Read ArticleFrequently Asked Questions
Can you really start a business for under $100?
Yes — service businesses, resale operations, and digital agencies can launch for $20-$97. The key is starting with zero inventory (service-first) or minimal inventory (thrift flipping). Your biggest cost is time, not capital.
What's the fastest micro business to profit?
Service-based businesses profit fastest because there's no inventory cost. A social media management agency ($20 Agency model) can land a first client in 1-2 weeks. Resale businesses (thrift flipping) can profit from Day 1 if you source correctly.
How do you calculate break-even for a micro business?
Break-even = Fixed Costs ÷ (Revenue Per Unit - Variable Cost Per Unit). For a service business with $50/month in tools and $500/client revenue, you break even at 1 client in 10 days. Our calculator does this math instantly.
