The mismatch before the price
Most booking-software comparisons run the same four columns: monthly cost, booking limit, client limit, free trial. None of them tell you whether the tool's data model can actually represent the business you intend to run. A yoga studio owner wanting to manage six instructors and group classes of up to twelve clients opens Calendly — the most-recognised name in the category — and runs into a wall. Not a paywall. Not a tier limit. Something prior to both: there is no staff entity in Calendly's data model, no group capacity, no deposit logic tied to a cancellation policy. Adding a paid seat does not change that architecture.
This guide groups the alternatives by the primitive the software is built around. That question comes before price, because a tool built around one person's calendar cannot run a five-chair salon at any price.
One entry — Reservo — is a multi-tenant booking and appointment-management SaaS sold once as source code. You deploy it under your own brand and operate it as the platform service businesses subscribe to — multi-staff scheduling, deposits, automated email reminders. Reservo belongs in the staff-roster group below, supports group-mode classes with configurable capacity, and explicitly cannot handle bookable rooms, courts, or equipment: no resources table shipped in v1. This guide covers all four groups and places each tool in the right one.
Four questions worth settling before you look at pricing
1. Is the job scheduling people's time, or managing a physical space? A staff-roster tool assigns services to practitioners and computes availability from their working hours. A resource tool tracks a court, a room, or a desk and lets clients reserve blocks of it. These are different data models, and most tools in this guide do only one.
2. Does the business bring its own clients, or does the software source them? A booking system manages existing clients. A marketplace brings new clients through a consumer directory — and switching does not transfer that demand.
3. Is the buyer a business managing its own appointments, or an operator who wants to own a booking platform? Group B rental tools are the right starting point for a business. Only one entry in this guide ships as a codebase with a commercial licence for operator use.
4. How many people take bookings — and will that number grow? Most Group B tools meter on staff in some form. The per-seat cliff engages at exactly the moment a business is already spending on hiring, and understanding which ceiling applies to actual usage matters more than the headline monthly figure.
The alternatives, by primitive
Group A — One-person calendar
These tools are built around one person's availability: compute a free slot, share a link, confirm the booking. The correct primitive for an individual consultant, a solo photographer, or a professional scheduling calls. They are the wrong answer for any business with multiple practitioners sharing a booking calendar, because the data model has no concept of staff entities with their own services and working hours.
Calendly — Free; Standard $10/seat/month; Teams $16/seat/month (annual); Enterprise from $15,000/year
Calendly is the most-used meeting-scheduling tool in this category. Its core job — sharing availability, collecting a booking, routing to a conferencing link — it does better than anything in this guide: deep integrations with Zoom, Meet, and Teams; routing forms; round-robin scheduling; a large integration catalogue. Pricing as of 2026-08-07 (calendly.com/pricing).
What Calendly does that Group B tools do not: conferencing integrations, routing forms, and round-robin assignment are genuinely Calendly's domain and exceed what any staff-roster tool offers for those specific jobs.
Honest limit: Calendly's primitive is one calendar. There is no concept of services offered by a staff member, no deposit logic, no multi-practitioner availability model. A five-chair barbershop cannot run its staff roster on Calendly at any plan tier.
Acuity Scheduling — Starter $16–20/month (1 calendar); Growing $27–34/month (up to 6 calendars); Powerhouse $49–61/month (up to 36 calendars)
Acuity is the Group A tool that sits closest to Group B. It supports intake forms as a first-class feature, packages, subscriptions, and gift certificates, and runs under the Squarespace brand. It meters on calendars — which maps to practitioners — rather than explicitly on staff seats, but the effect is the same. Pricing as of 2026-08-07 (acuityscheduling.com/pricing).
What Acuity does that most Group B tools do not: mature intake form capabilities, packages and gift certificates, and deep Squarespace ecosystem integration.
Honest limit: Acuity is built around independent calendar units, not a shared multi-staff booking model. For a business where practitioners share services and staff need a unified view across the day, it is working against its own data model's grain.
Group B — Staff roster
These tools are built around a staff entity: services are assigned to practitioners, availability is computed per staff member, and a booking claims a slot in a specific person's schedule. The correct primitive for salons, barbershops, spas, tattoo shops, massage studios, nail techs, and similar appointment-based service businesses. The economics of this group are dominated by per-practitioner metering in some form.
