Acuity Scheduling vs SimplyBook.me: A Per-Calendar Tool vs a Booking-Metered One in 2026?

Updated August 2026

If you run a salon, a therapy practice, a tutoring business, or any service where clients book and pay for an appointment, you've probably already run into both of these names. Acuity Scheduling and SimplyBook.me solve the same basic job: put a booking page in front of clients, take a deposit or a full payment up front, and keep a staff calendar from double-booking. From the outside they look like near-identical software. The pricing model underneath is anything but, and it changes which one is actually cheaper for your specific business.

Acuity Scheduling charges in US dollars, scales its price by how many calendars you're running, and has never offered a free plan, only a 7-day trial. SimplyBook.me charges in euros, offers a free tier that never expires, and instead meters your account by how many bookings you take each month. That's the real fork in this comparison: a US tool with no free door in but no ceiling on booking volume, against a EUR tool that lets you start at zero but asks you to watch a second dial as the business grows. This guide walks through both at real provider counts so you can see which trade actually fits your business.

TL;DR

Key Facts

• Acuity Scheduling has no free plan at all, only a 7-day free trial with no card required, per Acuity's pricing page.
• SimplyBook.me's Free tier never expires: EUR 0/month, capped at 50 bookings a month, 1 provider, and 1 premium custom feature, per SimplyBook.me's pricing page.
• The global appointment scheduling software market was valued at USD 546.1 million in 2025 and is projected to reach USD 1,905.90 million by 2034, a 14.70% CAGR, per Fortune Business Insights.
• In a GetApp survey of 217 US consumers, nearly 70% said they would choose to book online if given the choice, and 94% said they would be more likely to pick a new service provider that offered online booking, per GetApp research.
• A 2025 study in Frontiers in Digital Health found online booking cut no-shows at a private medical practice (1.8% online versus 5.9% offline) but the effect reversed at a university hospital (14.3% online versus 11.2% offline), per PMC, meaning self-scheduling alone doesn't guarantee fewer no-shows.

Who Each Tool Is Really For

Both tools sell to the same broad category of business, service providers who take appointments and money at the same time, so the split between them isn't about the market they serve. It's about how each one wants to be paid for serving it.

If you're actually deciding between booking meetings and booking paid client appointments, rather than between two client-booking tools, our Calendly vs Acuity Scheduling comparison covers that fork instead.

Pricing: Two Different Meters

This is the section that actually decides the comparison, because Acuity and SimplyBook.me don't just charge different amounts, they charge for different things entirely. Acuity's price moves with how many calendars your tier allows. SimplyBook.me's price moves with how many bookings you take each month, how many providers you run, and how many of its "custom features" you turn on, all priced in euros instead of dollars.

Acuity Scheduling, per Acuity's pricing page: No free plan, just a 7-day trial. Starter is $20/month billed monthly, or $16/month billed annually, and covers 1 calendar. Standard is $34/month billed monthly, or $27/month billed annually, and covers up to 6 calendars. Premium is $61/month billed monthly, or $49/month billed annually, and covers up to 36 calendars. An Enterprise tier exists with unlimited calendars and VIP account management, but its price isn't published. No tier meters how many bookings you take.

SimplyBook.me, per SimplyBook.me's pricing page, priced in EUR: Free costs EUR 0/month forever, capped at 50 bookings a month, 1 provider, and 1 premium custom feature. Basic is EUR 13.9/month billed monthly, or EUR 11.9/month billed annually, covering 100 bookings a month, 3 custom features, and 5 providers. Standard is EUR 29.9/month billed monthly, or EUR 24.9/month billed annually, covering 500 bookings a month, 8 custom features, and 15 providers. Premium is EUR 59.9/month billed monthly, or EUR 49.9/month billed annually, covering 2,000 bookings a month, unlimited custom features, and 30 providers. Enterprise is custom-priced with custom bookings, features, and providers.

Read that middle row carefully, because it doesn't flatter either tool by accident. At 5 providers, Acuity Standard runs $408 a year billed monthly, or $324 billed annually, for six calendars and unlimited bookings every month. SimplyBook.me Basic, capped at a similar 5 providers, is cheaper on paper at roughly EUR 143 to EUR 167 a year, but it also caps the whole account at 100 bookings a month. If those 5 providers are booking anywhere close to 20 appointments a month each, you'll hit that ceiling and need to move up to Standard (EUR 24.9 to EUR 29.9/month, 500 bookings a month) before the year is out. Acuity never asks that question, because it doesn't meter bookings at all; the only ceiling is how many calendars you're running. That's the trade underneath this whole comparison: Acuity charges more upfront in dollars for a volume ceiling that doesn't exist, while SimplyBook.me starts cheaper, or free, in euros and asks you to keep an eye on a second dial as the business grows.

Booking Pages, Storefronts, and Custom Features

A booking page has to do more than hold a calendar slot open. It's often the first thing a new client sees of the business, and for a lot of solo operators it doubles as the entire website. Both tools take that job seriously, but they package the deeper capabilities very differently.

The pattern is consistent across every row. Acuity ships most of this as one flat product: it's either there on every tier or it isn't offered at all. SimplyBook.me instead hands you a menu, point of sale, intake forms, custom email, HIPAA compliance, SOAP notes, and asks you to pick which ones matter most within a slot count that starts at 1 on Free, rises to 3 on Basic and 8 on Standard, and only goes unlimited once you're on Premium.

