What are adjustments?
-
Partial credits to the customer
-
Full credit on one MSISDN
-
Negative one off charge
-
Recurring partial credits
Adjustments in billing systems are negative one-off charges applied to customer accounts to correct errors, provide refunds, or make manual corrections. Unlike partial credits (Option A) or full credits on a single MSISDN (Option B), adjustments are specifically designed as debit reversals. Option D describes recurring credits, which are a different mechanism from one-off adjustments.
In billing/telecom systems, an adjustment typically refers to a one-time negative charge applied to correct or credit an account, distinct from a recurring charge or a full account credit. This is why it's characterized as a 'negative one off charge' rather than a partial or recurring credit.
