Add-ons on one item

Add-ons are paid extras a customer can add to a booking, such as a helmet, extra fuel or insurance. An add-on can be linked to an item in one of three ways: Required, Optional or Hidden.

Where to find it

Fleet → open an item → Edit → Add-ons & Maintenance (step 5 of 6), then the Add-ons card.

Add-ons section on the Add-ons & Maintenance tab

How to attach an add-on from the item editor

The card lists every add-on in your account, each with Required, Optional and Hidden buttons. The buttons show how each add-on will be offered on this item:

• If you have clicked a button on a row, that mode is what you chose.
• If you have not clicked a button, the row shows how the storefront offers it based on the add-on's settings — either Optional (if the add-on has no category or belongs to this item's category) or Not offered, with no button selected.

If your account has no add-ons the card says No add-ons available.

To attach or change an add-on's mode on this item, click Required, Optional or Hidden, then click Save changes. Only the add-ons you click are saved; the rest follow the item's current category setting. To take an add-on off the storefront for this item, click Hidden.

+ Create & attach new add-on opens fields for Add-on name, Description (optional), a Price ($) and a choice of Per booking or Per day. Click Add to create the add-on in your catalog and add it to the list as Optional; then click Save changes to attach it to this item. A newly created add-on has no category, so it will be offered as Optional on every item until you set it to Hidden on items where it doesn't fit (the form explains this). If the item saves but the add-on settings fail, the editor says "Your changes saved, but the add-on settings did not. Try saving again."

The Review & Publish step lists which add-ons will be offered to customers.

Attaching add-ons through an AI assistant

You can also delegate add-on management to a connected AI assistant (Claude, ChatGPT or another MCP tool). Connect one under Settings → Integrations → AI Assistant (MCP) and tick Write for the Add-ons permission. The assistant can create add-ons, attach them to items as Required, Optional or Hidden, list which add-ons an item has, and remove them. See Connecting an AI assistant.

A developer with a write API key can also create, edit and delete add-ons in the catalog, but that route cannot attach them to an item. See API keys.

What each mode does for the customer

• Required: the add-on is pre-selected in the customer's cart.
• Optional: the add-on is offered and the customer chooses it. This is the mode when nothing is set.
• Hidden: the add-on is left out of the storefront for that item.

Example

Your catalog has a "Life Jacket Rental" add-on. Attach it as Required to a jet ski and as Hidden to a paddleboard that already includes one.

Good to know

• Add-on prices feed into the total the customer pays. See How a price is calculated.
• The admin has no screen for renaming, repricing or deleting an add-on once it is in your catalog. Use a connected AI assistant or the API for that.
