The Multi-Site Guide to Auditing Telstra and Optus Invoices
For Australian businesses operating across multiple locations, telecommunications billing is inherently fragmented. Over time, as branches open, relocate, or are acquired, the complexity of Telstra and Optus accounts increases exponentially. This complexity hides significant financial leakage. We identify and recover capital lost to decommissioned sites, orphan SIMs, expired tariffs, and chaotic inherited accounts.
Stop Paying for Decommissioned Sites and Phantom Services
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. This results in ghost billing, where disconnected services continue to generate monthly charges long after a physical site has been decommissioned. Our multi-site audit process cross-references your active property list against carrier billing databases to isolate these phantom charges. We then manage the dispute hand-off, as detailed in our Dispute Management service, to recover your overpaid funds.
Untangling Inherited Telco Accounts After M&A
Following a merger or acquisition, integrating the acquired company's telecommunications infrastructure is often a lower priority than consolidating core IT systems. Inheriting unoptimised legacy accounts frequently results in duplicated services and missed volume discounts across both Telstra and Optus networks. Our multi-site audit maps the acquired services, verifying they are actually needed, and ensures they are moved under your master enterprise agreement to capture volume discounts.
Recover Expired Discount Tariffs and Orphan SIMs
When enterprise contracts expire, negotiated discounts often automatically roll off, and services revert to expensive standard retail rates. Simultaneously, mobile services can continue billing months or years after employees have left the organisation, creating orphan SIMs and data pools. We forensically review the underlying tariff codes applied to every service, comparing the billed rates against the active or recently expired enterprise agreement. For an example of the impact of independent auditing, review how a National Engineering Firm recovered $1.4 Million through forensic analysis.
Dedicated Enterprise Billing Support
Successfully untangling multi-site accounts requires deep knowledge of how carriers structure their backend databases and billing hierarchies. For complex Telstra environments, our Telstra Bills Enquiries service specialises in decoding T Analyst data. We manage the entire consolidation audit, providing the evidence needed to clean up the accounts and dispute any historical overcharges associated with the acquisition.
