# Company Data

Your company profile is the basis for all your documents. From here, you configure the data that appears on invoices, quotes, and other tax documents.

## Basic Information

### Legal and Commercial Name

The **legal name** is the name registered with the commercial registry or the tax administration. It is the one that must appear on all your tax documents.

The **commercial name** (optional) is how clients and vendors know you. If you use both, the legal name appears on invoices, and the commercial name can be used in marketing communications.

```
Ejemplo:
Nombre legal: Acme Spain, S.L.
Nombre comercial: Acme
```

### Tax Identifier

Enter your **NIF** (Tax Identification Number), **CIF** (Tax Identification Code), or **NIE** (Foreigner Identification Number) according to your entity type.

Frihet automatically validates the format:
- **NIF**: 8 digits + 1 letter (e.g., 12345678X)
- **CIF**: 1 letter + 7 digits + 1 digit/letter (e.g., A12345674)
- **NIE**: X, Y, or Z + 7 digits + 1 letter (e.g., X1234567L)

This identifier appears on all your invoices and is mandatory for tax operations in Spain.

## Contact

### Billing Email

Your main contact email. It is used for:
- Received payment notifications
- Pending document alerts
- Frihet communications about your account

### Phone

Contact number that may appear on your commercial documents. The format is automatically standardized.

### Website (optional)

Your company URL. It appears on documents if you include it in the invoicing template.

## Address

### Configuration and Autocomplete

Frihet integrates address autocomplete to speed up entry. Type the street and the application suggests options.

The required fields are:
- **Street and number**: Full address of the tax domicile
- **Postal code**: Mandatory to validate the province
- **Municipality**: It is autocompleted based on the postal code
- **Province**: It is automatically determined

The full address is mandatory and must be your tax domicile or the address where you carry out your economic activity.

## Document Presentation

The data you configure here is automatically inserted into:

- **Invoices**: Document header and footer
- **Quotes**: Seller data
- **Receipts**: Billing information
- **Credit notes**: Company details

You can review how they look in the **preview** before saving changes.

## VeriFactu Responsible Declaration

At the bottom of the tax profile, the **software's responsible declaration** is displayed, mandatory for invoicing systems in Spain (Art. 20 RD 1007/2023).

This section shows:

| Field | Value |
|-------|-------|
| Software | Frihet ERP v1.0 |
| Manufacturer | (Configured in **Settings** > **Compliance** > **VeriFactu**) |
| Manufacturer's NIF | (Configured in **Settings** > **Compliance** > **VeriFactu**) |
| Hash chain | SHA-256 |
| Regulation | RD 1007/2023, Orden HAC/1177/2024 |

This information is read-only and is included automatically. For more details on Frihet's compliance, consult the [VeriFactu documentation](/cumplimiento/verifactu).

## Future Changes

Modifying your company data automatically affects new documents. Documents already issued retain the data they had at the time of issue, thus complying with tax requirements for [immutability](/cumplimiento/inmutabilidad).

If you change your address or tax identifier, update this data as soon as possible to maintain consistency with your official records.
