The problem it solves
Many businesses rely on inefficient spreadsheets due to high costs and long timelines associated with bespoke software development; this service offers quick and affordable solutions.
How it makes money
Charge a flat fee of $5,000 per project, with high margins derived from the low operational costs of using Fable 5.
Skills you need
Technical skills in software development, familiarity with client interviewing techniques, and expertise in using Fable 5 for generating specifications.
The market, and why this works now
Many med spas and clinics underestimate the cost and time needed for custom software, often relying on inefficient spreadsheets. Leveraging Fable 5, which streamlines development and scoping, this service can deliver tailored software within 48 hours. A viable first-revenue move is to promote the service on the r/medspas subreddit, directly targeting potential clients. A significant challenge in the first year will be the capital required to hire additional software developers as demand grows, impacting scalability.
