Give clients a booking page that fits how you actually work, then approve every request before it lands in your diary.
Agreeing a time over DMs never really stops. Someone books a slot you were never free for, a "can you do Thursday?" gets buried under three other chats, and you end up being the booking system yourself, evenings and all.
Nailbook gives you your own personal booking link that you can share anywhere: your Instagram bio, a story, a reply to a message. Clients request a time slot that suits them, and nothing lands in your diary until you approve it with one click. If it doesn't suit you, you can propose a different time that works for you both. You stay in control instead of handing your week over.
A client finds your link on a Sunday night and asks for a full set on Wednesday at 6pm, with a photo of their expected result. You are booked until 5, so you suggest 6.30 to give yourself some time to prepare. They accept directly from the email they receive, and it is in your diary before the kettle has boiled.
