Many Australian cleaners start on lead marketplaces: you buy credits, race to quote, and hope the customer picks you. That cost comes out of your pocket whether or not you win the job.
Booking platforms like Clean Fridays take a different approach for classic residential work. It is free to register and receive offers. You are not charged a fee to accept, and you do not pay to buy a chance at work.
If you are tired of paying for leads that go nowhere, compare free-to-join models with take-home shown upfront against sites that charge before you earn. Also check whether short-stay host bids or NDIS placements fit your skills.
