Scheduling software solves a single, specific problem: the back-and-forth email exchange that turns booking an appointment into a 3-5 day process. The solution is a booking link — the client picks a time from your available slots, and both parties receive calendar confirmations automatically.
The differences between Calendly, Acuity, and HubSpot Meetings determine which fits your specific booking workflow.
What each tool is built for
Calendly was designed for individual and team scheduling with a clean, modern interface. It’s the most widely recognized scheduling tool and has become the standard for professional service bookings — “send me your Calendly” is a common phrase in professional communication.
Acuity Scheduling (owned by Squarespace) was designed for service businesses that manage appointments as a core business function — health practitioners, fitness instructors, spas, consultants. It handles service menus, staff scheduling, package sales, and payment collection.
HubSpot Meetings is a scheduling tool built into HubSpot’s CRM platform. It’s included with HubSpot Free and paid tiers. Its key advantage is native CRM integration — every booking automatically creates or updates a contact record.
Pricing comparison
| Plan | Calendly | Acuity Scheduling | HubSpot Meetings |
|---|---|---|---|
| Free | 1 event type, unlimited bookings | No free tier (7-day trial) | Included in HubSpot Free |
| Entry paid | $10/month (Standard) | $16/month (Emerging) | Included in HubSpot Starter ($15/seat) |
| Mid tier | $16/month (Teams) | $27/month (Growing) | Included in HubSpot plans |
| Full features | $16/month per user | $49/month (Powerhouse) | Included in HubSpot plans |
The pricing picture: HubSpot Meetings is effectively free if you’re already using HubSpot. Calendly’s Standard tier at $10/month is the lowest-cost dedicated scheduling tool. Acuity’s entry point is $16/month (slightly higher than Calendly) but includes features Calendly doesn’t offer until higher tiers.
Feature comparison
Calendar integration
All three integrate with Google Calendar and Outlook/Microsoft 365. Calendly and Acuity also integrate with iCal. All three prevent double-booking by checking your real-time calendar availability before showing open slots.
HubSpot Meetings’ calendar integration is seamless within the HubSpot ecosystem but slightly less smooth with calendars outside it.
Video conferencing
| Tool | Zoom | Google Meet | Microsoft Teams |
|---|---|---|---|
| Calendly | ✅ Auto-generates | ✅ Auto-generates | ✅ Auto-generates |
| Acuity | ✅ Auto-generates | ✅ Auto-generates | ✅ Auto-generates |
| HubSpot Meetings | ✅ Auto-generates | ✅ Auto-generates | ✅ Auto-generates |
All three automatically generate and include video conferencing links in the booking confirmation. This is standard functionality across the category.
Payment collection
| Tool | Take payment at booking | Deposits | Packages | Gift certificates |
|---|---|---|---|---|
| Calendly (paid) | ✅ | ❌ | ❌ | ❌ |
| Acuity | ✅ | ✅ | ✅ | ✅ |
| HubSpot Meetings | ❌ | ❌ | ❌ | ❌ |
The clear winner for payment-required bookings: Acuity. If your business model requires payment or deposit at booking — health practitioners, fitness studios, spas, photography, coaching — Acuity’s payment features are comprehensive in ways Calendly doesn’t match.
CRM integration
| Tool | HubSpot native | Salesforce | Other CRMs |
|---|---|---|---|
| Calendly | Via Zapier/Make | Via Zapier/Make | Via Zapier/Make |
| Acuity | Via Zapier/Make | Via Zapier/Make | Via Zapier/Make |
| HubSpot Meetings | Native — automatic | ❌ | Via Zapier/Make |
The clear winner for HubSpot users: HubSpot Meetings. Every booking automatically creates a contact, logs the meeting, and can trigger workflows without any integration setup. For Salesforce users or other CRMs, Calendly’s third-party integrations work well.
Customization and service menus
Acuity wins here. Acuity allows you to create a full service menu — different appointment types, durations, prices, intake forms, and staff assignments. A wellness clinic with 5 practitioners offering 8 service types at different durations and prices is exactly Acuity’s use case.
Calendly supports multiple event types on paid tiers but is less designed for complex service menus.
HubSpot Meetings supports multiple meeting types but doesn’t have the service-business-specific features (intake forms, service packages, staff assignment) that Acuity provides.
Reminders and follow-up
All three send automated confirmation emails. For reminders:
- Calendly (paid tiers): customizable email reminders at user-defined intervals
- Acuity: highly customizable email and SMS reminders with significant content control
- HubSpot Meetings: basic reminders included; deeper reminder customization via HubSpot workflows
The decision framework
| Business Type | Best Choice | Reason |
|---|---|---|
| Consultant, freelancer, professional service | Calendly Standard ($10/month) | Clean, professional, easy to share |
| Already on HubSpot | HubSpot Meetings (free) | Native CRM integration at no extra cost |
| Wellness, spa, fitness, health practitioner | Acuity ($16-27/month) | Payment, deposits, packages, service menu |
| Large team, round-robin scheduling | Calendly Teams ($16/user) | Best team scheduling logic |
| Multi-practitioner clinic or studio | Acuity Growing ($27/month) | Multi-staff scheduling with individual booking pages |
What to look for if you’re starting from scratch
For most service businesses evaluating scheduling tools for the first time:
- Already using HubSpot? Use HubSpot Meetings and don’t pay for a separate tool.
- Taking payment at booking? Acuity is the right answer.
- Everything else? Start with Calendly Free. If you need multiple appointment types or integrations, upgrade to Standard at $10/month.
The decision isn’t permanent — migrating from Calendly to Acuity (or vice versa) is straightforward because the core function is the same. Start with the simplest option and upgrade when your booking workflow outgrows it.
