# Add-ons and add-on groups > Build add-on groups of options and add-on services, set how many clients pick, choose which services offer them, and turn groups off. Source: https://heylilo.co/help/services/add-ons Add-ons are extras clients can pick when they book a service, like extra time or a finishing touch. You build them in add-on groups. A group holds the extras and the rules for choosing them, and you pick the services it's offered with. A group can hold two kinds of items: - **Options** change the service they're picked with. Each one can add to or take off its price and length, or change neither, like a preference. - **Service items** add one of your services to the appointment, done by the person doing the main service. ## Create an add-on group **Applies to:** Owners, admins and location managers 1. Go to [**Catalog** → **Add-ons**](https://app.heylilo.co/dashboard/catalog/add-on-groups) and select **New group**. 2. Enter a **Name**. 3. Enter a **Client prompt**, like "Want to add a finishing touch?" Clients see it above the group's items when they book. 4. Set the rules under **How clients choose**. **Group rules** below explains each one. 5. Select **Create group**. You'll see **Add-on group created**, and the group opens. Next, add items and choose the services that offer the group. You can also start from a service. Open the service's full page and select **Add-ons**, then **Add an add-on**. Add at least one item and select **Create add-on**. Lilo makes a group that's offered with that service, and you can attach it to others later. ## Add an option **Applies to:** Everyone except service providers 1. On **Catalog** → **Add-ons**, select **Edit** next to the group. 2. Select **Add option item**. 3. Enter a **Label**. Clients see it. 4. Under **Price adjustment**, choose **Add (+)** or **Subtract (−)** and enter the amount. 5. Under **Time adjustment (minutes)**, choose **Add (+)** or **Subtract (−)** and enter the minutes. 6. Select **Add**. You'll see **Option added**. Leave both amounts empty for a free choice, like a preference. ## Add a service item **Applies to:** Everyone except service providers 1. Open the group and select **Add service item**. 2. Select the service. 3. To use a different price or length, enter a **Price override** or **Duration override (min)**. Leave them empty to use the service's own. 4. To show clients a different name, enter a **Client label (optional)**. 5. Select **Add**. You'll see **Service item added**. ## Choose which services offer the group **Applies to:** Everyone except service providers 1. Open the group. 2. Under **Offered under**, check every service the group should show with. Uncheck a service to take the group off it. Each change saves right away. You can also attach a group from a service's full page. Select **Add-ons**, then **Attach existing group**. See [Service details](https://heylilo.co/help/services/service-details) for how to open that page. ## Change a group **Applies to:** Everyone except service providers - **Rules:** next to **Group settings**, select **Edit**. Make your changes and select **Save rules**. You'll see **Group updated**. - **An item:** select the pencil next to it, make your changes and select **Save changes**. - **Item order:** drag an item by its handle. Clients see items in this order. - **Remove an item:** select the trash can next to it, then **Remove**. Past bookings don't change. - **Preselect:** turn it on for an item to have it start checked when clients book online. ## Stop offering a group **Applies to:** Everyone except service providers On **Catalog** → **Add-ons**, turn off the group's switch. Clients and your team stop seeing the group, and it keeps its items and services. Turned-off groups leave the list. To turn one back on, turn on **Show inactive**, then turn on the group's switch. **Applies to:** Owners, admins and location managers **Archive group**, at the bottom of a group's page, does the same thing. You'll see **Group archived**. ## Show add-ons on your booking page **Applies to:** Owners and admins Add-ons show on your booking page only while **Show Add-ons** is on. It's on unless you turn it off. To check, go to [**Settings** → **Booking Page**](https://app.heylilo.co/dashboard/settings?tab=booking-page). The switch is under **Features**. If you change it, select **Save Changes**. See [Booking page settings](https://heylilo.co/help/booking/booking-page-settings). ## How it works ### Group rules - **Allow multiple**: clients can pick more than one item. With it off, they can pick one at most. - **Required**: clients have to pick from the group. A required group needs a **Minimum selections** of at least 1. - **Minimum selections**: how many items clients have to pick. 0 means none. - **Maximum selections**: the most they can pick. Leave it empty for no limit. - **Display order**: groups with lower numbers show first. - **Active**: turn it off to stop offering the group. ### What clients see online - After clients choose their services, Lilo shows each service's add-ons before they pick a time. - Each group shows its **Client prompt**. With no prompt, clients see the group's name. - Each group is marked **Required** or **Optional**. A group with a limit says how many to pick, like **Choose one**. - Each item shows what it adds to the price and time. Items that change neither show **Included**. - Items with **Preselect** on start checked. Clients can uncheck them. - Clients can't go on until they've picked enough from each group. ### When your team books - In **New Appointment**, add-ons show under each service you select. Select an item to add it, and select it again to take it off. - Required groups are marked with *. Once you add any add-on, Lilo checks every group's rules for the appointment. - **Preselect** only applies online. Nothing starts checked when your team books. - [Recurring appointments](https://heylilo.co/help/calendar/recurring-appointments) don't get add-ons. Lilo books a repeating appointment without them. In the Lilo app, add-ons show under each service you pick when you book. To change your groups, go to **More** → **Add-ons**. ### Prices and who does it - An option changes the price and length of the service it's picked with. It isn't a separate service on the appointment. - Lilo books a service item as its own service, right after the main one, with the same person. - If the service in a service item requires a deposit, clients pay that deposit too when they book online. Options never add a deposit. ### When a service item doesn't show A service item only shows when all of these are true: - Its service is bookable online, including when your team books. - Its service is offered at that location, or it's offered only as an add-on. - Someone at that location performs both it and the main service. If a provider was picked first, that person has to perform both. Options always show. A service item also has to happen in the same place as the main service. One done at the client's address only shows with main services done at that address. See [Services at the client's address](https://heylilo.co/help/services/services-at-client-address). ## Common questions ### Why don't clients see my add-ons? Usually it's one of these: - **Show Add-ons** is off in **Settings** → **Booking Page**. - The group is inactive. - The group isn't offered with the service the client picked. - A service item's service isn't bookable online, or nobody at that location performs both services. ### Why does Lilo say a group needs a selection? The group's **Minimum selections** is more than 0. Clients booking online have to pick from it. When your team books, Lilo checks it once you add any add-on to the appointment. ### Can clients see the group's name? Only when the group has no **Client prompt**. Then clients see the name above the items. ### Can I add add-ons to a package? No. Add-ons are only offered with services picked on their own, not with the services in a [package](https://heylilo.co/help/services/packages). ### Can I delete an add-on group? No. Turn it off instead. It keeps its items and services, so you can turn it back on later. ### Who can change add-ons? The owner, admins and location managers can do everything. Front desk can change groups and items, but can't create groups or archive them.
