How Much Does an Online Booking System Cost?

Online booking system costs for small businesses: free tiers, per-user plans, commission models, SMS fees and payment charges. How to choose without overpaying.

How Much Does an Online Booking System Cost?

Short answer: Online booking tools range from free basic plans to monthly subscriptions that scale by staff member or location. Some marketplace platforms charge commission on new clients instead. Extras like SMS reminders and card payments add to the cost. Compare total cost based on your team size and booking volume, and check current pricing on each provider.

The main pricing models

Free plans

Calendly, Square Appointments and others have free tiers with limits on staff, features or branding. Great for sole traders starting out.

Per staff member

Many systems for salons, clinics and trainers charge per bookable person each month. Costs rise as your team grows.

Flat monthly fee

One price for the business, sometimes with booking or staff caps.

Commission or marketplace model

Some platforms list your business in their consumer app and charge a commission on bookings from new clients they send you. Read terms carefully, as fees can be significant on high-value services.

Extras that add up

  • SMS reminders: often charged per message or in bundles. Email reminders are usually free.
  • Payment processing: card fees on deposits and prepayments.
  • Branding removal: some free plans show the provider's logo.
  • Integrations: calendar sync, accounting, marketing tools may need a higher tier.
  • Hardware: card readers if you also take payment in person.

Match the tool to your business

Sole traders and consultants

A simple scheduling link that syncs with your calendar is often enough. Free or low-cost plans work well.

Salons, barbers and beauty

Look for staff calendars, service durations, deposits and no-show protection. Industry-specific tools often justify their cost through fewer missed appointments.

Clinics and therapists

Consider intake forms, notes and data protection. Health data rules may apply. General information, not legal advice.

Trades

Trades often need quote requests rather than fixed time slots. A good enquiry form or job management software may suit better than a calendar.

Do deposits pay for themselves?

For appointment businesses, no-shows are expensive. Taking a deposit or card details at booking often reduces them sharply. A booking system that cuts even a few no-shows a month can more than cover its subscription.

Adding booking to your website

Most systems give you a link or an embed code. You can add a "Book now" button to every page, embed the calendar on a booking page, or both. Keep the button visible on mobile. See how to add online booking to your website.

SiteDrum sites integrate with popular booking tools, and our team adds the button for you as part of your plan.

Questions to ask before you commit

  1. What will it cost with my current team, and if I add two more staff?
  2. Are SMS reminders included or extra?
  3. Can I take deposits, and what are the card fees?
  4. Can I export my client list if I leave?
  5. Does it work smoothly on mobile for customers?

The bottom line

The right booking system can cost little and save a lot. Start on a free or entry plan, add deposits if no-shows hurt, and watch per-staff and SMS fees as you grow.
