What we do
We plan, design and build online stores on Shopify, WooCommerce and BigCommerce, and headless stores when the case for them is clear. We also take on focused projects for existing stores: new product page templates, checkout clean-ups, migrations between platforms and integrations with inventory, accounting and marketing systems. The services page lists each one.
Who we build for
Our work is aimed at product businesses selling to Australian customers: independent retailers moving online, brands selling direct to consumers, and established stores outgrowing their first setup. Many will also ship to New Zealand or further afield, and some sell to trade buyers as well as consumers.
What we believe about online stores
A store is a set of answers. Every product page should answer the questions that stop people buying: what it is, whether it fits, what it really costs, when it will arrive and what happens if something goes wrong.
Honest prices are good design. Australian Consumer Law expects a total price including GST and unavoidable fees[1], and card surcharges ended on most major card networks in October 2026[2]. Stores that show the real price early are easier to trust and simpler to run.
Fewer moving parts. Every app, plugin and script adds cost, risk and weight. We would rather solve a problem with a setting or a little code than add another subscription.
You should own your store. Your domain, platform account, content and the code we write belong to you. We do not hold accounts in our name or make leaving difficult.
How we work
Each project has a written scope, one named contact and a written sign-off at each stage. Changes are quoted before they start. We build on staging copies, test with real orders and review every store two weeks after launch. The process page sets out the stages and what we need from you at each one.
Our guides
We publish guides for Australian online sellers on the rules and decisions that come up in store projects, from consumer law to PCI DSS. They are written by our editor, Lucas Foster, cite their sources and follow our editorial policy. They are useful whether or not you ever work with us.
What we will not do
- Promise rankings, traffic or sales figures
- Add fake urgency timers, fake stock warnings or pre-ticked paid extras
- Write or arrange fake reviews, which the ACCC says is against the law[3]
- Hide monthly app or licence costs until after launch
- Keep your accounts or code in our name
A new studio, in brief
Cartmavrix is a new studio. We do not show client logos or testimonials because we do not have client work to show yet, and we will not invent any. The store concepts page shows illustrative designs for fictional brands instead, with notes on the thinking behind each.
Ownership and disclosure
Cartmavrix does not publish a street address; we work remotely and by email. The owner of Cartmavrix has commercial interests in web design services. The privacy notice explains how we handle the details you send us, and you can reach us at hello@cartmavrix.store.
