Most documents have an **Attachments** area: drop files, select **Upload**, or paste an image from the clipboard. Use it for supplier PDFs, signed delivery notes, receipts and contracts.

## What you can attach

- PDFs and images (JPEG, PNG, WebP), up to 10 MB each.
- Attachments are allowed on invoices, purchases, expenses, payments and supplier payments, sales and purchase returns, journal entries, and on the business itself (the logo).

## Where they live

Files stay with the document; open the document to see, download or remove them. The **attachments** count appears on list rows. Receipt photos sent to the AI assistant become attachments of the resulting document once you confirm it.
