# Set your business summary, hours and languages

> Edit the business summary, opening hours, customer and team languages, time zone and currency that every AI agent in your workspace uses.

**Business** > **Details** holds what's true of the business itself, so every agent in the workspace uses the same answers. Click **Business** in the sidebar, then **Details**.

## Business summary

The business summary is what your agent tells callers when they ask what the business does or offers. It reads the summary before every call.

You don't have to write it. When you add your website or documents in [Knowledge](https://docs.lobbystack.com/settings/knowledge.md), AI writes a summary of two to four sentences from them, in your default customer language. It rewrites the summary a few minutes after your knowledge changes, and only when the content changed.

To write your own, click **Edit** beside **Business summary**, change the text, and click **Save**. AI never changes a summary you wrote.

To go back to an AI summary, click **Edit**, then **Rewrite with AI**. AI rewrites the summary from your knowledge and tells you when it's done. If your knowledge doesn't say what the business does yet, the summary stays as it was.

## Opening hours

Your agents book appointments only inside your opening hours. With instant booking on and no hours set, an agent can't offer a time. It takes the caller's request as a message for your team instead, and the agent's booking settings show a warning until you add hours.

You don't have to type them in. When your website or documents state your hours, AI fills in **Opening hours** a few minutes after your knowledge changes. It reads hours in any language and saves a lunch break as two windows on the same day. It only uses hours your sources state, and a note above the hours tells you to check them.

To set the hours yourself, turn each day on or off and enter its times. Click **Add hours** for a second window around a break, then click **Save hours**. AI never changes hours you saved here or through the API.

For holidays and other times you're closed, click **Add closure** and enter when you close and reopen. Use your business timezone, then click **Save hours**. Your agents won't book appointments during a closure. They tell callers the business is closed then and offer another day.

## Default customer language

Calls open in your **Default customer language**: your agent greets callers in it. When a caller asks for another language or speaks one, your agent switches to it. It can talk with callers in more than 70 languages.

The **Default customer language** setting supports:

| Option | Value |
| - | - |
| English | `en` |
| French | `fr` |
| Spanish | `es` |
| Serbian (Latin script) | `sr` |
| German | `de` |
| Portuguese (Brazil) | `pt` |
| Italian | `it` |
| Dutch | `nl` |
| Polish | `pl` |
| Turkish | `tr` |
| Vietnamese | `vi` |
| Tagalog | `tl` |
| Swedish | `sv` |
| Russian | `ru` |
| Ukrainian | `uk` |

Choose the language most of your callers speak. An agent whose greeting you haven't changed switches to the default greeting in the new language.

> [!NOTE]
>
> Add greeting, knowledge, service, and rule content in the languages your callers are most likely to use.

## Team language

**Team language** is the language your agents write messages, notes and requests in for your team. Callers still hear their own language. Pick **Same as customer language** to follow the default customer language.

## Business timezone

Your agents use the **Business timezone** for your opening hours and for the appointment times they offer customers.

## Currency

Pick the currency your [service prices](https://docs.lobbystack.com/settings/services.md#prices) are in from **Currency**. Your agents quote prices in it. If you change the currency later, the amounts you entered stay the same.
