Tools & platforms to use
How much can you realistically earn?
Most people who start Micro-SaaS budget around $20–200 to get going, and see their first paying customer, client or sale within 2–5 months. Earnings here scale fastest for people who treat it like a real business from day one — tracking numbers, reinvesting profit, and improving the offer. There's no guaranteed number here — treat any income figures you see online as a ceiling for someone who executed well, not a promise.
