# Add participants to a session

### What is this feature for?

This feature allows you to add a new registration to a session already scheduled in an existing order. This is useful for completing a customer's order without creating a new one, allowing you to group services in one place.

### Steps to add participants to a session in an existing order

1. From the dashboard, access any available session.
2. Click on **Register a participant** as for a classic order creation.
3. Fill in the participant's information.
4. Click on the **Create Order** button.
5. At the top of the screen, select the **referring customer**.
6. Below, click on the list **"add to an existing order"** the **last 5 orders less than 60 days old** will be displayed.
7. Select the order in which you want to add this inscription.
8. Complete the sale, the registration is added to the chosen order.

### Usage tips and best practices

* Check that the referring customer is selected before searching for the order to associate.
* Only **orders less than 60 days old** are displayed in the list. For older orders, you must create a new order.
* Use this method to group all services for the same customer into a single order, making management and invoicing easier.
