It is very similar to the reimbursement function, however there is space to add in a PDF of the invoice onto the expense. Once they have done this it will come up as an expense that you can then approve on your collective's page. ### Submit on their behalf If you prefer, you can create the invoice **on their behalf** and add their contact details so they receive an email to review it. They will then have a chance to make any amendments or add attachments before sending it back to you for final approval. --- # Agent Instructions This documentation is published with GitBook.
