The Independent Consultant
Sells coaching sessions and workshop days on her own and books clients from Germany, Austria and Switzerland. Wants a booking page that looks like her own website, payment taken when the session is booked, a buffer after every call, her private calendar respected, reminders she never has to send herself, and a price that makes sense for one person.

This judge's pick
Calendly
Criterion by criterion
Booking page & client experience
Cal.com
The booking pages are documented with event types carrying their own title, description, duration, slug and location, custom booking questions, optional email verification for bookers, and four embedding options — inline, floating button, element-click pop-up and email — so clients can book without leaving my site. The embed pages describe colours and styles I can match to my brand, a white-labelled widget, mobile-optimised responsive embeds, pre-filled booking forms and bookers who can reschedule with ease. I found no public information on booking pages in several languages, a multi-step choice of service, person and location, or a published accessibility statement.
Calendly
The booking page is well documented: event types with their own name, duration, location and hosts, custom booking questions with a phone field, guests up to ten, an embed for my website with customizable colors, and cancel and reschedule links in the invitations and reminders. Group events, language switching per event type and automatic time-zone detection for both sides push it further, though I found no public information on seat limits for group events, removing the Calendly branding, or an accessibility statement for the booking pages.
Calendar sync & availability rules
Cal.com
Calendar connections to Google Calendar, Microsoft Outlook, Apple/CalDAV and Zoho are documented, sharing event details and free/busy data, and the limits give me buffer time before or after every event, a minimum notice period, a booking horizon and daily, weekly or monthly booking limits. Availability schedules with date overrides let me mark specific dates unavailable, and the free plan page states unlimited event types and calendars. I found no public information on rooms or equipment that must also be free.
Calendly
My two must-haves are documented: built-in buffers and breaks to protect time after a call, and connected Google, Outlook and Office calendars checked for busy times so my private calendar is respected, alongside minimum scheduling notice, booking date ranges and daily, weekly or monthly meeting limits. Paid plans connect up to six calendars, but I found no public information on iCloud or CalDAV, holidays and absences, or resources, and the help pages state connected calendars cannot be assigned to individual event types.
Team, staff & location scheduling
Cal.com
Round-robin distributed based on availability, weights and priority rules, managed and collective event types, shared or per-host availability, and routing forms with conditions evaluated in order are documented, with team admin and owner the only roles allowed to create or change team event types. The organizations tier adds SAML SSO, SCIM and role-based permissions. I found no public information on several locations with their own staff, reporting per staff member, or audit logs.
Calendly
Far more than I need as one person, but the documentation is unusually complete: round-robin with a configurable distribution method and per-host schedules and locations, collective events, routing forms that can route on Salesforce ownership, centrally managed event types and team templates, plus SSO with SAML and SCIM provisioning, a real-time audit log and round-robin distribution statistics downloadable as a CSV. The only soft spot is that weighted round-robin and locations with their own dedicated staff are not clearly spelled out.
Reminders, payments & no-show protection
Cal.com
Automatic reminders by email and SMS with timing set in minutes, hours or days before an event, WhatsApp messaging, default or fully custom templates, and post-event follow-up emails are documented, triggered by confirmations, cancellations and reschedules — reminders I would never have to send myself. Payment before the meeting through Stripe is described with per-event charges and the charging moment configurable, though the pricing page also names PayPal while the event-type documentation says only Stripe is supported, so the captured pages give different figures for payment providers. I found no public information on enforced cancellation deadlines, no-show or late-cancellation fees, deposits, or a waiting list that refills cancelled slots.
Calendly
Automatic email and text reminders before and after each event, managed per event type and customizable on the Standard plan and up, plus payment at booking through Stripe or PayPal with a worked example reading "Client pays $150 deposit upfront" — that covers my essentials without me lifting a finger. But the help pages state plainly that a cancellation policy is displayed and not enforced, and I found no public information on no-show or late-cancellation fees or a waiting list that refills cancelled slots.
Integrations, API & data export
Cal.com
A documented public API with Bearer-key authentication and OAuth scopes, webhooks with 31 trigger types covering bookings, payments, no-shows and recordings, video locations for Cal Video, Zoom, Google Meet and Microsoft Teams, native Salesforce, HubSpot and Pipedrive connections, an app store of 100+ apps including Zapier, and customer-data export at any time, self-serve or by email, are all documented. An open-source embeddable component package and a self-hosted option under an MIT licence are published. I found no public information on API rate limits or a documented format for the complete export.
Calendly
A documented API with OAuth and personal access tokens, real-time webhooks with a signing key across a long list of resources including scheduled events and custom question answers, plus named integrations for HubSpot, Salesforce, Marketo, Pardot, Microsoft Dynamics and Zapier — more than enough to wire bookings into my own website and tools. Routing form responses export as CSV, though I found no public information on published rate limits, an integrations directory, or a full documented export of bookings and customers.
European sovereignty
Cal.com
Cal.com, Inc. is a Delaware corporation and states that data is processed in the United States with some subprocessors elsewhere, so my German, Austrian and Swiss clients' booking details would cross the Atlantic under the published data processing agreement, standard contractual clauses with the UK Addendum and Swiss amendments, and the EU-US Data Privacy Framework — though the Swiss-US framework does not apply. A subprocessor list is published at the trust centre covering hosting, email, SMS, payments, video, AI and analytics, with prior notice and an objection right before new subprocessors start, and ISO 27001 and SOC 2 Type II certifications are downloadable. EU data residency is offered only on contact, and no EU contracting entity is stated.
Calendly
Calendly is a US company and its data processing agreement states that processing occurs in the United States and other jurisdictions; a subprocessor list is published, but it names almost exclusively US providers, including Twilio for SMS and OpenAI for the AI features. Certifications including ISO 27001 and SOC 2 Type 2 are published and an EEA representative sits in Berlin, yet I found no public information on EU hosting or an EU contracting entity, so my DACH clients' booking data would run through an American chain end to end.
Pricing transparency
Cal.com
The tiers are public with per-user prices: a free-forever plan for one user that already includes Stripe and PayPal payments, email and SMS notifications, round-robin and 100+ apps; Teams at $12 per user/month on yearly billing; Organizations at $28 per user/month; and Enterprise only as Custom with Talk to sales. Business fees are stated to be exclusive of taxes, plans are billed in advance and renew automatically, fees are non-refundable, and signup needs no credit card. I found no public information on the price of SMS credits or payment fees, and only the yearly figures with a 25% saving noted are shown.
Calendly
The tiers are public with their scaling unit: a free plan connecting one calendar, Standard at $10 /seat/mo and Teams at $16 /seat/mo billed yearly, monthly and yearly billing both offered, and month-to-month or twelve-month terms stated in the customer terms. But I found no public information on the price of SMS credits or payment processing fees, and the Enterprise tier runs on invoice billing, so as a one-person buyer I cannot compute my true first-year cost with text reminders from the public pages alone.
