Shopify Developer in Auckland: Custom Apps and Fixes for NZ and AU Stores
Custom Shopify apps, accounting and inventory integrations, GST tax invoice setup, migrations to Shopify and theme fixes for New Zealand and Australian merchants. Two Shopify apps of our own as proof.
A Shopify app developer in New Zealand, with two apps of our own
NullGlitch is based in Hobsonville, Auckland. We build custom Shopify apps, integrations and fixes for New Zealand and Australian merchants - the jobs where an app from the App Store almost fits, or where nothing fits at all.
We are also a Shopify app developer in our own right. NullGlitch Tax Invoices is live on the Shopify App Store and NullGlitch Back in Stock is coming to it. The Admin API, webhooks, theme app extensions and app proxy behind those two apps are the same tools we use on client work.
Looking for a Shopify developer in Australia? Australian merchants are welcome. We work remotely, you deal directly with the person who builds the work, and the tax invoice work covers Australian ABNs and adjustment notes as well as New Zealand GST numbers and credit notes.
What’s included in Shopify Development for NZ & AU Stores
Built around commercial clarity, faster delivery, and clean execution.
Custom Shopify apps
An app built for one store, or for a problem that many stores share. We have built and run two of our own, so we know what it takes to get an app working properly and through Shopify review.
Integrations: accounting, inventory, shipping
We connect your store to the systems around it - accounting, stock and shipping - when they have a documented API. We confirm what the API allows before we quote.
GST and tax invoice setup for NZ and AU
Tax invoices with your GST number or ABN, credit notes in New Zealand and adjustment notes in Australia. Use our app as it is, or have us adapt the documents to your store.
Migrations to Shopify
Moving from WooCommerce or another platform: products, customers and order history, with 301 redirects from the old URLs so search traffic is not thrown away.
Theme fixes
Broken sections, awkward layouts and small changes that should not need a rebuild. If a fix is better done as a theme app block than as edits to your theme, we say so.
How the project runs
Clear phases, no mystery, and no padded process theatre.
Scope
We agree what the work has to do, which systems it touches and what a finished result looks like, in writing.
Build
We build it against a development store so your live store is not used for experiments.
Test
We check the results against real orders and real numbers before you rely on them.
Hand over
You get the work, a plain explanation of how it behaves, and the estimate reconciled against actual hours.
Shopify apps we have built and run
The work on this page is not theory. These are our own apps, and each has its own page on this site.
NullGlitch Tax Invoices
GST tax invoices for Australian and New Zealand Shopify stores, with NZ credit notes and Australian adjustment notes, showing your ABN or GST number.
NullGlitch Back in Stock
Back-in-stock email alerts for Shopify stores, with fixed plans and clear logs. Built and running on our own infrastructure; Shopify review is next.
Technology behind the build
Modern tools where they matter, without making the stack the sales pitch.

Store data
Webhooks

Theme app extensions
