Quick answer
The best scheduling software for a small business depends on what the tool bills by. As of October 2026, one person can book free with Calendly, Cal.com or TidyCal, Setmore is free for up to 4 users, and Square Appointments is free per location with unlimited staff calendars. Paid plans start at $5 per user a month, billed annually.
Key takeaways
- Look at the billing unit before the feature list: Calendly and Cal.com bill per seat or user, Setmore per staff calendar, Acuity by calendar tier, Square Appointments per location.
- One person booking calls does not need a paid plan. Calendly, Cal.com and TidyCal each publish a free plan, and a personal Google account can create a single booking page.
- For a team at one location, Square's flat $49 a month Plus plan costs less than 5 Calendly Standard seats at $10 each billed yearly, as of October 2026.
- Text reminders are where free plans often stop: Setmore and Acuity list them on paid plans only, while Square lists text and email reminders on every plan.
- If you take deposits or sell packages, check payments first. Microsoft states there is no payment support in Bookings, and Google requires an eligible Workspace subscription plus Stripe.
What is the best scheduling software for a small business?
There is no single best scheduling software for a small business; the right one is the tool whose billing unit matches the shape of your business. Booking tools charge like parking lots: some by the car, some by the space, some by the lot. Count what you have before you compare features.
Use this rule first:
- One person booking calls: a free booking link is enough. Calendly, Cal.com and TidyCal each publish a free plan, and a personal Google account can create one booking page.
- Several staff or rooms: pick by how the tool prices extra calendars. Per-seat tools get expensive as you add people, while Square Appointments charges per location with unlimited staff calendars.
- You take deposits or sell packages: pick by payment features, and check whether Google Calendar appointment schedules, which you may already pay for, covers it.

How do the main booking tools compare on price and limits?
As of October 2026, five of these eight tools publish a free plan, and the lowest paid price is Setmore Pro at $5 per user a month, billed annually. Every entry was read on the vendor's own page that month.
| Tool | Bills by | Free plan | First paid price | Calendars or staff |
|---|---|---|---|---|
| Calendly | Seat | Yes: one event type, one calendar connection | Standard, $10 per seat a month, billed yearly | A seat for each person who connects a calendar and hosts |
| Cal.com | User | Yes: 1 user, unlimited event types and calendars | Teams, $12 per user a month, billed yearly | Free covers 1 user; teams pay per user |
| Setmore | User (each staff calendar counts) | Yes: up to 4 users | Pro, $5 per user a month, billed annually | Unlimited users on Pro |
| Acuity Scheduling | Calendar tier | No; 7-day trial | Starter, $16 a month paid annually or $20 paid monthly | 1 calendar on Starter; up to 6 on Standard; up to 36 on Premium |
| Square Appointments | Location | Yes: $0 a month per location | Plus, $49 a month per location | Unlimited staff calendars on every plan |
| TidyCal | Account (one-time or subscription) | Yes: unlimited bookings, 1 calendar connection | Individual Lifetime, $29 one time; Pro, $12 a month | Team booking page from Agency Lifetime, $79 one time |
| Google Calendar appointment schedules | Google account or Workspace plan | Personal Google account: a single booking page | Premium features need an eligible Workspace or Google One plan; no price on Google's help pages | Up to 20 co-hosts on Business Standard and higher; no resource calendars |
| Microsoft Bookings | Microsoft 365 license | No; not sold as a standalone app | Included in Microsoft 365 Business Basic, $7.00 per user a month, paid yearly | Staff are added to a Bookings calendar |
Three details change the math. Setmore states that each staff calendar counts as a user even when that person has no login. Acuity's Standard plan is $27 a month paid annually and Premium is $49, so the price moves with the tier, not with each added person. Square states that the monthly fee on Plus and Premium applies to each location you run.
How do they compare on reminders, payments, forms and calendar sync?
