# Add an extra amount to be charged on the booking

**Adding the different fields to the survey**, with questions and answers that your users can fill in from the online calendar before booking, providing information or explanations during the survey and setting up the flow between the different survey options, is done in a **very simple and visual way in TuCalendi**.

In addition, **from the survey**, depending on the user's answers to the questions you ask to get the information you need for the meeting they are going to book with you, you **can add an extra amount to be charged on the booking**.

> [!TIP]
> We have developed a **visual editor** that lets you build the survey and set up the flow between the different steps.

[Log in](https://account.tucalendi.com/login) to your TuCalendi account. Go to the **"Survey Templates"** option:

![Survey templates](https://www.tucalendi.com/images/content/surveys/en/v2-survey-templates.png)

To create a new survey, click on **"New"**.

There are two types of surveys available:

- **Standard**. This is a new survey that can be assigned to each event type.
- [Standalone](https://www.tucalendi.com/en/s/surveys/creating-an-intelligent-survey-with-routing). This is a new survey that can be used as a **standalone widget** and with **routing** to different event types.

In the **"Add amount"** field, you can enter an **extra amount** to be charged at the time of booking. When you're done, click on **"Add"**:

> [!WARNING]

You can either **add** an amount to be charged on a booking or **subtract** an amount from the booking. Just select **"+"** to add an amount or **"-"** to subtract an amount.

When you have added the options and completed the **flow** by joining the boxes, click **"Save"**.

> [!WARNING]
> To **join the boxes**, click on the point to the right of the initial box, keep the mouse button pressed and draw the line to the point to the left of the box you want to connect.

To make the survey visible, you must [**choose the event you want to associate the template with**](https://www.tucalendi.com/en/s/availability-configuration-events/assigning-survey-event). This way your users and customers can respond to the survey you have created. In this case, **30 Euros will be added to the normal amount charged for the meeting**.

> [!TIP]
> From the survey and based on your clients' responses, you also have the option to **subtract the amount** from the booking.
