The advertised price of a booking system is rarely the actual price you pay. Monthly fees are just the start — commissions, payment processing, add-on charges, and hidden costs can triple your total spend.
This guide breaks down what booking systems actually cost in 2026, with specific numbers for different business sizes. Use it to calculate your true cost before committing.
The 4 Types of Booking System Pricing
Every booking platform uses one (or a combination) of these pricing models:
1. Flat Monthly Fee (No Commission)
You pay a fixed monthly amount regardless of how many bookings you receive.
Examples: HoneyBook ($19-$79/month), Acuity ($16-$49/month), Addagio Pro ($29/month)
Best for: Businesses with consistent, predictable booking volume. The more bookings you get, the lower your per-booking cost.
2. Commission Per Booking (No Monthly Fee)
You pay nothing upfront but give a percentage of each booking to the platform.
Examples: Addagio Free (5%), Fresha (20% on new clients), Airbnb (15-17% combined fees)
Best for: New businesses with low or unpredictable volume. You only pay when you earn.
3. Freemium (Limited Free + Paid Upgrades)
Basic features are free, but you pay to unlock advanced features.
Examples: Calendly (free for 1 event type, $10-$16 for more), Setmore (free basic, $12+ for premium)
Best for: Solo operators with minimal needs who may upgrade later.
4. Marketplace Model (Commission on Discovery)
The platform helps clients find you but charges a commission on those marketplace-acquired bookings.
Examples: Fresha (20% on marketplace leads), Booksy (marketplace commission), Airbnb (15-17%)
Best for: Businesses that need client discovery, not just scheduling.

Growing Business: 80 Bookings/Month, $100 Average
| Platform | Monthly Cost | Annual Cost |
|---|---|---|
| Addagio Free | $400 commission + $256 processing | $7,872 |
| Addagio Pro | $29 + $256 processing | $3,420 |
| HoneyBook Premium | $79 + $256 processing | $4,020 |
| Fresha (50% marketplace) | $800 commission + $183 processing | $11,796 |
Winner: Addagio Pro. At 80 bookings/month, the flat $29 fee plus zero commission saves thousands compared to percentage-based pricing.
Multi-Staff Business: 200 Bookings/Month, $120 Average
| Platform | Monthly Cost | Annual Cost |
|---|---|---|
| Addagio Pro | $29 + $744 processing | $9,276 |
| Square Appointments (Premium) | $69 + $650 processing | $8,628 |
| HoneyBook Premium | $79 + $744 processing | $9,876 |
| Acuity (Powerhouse) | $49 + $744 processing | $9,516 |
Winner: Tight race. Square wins on raw cost (lower processing fees), but Addagio and Acuity offer better booking experiences. Choose based on features, not just price.
Hidden Costs Most Platforms Do Not Advertise
1. Payment Processing Fees
Every platform that accepts payments charges processing fees on top of their own fees. This is unavoidable — Stripe, Square, and PayPal all charge 2.5-3.5%.
Annual cost on $48,000 in bookings: $1,400-$1,700 in processing fees alone.
2. SMS/Text Reminders
Some platforms charge extra for SMS reminders:
- •Acuity: Included in paid plans
- •Calendly: Not available on free plan
- •Some platforms: $0.01-$0.05 per SMS
At 80 bookings/month with 2 reminders each, that could be $19-$96/year extra.
3. Add-On Features
- •Custom domain: $5-$20/month extra on some platforms
- •Remove branding: Often requires highest-tier plan
- •Additional staff: $10-$30/month per team member
- •Advanced integrations: Zapier/API access locked to premium tiers
- •Priority support: Requires premium plan on most platforms
4. Switching Costs
The biggest hidden cost is switching later. Once you have 500+ clients booked through a platform, migrating is painful. Choose a platform you can grow with.
The Break-Even Calculation: When to Switch from Free to Paid
If you are on Addagio's free plan (5% commission), here is when upgrading to Pro ($29/month, 0% commission) saves money:
Break-even point: $29 / 0.05 = $580/month in bookings
- •Below $580/month in bookings: Free plan costs less
- •Above $580/month in bookings: Pro plan costs less
- •At $2,000/month in bookings: Pro saves you $71/month ($852/year)
- •At $5,000/month in bookings: Pro saves you $221/month ($2,652/year)
This same logic applies to any commission vs. flat-fee comparison. Calculate your monthly booking volume and do the math.
FAQ
What is the cheapest booking system overall?
For zero bookings: Addagio Free, Calendly Free, and Fresha are all $0. For high volume (100+ bookings/month), Addagio Pro at $29/month with 0% commission is typically the lowest total cost. See our full [pricing breakdown](/pricing).
Are there any truly free booking systems with no catch?
Calendly's free plan is genuinely free for 1 event type with no payment collection. Addagio's free plan charges 5% only when you get paid — if you earn nothing, you pay nothing. Fresha is free for existing clients but charges 20% on marketplace-acquired clients.
Should I choose flat-fee or commission-based pricing?
Commission-based (like Addagio Free at 5%) is better when you are starting out and have unpredictable volume. Flat-fee (like Addagio Pro at $29/month) is better once you consistently earn over $580/month in bookings.
Do I need to pay for a booking system AND a website?
No. Booking platforms like Addagio give you a standalone booking page with its own URL. You do not need a separate website. If you already have a website, you can embed or link to your booking page from it. Read our guide on [how to add booking to your website](/blog/how-to-add-booking-to-website).
