The Add-ons tab lets you manage additional features or upsells, usually these are supplementary services or products related to the main service. These offerings can increase revenue and enhance customer satisfaction by giving clients more personalized service options during the booking process.

The information will be organized as:

1. Name: This is the name of the service that customers see.
2. Duration: This indicates how long the add-on will take to complete, if applicable.
3. Price: This section contains the cost of the service for customers.
4. Services: Here you can see all services where this add-on can be included.
5. Edit: This lets you access the Add-on creation module to modify any details needed. 
6. Delete: Use this option to permanently remove the add-on.

Creating An Add-on

To create a new add-on, click the "New Add-on" button.

Fill in the details:

1. Add-on Image: Upload an image to represent the add-on visually.
2. Name: This is the name of the service that customers see.
3. Price: Set the cost of the add-on.
4. Duration: Check the box if your add-on has its own duration. When enabled, this duration will be included in the total service time for customers.
5. Maximum Quantity: Define how many units can be selected per appointment.
6. Multiple Price with Quantity: If enabled, price is multiplied by the number of units (e.g., $20 × 2 qty = $40).
7. Description: Add details to explain what the add-on is and why it should be purchased.
8. Hide from Booking Page: Keep the add-on internal, so only staff can apply it.
9. Once you've filled out the information, click Create Add-on to save it.

After creating an add-on, you must go to each service where you want it available and assign it there. Add-ons will only appear on the booking page for the services they are linked to, so customers will then see them as an optional extra during booking.