Booksy — $29.99/month base + $20/month per additional user
Booksy is the highest-recognition staff-roster platform in the personal-care category. A two-staff shop runs approximately $49.99/month; a five-staff shop approximately $109.99/month, before processing fees (as of 2026-08-07, biz.booksy.com/pricing). Booksy also operates a consumer-facing discovery marketplace that generates new-client bookings through the Booksy app — this is its clearest advantage over every other entry in this group.
What Booksy does that Group B alternatives do not: consumer marketplace bringing new-client bookings; mature native mobile apps for staff and clients; built-in payment processing and card readers; point-of-sale and retail inventory. A business switching from Booksy does not carry its marketplace demand along. For businesses that rely on that new-client flow, this is the real cost of switching.
Honest limit at the operator level: Booksy is sold to the salon. You cannot purchase it to operate as your own platform for others. The per-staff meter is a vendor revenue structure you subscribe to, not one you design.
Fresha — Paid plans; structure: Independent (flat) / Team (per bookable team member) / Enterprise (custom)
Fresha's free-to-the-business plan was retired: paid tiers now apply, with the Team tier priced per bookable team member. The transition happened with approximately one month's notice, starting approximately 2025-08-01 (as of 2026-08-07, fresha.com/pricing — HIGH confidence on structure; USD figures not cited as the official page geo-localises to local currency). Fresha operates a consumer marketplace similar to Booksy with integrated payment processing.
What Fresha does that Group B alternatives do not: consumer marketplace client acquisition; integrated payments; deeper retail inventory and point-of-sale; established consumer brand trust in beauty and wellness.
Honest limit: The free tier ended with one month's notice. Fresha is a subscription platform — the pricing terms belong to Fresha and have already changed once.
Square Appointments — Free (solo, card processing only); Plus approximately $29–49/month per location (figures conflict across sources)
Square Appointments is the booking module inside the Square payments and POS ecosystem. Its metering axis differs from every other tool in this group: it charges per location, not per staff member. A single-location shop with multiple staff may find the per-location model more economical than Booksy's per-user meter. The free solo tier is real: one staff member, one location, no monthly fee — only card processing. Pricing as of 2026-08-07 (official page renders client-side; figures from Forbes Advisor — one source reports $29/month, another $49/month for Plus; verify directly before budgeting).
What Square does that Group B alternatives do not: the full Square POS and hardware ecosystem — card readers, payroll, team management, and inventory all integrated. For a business already on Square for payments, the ecosystem coherence is a real switching-cost argument.
Honest limit: Square Appointments is a subscription, not a codebase. It cannot be purchased to operate as a platform for other businesses.
Setmore — Free: up to 4 users, 200 appointments/month; Pro: approximately $5/user/month (annual)
Setmore is the honest first answer for the small end of this market. Its free tier covers four users and two hundred appointments per month — real capability for a two- or three-person shop running moderate volume, at no cost. Pricing as of 2026-08-07 (setmore.com; MEDIUM confidence from aggregator sources — re-verify directly before budgeting).
What Setmore does that makes it the honest concession: four-user, 200-booking/month coverage with no financial commitment. Inside those limits, no other tool in this guide beats it on entry cost.
Honest limit: Setmore is a subscription you use, not a platform you own. The free tier exists because the commercial product begins above it.
Easy!Appointments — $0, GPLv3
Easy!Appointments is the self-hosted staff-roster booking system. GPLv3 — more permissive than what Reservo ships under — and costs nothing in software fees. Actively maintained: last stable release 1.6.0, dated 2025-05-27 (as of 2026-08-07, github.com/alextselegidis/easyappointments/releases). Stack: PHP 8.2+, CodeIgniter, MySQL. For a single business wanting to self-host booking for its own use on a stack it can extend: a credible and cost-free option.
What Easy!Appointments does that Reservo does not: GPLv3 licence with no commercial-use restrictions on self-hosted installs used for the operator's own business; zero software cost; maximum licence freedom for a developer comfortable with PHP/MySQL.
Honest limit: One install serves one business. There is no multi-tenant model, no org isolation, no plan system. Building multi-tenancy on top is a genuine engineering project.
