The Best Appointment Scheduling Software in 2026, Compared From Their Own Pricing Pages

By Uyi Abraham, Founder and CEO, VonzaLast reviewed 14 November 2026Vendor pages read on 14 November 2026

The best appointment scheduling software depends on what you book. For meeting links, Calendly has the best-known free plan (one event type) and per-seat paid plans from $12 a month, and Cal.com’s free plan has no usage limits and takes Stripe and PayPal payments. For appointments at a service business, Acuity Scheduling sells classes, packages and deposits from $20 a month per calendar, Setmore gives up to 4 users a free plan with group classes, Square Appointments bundles a free booking site with Square payments, and SimplyBook.me meters bookings a month. Zoho Bookings suits teams on Zoho, TidyCal sells a lifetime licence, Doodle is the group poll, Appointlet and Koalendar lead with roomy free plans. Vonza suits coaches, consultants, tutors and schools who want the booking, the payment and the follow-up in the account that also sells their courses and community.

Appointment scheduling software gives people a page where they pick a time, answers the question of whether you are free by reading your calendar, confirms the booking, reminds everyone, and often takes the payment. Twelve tools are compared here: eleven competitors and Vonza, which publishes this guide. The table gives each one’s lowest paid price, what its free plan allows, whether payments work on that free plan, and four features (group or class booking, round robin, deposits and SMS reminders) exactly as its own page stated them on 14 November 2026.

The free plans are where these tools differ most, and they meter three different things. Event types or pages: Calendly allows one event type, Doodle one group poll, one booking page and one 1:1, Appointlet one scheduling page. Volume: SimplyBook.me allows 50 bookings a month and Appointlet 25 meetings a month, while Cal.com, Koalendar, TidyCal, Setmore and Square state no booking cap. Seats: Setmore allows up to 4 users and Appointlet up to 5, Zoho Bookings and Cal.com one user each. Payments on the free plan are the real wedge: Cal.com, TidyCal, Setmore, Square and SimplyBook.me take them, Calendly, Doodle, Appointlet and Koalendar move them to a paid plan, and Acuity has no free plan at all.

Platform fees are the exception rather than the rule, but they exist: TidyCal takes 1% of Stripe payments below its Pro plan, and Square is the processor, so its card rates apply to every booking. SimplyBook.me says it charges no transaction fee of its own, and Calendly’s payment fee did not appear on the pages we read. Vonza lists its platform fee by plan on its pricing page, so this guide does not retype it.

Each competitor row is what its own pricing page stated on 14 November 2026. “Not stated” means the page did not mention it.

The twelve scheduling tools, one by one

1. Vonza
Publisher
Best for: Coaches, consultants, tutors and schools who want the booking, the payment, the reminder and the follow-up in the account that also sells their courses and community
The new Vonza Scheduling, which you opt into beside the classic scheduler, offers six meeting types: one-on-one, group sessions with a seat count, round robin, collective, one-off links and meeting polls. Start from 137 templates in 15 categories or describe the meeting in one line and let Vonza AI draft the page (uses AI credits). Each meeting offers up to 12 lengths, each with one of nine price kinds including deposits and session packs, paid by card, Apple Pay, Google Pay or Klarna through Stripe, by PayPal for one-time prices or by Paystack in Nigerian naira. Google and Microsoft calendars are checked for conflicts and receive the bookings, iCloud busy times are read, and every booker becomes a CRM contact that an automation can tag, email, text or enrol in a course.
Vonza is the publisher of this guide. The new Scheduling is opt-in: the account owner turns on New booking pages, and until then bookers see the classic booking page. Text reminders come out of your SMS marketing allowance, deposits, instalments and flexible prices need an eligible plan, and Zoom, Google Meet and Microsoft Teams links depend on the apps being connected. There is no waitlist, no Webex or GoTo link, and no native Zapier app: Zapier, Make and n8n connect through signed webhooks.

How to choose appointment scheduling software

Start with what you book: a meeting, an appointment, a class, or a session that is part of a programme. Then check these, in this order.

What the free plan really allows: Free plans are capped by event types or pages, bookings a month, or seats, and most of them move payments to a paid plan. Count the booking pages, bookings and hosts you need in a busy month before you compare paid prices.
How the paid price is counted: Per seat (Calendly, Cal.com, Zoho, Appointlet, Koalendar), per calendar (Acuity), per location (Square), per bookings a month (SimplyBook.me) or per plan with hosts included (Vonza). A team of five hosts changes the order of the table.
Payments, deposits and fees: If a booking is paid, check the processors, whether deposits, packages and subscriptions are possible, and whether the tool adds its own fee to the processor’s. TidyCal’s 1% below Pro and Square’s processing rates are the two stated here.
Group, class and team booking: A class needs seats per time and a waitlist or a pack to sell; a team needs round robin or collective meetings and a calendar per host. Meeting-link tools and appointment tools split on exactly this line.
Calendars and conflicts: Check which calendars are read for busy times, which receive the booking, and how many connections the plan allows. Several free plans allow one connection; iCloud is often read-only.
Reminders that reach people: Email reminders are standard. SMS is metered, regional or paid separately almost everywhere, so read the credit count and the countries before you count on it.
What happens after the booking: A booker who becomes a contact, gets the right follow-up and can be enrolled or sold the next session saves copying details between tools. Check the native CRM and email connections, or webhooks to Zapier or Make.

