MainStreetKeys helps people buy and sell small, main-street businesses: the plumbers, HVAC shops, landscapers, pool routes and accounting practices that are too small for most brokers.

• Online Businesses for Sale: structured listings from public online-business marketplaces (asking price, revenue, profit, multiple, niche), ready for deal screening or alerts.
• Practices for Sale: accounting and professional practices for sale, with price, revenue, location and listing links.

Both are pay-per-result, so you only pay for the listings you pull.

• What's my business worth? A quick valuation by trade, with the math shown: https://www.mainstreetkeys.com/worth 
• MCP server for AI assistants: https://www.mainstreetkeys.com/mcp