Reservo — $249, one-time purchase
Reservo is the only entry in this group sold as a codebase. You purchase it once at $249, deploy it under your own brand, and operate it as the platform your tenants — service businesses — subscribe to. Each tenant gets isolated availability rules, deposit policies, customer records, and a public booking page. You set the plan structure; whatever per-seat fee you charge your tenants flows to you, not to a vendor. The slot reservation path prevents double-bookings under concurrent requests through a single atomic database function. Group-mode services — where multiple clients book against the same time slot up to a configured capacity — are supported and enforced atomically at the reservation layer.
Reservo belongs in this group, not Group C. Its booking engine is keyed to staff members: services are assigned to staff, availability is per-staff, and the slot reservation writes against a staff user ID. There is no resource entity in the v1 schema — courts, rooms, desks, and equipment are outside what Reservo can model at any plan tier.
What Reservo does not ship in v1: consumer marketplace or new-client discovery directory; native mobile apps; SMS reminders (email only in v1; Twilio is v2 roadmap); two-way calendar sync (read-only iCal overlay in v1; Google and Microsoft OAuth sync is roadmap); POS or inventory. For a service business that needs any of those from day one, the rental tools above are the correct answer.

Group C — Bookable resource
These tools are built around a resource entity — a court, a room, a desk — rather than a staff member. Availability is tracked against the resource. This is the correct primitive for space-booking, and Reservo has no position in this group: there is no resource entity in the v1 schema, which is a scope decision, not a configuration gap.
Skedda — approximately $99/month at 15 spaces; approximately $199/month at 25 spaces (annual, MEDIUM confidence — aggregator-sourced, Capterra 2026-08-07; verify directly at skedda.com)
Skedda is a purpose-built space-booking management platform. A community centre managing tennis courts, a coworking space handling hot-desk reservations, or a recording studio booking its rooms is correctly served here. Pricing is per-space tier rather than per-staff, because the staff member is not the bottleneck.
What Skedda does that no Group B tool does: it models the bookable resource, not the practitioner. That is the architecturally correct primitive for space management.
Honest limit: Skedda is not the right tool for a business whose constraint is practitioner availability. It cannot substitute for Group B, and Group B tools — including Reservo — cannot substitute for it.
Group D — Marketplace listing
Some platforms in this category are not primarily booking systems. They are consumer discovery platforms that include booking as a feature. The primitive is a marketplace listing: the tool brings demand by exposing businesses to a directory that consumers search. Booksy spans Group B (staff-roster booking system) and this group (consumer discovery). Platforms like Vagaro and StyleSeat operate similarly.
The critical distinction: records export; marketplace demand does not. For businesses that depend on platform-sourced new-client flow, Group D platforms are the correct category — this guide names that honestly. Reservo is a booking system, not a marketplace.
How to choose
| If the job is... | The right group and entry |
|---|---|
| Scheduling individual meetings, calls, or consultations for one person | Group A — Calendly (Free or Standard) |
| A solo or small independent practitioner needing intake forms, packages, or gift certificates | Group A — Acuity Scheduling |
| A service business with 1–4 staff, modest volume, no budget commitment | Group B — Setmore Free (4 users, 200 bookings/month) |
| A service business already running on Square's payment and POS ecosystem | Group B — Square Appointments (free solo; Plus ~$29–49/mo per location — verify) |
| A service business that relies on new-client discovery through the platform | Group B + D — Booksy or Fresha (marketplace demand; accept per-member pricing) |
| Self-hosting booking for a single business, maximum licence freedom, PHP/MySQL stack | Group B — Easy!Appointments (GPLv3, $0) |
| Managing bookable physical spaces — rooms, courts, desks, studios | Group C — Skedda |
| Owning and operating a staff-roster booking platform as a business for other businesses | Group B — Reservo ($249 one-time; multi-tenant; commercial licence) |
The clearest boundary is the last row. Every entry above it is a tool a service business buys to use. The last row is the tool an operator buys to own. None of the tools above the last row are available to purchase and operate as a platform for others: Booksy, Fresha, Square, Setmore, Acuity, Calendly, and Skedda are all subscriptions. Easy!Appointments is GPLv3 and free, but is a single-tenant install per business. Reservo is the only tool in this guide sold as a multi-tenant platform codebase for operator use.
