What is it?

Supporting Documentation is any original receipt or other related document that shows the cost of an expense, provides proof that an item has been paid, and/or indicates that an activity has taken place, (e.g. boarding pass for a flight to confirm use of an airline booking) to support a financial transaction.

Why is it important?

Carleton University, as a publicly funded institution, is required to keep all supporting documentation for audit purposes. Originals are required to show proof that reimbursement has not been sought elsewhere and to prove authenticity and validity of the reimbursement.

Where do I find more information?

  • Review the “What supporting documentation do I need for each expense” section on the Expense Items webpage.
  • If you are missing any supporting documentation review the “I lost a receipt or boarding pass. What should I do?” section on the Expense Items webpage.
