Buyer's Guide
If your scheduling tool doesn't sync with Google Calendar, it's creating work, not removing it. Most tutors already live in Google Calendar — the right tool builds on that instead of replacing it.
Most tutors end up juggling multiple systems. Each one has “a calendar” — but none of them are YOUR calendar.
Google Calendar
Your personal + work events
Scheduling app calendar
Tutoring sessions (maybe synced, maybe not)
Billing app records
Invoices that may or may not match your schedule
The fix: Use one calendar as the source of truth. TutorTab treats Google Calendar as THE schedule — not a mirror of some other app's calendar. Create an event in Google Calendar, and it becomes a session with invoicing attached.
Not All Sync is Equal
Every tool claims calendar integration. Here's how deep it actually goes.
The app has its own calendar. You manually copy events to Google Calendar, or you don't — and end up with double bookings.
Example: Wyzant, Venmo + spreadsheet
Events created in the app appear in Google Calendar, but changes in Google Calendar aren't reflected back. You must make all changes inside the app.
Example: Some Calendly setups, basic integrations
Events sync in both directions. But the app still owns the schedule — Google Calendar is a mirror, not the source of truth. You still manage sessions inside the app.
Example: TutorBird, Teachworks, TutorCruncher
Google Calendar IS the schedule. Create events in Google Calendar like you already do. The app watches for changes via webhooks and builds billing on top. No second calendar to manage.

TutorCruncher and Google Calendar (alone) are excluded from this table. TutorCruncher starts at $30/mo and targets agencies, not independent tutors. Google Calendar has no scheduling features beyond basic events.
No new calendar to learn. No app to check every morning. Google Calendar stays your home base.
One-time OAuth setup. TutorTab gets read/write access to your calendar and starts watching for changes via webhooks.
Schedule a session in Google Calendar with the parent as a guest. Use whatever title and description you want.
When TutorTab sees a calendar event with a known parent as a guest, it asks if it's a tutoring session. Confirm, and it's tracked.
After the session, mark it as completed. The invoice is generated automatically based on the session rate and duration.
If the parent has autopay enabled, their card is charged immediately. If not, they get an invoice with a pay button. Either way, you didn't open a billing app.
A booking page lets new parents self-schedule without back-and-forth texting. Not every tool has one.
Shareable booking page (e.g., tutortab.net/book/your-name) where parents select a time from your Google Calendar availability, enter student info, and optionally save a card for autopay. The session appears in Google Calendar automatically.
Built-in booking widget for your website. Parents select a service, choose a time, and book. No payment collection at booking time.
Polished scheduling page with availability rules, buffer times, and automated confirmations. Great for booking but no invoicing, payment collection, or tutoring features. You'll need a separate billing tool.
No public booking page. Sessions are created internally by the tutor or admin. Parents can view their schedule in a portal but can't self-book.

You manage a team of tutors. If you need to assign tutors to students, manage employee schedules, and run payroll, Teachworks or TutorCruncher are built for multi-tutor operations. TutorTab is for independent tutors managing their own schedule.
You don't use Google Calendar. TutorTab's scheduling is built entirely on Google Calendar. If you use Outlook, Apple Calendar, or prefer a standalone app, TutorBird or Calendly may be a better fit.
You only need booking, not billing. If you collect cash and just need parents to pick a time slot, Calendly's free tier does exactly that. No need for a tutoring-specific tool if scheduling is all you want.
Pricing
No subscriptions. No monthly minimums. A fee applies only when a payment goes through TutorTab, and the parent pays it.

How it works
Scheduling, reminders, and invoicing are always free. When we process a payment, a $1 service fee and the card processing fee are added to the parent's invoice. You keep 100% of your rate.
Example
You bill $50? Parent pays ~$52.84 ($50 + $1 service fee + ~$1.84 processing). You receive $50.
You keep 100% of your session price. The service fee is added to the parent's invoice. Payments collected outside TutorTab (cash, Venmo, etc.) are never charged.
No monthly fees. No setup cost. Only pay when you get paid.
FAQ
