# Expenses and Income

Vault Owners and Admins can track capitalised expenses and deferred income.

## Capitalised Expenses

Capitalised expenses let you record and amortize significant operating costs over a defined period, ensuring accurate accounting within the Vault’s valuation.

{% hint style="success" %}
*Example*<br>

* *The Vault has operating expenses of **10k USD** for audit costs per year.*
* *This expense can be added as a **capitalised expense item** with a write-down period (e.g., Jan 1 until Dec 31, 2025).*
* *Whenever (partial) payments of an expense item are made, the **paid amount** needs to be tracked.*
* *The Vault’s valuation module will automatically calculate the correct accounting value of all expense items whenever a valuation update is made, taking into account both the **pro rata write-down** of the capitalised expense and the **payments already made**.*
  {% endhint %}

## Deferred Income

Deferred income lets you spread guaranteed revenue over a defined period, ensuring it is recognized gradually in the Vault’s valuation.

{% hint style="success" %}
*Example*

* *The vault has guaranteed income of **USD 10k** for the year.*
* *This income can be added as a **deferred income item** with a write-up period (e.g., Jan 1 to Dec 31, 2025).*
* *Whenever (partial) payments of the income item are received, the **amount received** must be tracked.*
* *The vault’s valuation module will automatically calculate the correct accounting value of all income items whenever a valuation update is made, taking into account both the **pro rata write-up** of the deferred income and the payments already received.*
  {% endhint %}

## 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.enzyme.finance/onyx-user-documentation/enzyme-vault/accounting/expenses-and-income.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.
