Which booking system is live today?

Phorest. Our Phorest adapter reads services, staff and live availability and creates or changes appointments. It is built and demonstrated in the product; your own salon still has to grant access, and we validate those credentials against Phorest before your line goes live.

Can it work with Booksy or Square Appointments?

Not yet. Both are on the roadmap. Until an adapter is built and tested, a salon on those diaries runs on message taking and transfer to a person, or we scope a custom route with you.

What if we use something else, or a paper diary?

Tell us what you use. We review what its interface allows and tell you honestly what can and cannot be automated before you commit. Where a diary cannot be read, the receptionist still answers, applies your rules, takes a full message and transfers callers.

Do you claim to be a partner of these providers?

No. We build to the published interfaces these providers offer. We are not describing any of them as a partner, approved, endorsed or certified supplier.

Does it take card details or deposits?

Never on the call. Where your booking system offers its own hosted deposit payment link, the receptionist explains that instead.

Booking systems

Booking system integrations, and exactly where each one stands

4sk.ai reads and writes a salon's diary through a booking-system adapter. One adapter is built and demonstrated today — Phorest. Booksy and Square Appointments are planned but not built. Anything else is reviewed with you before you commit, and no system is described as connected until your own credentials have been validated against it.

How the connection works

The receptionist never talks to a booking system directly. Each provider sits behind an adapter with the same contract: read the treatment or service list, read staff and what each of them does, read genuine availability, then create, move or cancel an appointment and record the result.

That is deliberate. Your salon's rules, the conversation on the phone and the reporting afterwards do not change when the diary behind them changes, and a new provider is a new adapter rather than a rebuild.

Before launch we test the journeys that matter with you on demonstration data, and we only put a line live once the connection behind it has been validated.

Availability is read live at the moment the caller asks — it is never cached or guessed.
Every booking action records what was requested, what the provider replied and how it ended.
Credentials are held server-side and encrypted. They never reach a browser.

Current status by provider

Statuses below mean what they say. “Adapter built and demonstrated” means the code exists and has been exercised in the product. It does not mean your account is connected: that always depends on your salon granting access and those credentials being validated.

Phorest — Adapter built and demonstrated. Our Phorest adapter reads services, staff and availability and creates or changes appointments. Your own salon still needs to grant access, and we validate those credentials against Phorest before your line goes live.
Booksy — Planned. On our roadmap. Until it is built and tested, a Booksy salon runs on message taking and transfer, or we scope a custom route.
Square Appointments — Planned. On our roadmap. Until it is built and tested, availability and booking are not automated for Square diaries.
Another system — Scoped per business. Tell us what you use. We review what its interface allows and tell you honestly what can and cannot be automated before you commit.

If your diary cannot be connected

Plenty of businesses ring us with a diary that has no usable interface, or with a paper book. The receptionist still earns its place: it answers every call in your own words, applies your rules, captures the caller's full name, email address and mobile number, and hands your team a proper message instead of a missed-call notification.

We would rather tell you that before you buy than discover it on a real client's call.
