The line is not size or income, it is who decides. If your kid sets the price, finds the customers, owns the schedule, and knows the numbers, it is a business at any revenue at all. If those four sit with you and your kid supplies the labor, it is a job you are managing, which is a perfectly good thing and is not the same thing. The useful news is that the gap is four specific handovers rather than a quality your kid either has or does not.
Parents ask this quietly, usually about something that is genuinely working. Two lawns, forty dollars on a Saturday, a kid who does it without complaining. And underneath the question is a worry about whether any of it counts, or whether everyone is being generous about what is really a chore with a neighbor attached.
Revenue is the wrong test, so set it aside first. A kid can make three hundred dollars in a summer and own none of it, and a kid can make thirty and own all of it.
Who set the price? If your kid named a number and would defend it to a customer who pushed back, that is theirs. If you worked out what was fair and told them, the price is yours and it will fold the first time somebody questions it.
Who found the customer? A neighbor you arranged is a favor to you. A neighbor your kid asked is a customer. Both are fine and only one of them is evidence.
Who owns the schedule? If the job happens because you said it is Saturday, you are running operations. If they know what is booked and you find out by asking, it is theirs.
Who knows the number? Ask your kid what they made last month and what they spent. If they know roughly, they are running something. If they look at you, you are.
Most families land in the same place: the kid does all the work and the parent runs the business. That is how it starts and there is nothing wrong with it. It becomes a problem only when it stays there for a year, because a kid in that position eventually senses that the interesting part belongs to somebody else, and that is when they lose interest for reasons nobody can name.
Hand back one thing at a time rather than all four at once. Four at once is not a promotion, it is being dropped.
Start with the price. It is the most visible, the most transferable, and the one that changes how a kid stands in the conversation. Have them work out what the job is worth and name the number themselves, even if the number is wrong. A kid who chose four dollars will defend four dollars. A kid who was handed six folds at five.
Then customers, then the calendar, then the numbers. Somewhere in there it stops being a question you are asking yourself.
You will notice it rather than decide it. They will tell you about a customer instead of you reminding them about one. They will turn down a job because Saturday is full. They will get annoyed about something you would not have thought to be annoyed about.
That last one is the reliable tell. People only get proprietary about things that belong to them.

Take the quizA kid who cuts, edges, and cleans up usually starts between $25 and $40. Professionals charge about $30 to $85 a visit, and a young founder starting below that is being paid less for being unproven, not for being young.
