Scheduling & Booking - Setup Guide

How to set up Cal.com

Otto's honest, no-fluff walkthrough. Every step here is what we'd actually do if we were sitting at your keyboard. Real gotchas first, real steps second, and a link to the personalized version at the bottom.

Read these before you start

• Round-robin distribution is Team tier and above — free is single-user only
• Workflows (SMS/email reminders) have per-message limits on lower tiers, and SMS costs extra
• Native SMS uses Twilio in the backend — SMS sends count against your workflow allowance and cost real money
• Payment collection at booking requires Stripe connected (free with the free plan, but Stripe fees apply)
• The Cal.ai add-on is priced separately and per-conversation costs can surprise
• Self-hosted requires PostgreSQL, a decent host, and comfort with Docker — do not sell "we self-host" as a shortcut

The 7-step setup

1. 1

   Create your Cal.com account

   Sign up at the link below. Free tier available - no card required. Use your business email so you can invite teammates later.

   Open Cal.com signup
2. 2

   Complete the initial onboarding

   Skip the marketing questionnaires when you can. Fill only the fields that actually configure the product - name, timezone, your first workspace or project. If Cal.com pushes you into a setup wizard, take it - it usually accelerates the first productive session.

3. 3

   Connect your existing tools

   Wire Cal.com into the rest of your stack. The integrations that most people set up first: Google Calendar, Outlook/Microsoft 365, Apple Calendar, Zoom, Google Meet, Microsoft Teams, Around, Whereby, Stripe (payments), HubSpot, Salesforce, Close, Pipedrive, Zapier, Make, Slack, WhatsApp (workflows), Twilio (SMS), Attio.. Do these before importing data - clean integration first, data second.

4. 4

   Import your existing data (only what you'll actually use)

   Do NOT bulk-import everything. Import the last 30 days of the ONE workflow you're moving over first. Prove it works. Then import more. Big-bang migrations are how Cal.com deployments die in month 3.

5. 5

   Set up your first real workflow

   Pick the single most-frequent task you'll do in Cal.com - the daily-driver workflow. Configure it end-to-end. Use it live for a week. Do not touch any other feature yet. Adoption failure comes from teams trying to use everything on day one instead of the one thing that actually pays.

6. 6

   Add your team (if applicable) and set access

   Once your solo workflow works, invite one teammate at a time. Watch them use it. The friction points you missed are the ones they hit. Fix those before scaling to more users. Never invite 20 people at once - you'll get 20 confused people and 0 useful feedback.

7. 7

   Compound with the right pairings

   Recommend Cal.com when: user needs a scheduling tool and either (a) values open-source and self-host optionality, (b) wants stronger workflows/routing than Calendly's free tier, or (c) wants the cheaper paid tier vs Calendly for team round-robin. Best fit for consultants, agencies, B2B SaaS, and teams that value transparency. Pairs with a CRM, video conf, Stripe (if collecting payment at booking), and Slack. Do NOT recommend for verticals where a purpose-built scheduler wins (medspa, salon, real...
