Booking tools are not all built for the same type of business. Calendly is simple and polished. Acuity Scheduling packs in a lot of features. Amelia runs on your own WordPress site and has no monthly fee once you own a licence. Which one you should use depends on your setup, not which one is most popular.
This is a straightforward comparison of all three — what each one does well, where each one falls short, and a clear recommendation for each type of business.
Quick Overview
Calendly is a SaaS tool built around scheduling meetings and consultations. One person sends a link, the other picks a time. It's the easiest booking tool to set up and the most recognisable brand in the space.
Acuity Scheduling (now part of Squarespace) is a more feature-rich SaaS platform. It handles packages, intake forms, payment collection, and multiple service types. It's a better fit for service businesses than Calendly.
Amelia is a WordPress plugin. You install it on your own site, and it runs entirely on your hosting account. No monthly SaaS fee — just an annual or one-time plugin licence. It handles multi-staff, multi-service booking with a booking flow that looks and feels like a proper app.

Calendly
Calendly is the fastest way to let someone book time with you. You connect your calendar, set your availability, and share a link. That's it.
It works extremely well for a narrow use case: one-on-one meetings and consultations where the booking decision is simple. A prospect wants to talk — here's a link, pick a time.
Where it struggles: Calendly was not built for service businesses. If you run a salon, gym, or clinic, you need more than a meeting scheduler. Calendly's multi-service support is limited. The client-facing experience doesn't show a proper service menu, staff bios, or pricing in any meaningful way.
Payment collection exists but it's basic — you can require payment to confirm a Calendly booking, but there's no real packages or membership support.
Multi-staff is available on paid plans but the interface is clunky compared to Acuity or Amelia.
Best for: Consultants, coaches, and freelancers who primarily book discovery calls or single-session consultations. Also solid for B2B sales teams managing demo calls.
Acuity Scheduling
Acuity is a more complete booking platform. It was purpose-built for service businesses before Squarespace acquired it, and that heritage shows.
You can create multiple service types with different durations and prices. You can set up packages and gift certificates. Intake forms are flexible — you can ask whatever you need before a client's first appointment. Payment collection is tighter: Stripe, PayPal, and Square are all supported.
Multi-staff support is solid. Each staff member gets their own availability schedule, and clients can pick who they want. This works well for small teams.
Calendar integrations cover Google, Outlook, and iCal. Zoom and Google Meet integration is built in for virtual sessions.
The downside: you're paying a monthly SaaS fee forever. The price starts at $20/month (Emerging plan) and goes to $61/month (Powerhouse) for advanced features like multiple locations. If you're running a high-volume business with a full team, that's reasonable. For a solo operator or a small business that just wants to take bookings, the cost adds up.
You also don't own the platform — your booking data lives on Squarespace/Acuity's servers.
Best for: Service businesses with multiple staff or service types that don't already have a WordPress site — coaches, therapists, personal trainers, and beauty businesses that want a robust tool without the complexity of self-hosting.
Amelia
Amelia runs on WordPress. You install the plugin, configure your services and staff, and clients book directly on your site — no redirect to a third-party platform, no "Powered by Acuity" branding.
The booking flow is genuinely well-designed. Clients pick a service, choose a staff member (if you have multiple), select a date and time, fill in any intake fields, and pay — all in one embedded widget that matches your site. It looks like a proper app, not a bolted-on form.
Pricing is different from the SaaS tools: you pay once (or annually) for the plugin licence rather than a recurring monthly fee. The basic licence is $79/year. A one-time lifetime licence is available. Once you own it, your hosting cost is the only ongoing expense.
Multi-staff is built in at no extra tier cost. Each employee has their own schedule, services, and breaks. You can show staff bios and photos on the booking step.
Payment collection works with Stripe, PayPal, and WooCommerce. You can take deposits rather than full payment upfront.
The catch: Amelia requires WordPress. If you don't already have a WordPress site, you need to set one up before you can use Amelia. That's more upfront work than signing up for a SaaS account.
Best for: Service businesses already on WordPress that want full control of their booking experience with no ongoing platform fee — salons, clinics, fitness studios, and any multi-staff or multi-service business.
Pricing Compared
At the low end, Calendly's free plan works for a single calendar and basic bookings. Acuity has a 7-day trial but no free tier. Amelia requires a paid licence from day one.
Over 12 months:
- Calendly Standard (1 user): ~$120/year
- Acuity Emerging: ~$240/year
- Acuity Growing (6 staff): ~$420/year
- Amelia Basic licence: $79/year
If you run a 3-person team on Acuity's Growing plan for 3 years, you've spent over $1,200 on the booking platform alone. An Amelia one-time lifetime licence is a one-time cost regardless of team size.
That math matters if booking is core to your business and you plan to run it long-term.
Calendar Integrations
All three tools connect to Google Calendar and handle the basics — syncing appointments, blocking out unavailable times, preventing double-booking.
Acuity has the widest native integration set. Google, Outlook, iCal, Zoom, and Google Meet all work out of the box. If your team is distributed and lives in calendar apps, Acuity integrates more cleanly.
Calendly also handles Outlook well, which matters for businesses working with corporate clients.
Amelia's calendar integration is primarily Google Calendar. It's less deep than the SaaS tools but covers what most service businesses actually need.
When None of These Is Enough
Booking tools — even good ones — are widgets. You add them to an existing site or link out to a platform. What they don't do is build a booking-first website around your business.
If your site is a generic WordPress theme with a booking plugin dropped in, clients who don't already know you are unlikely to book. They're looking at your site to decide whether to trust you. A generic layout with no clear services page, no team bios, and no social proof doesn't build that trust.
A purpose-built booking website is different. It's designed from the ground up to convert visitors into bookings:
- A homepage built around your services and who you serve
- A services page with pricing, duration, and what the client can expect
- Team member pages that help clients pick the right person
- A booking flow that feels native — not an embedded widget on a page that wasn't designed for it
If you're in a competitive service market — beauty, wellness, fitness, coaching, photography — the site that looks professional and makes booking easy wins.

The Short Version
Use Calendly if you're a solo consultant or freelancer booking one-on-one calls and you want something set up in 10 minutes.
Use Acuity Scheduling if you're a service business with multiple staff or service types and you don't have — or don't want — a WordPress site.
Use Amelia if you're already on WordPress and you want full ownership of your booking experience with no monthly platform fee.
Build a proper booking site if booking is the core of your business and you need a site that earns trust and converts strangers into clients — not just handles scheduling for people who've already decided to book.
We build done-for-you booking websites on WordPress using Amelia — fully set up, mobile-optimised, and ready to take bookings from day one. Fixed price, no calls required.
