How to Spot Ghost Billing on Decommissioned Commercial Sites

Key Findings: Ghost billing on decommissioned sites is a massive drain on enterprise budgets. In one recent audit of a national engineering firm, we identified ghost billing across 40 project sites, ultimately recovering $1.4 million in carrier credits. Standard accounts payable checks rarely catch these dormant charges.

Ghost billing occurs when telecommunications services continue to generate monthly charges long after a physical site has been decommissioned. For multi-site commercial operations, this form of financial leakage is incredibly common and notoriously difficult to spot on complex carrier invoices. When a branch, retail store, or warehouse closes, the internal focus is rarely on confirming the termination of every single copper line, fibre connection, or dormant alarm circuit.

Our Multi-Site Telecom Audit process specifically targets these orphaned services by cross-referencing your active property list against carrier billing databases. We find that standard Telstra and Optus invoices rarely provide enough plain-English detail for internal teams to easily identify which location a specific service ID is attached to. This lack of visibility means that phantom charges can quietly drain your budget for years before they are discovered.

The key to spotting ghost billing is forensic reconciliation of the raw carrier data, such as the output from Telstra's T Analyst platform. It requires mapping every billed service back to a confirmed operational requirement and challenging anything that cannot be justified. For guidance on how to manage complex Telstra data, our Telstra Bills Enquiries service provides the necessary translation and analysis.

Once ghost billing is identified, the next step is proving to the carrier that the services should have been cancelled when the site was vacated. We handle the dispute preparation and negotiation, ensuring that our clients recover the funds they have overpaid for dormant infrastructure. You can read how we successfully recovered credits for similar billing issues in our case study where an engineering firm received $1.4 million in credits.

If you suspect that your organisation is still paying for telecom services at decommissioned locations, do not wait for the carrier to notify you. Independent auditing is the only reliable way to find and eliminate ghost billing across a multi-site enterprise. Reach out to Jensen IPA to schedule a preliminary review of your telecom accounts.
