Why Phorest appointments show as blocked time on Treatwell, and what you can do
If you book an appointment in Phorest, Treatwell shows that time as a plain block with no appointment details. That is how Treatwell treats any outside calendar, and it is not something Booking Connect can change.
What Treatwell gets from Phorest
Each stylist you switch on in Booking Connect has their own calendar link. Treatwell reads that link regularly. It contains:
the stylist's working hours, with time outside their shift marked as unavailable;
their Phorest appointments, as busy time, labelled with the service name;
their breaks.
Client names, phone numbers and email addresses are not in it. Treatwell sees that the time is taken, not who it is taken by.
What Treatwell does with it
Treatwell uses the link to know when a stylist is busy, so it doesn't offer those slots. It shows the time as a block in its calendar. It doesn't turn the entry into a Treatwell appointment, so it isn't an appointment with a client attached. New Phorest bookings can take a few minutes to appear, because Treatwell checks the link on a schedule.
Why this matters for visibility
Treatwell's partner team has told salons that adding appointments to the Treatwell calendar helps its marketplace understand your most popular treatments, and gives you a chance to collect reviews. Salons using Phorest often ask whether the calendar link can do this too.
As far as we know it can't: Treatwell only supports blocking time from an outside calendar. We also can't tell you how much weight Treatwell gives to appointments entered directly. See How to get found on Treatwell for the wider picture.
Your options
Leave it as it is. For most salons the important thing is that Treatwell never offers a slot that is already taken. A block does that perfectly, and no client details leave Phorest.
Enter some appointments in Treatwell yourself. If you want the review and marketplace benefit for particular clients, such as phone or walk-in bookings, you can add them to the Treatwell calendar. This is extra work, and the appointment then exists in two places, so think about whether it is worth it. We can't promise it changes your ranking.
Ask Treatwell. If your account manager gives specific advice about external calendars, they are the right people to confirm what it does.
Treatwell bookings are different
This page is about Phorest appointments going to Treatwell. In the other direction, Booking Connect can add each Treatwell booking to Phorest as a proper appointment, with the client's details, instead of a block. See Blocked time or appointments? Choosing how Treatwell bookings land in Phorest.
Booking Connect is an independent service. It isn't run by Treatwell, Phorest, Fresha or ClassPass.
