Trade-in credit checker
Trace a phone trade-in credit from the offer to the bill.
Direct answer: Phone Deal Audit separates any immediate trade-in value from recurring bill credits, then compares the remaining promotional value with the bill timeline you confirm.
Why the calculation can be confusing
The headline promotion, market value of the old device, monthly credit, and device installment are different amounts. The relevant formula depends on the specific offer and how the carrier applies immediate value.
A precise comparison
Money is calculated with decimal arithmetic rather than floating point. Each bill receives an expected amount, actual amount, variance, line reference, and plain-English assessment.
Your confirmation matters
Scanned bills and changing carrier labels create ambiguity. You review extracted candidates and correct the record before the deterministic analysis runs.
