Custom Retail & Ecommerce Software Development
Selling online and in store means stock counts, orders and customer records in two or three places. We build online stores, POS and inventory integrations and loyalty tools, usually on top of Shopify or the platform you already run.
Australian retailers rarely have a software shortage. They have a software pile. The online store runs on Shopify or WooCommerce, the counter runs on Lightspeed or Neto, and the two only agree on stock levels when someone reconciles them by hand. A customer buys the last unit in-store and the website keeps selling it, which turns into refund emails and one-star reviews. Click-and-collect orders arrive with no clean way to route them to the right location. And on the website itself, slow pages and clunky checkouts lose the conversions that paid advertising was supposed to win.
If you were searching for shopping cart software, a hosted ecommerce platform is the right answer for almost every retailer starting out or selling a standard catalogue. It handles hosting, checkout, payments and security, and its app ecosystem covers a lot of ground. Custom development pays off once the business outgrows the defaults: stock split across stores and a warehouse, click and collect rules the platform can't express, wholesale and retail pricing in one place, or a stack of monthly apps that still leaves staff reconciling by hand. In most cases we keep the platform and build the integration or feature it's missing.
We connect ecommerce platforms to POS systems so inventory is accurate across every channel, build order management for ship-from-store and click-and-collect, and add Stripe and Afterpay checkout flows. Loyalty and rewards can be built around your margins and repeat-purchase patterns instead of a plugin's assumptions. Retail is also wider than products on shelves: we build booking, lead generation and customer communication systems for service retailers, from salons to automotive workshops.
Card payments in our builds are processed through providers like Stripe and Afterpay, so full card details never touch your systems and the heaviest PCI DSS burden stays with the payment platform; we architect every integration so that remains true. Customer records, purchase history and loyalty data are handled in line with the Privacy Act and the Australian Privacy Principles: hosted in Australian regions, access-controlled, and encrypted in transit and at rest.
IntraCode works from Brisbane with retailers and consumer-facing businesses nationally, and we run our own product, Repify, which automates Google review collection. Every project opens with discovery, where we trace how stock, orders and customers move through the business, and closes with a fixed quote. The code and IP are yours.

Retail Software Questions, Answered
Can you integrate our online store with our POS system?
Yes, this is one of the most common retail integration problems. We build two-way integrations between ecommerce platforms like Shopify, WooCommerce or Neto and POS systems like Lightspeed, using their APIs, so stock levels, pricing and customer records stay in sync across online and in-store channels instead of through manual exports.
What ecommerce integrations do you build for Australian businesses?
Beyond POS, the usual candidates are accounting (Xero or MYOB), warehouse and 3PL systems, shipping and label printing, marketplaces, CRM and email marketing, and supplier feeds. We integrate through each system's API, and we confirm what each one supports during discovery before quoting.
Can you add click and collect to our existing online store?
Yes. Click and collect usually needs store-level stock visibility, rules for which location fulfils an order, pick and ready-for-pickup notifications, and a simple screen for in-store staff. We build that around your existing platform and POS rather than asking you to change either.
Should we build custom or just use Shopify apps?
Use the Shopify app if it covers your workflow. Custom makes sense when apps almost fit: multi-location inventory rules, loyalty tied to your specific margins, or operations that span systems no app connects. You own what we build outright, with no monthly per-app fees stacking up.
How much does custom retail software cost?
A POS-to-ecommerce integration, a custom storefront or a booking system for a service retailer usually starts around $15,000-$40,000. Order management, loyalty and multi-location inventory push it higher, depending on scope. Each quote is fixed-price and follows a discovery session.
Do you support Stripe and Afterpay payments?
Yes. We build checkout flows with Stripe and Afterpay as standard, including subscriptions, refunds and partial payments where needed. Because payments are processed by these providers, full card data never touches your systems, which keeps the bulk of PCI DSS obligations with the payment platform rather than your business.
How long does a retail project take?
A custom storefront or a focused integration typically delivers in 6-10 weeks. Larger omnichannel platforms with unified inventory, order management and loyalty run 3-6 months. Releases are staged, and we avoid cutting over during your peak trading periods, so launches don't put revenue at risk.
