Questions buyers ask
How do I choose a software development company in Sydney?
Look for production systems similar to yours that the company still supports, ask who will actually do the work and how senior they are, and check who owns the code at the end. A long support record says more than a portfolio of launches. PicNet's software engineering FAQ covers how it handles each of these.
Should I hire a software studio or a senior engineering team?
Studios that lead with design suit consumer apps and launches. Teams of senior engineers suit business systems, integrations and software that has to keep running for years. Many projects need some of both.
Where can I hire a senior software engineering team in Australia?
The options are a firm that supplies a complete team (such as the companies on this page), a contractor marketplace, or recruiting your own. A firm suits work that needs a team that already works together and will support what it builds.
