The problem
The receipt is months old, but the expense form keeps converting it at today's rate.
Using a live rate changes the historical amount and leaves no evidence for a weekend, holiday, pair direction, or chosen date convention.
Employees, travelers, bookkeepers, and expense reviewers
Today's rate cannot explain an old receipt. Use the receipt date, actual data date, pair, source URL and reference conversion to create a reviewable record.
Invoice exchange rate
Weekends and holidays may return the nearest available working-day rate. The result shows the actual data date.
For an old receipt, keep the original amount and receipt date, use a dated reference conversion, record any actual available data date, and save the exact FXpeek source URL with the reimbursement record.
