🎒 Rentals: Add-ons — Optional Extras on Bookings

🧭 Overview
Rentals now supports Add-ons — optional extras that customers or admins can attach to a booking, such as a pet fee, GPS unit, guided tour, or equipment insurance. Admins can build a global catalog of reusable add-ons, attach them to listings, and configure flexible pricing with quantity controls, images, and tax support. Customers see add-ons in a dedicated section of the booking widget, can select quantities, and watch their total update in real time — with every selected add-on appearing transparently as a line item on their invoice.
🚀 What's New?
✅ Global Add-on Catalog
Admins can now create reusable Add-on items from Calendars → Calendar Settings → Rentals → Add-ons
. Each add-on includes a name, description, image, pricing configuration, max quantity, and tax settings — and can be attached to as many listings as needed without being recreated each time.
✅ Flexible Pricing Options
Add-ons support Flat amount
 (fixed charge) or Percentage
 (of base rental subtotal) pricing. Flat add-ons can be further configured as Per booking (one fixed charge) or Per booking unit (charged per hour, day, week, or month matching the listing's booking unit). Max quantity is a flat cap per booking — set how many of each add-on a customer can select.
✅ Listing-Level Attachment & Editing
Add-ons can be attached to listings directly from the global catalog — ideal for attaching one add-on across multiple listings at once — or from the Add-ons
 tab within each individual listing. Add-on settings can be edited at listing level, with changes applying globally across all listings sharing that add-on.
✅ Customer-Facing Booking Widget
After selecting dates, customers see a dedicated Add-ons section with image cards, names, descriptions, prices, and quantity selectors. Selecting or removing an add-on updates the total price dynamically. Add-ons marked Hide from booking page are not shown to customers but can still be added by admins.
✅ Tax Support
Taxes can be independently configured per add-on and are shown as a separate line — keeping amounts transparent and tax reporting accurate.
🧩 How to Use It
Go to Calendars → Calendar Settings → Rentals → Add-ons
.
Click + New Add-on
 and fill in the name, description, image (optional), pricing type, amount, pricing unit, and max quantity.
Optionally select listings to attach directly from the create modal, then click Create Add-on
.
To attach or update listings on an existing add-on, click the Edit
 icon from the Add-ons table and manage listings from there.
To configure tax on an add-on, save it first, then edit it and click Configure tax
.
Customers will see the Add-ons
 section in the booking widget after selecting dates. Admins can also add, remove, or update add-on quantities on existing bookings from the booking edit screen.
🎯 Why This Matters
Rental businesses can now upsell optional extras natively — eliminating workarounds like duplicate listings, manual invoicing, or external tools just to offer a pet fee or GPS unit.
Real-time price updates in the booking widget give customers full visibility before confirming, improving trust and reducing post-booking disputes.
A global catalog with listing-level attachment means operators manage add-ons in one place, not inside every listing individually.
Full tax and invoice support ensures add-on charges are handled correctly end-to-end — from widget to receipt.
This closes a top-requested feature from users and brings Rentals in line with industry-standard booking platforms.
