Check for duplicates in Payables when the invoice/reimbursement is first entered. This would alert the person submitting the request. Currently we have to wait until our final approver, the VP of Finance, reviews before the system will give an Duplicate Invoice warning. It would be better practice if this were caught earlier in the cycle and not wait until the final approval. (Expense Management would need to connect to Payables from the beginning of the process instead of all the way at the end)
