Rules are trust
Billing rules are not fine print; they are the daily promise of fairness. When the rule is clear, the charge feels fair even if not cheap. A vague rule generates the same question endlessly and erodes confidence. One clear, posted rule answers a thousand future calls.
Where to post
Place the rule at the point of use and in the app, not only in a contract. Seen before the bill, it prevents the surprise that breeds dispute. Costs shift with season and policy, so rules need periodic review. An outdated rule is a small error compounding across every user.
