What it does
CS-Cart has no booking engine, so services and rentals are sold as stock items and the dates are sorted out by e-mail. This add-on adds two booking types: time slots for appointments, classes and tours, and date ranges per night or day for rentals and stays. Opening hours, exceptions, capacity, resources such as staff or rooms, per-person prices and price rules live on the product. For salons, studios, tour operators, rental shops, small hotels and booking marketplaces.
How it works
On the Booking tab of a product, choose time slots or date ranges, set hours, capacity, guests and prices. The product page shows a calendar with free days and times; the customer picks a slot or a stay, sees the total and books through the cart and checkout. The booking appears on the order, in e-mails with an .ics file and in Orders, Bookings, where you move, cancel or add bookings. Reminders go out before the start. Vendors manage their own bookings.

Tested on Multi-Vendor 4.17.2, CS-Cart 4.17.2. First release.
Can two customers book the last place at the same time?
No. The places are held while each customer checks out, and the capacity is checked again inside a database lock when the order is placed. The second customer is asked to choose another time.
Which time zone are the times in?
The store time zone (Settings > Appearance > Time zone). Customers see the times as the store sees them, and daylight saving changes are handled.
A customer paid late and the places were already taken. What happens?
The payment is never refused. The booking is marked Overbooked in Orders > Bookings (status filter "Overbooked") and, when the status is changed in the admin panel, a notice is shown. Move one of the bookings or cancel it.
Do bookable products use stock?
No. Saving a bookable product switches its inventory tracking off; the capacity comes from the booking settings.
Can customers book several places or people in one booking?
Yes: either Places per booking at most (for example 3 kayaks) or Price per person with adults and children. One booking is one cart line with quantity 1 and the total price.
Can I take deposits?
Not with this add-on: the booking is paid with the order as usual. Use a deposit or partial payment solution if you need one.
Can customers move a booking themselves?
Not in this version. They can cancel within your cancellation window and book again; you can move bookings on the booking page.
Does it work with full page cache and with my theme?
Yes. The product page is the same for every visitor; availability and prices load separately. The picker uses its own scoped styles and works with Responsive, Bright, Nova and themes based on them.
Can vendors manage their own bookings?
Yes, when Vendors manage their bookings is on: their products' Booking tab, their bookings, manual bookings, blocked times and resources.
What happens if the license lapses?
Without a valid license (no key after the 14-day start period, an invalid or revoked key, a domain the license does not cover, or no successful check for 14 days), no new bookings can be made: bookable products show that online booking is unavailable and cannot be added to the cart, and manual bookings are disabled. Existing bookings, the calendar, lists, exports, cancellations, reminders and the customers' My bookings page keep working. Once the license is valid again, booking is possible again.
The admin panel shows a license notice.
Open Add-ons → Manage add-ons → Bookings & Reservations → Settings → License. The status line says what is wrong: no key, a key for another add-on, a revoked license, or a domain that the license does not cover. Fix it and click Check now. See License.
Does the add-on work on my staging copy?
Yes. Subdomains of your licensed domain (for example staging.yourstore.com) and local development hosts (localhost, private IP addresses, .local, .test) are covered by the same license.
Does the license check slow down my storefront or checkout?
No. The check runs in the admin panel or from cron, once a day. The storefront never runs it.
