Book a cut into a colour's developing time

28 July 2026 · BookThru

A colour appointment isn’t one solid block of a stylist’s time. There’s the application, then 30–45 minutes of developing, then the finish. During that developing window the chair is busy — but the stylist often isn’t.

Most booking tools don’t understand this. They treat the whole appointment as one opaque block and quietly waste the gap. Over a week of colours, that’s hours of sellable time disappearing.

What processing-window scheduling does

BookThru models a service as its real phases — engaged, processing, engaged — not a single lump. During the processing window the stylist is shown as available, so the system can slot in a shorter service that fits entirely inside the gap.

In practice that means a gents’ cut can be booked into the middle of a colour, and released cleanly the moment the colour needs the stylist back. No double-booking, no manual tetris in the diary.

Why it matters to the bottom line

• More appointments per chair without adding opening hours.
• Fewer awkward gaps that are too short to sell manually.
• Automatic — clients booking online simply see the extra availability.

It’s the kind of optimisation that’s invisible to the client and obvious on the takings. The gap was always there; most software just never let you sell it.

Built in, not bolted on

Processing-window scheduling sits in every BookThru plan, including Free. It’s the scheduling engine’s default behaviour, tested to never place a booking that would collide with a busy cell — even under a rush of simultaneous online bookings.

Set your colour service’s developing time once, and the diary fills the gaps for you.
