Estimates for a small start in Australia, not guarantees.

What it is

You design, build and maintain custom software for small businesses, such as booking tools, internal dashboards, customer portals or links between the systems they already use.

Your first three steps

  1. Pick one type of client (for example local service businesses) and list three common problems you could solve
  2. Build a small demo project or case study and put it on a simple website
  3. Register an ABN, set up a contract template and talk to five local business owners about their pain points
Who pays

Small and medium businesses, tradies, clinics, community groups and other organisations that outgrow spreadsheets and off-the-shelf tools.

How it makes money

Fixed-price projects or day rates for the build, plus a monthly retainer for hosting, fixes and updates.

Skills that help
  • Programming in at least one common language
  • Listening to what a client really needs
  • Clear quoting and project communication
Watch out for
  • Professional indemnity and public liability insurance, check what cover clients expect
  • Who owns the code: spell out intellectual property and licensing in your contracts
  • Handling customer data: check your obligations under the Privacy Act and any data breach rules
  • Check whether your turnover will require GST registration
  • Scope creep on fixed-price jobs, agree changes in writing
