The Best Shopify Plus Agencies in Australia (2026): Build Depth, B2B and Integrations Compared

We have one published Australian Shopify Plus build, and we say so plainly rather than imply a bigger base. For Nomad Coffee Group, we put the group’s roaster brands on one Shopify Plus architecture with a self-serve B2B wholesale portal for partner cafés, subscription tooling and national technical SEO. The case page reports wholesale portal orders growing 3.4 times, organic visits up 285%, mobile largest contentful paint down from 3.8 to 0.82 seconds and active coffee subscribers rising fivefold.

That makes us a fit for a business that wants the build and the growth work after it (SEO, paid media, conversion) from one team, particularly if it also sells into Asia. If you need a large Shopify-only team with a long list of enterprise migrations, choose one of the six above. For our scope, see web design and development in Sydney.

Most Australian Shopify Plus projects are migrations from Magento, Salesforce Commerce Cloud, WooCommerce or a custom platform, and most of the risk sits in three places. The first is search traffic. Every old URL that earns visits or links needs a redirect to its closest new equivalent, product and category content has to survive the move, and structured data needs rebuilding on the new templates. A migration that ignores this can lose a large share of organic revenue for months.

The second is operations. Orders, stock levels, customer accounts and, for B2B, negotiated prices all flow between Shopify and the systems behind it. The integration has to be tested with real order volumes, including returns and partial shipments, before launch rather than after. Ask who owns the integration when something breaks at 2 am on a sale weekend.

The third is conversion. A new theme can be faster and still convert worse if checkout steps, payment options or account flows change without testing. The better agencies measure conversion before and after launch and run a planned programme of fixes in the weeks that follow. Agree in advance what you will measure, how traffic and revenue will be compared with the same period on the old platform, and what happens if they fall.

Ask for two Shopify Plus projects similar to yours in size and complexity, and speak to those clients. Ask which of your systems (ERP, warehouse, POS, CRM) the agency has connected before, and who maintains the integration after launch. Ask how B2B customers will log in, see their own prices and reorder. And ask what the first ninety days after launch look like, because that is when traffic dips, redirects break and conversion problems surface. An agency that has done this many times will answer each question with examples, not promises. Finally, check who will actually work on your project day to day, and how much of the build is done in-house rather than subcontracted.
