Choosing a booking tool is a decision that will be with you for years. Switching later is heavy: clients get used to the link, data accumulates, flows consolidate. It pays to choose well the first time. We compared the 5 most-used tools in small and medium service businesses with objective criteria. Ranking based on practical use, not hype.
How we evaluated (criteria)
Each tool was tested with the typical independent professional / small business profile (1-5 staff). Criteria:
- Setup: time to working online calendar (zero to first booking).
- Team: managing multiple professionals with own hours and catalogs.
- Reminders: available channels (email, SMS, WhatsApp), no-show effectiveness.
- Billing: issuing documents with tax ID, local fiscal compliance.
- Checkout: mixed payment (cash + card), products, tips.
- Cost: pricing structure, per-booking commissions, free plan.
- Support: language, response time, quality.
- Ecosystem: plugins, integrations, product evolution.
#1 BookHero
BookHero is what we recommend as default for independent professionals and small businesses. Designed for the typical problem: hairdresser, physiotherapist, PT who wants an online calendar, reminders that cut no-shows, simple checkout, local invoicing. No per-booking commissions.
Strengths
- Setup in 10-15 minutes, no tutorial needed.
- WhatsApp reminders on Pro plan - the channel almost every client prefers.
- Multi-staff with auto-assign (random, round robin, least loaded day).
- Local invoicing: informational documents with tax ID, configurable prefixes.
- Robust checkout: split cash + card, one-off products, separated tips.
- No per-booking commission - flat monthly subscription.
- Client cards with private notes, CSV import, phone-based dedup.
- Multi-shop with 1 account managing several businesses.
- Support in PT/EN with human response time.
Limitations
- No native mobile app (responsive web works well, but some prefer installed apps).
- No native two-way Google Calendar integration (only one-way export).
- Packages with automatic session counters don't exist - workaround via products.
- Newer than mature competitors - fewer third-party plugins.
#2 Booksy
Booksy is one of the best-known in barbershops and salons, especially in urban markets. Has a mature mobile app and a marketplace that can bring new clients. The cost is the marketplace commission - 15-25% on bookings captured by Booksy.
Strengths
- Polished mobile app, with 10+ years of iteration.
- Marketplace can capture new clients (visibility).
- Recognized in urban barbershops - clients already have the app installed.
- Mature payment and marketing integrations.
Limitations
- Marketplace commission eats 15-25% of bookings brought by Booksy.
- Limited local invoicing (tax ID, AT rules) - doesn't replace fiscal software.
- Client gets locked to the app - migrating is hard because client knows the Booksy link.
- Portuguese support can be limited in non-priority markets.
- Product profile oriented to large salons - over-featured for soloists.
#3 Treatwell
Treatwell has wide reach in esthetics, spa and mid/high-end hair in Europe. Platform with strong marketing tracking. High dependency - if you switch, you lose presence on the platform.
Strengths
- High reach and visibility in European markets.
- Detailed marketing tracking and analysis.
- Marketplace captures new clients via local searches.
- Established in mid/high-end esthetics and spa.
Limitations
- High marketplace commission (15-30% in some segments).
- Non-local billing - doesn't replace PT fiscal software.
- Platform oriented to marketing, not operations - operations need adding.
- Dependency: presence comes from the platform, not your brand.
- Slower setup, with platform compliance / requirements.
#4 Calendly
Calendly is one of the most elegant in UX, but was designed for B2B professionals (consultants, coaches, salespeople) - not for retail services. Lacks checkout, products, billing, rich team.
Strengths
- Elegant UX, fast setup.
- Useful free plan for B2B soloists.
- Integrations with Zoom, Google Calendar, Microsoft Calendar.
- Solid for professionals charging by consultation hour.
Limitations
- No checkout for in-person payment.
- No products sold (not designed for retail services).
- Local billing not supported (need external fiscal software).
- Multi-staff with different hours/catalogs is limited.
- No WhatsApp reminders.
- Excellent for B2B, weak for barbershop / salon / esthetics.
#5 Setmore
Setmore has a decent free plan for solo professionals. Basic features work, but scaling to 2+ staff or to a local market with fiscal rules is where the limit shows.
Strengths
- Real free plan up to X bookings/month.
- Simple setup, familiar interface.
- Stripe, Square, Zoom integrations.
- Good for solo casual B2C professionals.
Limitations
- Multi-staff in paid plans, with growing friction.
- Local billing not supported (PT/AT, tax-ID rules).
- No native WhatsApp reminders (only SMS / email).
- Limited Portuguese support.
- App and product evolves slowly compared to bigger competitors.

How to choose between them
Define your profile in 1 sentence
I'm X (profession), in Y (city), with Z staff, billing approximately W/month.
Identify your preferred client channel
WhatsApp (PT, ES, BR culture)? Email? SMS? Marketplace? Drives much of the choice.
Evaluate the importance of not losing clients
If clients are used to a marketplace app (Booksy / Treatwell), switching can cost. If you're starting from zero, BookHero wins.
Weigh annual commissions
15-25% commission on 50% of bookings can be €2,000-5,000/year. BookHero subscription is a fraction of that.

Common mistakes when choosing
- Choosing by free plan without evaluating if it scales - migrating later is expensive.
- Not testing with real clients for 2 weeks before deciding.
- Ignoring hidden annual commissions (marketplace) - €5k over 5 years = new car.
- Not checking if local billing is supported - forces extra software later.
- Choosing by isolated feature (X has cool feature Y) without seeing the whole.
FAQ
Can I migrate from one tool to another without losing clients?
Yes, most tools export client CSV. The real challenge is the public link changing - clients used to the old link need notice. We recommend communicating the change with 30 days' notice and keeping the old system in read-only for another 30.
Does marketplace (Booksy / Treatwell) justify the commission?
Depends. If 50%+ of your bookings come from marketplace and you can't replicate the capture, yes. If most bookings are recurring clients who know your name, the commission is wasted. Calculate: marketplace revenue × commission vs alternative marketing cost.
Does Calendly work for barbershops?
No. Calendly was designed for B2B (consultants, coaches). Lacks checkout, products, local billing, robust multi-staff. For barbershops, choose BookHero or Booksy.
Does BookHero work in any country?
Yes, BookHero was designed to be used in any market. Informational invoicing works globally; for specific local fiscal compliance (PT, ES), there's native support.
What's the biggest difference between BookHero and the others?
Combination of native WhatsApp reminders + local billing + no per-booking commission. Other tools have 1 or 2 of these; BookHero combines all three in a coherent product.
