How an e-commerce project runs
Building a store is as much about planning as code. We keep it structured so launch day is an anticlimax in the best way:
- Discovery - your products, customers, and how people will actually browse and buy.
- Platform and scope - the right platform for your catalogue, with a written scope and fixed quote.
- Design and build - conversion-focused product and checkout pages, built mobile-first.
- Payments, shipping and tax - gateways, shipping zones, and GST configured for Australian selling.
- Testing - real test orders end to end, on desktop and phone, before anything goes live.
- Launch and support - go live, then tune conversion with ongoing support packages.
Before you launch, run through our e-commerce launch checklist for Australian stores. If you are weighing platforms, see WordPress vs a custom build, and how much a website costs in Australia for budgeting.
Ongoing support
E-commerce is never "done" - catalogues grow, platforms update, and conversion rates need tuning. We offer monthly support packages to keep your store fast, secure, and profitable.