Honest verdict
For the service business owner looking for software to manage its own bookings: this guide does not end at Reservo. Setmore Free is the honest starting point for a 1–4 person shop under two hundred bookings a month. Square Appointments covers the business embedded in the Square ecosystem. Booksy and Fresha are the honest answer when new-client discovery from a consumer marketplace is what the business is actually buying — and no amount of feature comparison changes that. Easy!Appointments is the right call for a developer who wants GPLv3 freedom on a PHP/MySQL stack.
Reservo earns its place in this guide at the operator layer — the buyer who wants to own and run the platform rather than subscribe to someone else's. At that intersection, every other tool in this guide is the wrong category of purchase: not because of price, but because of what they are. A subscription to a booking platform is a different transaction from a multi-tenant codebase you deploy under your brand, price yourself, and control.
If you want to run the booking platform: Group B's last entry. If you want booking software for your own salon: start at Setmore.
Common questions
What is the difference between a meeting-scheduling tool and a booking system for service businesses?
Meeting-scheduling tools — Calendly and Acuity at their entry points — are built around one person's calendar. Service-business booking systems are built around a staff roster: services assigned to practitioners, availability per-staff member, bookings claiming specific slots with deposit and policy logic attached. These are different data models. A meeting tool cannot run a multi-practitioner salon's staff roster at any price. Reservo is a staff-roster system — slot computation is per-staff, deposit logic is per-service, and the multi-tenant architecture is built for appointment-based service businesses.
Which booking software in this category does not charge per staff member?
Setmore's free plan covers up to four users and two hundred appointments per month at no charge. Square Appointments meters per location rather than per staff, which can favour a single high-staff-count site. Easy!Appointments is GPLv3 at $0 with no staff or booking limits in the codebase. Reservo charges $249 once to the operator who purchases it — there is no ongoing per-seat fee from the vendor. The operator then designs their own tenant plan structure; whether tenants pay per staff is a pricing decision the operator makes. Booksy ($29.99/month + $20/month per additional user), Fresha (per-bookable-team-member tier), and Acuity (per calendar) all meter on practitioners in some form.
What is the difference between Booksy and Setmore for a small service business?
Booksy operates a consumer-facing marketplace that generates new client bookings through the Booksy app — clients discover businesses through the platform's directory, not only through the business's own channels. Setmore does not have this. Booksy: $29.99/month base + $20/month per additional user (as of 2026-08-07, biz.booksy.com/pricing). Setmore: free for four users and two hundred bookings per month; Pro approximately $5/user/month annual (as of 2026-08-07, setmore.com — aggregator-sourced, MEDIUM confidence). For a shop bringing its own clients, Setmore Free may be sufficient. For a shop relying on a discovery marketplace, Booksy's consumer directory is the honest reason to stay. Reservo is what an operator deploys to run the booking platform those businesses subscribe to.
What booking software handles group classes where multiple clients book the same time slot?
Group-class booking — multiple clients claiming the same slot up to a capacity ceiling — falls within the staff-roster category, Group B. Booksy, Fresha, and Square Appointments all support some form of group service. Reservo explicitly supports group-mode services with a configurable maximum concurrent capacity, enforced atomically at the reservation layer; a booking that would exceed capacity is rejected. What Reservo does not include in v1: membership packs, recurring class series, or check-in tracking. Platforms built for the fitness market — Mindbody and TeamUp — handle those membership economics and exist outside the alternatives sourced in this guide. Group B tools including Reservo cover the slot capacity mechanics; they do not cover the membership business model.
What happens to client records and bookings if a booking platform changes its pricing?
Fresha's 2025 transition is the live case study: businesses received approximately one month's notice before paid subscriptions replaced the free tier, effective approximately 2025-08-01 (as of 2026-08-07, fresha.com/pricing). Booking records typically export. Marketplace demand — clients who found the business through the platform's consumer directory — does not. For tools without a marketplace layer (Setmore, Square Appointments, Easy!Appointments), data portability is straightforward because there is no platform-sourced demand to preserve alongside the records. Reservo stores all booking data, customer records, and tenant configuration in a database the operator controls. There is no ongoing subscription, so a vendor pricing change is not applicable to an operator who has purchased the codebase.