Payments, Packages, and No-Show Protection

Both tools collect payment as part of the booking flow rather than treating it as an afterthought, which is the right call for a category where the appointment often is the sale. Where they differ is whether the money-handling features around that payment are included outright or rationed.

The PMC no-show research cited above is worth remembering here. Online booking by itself didn't reliably cut no-shows across both sites studied, so whichever tool you pick, the deposit and cancellation-fee tooling is doing the real work, not the booking link alone. If your business leans on deposits and no-show fees to protect revenue, Acuity ships that natively at every tier; on SimplyBook.me, some of the surrounding money features (packages, gift cards, memberships) will need a custom-feature slot you may need to plan for in advance.

Classes, Group Bookings, and Multi-Location

Neither tool assumes every appointment is a single provider meeting a single client. Both support group and class formats, though SimplyBook.me publishes more of this as native, always-on scheduling behavior rather than a paid add-on.

If your business runs recurring classes across more than one location, this section alone may settle the comparison. SimplyBook.me treats multi-location and group scheduling as part of the base product at a lower tier than Acuity does, which matters more than the headline price once you're running a studio or clinic with several sites instead of a single practice.

Integrations and Calendar Sync

Both tools sync against the major calendar providers, so double-booking isn't a real risk on either side once setup is done. Where they diverge is which second system each one is built to plug into.

If your business is already inside the Squarespace ecosystem, that overlap with Acuity isn't a coincidence. Squarespace owns Acuity Scheduling, which is worth knowing if you're evaluating website platforms at the same time as booking software.

Implementation Effort and Time to Value

When Acuity Scheduling Is the Right Call

• You want a straightforward, dollar-priced US tool and don't mind that there's no free tier at all, only a 7-day trial.
• Your booking volume is unpredictable or high, and you don't want a monthly bookings cap to ever be a variable you have to plan around.
• You want deposits, packages, gift certificates, memberships, and no-show fee rules built into the core product, with nothing gated behind a feature-slot count.
• Payments, Zoom or Google Meet video, and Squarespace-adjacent branding are already familiar territory for how your business operates.

If you're comparing Acuity against a wider field rather than against SimplyBook.me specifically, our best Acuity Scheduling alternatives roundup covers other client-booking tools worth a look.

When SimplyBook.me Is the Right Call

• You want to test appointment booking software for free before spending a cent, with a Free tier that never expires rather than a countdown trial.
• Your business bills and budgets in EUR, or a euro-denominated tool is simply a better fit for how you already operate.
• You run classes, group sessions, or multiple locations, and you're comfortable choosing which premium features matter most within your tier's slot limit.
• You want native embeds into WordPress, Facebook, Instagram, and Google Business listings, so the booking page lives everywhere your business already has a presence, without paying US-dollar list price from day one.

If you're comparing SimplyBook.me against a wider field, its own field of alternatives is worth scanning, especially if the dual booking-and-feature meter puts you off.

If Neither One Fits

Neither a per-calendar tier nor a booking-volume meter might be the exact shape of your problem, and that's a normal outcome. A few other directions worth a look:

Cal.com is the open-source route: free for a single user with unlimited event types and calendars, and $12 per user per month for Teams, a figure Cal.com shows under a "YEARLY" label with a "Save 25%" badge and no month-to-month rate beside it. Pick this if you want to self-host or need developer-level control over the booking flow, rather than either Acuity's calendar-count tiers or SimplyBook.me's booking-volume meter. Our best Cal.com alternatives roundup is a useful next stop if the open-source model isn't the fit either.

Vagaro, Fresha, or a wellness-specific platform is the better direction if your bookings are classes, memberships, or packages rather than one-to-one appointments. Acuity and SimplyBook.me both handle a salon or clinic well until class scheduling and membership billing become the actual job, at which point the best Mindbody alternatives roundup covers the vertical properly.

Setmore offers a genuinely free plan for up to 4 users with no seat cost and no booking-volume meter, a fit for a small team that wants Acuity-style unlimited bookings without Acuity's price tag. If a team outgrows that free tier, the Setmore alternatives roundup covers where they tend to move next.

Rework takes a different approach entirely: booking is one module (E-Booking) inside a wider operations platform that also runs your CRM, pipeline, and cross-team workflows. It's built for mid-size, cross-functional teams, roughly 10 to 200 people, not solo practitioners or small service shops choosing between a calendar-count tier and a booking-volume meter. Rework's booking capability has no published price; it's quoted per organization. See rework.com/pricing for current details. If you only need an appointment page, Rework is overkill. If scheduling is one piece of a bigger ops puzzle you're trying to consolidate across departments, it's worth a look.

Decision Framework

What to Do Next

1. Count your real booking volume, not your calendar count. If you're already averaging a few hundred bookings a month across providers, SimplyBook.me's meter will matter more than its sticker price.
2. Decide which currency you'd rather budget in. A EUR price and a USD price aren't the same trade once exchange rates move against you.
3. List the "custom features" you actually need (payments, memberships, gift cards, POS, HIPAA) before picking a SimplyBook.me tier, since the slot count is the real ceiling, not the monthly fee.
4. Try before you commit. Acuity's 7-day trial and SimplyBook.me's permanent free tier are both real ways to run actual clients through the booking flow before paying anything.
5. If the real problem is bigger than scheduling, look at how booking fits into your wider CRM, pipeline, or ops stack. Our best CRM software roundup is a reasonable place to start that broader evaluation before you commit to a point solution you'll need to replace in a year.
