Answer:
For Order Requests
Procurify will store the currency rate of items for the purchasing date. Updating the currency rates will not change the amounts of items already purchased.
Pending and Approved order requests will continuously update to reflect any changes in currency rates, even when viewing order requests after items have been purchased. We suggest not using order request data to report on items already purchased.
For Expense Requests/Reports
Procurify will store the currency rate for expense requests upon approval.
Additional Information:
Procurify Budgets does not support switching the base currency.
