What it is

A one-person or tiny studio that designs, builds and supports custom software for clients, such as booking tools, internal dashboards, customer portals or integrations between existing systems.

Your first three steps

  1. Pick one niche (for example, dental offices or home service companies) and list the manual tasks they struggle with
  2. Build a small demo project or case study and put it on a simple portfolio site
  3. Reach out to 10 local business owners and offer a paid discovery call to scope a first project
Who pays

Local small businesses, clinics, contractors, nonprofits and startups that need a specific tool but can't afford a large agency.

How it makes money

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

  • Talking through business problems with non-technical clients

  • Check your city or county for a business license and any home occupation rules
  • Scope creep and late-paying clients can eat your hours, so take a deposit
  • If you handle health or payment data, check the privacy and security rules that apply
