.
- 03
Wholesale
Wholesale is manual
B2B orders come in over email instead of through a real portal with tiered pricing and net terms.
- 04
Repetition
Your team repeats busywork
Product launches, tagging, and inventory checks are still done by hand instead of automated with Flow.
- 05
Scale
You're expanding into new markets
New regions or currencies need a store built to handle them, not a patchwork of workaround apps.
- 06
Slow
Your store feels slow
Bloated apps and unoptimized code are costing you conversions on every device, every day.

The real difference
Template build vs custom Plus development
Here’s what changes when a store is engineered for scale instead of assembled from off-the-shelf pieces.
| Area | Template / app-stack build | Custom Shopify Plus development |
|---|---|---|
| Checkout logic | ✕ Default flow, app patches | ✓ Custom-built via checkout extensibility |
| Site architecture | ✕ Stock theme, generic structure | ✓ Purpose-built for your catalog and traffic |
| B2B / wholesale | ✕ Bolted-on third-party app | ✓ Native B2B on Shopify, built to fit |
| Automation | ✕ Manual, repeated by staff | ✓ Shopify Flow, tailored to your workflow |
| Performance under load | ✕ Slows or breaks during spikes | ✓ Engineered for high-volume traffic |
| Integrations | ✕ Disconnected point apps | ✓ Unified ERP, CRM, fulfillment setup |
| Global selling | ✕ Single storefront, single currency | ✓ Multi-store, multi-currency via Markets |
| Code ownership | ✕ Locked into app vendors | ✓ Clean, documented code you own |
| Support after launch | ✕ Ticket queue, slow turnaround | ✓ Direct relationship with your build team |
| Scalability | ✕ Rebuild needed as you grow | ✓ Built once, built to outgrow itself |

How we work
Our Shopify Plus Development Process
A six-step system that takes a store from audit to launch with nothing left to guesswork, so you always know what’s next and why.
Discovery and requirements
We review your goals, current challenges, and operational workflows. This helps us understand where your store stands today and define a clear Shopify Plus direction that supports long-term growth.
Week 1Strategy and technical planning
A structured plan is created that covers layouts, custom features, integrations, automation logic, and performance targets. This roadmap guides the entire build and keeps every step organized and predictable.
Week 1–2Design and experience architecture
We shape a responsive, consistent design system that reflects your brand and supports smooth customer journeys. Every layout, component, and interaction is designed to improve clarity, speed, and purchasing flow.
Week 2–7Shopify Plus development
We build a strong Shopify Plus foundation with clean Liquid, optimized scripts, and scalable structures. Custom features, integrations, and Plus-exclusive capabilities are implemented with precision and stability in mind.
Week 6–7Testing and quality review
Your store is tested across devices, browsers, and workflows. We check speed, accuracy, reliability, and integration behaviour to ensure the entire system performs as expected under real-world conditions.
Week 7–8Launch and ongoing support
We review your goals, current challenges, and operational workflows. This helps us understand where your store stands today and define a clear Shopify Plus direction that supports long-term growth.
Week 6–7Frequently asked questions.
What is Shopify Plus, and how is it different from Shopify?
Shopify Plus is Shopify’s enterprise platform designed for high-volume brands. It offers advanced APIs, full checkout customization, unlimited staff accounts, automation tools, and priority support. Unlike standard Shopify, Plus provides the scalability, performance, and flexibility needed for fast-growing eCommerce businesses.
When should a business upgrade to Shopify Plus?
Most brands move to Plus once they’re hitting checkout customization limits, paying high transaction fees on outside gateways, running B2B through spreadsheets, or seeing their store slow down during big traffic spikes.
Can Shopify Plus handle high-volume traffic and large sales events?
Yes. Shopify Plus is built on infrastructure designed for flash sales and major campaigns, staying stable under heavy load, and we pair it with Launchpad automation so drops go live without manual scrambling.
How much does Shopify Plus development cost?
Shopify Plus development is sold as fixed-scope tiers: a launch or a replatform at $40,000–$100,000 (4–10 weeks), a Plus build with integrations at $100,000–$200,000 (12–14 weeks), and headless or multi-storefront work quoted as one build. Every build is quoted as one written number after a call. Ongoing plan cost is separate and billed by Shopify directly.
Can Shopify Plus integrate with ERP, CRM, and other enterprise systems?
Yes. Shopify Plus connects with ERP, CRM, fulfillment, and analytics systems through its expanded API limits and native integration tools, giving growing brands one unified operational setup instead of disconnected point solutions.
What automation tools come with Shopify Plus?
Shopify Flow and Launchpad ship with every Plus plan, automating product launches, order tagging, inventory alerts, and routine workflows so daily operations run with less manual work and fewer errors.
Can Shopify Plus support global eCommerce expansion?
Yes. Multi-store and multi-currency features let brands manage regions and markets from one Plus account, with Markets handling currency, duties, and localized pricing as you expand into new countries.
How long does it take to build on Shopify Plus?
A custom Shopify Plus development project typically takes 6 to 12 weeks depending on scope, covering theme development, checkout logic, integrations, and testing before a scheduled launch.
How customizable is the Shopify Plus checkout?
Fully. Checkout Extensibility lets us build custom checkout UI, discount logic, shipping rules, and payment customizations through Shopify Functions, something standard Shopify’s checkout doesn’t allow.
What ongoing support does Shopify Plus include?
Every build we ship includes post-launch monitoring and a support window, and Shopify Plus itself includes priority merchant support alongside the dedicated engineering relationship we maintain with every client.
