Expense reports have a way of being everyone's job and no one's. The team submits in Expensify, a manager approves, and then the reports sit: waiting to be exported, recoded into the right GL accounts, checked against receipts and finally paid out. Employees ping finance about their money, finance pings the ledger, and at month-end someone discovers a stack of approved reports that never made it into the books.
Nance takes over after the approval. Each report is booked into the administration on the correct ledger accounts and cost centers, receipts attached, with duplicates and odd claims pulled out as findings first. Reimbursements are tracked through to the actual payment and matched on the bank. Expensify keeps doing what your team likes about it; the part nobody liked is simply handled.
