PB and HB charges have different billing needs, affecting how validation checks should be configured.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Billing validation checks must match how each charge type is calculated. PB charges are often usage-based, tied to time windows and variable units, so validation should verify that the reported usage, the correct per-unit rate, and the resulting amount are consistent, along with proper currency handling. HB charges might be fixed or tiered, with a base fee plus taxes, surcharges, and possible discounts, so validation needs to ensure the base amount, tax calculation by jurisdiction, and any discounts are all applied correctly. Because the underlying data and rules differ, the validation rules should be tailored to each type rather than a single, uniform set. When the checks reflect these distinct needs, the risk of misbilling or tax/discount errors is reduced. So the statement is true.
