Setting Up Extras
Extras are add-ons customers can tack onto a booking. Every extra is one of three kinds:
- Just a charge β a fee or service with nothing physical behind it (insurance, a photo package, a cleaning fee).
- Rental item β kit they borrow and bring back (a helmet, a dry bag, a camera). It's backed by one of your rental products, so it uses that product's own pricing and stock.
- Store product β something they buy and keep (a spare battery, a water bottle). It's backed by one of your store products.
Set an extra up once, choose where it's offered, and it appears everywhere that item is booked β your booking widget, the POS, and bookings created by Dash AI or the API.

Creating an extraβ
-
Go to Rentals β Extras (the same page is also under Experiences β Extras).
-
Click Add Extra.
-
Under What kind of extra is this?, choose one β this decides how it's priced and stocked:
Just a chargeβ
A fee or service β nothing physical, so it's always unlimited.
- Enter the Price.
- Choose how it's Charged: Once (one charge each time it's added), Per person (multiplied by participants on experiences), or Per time period (multiplied by the rental length β pick day, hour, or week, e.g. a bike light at $2 / day).
Rental itemβ
They borrow it and bring it back.
- Under Which rental item?, pick one of your existing rental products.
- Its price and stock come straight from that product β including any schedule or seasonal pricing you've set. There's no separate price to enter.
Store productβ
They buy it and keep it.
- Under Which store product?, pick one of your existing store products.
- Its price and stock come straight from that product.
-
Enter a Name customers will recognize, and optionally a short Description (shown under the name wherever it's offered).
-
Choose where it's offered β each is a dropdown with the same choices:
- Available on rentals β All products, Specific categories, Specific products, or Not available on rentals.
- Available on experiences β All experiences, Specific categories, Specific experiences, or Not available on experiences.
Picking a "Specificβ¦" option reveals a picker to choose the exact categories, products, or experiences.
-
Click Add Extra.

A single extra can be offered on rentals and experiences at once β a helmet can appear on your bike rentals and your guided bike tours. Set both "Available on" sections and you're done.
Rental & store extras: you link an item you already haveβ
For a Rental item or Store product, you link an existing item rather than recreating it. Two things follow automatically:
- Pricing is always right. The extra charges exactly what the linked product charges β including schedule and seasonal rates on rentals. Change that product's price once and every extra linking it updates too. No stale prices.
- Stock is real. Booking a rental extra reserves a unit of the linked product for those dates and frees it on return; a store extra depletes the linked store product's stock. Customers can't over-book what you actually have.
Only available as this add-onβ
When you link an item you'll see an Only available as this add-on toggle:
- Off (the default) β the item stays in your normal rentals list / store and is offered as this add-on.
- On β the item is hidden from your rentals list, store, POS, mobile app, and online. It can only be booked as this extra, and it shows an Add-on only tag in your product/store list so you can spot it at a glance.
Turn it on for kit you never rent or sell on its own β a trail camera you only offer alongside a rental, say.
Where customers see extrasβ
- Booking widget β available extras appear right under the quantity selector with their prices. A rental extra shows its linked product's rate; adding one updates the running total. On experiences, extras appear after the customer picks a time and participants.

- POS β staff get the same one-tap steppers when they expand a product or experience card.
- Cart, checkout, and booking details β each added extra is listed under its item with its price, and the line total includes it.
Editing and deletingβ
- Edit an extra (pencil icon) to change its kind, its linked item, or where it's offered. For rental and store extras, price and stock always follow the linked item β edit that product to change them. Changes apply to new bookings only β existing bookings keep the price the customer was charged.
- On the edit form, toggle Active off to hide an extra everywhere without deleting it β handy for seasonal extras.
- Delete an extra (trash icon) to remove it from the catalog. Bookings that already include it keep their charges, and the linked product or store item is not deleted.
