Our Services
Everything Your Shopify Store Needs. One Team. End-to-End Ownership.
From your first design review to ongoing post-launch optimization, here’s what Sigma delivers for Auckland businesses.
Shopify Store Setup, Theme Development & UI Enhancements
Auckland consumers are active online shoppers. They compare across New Zealand and Australian retailers, they notice when a store loads slowly or looks borrowed from a template, and they’ll leave before reaching the product page if the experience doesn’t feel right. Sigma builds Shopify storefronts in Liquid that load fast, reflect your brand exactly, and are structured to convert from the first visit.
- Responsive Liquid themes built from your brand guidelines—not adapted from a shared template library
- Custom Shopify store setup for B2B and B2C, built around New Zealand consumer expectations and local payment methods including Afterpay
- SEO-clean, speed-optimised builds that don’t leave your marketing team dealing with technical debt
- Mobile-first storefronts connected to your analytics and marketing tools before the store goes live
Shopify Plus, B2B & Customisation Services
Auckland has a substantial wholesale and distribution economy—from FMCG distributors servicing hospitality and retail accounts to industrial suppliers with multi-tier buyer relationships. Standard Shopify wasn’t designed for that kind of complexity. Shopify Plus was. Sigma configures it properly for businesses where trade and wholesale are core revenue channels.
- B2B trade portals with custom logins, tiered pricing, role-based access, and catalogue restrictions per buyer tier
- Shopify Plus enterprise setup for omnichannel operations—online, wholesale, and retail working together
- Workflow automation and backend integrations built to stay reliable under trading volumes Auckland businesses generate
- Checkout.liquid customisation for Plus stores—fewer steps and higher purchase completion
Shopify App Development Services
Auckland’s mix of DTC brands, exporters, and wholesale businesses often means very specific operational requirements that prepackaged apps don’t quite fit. Sigma builds custom Shopify apps for the actual business logic yours runs on—engineered properly, tested against real traffic, and built to stay reliable as you grow.
- Custom apps for B2B and B2C workflows that off-the-shelf solutions don’t address reliably
- Apps built into Shopify Flow, webhooks, and metafields—part of the system, not added on as a workaround
- Performance-optimised code that doesn’t add page weight or create latency on your storefront
- Embedded analytics and reporting so your Auckland team has real visibility inside Shopify admin
Shopify App Integration Services
An Auckland business running Shopify in isolation from its ERP, its 3PL, and its accounting system is creating manual work at every order. Sigma builds integrations that connect Shopify to your entire operation—so inventory, orders, and customer data stay accurate across every platform without anyone reconciling it by hand.
- ERP, POS, CMS, CRM, and New Zealand-compatible payment gateway integrations including Afterpay, Laybuy, and POLi
- Real-time order, inventory, and customer data sync—no daily exports and no reconciliation spreadsheets
- Automated workflows that maintain data accuracy without constant oversight
- Shopify analytics and conversion tracking configured before go-live so your data is useful from day one
Shopify Checkout Customisation & Optimisation
New Zealand shoppers have high expectations and low patience for checkout friction. Missing payment options, too many steps, or a checkout that doesn’t behave well on a mobile device all cost Auckland businesses sales they’ve already earned. Sigma fixes this at the Shopify Plus level, where the checkout can actually be rebuilt rather than just restyled.
- Shopify Plus checkout.liquid customisation—Afterpay, Laybuy, credit card, and POLi flows built for how New Zealand buyers pay
- Speed optimisation across the full store, not just the checkout page
- Infrastructure improvements so high-traffic periods—Boxing Day sales, Black Friday, and mid-year clearance events—don’t create downtime
- Funnel analytics and structured A/B testing so every change is measured against actual data
Shopify Migration Services
Most Auckland businesses that come to Sigma with a migration project have built years of organic search rankings on their current platform and can’t afford to lose them. That’s the right concern to have. Sigma has handled enough migrations to know exactly where each one fails—and how to prevent every failure point before the project starts.
- Zero-downtime migrations from Magento, WooCommerce, BigCommerce, or older custom-built platforms
- Full URL redirect mapping so your organic rankings survive the platform switch intact
- Clean, verified transfer of every product, customer record, and order in the database
- Post-migration QA and monitoring—Sigma stays on after go-live until everything is confirmed working
Shopify Support & Maintenance Services
A store that performs well at launch still needs ongoing care. Platform updates introduce conflicts, apps deprecate quietly, and traffic spikes reveal performance gaps that weren’t visible at lower volumes. Sigma’s post-launch support catches these before your customers do—through active monitoring rather than reactive ticket management.
- Proactive monitoring and real-time issue resolution—not a support queue reviewed intermittently
- App and theme updates managed before they create downstream compatibility problems
- Regular security audits and performance reviews aligned to your revenue goals
- Ongoing CRO and new feature development as your Auckland business grows

How We Work
Our Shopify Development Process
No black boxes. No shifting estimates. Every Sigma project follows a six-stage delivery process that keeps SF clients informed and on schedule.
