What you require to say yes, even when you already know the price

By the end, you'll have written, next to the price of each service, the condition other than money the customer has to meet before you book their appointment.

You've got your price locked in, and you don't touch it. Even so, there are jobs you take at the right price and still end up losing money on, and it's not because the client haggled.

A hairstylist charges $90 for a color correction. The price is fair: it covers the dye, the time, and the margin she needs. But if a client shows up with henna-dyed hair and she doesn't find out until they're sitting in the chair, that $90 isn't enough anymore. Some henna products on the market may contain added metallic salts to intensify the color, according to an analysis of commercial products published in RSC Advances. And metals like copper, which hair is thought to absorb even from tap water, react with the peroxide in permanent dyes and form free radicals that damage the hair fiber, according to a study published in the Journal of Cosmetic Science. That means testing a strand first and working more carefully, and that time wasn't in the price.

The price wasn't the problem. Something else was missing: something she needed to know, or something the client needed to bring, before she said yes. We call that a condition, and it's different from the price, even though you set both at the same time.

This isn't about the client who's better off lost. This one you do want, but only if they meet a condition first, one that has nothing to do with how much they're paying.

The condition isn't the price: it's the filter for whether you can do the job right

The price answers one question: what's this worth. The condition answers another, and it comes first: I have what I need to do this without it turning into a mess along the way.

It could be information: a photo of the hair, the history of a recent injury, or the allergies of the guests at an event. That last one isn't a minor detail: the EU regulation on food information points out that some allergies and intolerances pose a health risk, and requires allergens to be listed even on food sold unpackaged. It could be a physical requirement: access to the home two hours before the event, a minimum number of guests, the client providing their own materials, or the exact measurements of the space before quoting a flat price. In every case, the test for whether it's worth writing down is the same: without it, does the job cost you more time, more risk, or more back-and-forth than you're charging for? If the answer is yes, it's a real condition. If the answer is "no, I just prefer it that way," it's a preference of yours. Ask for it if you want, but don't turn it into a condition for booking.

Mixing up the two costs you twice over. If you turn a preference into a condition, you scare off good clients who never had to meet it for you to serve them well. If you let a real condition slide as if it were just your personal quirk, you keep taking jobs that cost you more than you're charging, month after month, without knowing why the numbers don't add up.

Write it in the listing, before the client agrees to a price with you

The condition is worthless if you save it to mention over the phone once you've nearly booked the appointment. By then, the client already has it in their head that this is happening today, and asking for a photo or a note at that point sounds like a last-minute excuse, even though it's exactly the opposite.

It goes in the service listing, right next to the price, in the same tone you use for the price. State it without justifying it: you don't need to explain why you're asking for ID to open a door, just ask for it. Whoever gets it will bring it. Whoever doesn't will move on before ever landing on your calendar, which is exactly what you want.

If the client books and pays through a link, the condition goes before the payment button, not in a message you send after you've been paid. The consumer protection law makes the same point: the relevant contract information, especially its legal and financial terms, has to be given before the client is bound, and if they're buying online and paying, the main features of the service have to be shown right before they place the order. Charging first and asking for the photo afterward flips that order: you've already accepted the job at that price, and whatever you find out after that, you either absorb it yourself or have to renegotiate with the client once they're already standing in front of you. Under the Civil Code, a contract is binding as soon as both parties give their consent. And for construction work it's spelled out clearly: with a flat price set on an agreed plan, you can't ask for more even if labor or materials get more expensive, and the only exception is if the owner approves a change to the plan that adds to the work.

This doesn't replace the listing template you already saw for not writing up every service from scratch: the condition is just one more line in that template, the one that goes right below the price.

One condition, two at most: don't turn it into a checklist

Some people read this and want to armor themselves by listing five conditions in a row, one for every bad client they remember. Don't do that. Every condition you add is one more reason for someone to go message somebody else who asks for less, and most of those reasons don't actually prevent anything: they're accumulated fear, not real risk.

Stick with the one that actually prevents the costly problem, the photo, the note, the ID, and leave the rest for your normal back-and-forth with the client, face to face or by message, where you can still say no without having to write it into the listing.

But sooner or later someone breaks one of your rules and you want to say yes anyway. That's when gut feeling or good will won't cut it: you need a rule of thumb that tells you when that exception is worth it and when it costs you more than you're charging.
