# Invoicing

## **Invoice method**

### **a - Trading robots**

Every time your robots complete a transaction, i.e. a sale, we will calculate your earnings.

On the 1st day of each month, we will generate the invoices

To do that, we calculate the total of all your earnings of the previous month in US dollars (USD). If you don't use a currency index-linked to dollar, the equivalent in USD is worked out when the invoice is generated.

The sum owed to Whalinvest will be equal to **20% (excluding tax)** of your total earnings. If you earned nothing you pay nothing.

### b - Recurring investment

The recurring investment service is billed monthly as follows:\
👉Classic – $5.99/month\
👉Smart – $9.58/month\
👉and Smart Dip – $9.58/month

### c - Trading Agents

Trading agent fees are tiered based on your portfolio value and charged on a monthly basis:\
👉 **1.5%** annually for portfolios from $1 to $4,999\
👉 **1%** from $5,000 to $19,999\
👉 and **0.75%** for $20,000 and above

For example, with a portfolio of **$410.42**, your current annual fee rate is 1.5%, resulting in a monthly fee of **$0.51**.

## **The bills**

You will find a list of all your bills on the *Bills* page.

An unpaid bill presents as below :

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.whalinvest.com/english/invoicing.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