01
Discovery & Strategy
We start with your customers, your systems, and your commercial goals—before any code is written. The brief drives every decision.
02
Theme Design & Customization
Custom or enhanced Shopify themes built for speed and conversion on every device. Design is approved before it goes to engineering.
03
App Development & Integration
Custom apps, ERP connections, payment integrations—built and tested as a complete working system, not assembled in the last sprint.
04
Quality Assurance & Testing
Full performance, security, cross-browser, and cross-device testing before launch. Your customers don’t find the bugs.
05
Store Launch & Deployment
Go-live is a planned, monitored event. Sigma handles deployment and stays on top of the first 48 hours.
06
Ongoing Maintenance & Optimization
Sigma stays on after launch – monitoring, optimising, and building as your Auckland business grows.
Why Sigma
Why Auckland Businesses Choose Sigma for Shopify
Auckland has no shortage of Shopify developers. What it does have a shortage of is certified partners who deliver properly, stay accountable, and don’t disappear after handover.
01
We build for revenue, not just for launch
Going live is the beginning. Sigma designs stores to convert traffic into buyers and keeps improving performance after the store is running.
02
A commerce partner, not a code vendor
Sigma aligns Shopify’s capabilities with how your business makes money. Every recommendation has a commercial rationale.
03
Fast stores. Fewer abandoned sessions.
Page speed and checkout friction directly affect revenue. Sigma builds stores that load fast and don’t place unnecessary obstacles between a buyer and a completed order.
04
Security and Compliance That Holds
ISO 27001:2022 certified. Every engagement includes security practices that protect customer data and support compliance with the New Zealand Privacy Act 2020 – through development, staging, and production.
Certifications
Certified. Not Just Claiming to Be.
In a city where people know what engineering credentials actually mean, we’d rather show them than talk about them. These are active certifications held by the engineers on your project.

Frequently Asked Questions
What does a Shopify development company in Auckland do?
More than most people expect going in. A Shopify development company builds stores, customises Liquid themes, develops custom apps for workflows the app store doesn’t cover well, connects Shopify to ERP and CRM systems, configures Shopify Plus for enterprise requirements, handles platform migrations, and provides ongoing post-launch support. Sigma delivers all of this from structured delivery centres – not through a freelance pool.
What Shopify certifications does Sigma hold?
Sigma is an active Shopify Partner with certifications in Shopify Foundations and Certified Liquid Storefronts for Theme Developers – earned and maintained by the engineers who do the actual work. Beyond those: Adobe Solution Partner (Bronze), AWS Certified Partner, Microsoft Silver Partner, ISO 27001:2022, and ISO 9001:2015. All actively renewed.
Can Sigma migrate our Magento or WooCommerce store to Shopify?
Yes – and it’s something Sigma has done many times with a clear process behind it. We migrate from Magento, WooCommerce, BigCommerce, and older custom-built platforms to Shopify and Shopify Plus. Every URL redirect is mapped to protect your organic search rankings. All product data, customer records, and order history come across cleanly. You don’t discover gaps after go-live.
Does Shopify support New Zealand payment methods and GST requirements?
Yes, with proper configuration. Shopify supports Afterpay, Laybuy, POLi, and major credit cards used by New Zealand shoppers. GST display, invoicing, and reporting can be configured correctly for New Zealand tax requirements. Sigma has experience setting this up for NZ businesses and will make sure your store is tax-compliant and payment-ready before launch.
How much does Shopify development cost in Auckland?
It depends on what you’re building and the complexity of your integrations. A branded DTC storefront is a different scope from a Shopify Plus deployment with ERP integration and custom wholesale functionality. Sigma scopes every project properly, provides a clear estimate before work starts, and holds to it. No ballpark numbers that grow by invoice time.
Can Sigma build a store that sells well in both New Zealand and Australia?
Yes. Sigma has delivered for AU/NZ cross-market businesses before. This typically involves multi-currency configuration, country-specific checkout flows, hreflang and SEO structure for both markets, and integration with fulfilment providers that operate across the Tasman. Sigma will scope exactly what your cross-market setup needs before the build begins.
Can Sigma build a headless Shopify store?
Yes. Sigma builds headless storefronts on React and Next.js using the Shopify Storefront API – suited to businesses that need maximum performance, full design control, or a unified front end across multiple sales channels. Worth being direct: headless adds architectural complexity and ongoing maintenance overhead. Sigma will tell you honestly whether it’s the right choice for your business before recommending it.
Why choose Sigma over a local Auckland Shopify developer?
Auckland has capable local Shopify talent – we’re not suggesting otherwise. What most local freelancers and smaller agencies can’t offer is a structured six-stage delivery process, dedicated QA, enterprise-grade security, and sustained post-launch support. Sigma is a certified Shopify Partner with 20+ years of commerce delivery and 400+ specialists. You get accountability that continues long after handover.
