How it works

AgendaWPP

AgendaWPP books appointments inside WhatsApp without a back-and-forth chat. The client taps a button and an official WhatsApp form (Meta's WhatsApp Flows) opens inside the same conversation, with the business's logo. They pick the service, the professional, the day and the time, and the appointment is written to that professional's Google Calendar. Only times that are actually free are shown, so the form cannot book an hour the business does not have. The form comes already built and connected to Google Calendar. The business does not design or code anything: what it sets up in its panel is exactly what the client sees in the form. That includes services with price, duration and the days they are offered, discount offers that expire on their own, a photo and description for each professional, hours, breaks, buffer time, minimum notice, holidays, multiple locations, and the name of what is booked (professional, court, room, or any custom name). Optional features include a waitlist that notifies clients in order by WhatsApp when a slot opens, without double bookings, and weekly recurring bookings (same day and time every week). Clients can reschedule or cancel from the chat. Reminders go out at the times the business chooses, up to 5 per appointment, and clients confirm attendance with one tap. An optional AI assistant can answer questions, qualify leads and take the client to the booking form. The AI handles the conversation and the form closes the booking. The same booking rules also apply to AI agents connected through the API or the MCP server. AgendaWPP uses Meta's official WhatsApp Business API (AgendaWPP is a Meta Tech Provider). It includes a web inbox, a contact CRM, a web panel and an installable mobile app, up to 10 users with permissions, and statistics with CSV export. It is available in Spanish and Portuguese for any business that books appointments: barbershops, clinics, dentists, beauty and spa, therapists, vets, consultants, sports courts and rooms.

Agendio

Agendio is a booking platform for leisure and service businesses in Spain —indoor playgrounds, birthday party venues, sports centres and gyms, restaurants and academies— that takes the whole booking process into WhatsApp. Customers book the way they already do, by sending a WhatsApp message, and Agendio's AI assistant handles availability, confirmation, paperwork and access, 24/7 and without staff involvement. What it does: • AI chatbot on the WhatsApp Business API that answers in natural language, checks availability in real time and confirms the booking inside the chat. • Access control: integrates with automatic door and lock systems and sends each customer a temporary access code for their booking slot, with a real-time log of entries and exits and a staff notification for every access. • Automatic documentation: booking contracts, invoices, email confirmations and reminders 24 hours before the event, adapted to the GDPR. • Central management: calendar with weekly, monthly and yearly views, special events and blocked dates, prices and packages, users and permissions, and real-time reports. • Multi-location: several centres from a single panel, each with its own WhatsApp number or all on one. • Google Calendar sync. Setup takes under 30 minutes and needs no technical knowledge: the Agendio team configures the chatbot with the business's opening hours, prices and services. Pricing: from €99 per month, depending on booking volume and number of centres, with a 14-day free trial and no credit card required. A 30-minute guided demo is available. Built by CEDESA DIGITAL S.L. (Badajoz, Spain).

AI Growth Kit

AI Growth Kit is an AI phone assistant for local service businesses. When you or your team can't pick up, missed calls forward to the assistant, so you keep your own business number. The assistant tells every caller up front that it is an automated assistant. It then finds out what the job is, takes the caller's name and number, and books the appointment into your calendar. It handles calls in English and Spanish, so Spanish-speaking customers can be helped in their own language. Setup is done for you. We set up the assistant around your services and hours and connect it to your calendar, so there is nothing for you to build. We also offer a chat assistant for your website that answers questions and books appointments the same way. We do not keep call recordings or transcripts. You can try it free for 14 days, and no card is needed to start.

AiKlient

AiKlient is a booking app for nail techs, hairdressers, beauticians and small salons that works inside Telegram and WhatsApp. Clients book appointments themselves with buttons and see only real free slots, so double bookings can't happen. The booking bot sends automatic reminders a day and two hours before the visit, and answers routine questions — prices, address, directions — with AI, using only your own information. Every account gets a free business page with online booking that you can also embed on your website, plus two-way Google Calendar sync and iCal for iPhone and Outlook. The dashboard covers the team calendar, staff schedules, client base and PDF invoices, in eight languages including Latvian, Lithuanian and Estonian. A simpler, messenger-first alternative to Booksy, Fresha and SimplyBook.me. First month free with full access, no credit card. Then €15/month, no commission.

Alhabla

Alhabla is an AI receptionist for small appointment-based businesses in Spain, such as hair salons, barbershops, nail and beauty salons, spas and physiotherapy clinics. It answers the business's calls at any hour, weekends and holidays included, so no client is left unanswered while the team is busy. What the receptionist does: - Answers questions about services, prices and opening hours, and books, moves or cancels appointments with the professional best suited to each service. - Books into Google Calendar, Outlook or Apple iCloud, or into Alhabla's own agenda for businesses that don't use any of them. - Sends the client a WhatsApp confirmation, and clients can also write to the business on WhatsApp. - Speaks Spanish and seven other languages, plus Catalan, Basque or Galician depending on the region, and always says it is an AI. - Logs every call with a transcript and outcome. Recording is optional and only happens if the caller allows it. Your assistant on WhatsApp: the owner can update services and prices, opening hours, one-off closures, blocked time, the team, a staff member's absence and bookings, and ask about the agenda and recent calls. Alhabla proposes and the owner confirms: nothing changes until the owner taps "Confirm". Setup takes minutes.
