# Scheduling & Calendar — buyer checklist (RFP)

Derived from ProductArena's evidence-graded user-story taxonomy for Scheduling & Calendar: 55 judged requirements. Priorities mirror story weights (3 = must-have, 2 = should-have, 1 = nice-to-have).

## Agent scheduling

- [ ] **[must-have]** My agent can check availability, book, reschedule, and cancel meetings end to end through the API or MCP — no dashboard needed
- [ ] **[should-have]** Agents can use my scheduling account as a tool — an MCP server or tool-calling surface exposes availability, bookings, and event types

## Agenticness

- [ ] **[must-have]** Connect an agent via an official MCP server

- [ ] **[nice-to-have]** Test against a sandbox environment without touching production data

## Ai scheduling

- [ ] **[should-have]** AI schedules my tasks into real calendar blocks around meetings and deadlines, and re-plans automatically when things change
- [ ] **[should-have]** The product auto-defends recurring focus time and habits, flexibly moving them when conflicts appear instead of dropping them
- [ ] **[nice-to-have]** AI finds and continuously optimizes the best meeting time across all attendees' calendars, not just the first open slot

## Automation depth

- [ ] **[must-have]** Define rules that trigger actions automatically on events
- [ ] **[should-have]** Perform bulk operations across many items at once
- [ ] **[should-have]** Schedule recurring jobs or workflows
- [ ] **[nice-to-have]** Version, review, and roll back my automations

## Booking links

- [ ] **[must-have]** Share a booking link where invitees pick a time from my live availability — no back-and-forth email
- [ ] **[must-have]** Invitees always see slots in their own time zone — detection, display, and DST handling are automatic
- [ ] **[should-have]** Offer multiple event types with their own durations, locations, custom questions, and confirmation rules
- [ ] **[should-have]** Protect my calendar with buffers before and after meetings, minimum notice, daily booking caps, and date-range windows
- [ ] **[nice-to-have]** Collect payment (e.g. via Stripe) at the moment of booking for paid sessions

## Calendar management

- [ ] **[must-have]** Connect several calendars (Google, Outlook, Apple) and every one is checked for conflicts so I never get double-booked
- [ ] **[should-have]** Busy blocks sync between my work and personal calendars automatically so all my schedules stay in step
- [ ] **[should-have]** Define availability schedules with working hours, date overrides, and out-of-office periods

## Developer platform

- [ ] **[must-have]** A documented REST API lets me manage event types, availability, and bookings programmatically — enough to build scheduling into my own product
- [ ] **[should-have]** Webhooks notify my systems in real time when bookings are created, rescheduled, or canceled
- [ ] **[should-have]** Self-host the full scheduling engine from source or a container image under an open-source license

## Embeds integrations

- [ ] **[should-have]** Bookings flow into my CRM and automation stack (Salesforce, HubSpot, Zapier) without manual copying
- [ ] **[should-have]** Embed the booking experience in my own site — inline, popup, or floating widget — with a documented snippet

## Meeting workflows

- [ ] **[should-have]** Automated reminder and follow-up sequences (email/SMS) fire around every booking to cut no-shows
- [ ] **[should-have]** Invitees can reschedule or cancel from their confirmation, with my policies enforced and calendars updated everywhere
- [ ] **[should-have]** Every booking gets a video conference link automatically (Zoom, Google Meet, Teams, or native video)

## Openness

- [ ] **[must-have]** Export all of my data in open formats and leave
- [ ] **[must-have]** Self-host the core product
- [ ] **[should-have]** Do everything through the API that I can do in the UI
- [ ] **[should-have]** Read the product's source under an open license

## Pricing plans

- [ ] **[should-have]** The free tier covers real individual scheduling — a usable booking link without a paid plan
- [ ] **[nice-to-have]** Published per-seat pricing tells me exactly what each tier costs and includes before I talk to sales

## Privacy posture

- [ ] **[must-have]** Prevent my data from being used to train AI models
- [ ] **[should-have]** Choose where my data is stored (region/residency)
- [ ] **[should-have]** Control data retention and deletion
- [ ] **[should-have]** Opt out of telemetry and usage tracking

## Team scheduling

- [ ] **[should-have]** Offer collective events that only show slots when every required host is free
- [ ] **[should-have]** Inbound meetings distribute across my team round-robin, with weighting or priority so load stays fair
- [ ] **[nice-to-have]** A routing form qualifies invitees and sends them to the right person or team based on their answers
