What is SaaS?
SaaS is the default shape of modern software businesses: the product runs on your servers, customers use it through a browser or app, pay monthly or annually, and every update ships to everyone at once. No installs, no version hell, no upgrade sales calls; instead, a continuous relationship where revenue arrives as recurring subscriptions and the product must keep earning its renewal every month.
Why it matters to an indie builder: SaaS is the most accessible scalable business in software history, and the entire stack to run one at indie scale costs less than a coffee habit. The economics compound: recurring revenue, near-zero marginal cost per customer, and churn as the single leak to manage. The strategic trade is honest: you are renting your revenue, subscriptions can cancel, so retention work replaces the launch-and-move-on rhythm of one-off products.
A concrete example: a niche tool for veterinary clinic scheduling. Traditional licensed software: charge 300 clinics 800 euros once, gross 240,000, then starve searching for the next 300. SaaS: charge 60 euros monthly, and after two years the same 300 clinics pay 432,000 annually, every year, while feature requests arrive from a base you already serve. The first year is leaner, every year after is sturdier, and the business is sellable, SaaS trades at multiples of ARR, precisely because the revenue recurs.
Common mistakes: pricing too low to fund support (underpriced SaaS dies of success, every new customer accelerates the burn), treating churn as a quarterly surprise instead of the primary metric, the churn and mrr entries pair with this one, building for everyone and differentiating nowhere, SaaS competition is won by niche depth, and deferring the boring foundations, authentication, billing dunning, backups, until the day they become urgent at 2am. The whole IndieBoot catalog is effectively a parts bin for this business model; billing and hosting blocks are the load-bearing walls.
