About the business
A marketplace business connects buyers and sellers, taking a commission or fee on each transaction. Examples include Airbnb, Uber, and Etsy. Marketplaces are powerful when they work but face the chicken-and-egg problem: you need sellers to attract buyers and buyers to attract sellers.
Financial overview
Startup costs range from $5,000 to $100,000.
- Platform development: $5,000 - $80,000
- Payment processing setup: $500 - $2,000
- Supply-side acquisition: $1,000 - $10,000
- Marketing: $1,000 - $10,000/month
- Legal and compliance: $1,000 - $5,000
Expected time to revenue: 3-12 months depending on category and whether transactions happen manually first
Key metrics for your plan
Your business plan should include projections for these metrics:
- Gross Merchandise Volume (GMV)
- Take rate (commission %)
- Liquidity (% of listings that transact)
- Supply and demand ratio
- Repeat transaction rate
Common planning mistakes
- Building the platform before having any supply or demand
- Launching in too many categories or cities at once
- Setting the take rate too low to be sustainable
- Ignoring one side of the marketplace
- Letting buyers and sellers go off-platform after the first transaction
