Plain-language definition
An adjustment is a correction or change applied to a bill or account balance after charges were originally calculated.
Why it appears on a bill
It may appear after an error correction, service change, meter update, refund, credit review, or recalculation of a previous period.
What to check
- Confirm whether the adjustment is a charge or credit.
- Ask what period or line item it relates to.
- Compare it with any promised correction.
- Make sure the same issue is not adjusted twice.
