Best Appointment Scheduling Software in 2026: Ranked by Job, Price, and Whether Clients Pay at Booking
Calendly, Acuity, Square, and Cal.com solve different jobs. We ranked 6 scheduling tools by meeting-link vs service booking vs POS, and what a $0–$16 seat or a $16–$49 calendar actually includes — plus the FCC texting rules that decide if your reminder is legal.
Appointment scheduling software is not a calendar. It is a booking page that publishes availability, takes a slot, sends a confirmation, and can charge a card before the slot is real. The Google query treats Calendly, Acuity, and Square as rivals. They are not. One sells a meeting link. One sells a service catalog with a deposit. One is a POS that happens to take appointments. Mix those jobs and you pay twice — once for a $0–$16 seat or a $16–$49 calendar, and again when no-shows still land in SMS.
Key Takeaways
- There is no overall best. Rank by job: a public meeting link, a paid service booking, a salon POS, a free multi-staff page, or code you can host.
- The market splits in two. Meeting-link tools (Calendly, Cal.com, Google Calendar) start from your availability. Service-booking tools (Acuity, Setmore, Square) start from a catalog, a staff calendar, and often a card. Mixing those jobs is how a salon buys Calendly and still takes deposits in Venmo.
- The sticker is a deposit. Calendly Standard is $10 per seat per month billed yearly; Teams is $16. Acuity Starter is $16 billed annually ($20 month-to-month) for one calendar. Setmore Free is $0 for four users and 200 appointments; Pro is $5 per user billed annually. Square Free is $0 per location; Plus is $49, plus card processing on every plan.
- A free plan is a cap, not a sandbox. Calendly Free is one event type and one calendar. Setmore Free caps at 200 appointments. Square Free takes bookings but holds no-show fees and multi-staff booking for Plus. Cal.com Free is the only $0 plan with unlimited event types — for one user.
- A reminder text is a consent document. Under FCC TCPA rules, autodialed texts to a wireless number need prior consent. Informational reminders may be oral. Commercial texts need written consent. The scheduler that SMS-blasts a promo from the same number as the reminder is a different product.
What appointment scheduling is (and what it is not)
The product is a closed loop: availability → booking page → confirmation → reminder → (optional) payment → calendar. Availability is Google, Outlook, or a staff roster. The page is a public URL or an embed. Confirmation is email, and sometimes SMS. Payment is a deposit, a package, or a POS swipe. The calendar is the system of record so the slot cannot be sold twice.
That is not time tracking. A clock records hours already worked. This product sells hours that have not happened yet. It is not employee shift scheduling (Homebase, When I Work, Deputy) — a different SERP, a different buyer, a rota instead of a client. It is not an ATS even when recruiters paste a Calendly link into an outreach sequence. It is not a meeting note taker: the note tool joins the call; the scheduler created it.
How we ranked
Five checks, not a composite score: job, meeting link vs paid booking, who gets billed (seat vs calendar vs location), what the free plan actually keeps, and real monthly cost. Prices were checked against official pages on 18 August 2026. Where a live page did not publish a dollar amount, we say so.
Quick picks by job
A public link for 1:1s, demos, and office hours. Calendly Standard at $10 a seat billed yearly if you need unlimited event types, reminders, and Stripe. Cal.com Free if one person and unlimited event types is enough. Google Calendar Appointment Schedules if the booker lives in Gmail and you will not sell a package.
A service business that takes deposits, packages, or classes. Acuity Starter at $16 billed annually for one calendar and payments. Standard at $27 when you need six calendars and SMS. Skip Calendly if the workflow is a catalog, not a meeting type.
A salon, studio, or shop that already swipes cards on Square. Square Free at $0 per location. Budget Plus at $49 when you need no-show fees, waitlists, and multi-staff booking. Do not buy Acuity and Square POS.
