Accountants' Workshop: Spotting Telstra Billing Red Flags on Client Statements

When Jensen IPA recently presented to the Brisbane Northside Accountants Discussion Group, the room quickly filled with familiar stories. Practicing accountants, commercial bookkeepers, and virtual CFOs across South East Queensland shared ongoing frustrations with trying to interpret and resolve telecommunications accounts on behalf of their commercial clients.

Whether advising medical clinics, construction firms, manufacturing operations, or professional services practices, accountants routinely encounter fluctuating, incomprehensible carrier bills that drain cash flow.

To assist advisory practices across Australia, here is a summary of the key telco billing red flags we discussed and how accountants can spot them during regular financial reviews.

The Problem: Communications Expenses Outpacing Business Growth

In an ideal financial model, telecommunications overheads should correlate predictably with headcount and physical locations. When a client adds five staff, mobile and SaaS expenses might rise incrementally.

However, when an accountant reviews the Profit & Loss statement and observes that communications expenses have jumped 25% to 50% year-on-year without a corresponding increase in operational volume, it almost always points to compounding carrier billing errors rather than legitimate usage.

4 Telco Red Flags Accountants Should Look for on Financial Statements

1. Inconsistent Monthly Variances on Fixed Invoices

Fixed services—such as NBN business connections, SIP voice trunks, and cloud PABX licenses—should remain virtually identical month after month. If your client's fixed communications ledger swings by hundreds or thousands of dollars each billing cycle, carrier billing mainframes are likely misrating data usage or applying unauthorized connection surcharges.

2. Expired 24- or 36-Month Contract Schedules

Examine the client's original vendor agreements. If a 24-month or 36-month enterprise schedule expired 6 months ago, the carrier has almost certainly stripped away volume discounts (typically 20% to 40%) and reverted all lines to maximum commercial rack rates.

3. Lingering Supply & Equipment (S&E) Capitalised Rentals

Look for recurring monthly charges classified as S&E or equipment lease payments. In numerous client audits, we discover businesses paying $500 to $2,000 per month for telephone hardware, modems, or PABX cards that were physically scrapped half a decade ago.

4. Discrepancies Following Office Relocations or NBN Migrations

If a client relocated premises or migrated from copper to NBN in the last 12 to 24 months, their telecom invoices almost certainly carry duplicate line rentals for vacated addresses or disconnected PSTN/ISDN services.
