# Set the business time zone and download statements

Choose the time zone that decides where budget days and months begin, and find your monthly invoices and allocation statements.

## Before you begin

- To change the time zone, you need the Owner or Admin role.
- To download statements, you need the Owner, Admin or Account Manager role.

## Set the business time zone

1. In the sidebar, open **Manage** > **Details** and stay on the **General** tab.
2. Unlock editing with the lock control next to **Business time zone**.
3. Choose a time zone from the list. The default is `Europe/Amsterdam`.
4. Save. A **Business time zone updated** message confirms the change.

**Result:** budget days and months, statistics periods and monthly project limits now start at midnight in this time zone. ATLAS doesn't recalculate statements for months that are already closed.

## Download statements

1. In the sidebar, open **Statistics** > **Billing**.
2. Select a month. The current month is a live preview. Closed months are frozen.
3. Download what you need:
   - The monthly invoice PDF, from the **Documents** column on the **Invoices** tab.
   - The **AI subscriptions estimate**, from the same column. It appears only if you use your own provider accounts, and it's informational, not an invoice.
   - The internal allocation per Unit, on the **Internal allocation** tab, once the month is closed.
   - The contract revision PDFs, on the **Contract** tab. They appear once your organisation has a contract revision.
   - Statements of deleted projects, in the **Cost reports of deleted projects** card on the **Invoices** tab.

Managers of a Unit find the allocation statements for their Unit on the **Cost reports** tab of the Unit space.

## Troubleshooting

Look up any code at `https://<atlas-host>/errors/<code>`, where `<atlas-host>` is your ATLAS host. [Errors](https://docs.atlas.ilionx.dev/reference/errors.md) explains how ATLAS reports them.

| Symptom             | Cause and remedy                                                                                | Code       |
| ------------------- | ----------------------------------------------------------------------------------------------- | ---------- |
| "Invoice not found" | The statement does not exist yet, or its month is not closed. Try again after the month closes. | `ERR-0133` |
