My kid will not raise their prices, what do I do?

Telling them the number is too low does not work, and it is worth understanding why before trying something else.

The price is not the result of a calculation, so correcting the calculation changes nothing. Your kid arrived at that number by imagining saying it out loud to an adult and shaving it until it stopped feeling rude. What they are pricing is their own discomfort, and a parent saying you should charge more does not touch that at all.

What does touch it is evidence they gather themselves. Have them look up what a local business charges for the same job. When a kid who charges twelve dollars finds out the company down the road charges fifty, the argument stops being between them and you and starts being between them and a number. That is a much better argument to lose.

Then name what the gap is for, because most kids have it backward. The discount is not for being young. It is for being unproven, which is a temporary condition that twenty jobs and a few neighbors who vouch for them have already ended. Framed that way, raising the price stops feeling like arrogance and starts feeling like paperwork.

Take the fear out of the mechanics. Raising it on new customers requires no conversation at all, just a different number in a sentence they were already saying. Nobody has to be told anything. Most kids have never considered this and it removes most of the dread in one move.

Then run the rehearsal, which is the part only you can do. Have them say the new number out loud to you. If their voice rises at the end, turning it into a question, the problem is not the number. They have not decided the work is worth it yet, and that conversation is the actual work.

What to avoid: setting the number yourself. A price your kid chose survives a customer pushing back. A price you chose folds at the first question, because they were never holding it.

And let them stay too cheap for a while if they insist. A summer of being underpaid teaches this lesson better than you can, and the kid who works it out themselves never forgets it.