Four people, a booking page, and no invoice yet. Setmore Free. Upgrade to Pro at $5 billed annually only when you blow the 200-appointment cap or need SMS.
You want the code, or a Calendly import without the seat tax. Cal.com Free for one user. Teams at $12 billed yearly for round-robin. Self-host if data residency is the point.
Comparison: 6 platforms
Starting prices are the first published lasting tier. Annual billed rates are listed first where the vendor publishes both.
| Tool | Type | Starting price | Best for | Main trap |
|---|---|---|---|---|
| Calendly | Meeting link | Free (1 event type); Standard $10/seat/mo yearly | Sales, recruiting, office hours | Free is one event type; Teams $16 is the router |
| Cal.com | Meeting link (open source) | Free (1 user, unlimited events); Teams $12/user/mo yearly | Devs, self-host, Calendly import | Round-robin and branding strip are Teams |
| Google Calendar | Meeting link | Free Appointment Schedules | People already in Gmail | Payments need Stripe; no staff catalog |
| Acuity Scheduling | Service booking | Starter $16/mo yearly ($20 monthly); 1 calendar | Coaches, clinics, packages | No free plan; SMS and HIPAA are not Starter |
| Setmore | Service booking | Free (4 users, 200 appts); Pro $5–$12/user | Small teams that will not pay yet | 200-appointment cap; SMS is Pro |
| Square Appointments | POS + booking | Free $0/location; Plus $49; Premium $149 | Salons and shops that swipe cards | Processing fees on every plan; no-show fees are Plus |
Meeting-link: Calendly, Cal.com, Google Calendar
These products sell a URL so someone picks a time on your calendar. Right buy when the unit of work is a meeting. Wrong buy if the unit of work is a haircut, a class pack, or a chair.
Calendly is the default US meeting link. Free is always free: one event type, one connected calendar, a booking page, conferencing. Standard is $10 per seat per month billed yearly: unlimited event types, multiple calendars, Stripe and PayPal, reminders, 24/7 chat. Teams is $16 billed yearly: round-robin, routing forms, Salesforce. Enterprise starts at $15,000 per year. Trap: Free is not a meeting cap. Two event types (a 15-minute intro and a demo) is Standard. Round-robin is Teams.
Cal.com is the open-source version of the same job. Free is $0 for one user: unlimited event types and calendars, email and SMS, Stripe and PayPal, a one-click Calendly import. Teams is $12 per user per month billed yearly: round-robin, remove branding, routing forms. Organizations is $28: SAML, SOC 2, HIPAA. Self-host if the cloud seat is the problem. Trap: two people sharing a pool is Teams.
Google Calendar Appointment Schedules live inside Calendar. A personal Google account or Workspace can publish a booking page with duration, buffers, conferencing, and up to five email reminders. Payments need Stripe. Some controls sit behind Workspace or Google One. Right buy instead of a $10 Calendly seat for one event type. Wrong buy as a staff catalog.
Service-booking: Acuity and Setmore
These products sell the appointment as inventory. Right buy when a client picks a service, a person, and a price. Wrong buy if the only object is “30 minutes on my calendar.”
Acuity Scheduling (Squarespace) is the service-business default. There is no free plan — a 7-day trial. Starter is $16 per month billed annually or $20 month-to-month: one calendar, Stripe/Square/PayPal, email reminders, intake forms. Standard is $27 annually / $34 monthly: six calendars, SMS, packages, gift certificates. Premium is $49 annually / $61 monthly: 36 calendars and a signed BAA for HIPAA. Trap: Starter takes payments; it does not send SMS. The $16 is per account, not per seat.
Setmore is the cheap multi-staff page. Free is $0 for up to four users: 200 appointments a month, payments, a branded page, email reminders. Pro is $5 per user per month billed annually or $12 month-to-month: unlimited appointments, SMS, 2-way calendar sync, a signed BAA. A user is a staff calendar, login or not. Trap: 200 appointments is about 50 a week. A four-person studio will hit it.
