Residential house cleaning is one of the lowest-friction service businesses you can start: the demand is permanent (homes get dirty on a schedule), the tooling is cheap, and the revenue is recurring. A single weekly client signed in month one can still be paying you in year three. That recurring nature is the whole game — you are not chasing one-off transactions, you are building a route of repeat visits.
Fill the route before you optimize anything. Five reliable recurring clients is a real business; a logo and a website with zero clients is a hobby. Spend month one knocking on doors and over-delivering, month two collecting reviews and referrals, and month three deciding whether to stay solo (higher margin per hour) or hire to grow (higher total revenue, more management).
