Everything an appointment-led business runs on.

The calendar is the product. Availability is computed from the things that actually determine it, rather than from a static list of slots someone has to maintain.

• Per-location opening hours, staff shifts, and holiday hours all feed the same availability engine.
• Month view shows which days have anything free before a customer picks one, so nobody hunts through an empty calendar.
• Double-booking is prevented at write time, not by convention — a slot taken while someone was filling in their details is refused with a clear message rather than silently overbooked.
• Customers reschedule and cancel themselves through a link, and the appointment being moved is excluded from its own conflict check.
• Time blocks for breaks, admin, and anything else that is not bookable.

• A service catalogue with categories, variants, per-variant durations and prices, and images.
• Packages of pre-paid sessions that draw down as they are redeemed, with expiry.
• Memberships with recurring billing, member pricing, and scheduled downgrades or cancellation.
• Upfront payment rules per service: full payment, a deposit (fixed or percentage), or nothing due until the visit.

• Card checkout through Stripe, and cash recorded at the counter — both settle the same booking and produce the same paperwork.
• Account credit that customers accrue and spend, with a ledger behind it rather than a number someone edits.
• Promo codes that work in booking and in the cart, with a one-use-per-customer limit that is enforced server-side.
• Invoices issued automatically once money is recorded, with terms and a footer each business configures for itself.
• Every invoice is keyed to its payment, so a retried webhook or a re-recorded payment cannot raise a second one.

Customer messages arrive in a shared inbox rather than on one person's phone, so the conversation survives a day off.

• WhatsApp Business inbox with live updates — a reply appears for whoever has the thread open, without a refresh.
• Approved message templates for the notifications WhatsApp requires them for.
• An assistant that answers and books from the conversation, with a prompt each business configures.
• Automations for booking confirmations, reminders, consent forms, aftercare, no-show recovery and lead capture.

• Daily sessions with a time window and a capacity, for businesses that run walk-ins rather than fixed slots.
• Customers see their live queue number and how full a session already is before they set out.
• QR check-in at the door, and check-out that settles what is owed and completes the visit.

• Campaigns over WhatsApp and email, with consent recorded per customer per business and checked at send.
• Ratings and reviews for the business, the practitioner and the service, collected after a visit actually happened.
• Loyalty rewards after a configurable number of visits, and referral codes that credit the customer who introduced someone.
• Short links for sharing a business, a service or a practitioner profile.

• Roles and granular permissions — a front-desk login does not see payroll or settings.
• Multiple locations under one workspace, each with its own hours, staff and calendar.
• Staff profiles and practitioner pages that customers browse and book directly.
• An activity log of what changed, and who changed it.

Customers get an app of their own, not just a booking form. They can hold appointments, packages and memberships at more than one business from the same account.

• Browse and filter businesses by type, rating, city and country, or by what is near them.
• A cart for booking several things at once, with suggestions from the same and other businesses.
• Purchase history with full receipts — business, service, practitioner, location and promo code — and the invoice attached.
• Rate a visit from the receipt it belongs to.
