The problem to investigate
A reference to the contract as a whole is too broad to verify a disputed line. The comparison needs the specific schedule, scope, period, and calculation assumptions.
Common causes to check
- Invoice service codes not mapped to contract items
- Proration rules omitted from calculations
- Conditional discounts treated as unconditional rates
What your organization should review
- Map each reviewed charge to its contract item
- Write out quantity, rate, and period assumptions
- Document exclusions and any required eligibility test
Verification and supporting evidence
Keep a comparison worksheet with source references and the applicable clause. Another reviewer should be able to reproduce the conclusion without reconstructing the entire agreement.
Illustrative review example
A monthly charge spans a rate-change date. The worksheet separates the periods and applies the documented proration rule rather than comparing the total with either full-month rate.
How this fits the AuditRes workflow
Use Telecom contract reconciliation to support the comparison, then preserve the calculation as evidence for human verification and any subsequent recovery case.
AuditRes Telecom supports secure carrier billing intake, invoice normalization, reconciliation against contracts and service inventory, human verification, evidence-backed findings, and recovery case management. A flagged difference remains a review candidate until the supporting records establish what happened.
Frequently asked questions
What should an expected-charge calculation show?
It should show the applicable service, units, rate, dates, and adjustments, plus where each input came from. Unresolved inputs should remain explicit.
Does a finding guarantee a credit or refund?
No. A finding records a reviewed discrepancy and its evidence. The carrier response and the documented financial outcome determine whether a case produces a credit, refund, partial adjustment, or no recovery.