How we chose

Every competitor figure comes from the vendor’s own pricing, features or help page, read on 2026-11-14 and saved as plain text; nothing comes from review sites, listicles or memory, and no vendor’s review counts, ratings or user numbers are repeated.
The twelve cover the main ways people book: meeting links (Calendly, Cal.com, Doodle, Appointlet, Koalendar), appointment software for service businesses (Acuity Scheduling, Setmore, SimplyBook.me, Square Appointments), a business-suite scheduler (Zoho Bookings), a lifetime licence (TidyCal) and an all-in-one platform (Vonza). YouCanBookMe, Zeeg, Fresha and Book Like A Boss are left out because their prices could not be read from their own pages, and the course and funnel platforms whose schedulers are tied to another product are left to their own guides.
“Not stated” and “Not listed” mean the page did not mention it, not that the tool lacks it; “not published” means the page gave no figure. Where a page showed only one billing option the other is marked as not readable, and where a page printed inconsistent figures (Setmore, Koalendar) the guide says so rather than choosing one silently.
Vonza is the publisher and appears first with its live price; its row is written from its own product, and no competitor is scored or ranked.

Questions

Answered from the pages we read, with the date we read them.

The one built for what you book. For meeting links, Calendly (a free plan for one event type, Standard $12 per seat a month) or Cal.com (a free plan with no usage limits). For appointments at a service business, Acuity Scheduling (classes, packages and deposits from $20 a month per calendar), Setmore (a free plan for up to 4 users) or Square Appointments (a free booking site with Square payments). For a team on Zoho, Zoho Bookings; for a one-time payment, TidyCal; for polling a group, Doodle. Vonza suits coaches, consultants, tutors and schools who want the booking, the payment and the follow-up in the account that also sells their courses and community.

On the vendors’ own pages, Cal.com’s free plan has unlimited links and calendars and takes Stripe and PayPal payments for one user; Koalendar’s has unlimited bookings and pages; TidyCal’s has unlimited bookings with paid, group and package bookings and a 1% fee; Setmore’s allows up to 4 users with group classes and payments; Square’s is $0 per location with Square processing. Calendly allows one event type, Doodle one poll, one booking page and one 1:1, Appointlet 25 meetings a month for 5 members, and SimplyBook.me 50 bookings a month. Acuity has no free plan. Vonza offers a 14-day free trial on every plan.

A coach books discovery calls, paid sessions and often a group programme, so look for deposits or session packs, a group format, reminders and a path from the booking to the programme. Koalendar and Setmore publish coaching pages and take payments on Pro or on the free plan respectively; Acuity sells packages with payment plans; Calendly and Cal.com cover the call itself. Vonza adds what the standalone tools hand off: the booking page sits in the same account as the course, the community, the email list and the CRM, with deposits, session packs and an automation that enrols the booker.

Cal.com (Stripe and PayPal), TidyCal (Stripe or PayPal, with a 1% platform fee below Pro), Setmore (Square, Stripe and PayPal), Square Appointments (Square is the processor) and SimplyBook.me (payments, deposits and tips listed from the free plan). Calendly, Doodle, Appointlet and Koalendar move payments to a paid plan, Zoho Bookings does not state which plan, and Acuity has no free plan. Every Vonza plan takes payments through Stripe, PayPal or Paystack after the 14-day free trial.

TidyCal states a 1% fee on Stripe payments on its free and lifetime plans and none on Pro. Square Appointments is the processor, so its rates apply: 3.3% + 30¢ online and 2.6% + 15¢ in person on the free plan. SimplyBook.me says it charges no transaction fee of its own. Calendly, Acuity, Cal.com, Zoho Bookings, Setmore, Doodle, Appointlet and Koalendar do not publish a fee on the pages we read, and your processor charges its own fee on every tool. Vonza lists its platform fee by plan on its pricing page.

Round robin is a team-plan feature almost everywhere: Calendly Teams, Cal.com Teams, Zoho Bookings (four algorithms), TidyCal Agency, Doodle Team, Appointlet and Koalendar Pro; Acuity, Setmore, SimplyBook.me and Square do not list it. Group or class booking is the other dividing line: Acuity, Setmore, SimplyBook.me, Square, Zoho, TidyCal, Appointlet and Koalendar sell seats or classes, while Calendly and Doodle offer group and collective meetings or polls. The new Vonza Scheduling has both: group sessions with a seat count, and round robin that shares bookings evenly or to the host with the lightest day.

Acuity lists deposits on every plan, Square Appointments lists appointment deposits, Setmore lists deposits on its features, and SimplyBook.me lists deposits from its free plan. Calendly offers payment links for deposits and one-off fees on paid plans. Cal.com, Zoho Bookings, TidyCal, Doodle, Appointlet and Koalendar do not list deposits on the pages we read. In the new Vonza Scheduling a deposit is one of nine price kinds: part is paid at booking and the balance is charged a set number of days before the meeting, on eligible plans.