POS: Square Appointments
Square folded Appointments into Square Free, Plus, and Premium. Free is $0 per location: online booking, reminders, unlimited staff calendars. Processing still applies: 2.6% + 15¢ in person, 3.3% + 30¢ online. Plus is $49 per location: no-show fees, multi-staff booking, waitlist, 2.5% + 15¢ in person. Premium is $149 and 2.4% + 15¢. Right buy if the register and the book are the same company. Wrong buy for a meeting link.
Worked monthly cost at three team sizes
Assumptions: US business, annual billing where published. Square is software only — processing extra. Acuity is one account, not per seat.
| Size | Calendly Standard | Cal.com Teams | Acuity Starter | Setmore Pro (annual) | Square Free | Square Plus |
|---|---|---|---|---|---|---|
| 1 person | $10 | use Free | $16 | $5 | $0 + processing | $49 + processing |
| 4 people | $40 | $48 | $16 (1 calendar) | $20 | $0 + processing | $49 + processing |
| 10 people | $100 | $120 | $16 (still 1 calendar) | $50 | $0 + processing | $49 + processing |
The $0 columns are the trap and the save. Cal.com Free and Google Calendar are a save for one person. Setmore Free is a save until appointment 201. Square Free is a save if you were going to swipe cards, and a trap without the processing rate. Acuity’s $16 does not climb with headcount — it climbs with calendars. A ten-person Calendly Standard bill at $100 is why a one-book coaching practice should not open on seats.
The FCC rules the reminder has to survive
Software does not make a text legal. Consent does.
The FCC’s TCPA consumer guide (reviewed 27 February 2026) is the source. Autodialed texts to a wireless number need prior consent. Commercial texts require written consent. Informational texts may be oral. Appointment reminders are usually informational. A blast that sells a package from the same thread is commercial. Recipients can opt out at any time, even after they consented. A signed BAA (Acuity Premium, Setmore Pro, Cal.com Organizations) is not a TCPA waiver.
Keep reminders on email until the booking form records consent. A no-show fee is a contract: Square puts it on Plus; Acuity can take a deposit on Starter; Calendly Standard collects via Stripe — it does not run a salon cancellation policy.
When it breaks
The billing unit is not the job. Calendly, Cal.com, and Setmore Pro sell seats (or staff calendars). Acuity sells calendars on one account. Square sells locations plus a take rate. Compare $10 to $16 to $49 without naming the unit and you pick the wrong column.
Free is a quota. Calendly: one event type. Setmore: 200 appointments and four users. Square: $0 software, no-show fees on Plus. Cal.com Free: one user.
Two systems of record. Meeting-link tools want Google Calendar. Service tools want a staff roster. Running Calendly and Acuity is a double-book. A time tracker that never sees the booked slot is a third clock.
SMS without a consent field. Turning on texts does not create TCPA consent. The booking form does.
HIPAA as a checkbox. Acuity’s BAA is Premium. Setmore’s is Pro. Cal.com’s is Organizations.
Seat sprawl. Ten people on Calendly Teams is $160 a month before Salesforce is configured. That is a SaaS spend problem. Pull unused seats before Enterprise at $15k.
A 15-minute way to choose
- Write the job in one sentence: people pick a time on my calendar, or clients pick a service and pay.
- If a meeting: Calendly Free or Google Calendar if one event type. Cal.com Free if you want unlimited types on one user. Pay Calendly Standard or Cal.com Teams only for extra types, round-robin, or CRM.
- If a service: Setmore Free if you are four people under 200 bookings. Acuity Starter at $16 if one calendar and deposits matter. Square Free if the register is already Square.
- Put one real week through the trial: one booking, one reminder (email first), one payment or deposit, one reschedule, one no-show rule.
- If step 4 fails on a cap, a calendar limit, a processing rate you did not quote, or a text you cannot prove consent for, change lanes.
