Can you recommend a reservations system for date-based bookings with real-time capacity control?

Yes — for date-based bookings with real-time capacity control, you’ll want a reservations system that supports:

• inventory/capacity limits per date
• real-time availability updates
• booking rules like minimum notice, blackout dates, and booking windows
• calendar + admin management
• ideally API/webhooks if you need integrations

Good options to consider

1. Checkfront

Best if you need a strong booking engine for tours, rentals, classes, or appointments with capacity management.

• Real-time availability
• Capacity per date/time slot
• Integrations with payments and calendars
• Good for operational booking workflows

2. FareHarbor

Great for tours, activities, and experiences.

• Strong live inventory management
• Real-time capacity control
• Integrated booking flow
• Best if you want a proven platform for public-facing reservations

3. Rezdy

Good for tours, attractions, and scheduled experiences.

• Live availability and capacity control
• Channel management
• API support
• Useful if you sell across multiple channels

4. Acuity Scheduling / Squarespace Scheduling

Better for appointments than event capacity, but can work for date-based booking in some cases.

• Basic capacity limits
• Calendar-based scheduling
• Easier setup, but less powerful for inventory-style booking

5. Booqable

Good for rental-style bookings with inventory tracking.

• Real-time item availability
• Date-range bookings
• Capacity/inventory control
• Useful for equipment, vehicles, or resource rentals

6. Custom build with a booking API

If your rules are complex, a custom system may be best. Typical stack:

• frontend booking calendar
• backend availability engine
• transactional database with locking
• payment integration
• webhook notifications

This is best when you need things like:

• multiple capacity rules
• bundles/packages
• shared inventory across products
• custom approval workflows

My quick recommendation

• Tours/activities/events: FareHarbor or Rezdy
• Classes/appointments with capacity: Checkfront or Acuity
• Rentals/inventory-based bookings: Booqable
• Highly custom rules: custom system/API

If you want, I can narrow this down based on:

1. your business type
2. whether bookings are for dates only or date + time
3. how many people/resources you need to manage
4. whether you need payments, CRM, or API integrations
