Click it, or say it.
The assistant was designed into the booking engine from the start, so it acts through the same rules as every button on the page. Everything in account42 has a button, a form and a calendar. The assistant is there for the moments when typing a sentence is faster than clicking through five screens. You choose, every time.
The usual way
Add a session
For you
For your customers
Under the hood
The assistant only acts through the same booking engine the widget uses. Every change is a transaction with the same seat, payment and refund rules, and it confirms before it changes anything already booked.
The assistant is in your booking page and your dashboard at launch, and in the owner app later. It understands your customers in their language; booking pages come in 12 languages.
Built for people who sell seats.
Studios, gyms, schools, salons, charters and coaches. Anything with a fixed time, a price and a seat count.
Four ways to get paid. One system.
Free
Run a free taster or a community session and still take real bookings.
Under the hood
A free session takes a seat hold and issues a confirmation on the same path as a paid one. Nothing is bypassed because the price is zero.
Drop-in
Sell a single seat in a single session at a set price.
Under the hood
A one-off charge on your own Stripe or PayPal account, captured before the seat is confirmed rather than after.
Membership
Charge monthly and let members book what their plan covers.
Under the hood
Membership status is read at booking time, so a lapsed payment stops new bookings without deleting the member or their history.
Credits
Sell a pack of ten and let customers spend it over the following months.
Under the hood
Credits are spent inside the same transaction that takes the seat, and returned to the balance when a booking is canceled within your window.
All four resolve through one entitlement check. No special cases, nothing configured twice.
Never sells the same seat twice.
Two people tapping Book on the last seat at the same second is not an edge case in a studio. It’s Tuesday. Every hold and booking is a single database transaction, so it can’t happen.
When someone cancels, the waitlist promotes the next person on its own and gives them a time-limited offer. Your cancellation window decides what is refunded, and it runs the same way at 2am as it does at 2pm.

The parts that are hard to get right.
Waitlists that fill the seat themselves
When someone cancels, the next person is offered the seat without you noticing.
Under the hood
A cancellation or an expired hold promotes the next person automatically, with a time-limited offer that passes down the list if it is not claimed.
Packages and courses as one purchase
Sell a six-week course or a multi-session package as one purchase.
Under the hood
One payment, many sessions. Each session is still booked, counted and cancellable on its own.
Recurring weekly schedules
Describe your weekly timetable once instead of adding sessions by hand.
Under the hood
A weekly pattern generates sessions ahead of time, each with its own seats, price and rules.
Cancellation windows you set
You decide how late someone can cancel and what they get back.
Under the hood
The window and its refund behavior are applied at cancellation time, so the rule runs the same way whether or not you are watching.
Reminders that cost you nothing.
Confirmations, reminders and changes reach your customers by email, calendar, Wallet pass and phone notification, free, in every country. Texts and WhatsApp are there when you want them, priced per country and shown first.
Under the hood
The engine sends through the free channels a customer has accepted and confirms delivery where the channel reports it. Paid messages go only where no free channel is confirmed or the change is urgent.
Multi-language, multi-currency, timezone-aware
You set your locale, timezone and currency, and the booking page follows.
Under the hood
Sessions are stored against a real timezone, so a schedule stays correct across daylight saving changes.
Simple on the surface. Serious underneath.
The same three things, described the way a customer meets them and the way they are actually built.
Customers book and pay in under a minute.
Waitlists fill themselves.
It works on your website.
Your money goes to you.
Connect Stripe or PayPal on your own account. Customers pay you, and the money settles to you.
There is no per-booking fee and no commission. account42 is a flat monthly subscription, and a busy month costs the same as a quiet one.
Under the hood
Direct charges on your connected account. We never hold your funds.
Works where you are.
Your currency, your timezone, your language, your own Stripe or PayPal account. account42 is built for wherever your studio is, not adapted to it afterward.
