Why Sigma
Wellington is a city that makes careful decisions. Here is what Sigma brings that local freelancers and smaller agencies typically don’t.
Going live is the beginning. Sigma designs stores to convert traffic into buyers and keeps improving performance after the store is running.
Sigma aligns Shopify’s capabilities with how your business makes money. Every recommendation has a commercial rationale.
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.
ISO 27001:2022 certified. Every engagement includes security practices that protect customer data and support compliance with the New Zealand Privacy Act 2020.
Certifications
Wellington is a city that values evidence over assertions. These are active certifications held by the engineers on your project.
From Wellington businesses to global enterprise retailers, Sigma has delivered commerce outcomes that hold.
In Production
Real projects. Verified outcomes. Full case studies on Sigma’s website.
Napoleon Perdis is a well-known Australian cosmetics brand sold across New Zealand too. Sigma migrated them to Shopify Plus, improving store performance and cutting maintenance overhead.
This US brand had three firm requirements for a single Shopify build: subscriptions, wholesale, and WCAG accessibility. Sigma delivered all three without cutting corners.
A global beauty brand running 50+ Shopify Plus stores with inventory errors. Sigma unified inventory management and automated workflows across every location.
What does a Shopify development company in Wellington do?
Quite a bit. A Shopify development company builds stores from scratch, customises Liquid themes, develops custom apps for workflows the app store doesn’t address, connects Shopify to ERP and CRM systems, configures Shopify Plus for enterprise and B2B requirements, handles platform migrations, and provides ongoing post-launch support. Sigma delivers all of this from structured delivery centres – not through a freelance arrangement.
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 held 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 existing store to Shopify?
Yes – and it’s something Sigma has done many times with a thorough 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 rankings. All product data, customer records, and order history come across completely. You don’t discover gaps after go-live.
Can Sigma build Shopify stores for government and public sector organisations?
Yes. Sigma has experience delivering Shopify and Shopify Plus solutions for organisations with procurement compliance requirements, including supplier approval processes, PO-based purchasing flows, access control, invoice payment terms, and audit trail requirements. If your organisation has specific compliance needs, raise them early in the scoping process and Sigma will work through what’s required.
Does Shopify support New Zealand payment methods like Afterpay, Laybuy, and POLi?
Yes, with proper configuration. Shopify supports Afterpay, Laybuy, POLi, and major credit cards used by New Zealand shoppers. GST display and invoicing can also be set up correctly for New Zealand requirements. Sigma configures all of this before launch so your store is payment-ready and tax-compliant on day one.
Can Sigma build a headless Shopify store?
Yes. Sigma builds headless storefronts on React and Next.js using the Shopify Storefront API – suited to Wellington tech companies embedding commerce into a product, or businesses that need full front-end control. Being clear about it: headless adds real architectural complexity and ongoing maintenance overhead. Sigma will assess whether it genuinely fits your situation before recommending it.
Why choose Sigma over a Wellington-based Shopify developer?
Wellington has capable local developers – that’s well known. What most freelancers and smaller local agencies can’t provide is ISO 27001:2022 certified security practices, dedicated QA, a structured six-stage delivery process, and sustained post-launch support. Sigma is a certified Shopify Partner with 20+ years of commerce delivery and 400+ specialists. You get a team that’s accountable after handover, not just during the build.
