Is a custom ecommerce design right for your business? 

This is for businesses that: 

• Are launching a new online store and want to get it right from day one 

• Have an existing website that underperforms in conversions, mobile experience or site speed 

• Are replatforming from a legacy solution to Shopify, Magento, BigCommerce or another modern platform 

• Sell B2B or operate hybrid B2B/B2C models requiring complex pricing, account management or quoting workflows 

• Need their website to integrate seamlessly with ERP, PIM, CRM or 3PL systems 

• Want a design built specifically for the Australian market and buyer expectations 

Ecommerce platform development

We design and build ecommerce stores on Shopify Plus, Adobe Commerce, Magento, BigCommerce and OroCommerce. Every project starts with platform selection, we recommend the right architecture for your business model, catalogue complexity, integration requirements and growth trajectory, then build it properly from the ground up. Our developers are certified on each platform and have delivered projects across retail, wholesale, manufacturing and distribution.

Custom ecommerce development

Out-of-the-box functionality rarely covers the full requirements of a serious ecommerce operation. We build custom modules, extensions and features on top of the platform foundation, custom pricing engines, advanced product configurators, complex checkout flows, wholesale portals, subscription logic and more. Our in-house developers write production-grade code built to last, not quick patches that create debt.

ERP, PIM and systems integrations

Integration is where ecommerce projects succeed or fail. We build reliable, maintainable integrations between your ecommerce platform and the business systems it needs to talk to, SAP, Microsoft Dynamics, MYOB, NetSuite, Akeneo, Pimcore and others. Our engineers handle both sides of the connection: the API design, the data mapping, the error handling and the monitoring. No middleware black boxes, no brittle point-to-point hacks.

B2B eCommerce development 

B2B ecommerce is not a simpler version of B2C, it is a fundamentally different technical problem. Customer-specific pricing, tiered discount structures, multi-location account management, purchase order workflows, credit terms, quote-to-order processes and procurement approvals all require deliberate engineering. AcidGreen has built B2B ecommerce platforms for Australian wholesalers, distributors and manufacturers, and we understand the gap between what platforms offer natively and what enterprise buyers actually need. 

Replatforming and migrations 

Migrating an ecommerce platform is a high-risk project when done poorly. We manage the full migration process: data mapping, content migration, URL redirect strategies, SEO preservation, integration reconnection and parallel testing before cutover. Our approach is designed to minimise downtime, protect your organic rankings and ensure your business continues operating throughout the transition without disruption. 

Performance, technical SEO and ongoing development 

A launched ecommerce platform is not a finished ecommerce platform. We provide ongoing development retainers for Australian businesses that need a trusted technical partner to handle feature development, performance optimisation, Core Web Vitals improvements, platform upgrades and continuous iteration. Rather than treating your store as a fixed deliverable, we treat it as a commercial asset under active development. 

Most agencies can design a store. Far fewer can build one that integrates cleanly with your business systems, handles complex B2B requirements and remains maintainable two years after launch. That’s the distinction that matters.

A development-led team with 25+ years of eCommerce delivery in Australia

Since 2003, Acidgreen has been building ecommerce platforms for Australian businesses. Our team is primarily made up of certified developers and solution architects, not generalist project managers outsourcing to offshore developers. When you engage AcidGreen, the people scoping your project are the same people building it.

Certified across all major eCommerce platforms

We hold certified partner status with Shopify Plus, Adobe Commerce, Magento, BigCommerce and OroCommerce. This means we can give you an unbiased platform recommendation based on your actual requirements, and then deliver the build with specialists on whichever platform is right for your business, not the one that’s easiest for us.

Part of the DATASOLUTION Group

AcidGreen is part of the DATASOLUTION group, giving our clients access to over 400 ecommerce specialists worldwide. For complex enterprise projects, we can draw on global technical resources while maintaining local project ownership and accountability in Sydney and Melbourne.

We follow a structured delivery process built around reducing risk and maintaining commercial momentum throughout the project.

Discovery and scoping : We invest time upfront to understand your business model, integration landscape, B2B requirements and growth objectives before writing a line of code. This prevents expensive scope changes mid-build.

Solution architecture : We design the technical architecture, platform configuration, custom module structure, integration patterns, data models, before development begins. You see exactly what you’re getting.

Agile development : We build in sprints with regular review points, giving you visibility of progress and the ability to provide feedback throughout the build rather than only at the end.

Integration and QA : We build and test all integrations in a staging environment, running structured QA against agreed acceptance criteria before any code reaches production.

Launch and post-launch support : We manage the production deployment and provide structured post-launch support, monitoring performance and resolving any issues in the critical period after go-live.
