# Attachments

Pleo supports exporting attachments associated with expenses, such as receipts and supporting documents.

Attachments are provided as part of Export Items and can be retrieved by integrations for storage in an Accounting System.

## Attachment Availability

Attachments are included when:

* an expense has one or more uploaded files
* the files are accessible at export time
* the Export Item passes validation

Each attachment is exposed through the Export Item payload.

## Attachment Data Model

Attachments are available via:

* `files.url` — secure download URL
* `files.type` — file MIME type
* `files.size` — file size in bytes

The integration is responsible for downloading and storing attachments in the destination system.

## Supported File Formats

Pleo supports the following attachment formats:

* `.doc`, `.docx`
* `.pdf`
* `.txt`
* `.jpg`, `.jpeg`, `.png`
* `.xls`, `.xlsx`

## File Size Limits

* Maximum supported file size: **30 MB per attachment**

Files exceeding this limit may not be available for export.

## Multiple Attachments

A single expense may contain multiple attachments.

The Export Item returns all associated files individually.

## Platform Behaviour

* Attachments remain linked to their originating expense.
* Download URLs are time-limited and should be retrieved promptly.
* File ordering is preserved as uploaded in Pleo.
