Meal limits look simple on paper: a daily cap, a guest count rule, and a receipt requirement. In practice, claims drift when a dinner is split across two submitters, when a tip is added after the card slip is photographed, or when a foreign currency amount is converted with an outdated rate.
During sampling work in Taipei, we often see the same pattern. An employee books a client dinner under the entertainment category, attaches a blurry photo, and the approver focuses on the guest list rather than the arithmetic. By the time finance reviews the batch, the overage is buried inside an otherwise tidy claim pack.
A practical control is to require the original itemized bill plus a one-line conversion note when the spend is not in New Taiwan dollars. Approvers then check three numbers only: guest count, converted total, and the category limit. Anything else can wait for a later exception conversation.
If your policy still says “reasonable meal expenses” without a number, expect inconsistent approvals. Controllers who publish a clear weekday and weekend cap usually see fewer disputes within one quarter of the change.
