Expense -> Project -> Invoice + Expense recipets.

Given that expenses can be submitted and assigned to customers/projects it would be useful to have an easy way to pull all attachments associated with expenses/expense Recipets onto the invoice as an attachment.

This could be a report that is generated as part of the invoicing process or pulling over the individual recipet images /recipet attachments.

This means that they are transparent to the client.

Saves the highly manual process of reporting each projects assigned expenses, opening each Expense down loading the recipets/attachments. Then adding each if these to the invoice. Lots and lots of manual steps.