Text reminders and payment features are where the plans split: several tools hold one or both back for paid tiers. "Not stated" means the vendor's page does not say, so ask before you rely on it.
| Tool | Text reminders | Payments at booking | Intake forms | Google and Outlook sync |
|---|---|---|---|---|
| Calendly | Reminders from Standard; the pricing page does not say whether texts are included | Stripe and PayPal from Standard, including prepaid meeting packages | Lead-routing forms from Teams ($16 per seat) | Google, Outlook and Office 365 |
| Cal.com | Email and SMS notifications listed on Free | Stripe and PayPal listed on Free | Custom booking questions | Google, Outlook and Apple |
| Setmore | Pro only; 500 SMS credits a month per Pro team member | Online payments on Free; deposits on Pro only | Not stated | 2-way calendar sync on Pro only |
| Acuity Scheduling | From Standard | Stripe, Square, PayPal or Venmo on every plan; packages and memberships from Standard | Custom client forms on every plan | Two-way with Google, Outlook, iCloud and Office 365 |
| Square Appointments | Text and email reminders on every plan | Deposits and prepayments on every plan; classes and packages from Plus | Not stated | Google Calendar on Plus and Premium; Outlook not listed |
| TidyCal | Agency Lifetime: 10 per month; Pro: unlimited; US and Canadian numbers only | Stripe and PayPal on every plan; 1% platform fee except on Pro | Not stated | Google, Office 365 and Apple on every plan |
| Google Calendar appointment schedules | None described; email only, up to 5 reminders, wording not editable | Stripe, with an eligible Workspace plan | Booking form with fields you add | Google Calendar |
| Microsoft Bookings | SMS to US, Canada and UK numbers; Microsoft says SMS for virtual appointments is part of Teams Premium | None; Microsoft states there is no payment support | Custom fields on a service | Outlook |
Square and TidyCal payments also carry card processing fees. Recheck every cell on the vendor's page before you buy, because plans change.
When does a per-seat plan cost more than a flat one?
A per-seat plan costs more than Square's flat $49 Plus plan from the fifth seat at Calendly or Cal.com and from the tenth user at Setmore, using the prices each vendor lists as of October 2026. Here is the arithmetic for one location:
- Calendly Standard at $10 per seat: 4 × $10 is under $49; 5 × $10 is over.
- Cal.com Teams at $12 per user: 4 × $12 is under $49; 5 × $12 is over.
- Setmore Pro at $5 per user: 9 × $5 is under $49; 10 × $5 is over.
The same check works against Acuity's tiers. Setmore Pro stays under Acuity Standard's $27 through five users (5 × $5) and passes it at six (6 × $5), the most calendars Standard allows.
This break-even compares price only, and it does not hold in three cases. A second location doubles the Square fee. The per-seat prices are annual-billing rates. And if a free tier covers you, none of it matters: Setmore is free for up to 4 users and Square is $0 per location, though Square lists Google Calendar sync and packages only from Plus.
Rooms are a separate question. Square lists resource management, which assigns rooms, chairs and stations to services, only on Premium at $149 a month per location. Google states that you cannot add appointments to resource calendars.
Do Google Calendar or Microsoft Bookings already cover it?
Google Calendar or Microsoft Bookings already cover basic booking if your business pays for the right plan, but each has a hard gap: Google's help pages describe email reminders only, and Bookings takes no payments.
Google says a personal Google account or a Workspace Business Starter plan gets a single booking page. More than one schedule and automatic email reminders need an eligible Workspace or Google One plan; paid appointments need an eligible Workspace plan. Payments run through your own Stripe account, and Google states that Calendar does not charge platform fees. Two limits: you cannot create a schedule in the mobile app, and co-host calendars are not checked for conflicts by default.
Microsoft lists Bookings as available with Microsoft 365 Business Basic, Standard and Premium, and it requires Outlook on the web. Its FAQ answers the payment question in one line: there is no payment support in Bookings.
When is none of these the right tool?
None of these fits well when your customers book by phone, or when the problem is no-shows and not booking. A booking link only helps people who click links. If most of your appointments start as a call, look at an AI phone answering service that books into your calendar.
If people book fine and then do not show up, fix reminders before you switch tools. The guide to appointment reminder software covers that.
Health practices have one more check. Acuity lists a signed BAA for HIPAA compliance only on its Premium plan. Confirm this in writing with any vendor before patient data goes in.

Your next step
Run the billing-unit count before you open a pricing page.
- Count what you have. Write down the people who take appointments, your locations, and any rooms or equipment that get booked.
- Decide on money. Note whether you need deposits, prepayment or packages at the moment of booking.
- Check what you already pay for. Look at your Google Workspace or Microsoft 365 plan and test its booking page first.
- Shortlist two tools. Match your count to the "Bills by" column, then recheck both prices on the vendors' own pages.
