You can attach files to an Invoice that will be included when the Invoice is emailed to a client (from within the Invoices tool).
This is a great feature if you want to include any attachments with an Invoice (like receipts for bill-through items, inventory lists of items delivered/provided, etc.). You can attach a variety of files, including documents, PDFs, spreadsheets and images.
To Attach Files to an Invoice:
Once the files are uploaded, you can download them or delete them from the Invoice Dashboard. When you email an Invoice from the Invoice Dashboard or add a Payment Reminder to be emailed at a later date, the attached files will be attached to the email along with a PDF of the Invoice.
