Gas billing refers to the process of calculating and charging customers for the natural gas they consume. Utility companies measure gas usage through meters installed at customers' premises, recording the amount of gas used over a billing period. This data is then used to generate monthly or bi-monthly bills, which include the total consumption, applicable rates, and any additional fees or taxes. Customers typically receive their gas bills via mail or electronically, detailing the usage and charges. Payment options may include online payments, bank transfers, or traditional methods like checks. Understanding gas billing helps customers manage their energy costs effectively.
