# Adding attachments to an invoice or quotation

In CoMange you can send attachments separately or merge them with the original invoice or quotation. 

||| If you want to merge files as one PDF file, you can only work with PDF documents.

### To add a separate attachment

1. Open your invoice or quotation, scroll to the attachments section and click it open.
