Why Telecom Is the Most Overlooked Category in Indirect Spend.

And what it's costing enterprise organisations every year.

Ask a CFO, CIO or Procurement leader to name their top indirect spend categories and you'll hear the same answers: professional services, facilities, technology, travel.

Telecom rarely makes the shortlist.

That's not because it's small. In most medium-to-large enterprise environments, telecom represents a material line item, often $500k to several million dollars annually across mobile, data, voice, and internet services.

It's overlooked because it's invisible. And invisible spend compounds.

The Approval Problem

Telecom invoices don't get reviewed. They get approved.

In most organisations, telecom bills move through accounts payable with minimal scrutiny. They look like last month. They match the expected range. They get signed off.

This isn't negligence. It's a structural problem. Telecom is rarely owned end-to-end by a single team. IT manages the services. Finance approves the invoices. Procurement may have negotiated the original contract — years ago. Nobody has the full picture.

The result is predictable: Cost drifts. Quietly. Consistently. For years.

Where the Overspend Hides

Across 20 years and 500+ enterprise telecom audits, the same patterns emerge regardless of industry, size, or carrier:

•      Legacy services still billing after technology changes.

An infrastructure upgrade happens. The old ISDN lines, data circuits or network services aren't cancelled. They keep billing, sometimes for years.

•      Mobile fleets misaligned with usage.

Plans were set up years ago based on different usage patterns. The business has changed. The plans haven't.

•      Contracts on rollover.

Renewal dates pass without review. Organisations stay on expired terms, often significantly above current market rates.

•      Billing errors that were never queried.

Overcharges, duplicate services, incorrect rate applications. They sit in invoices that get approved without line-item review.

•      Incomplete or non-existent asset registers.

No one knows exactly what services are active, where they sit, or whether they're still needed.

Why Procurement Doesn't Catch It

Procurement teams typically engage with telecom at contract negotiation — then move on. The ongoing management of services, billing and usage falls back to IT or Finance, neither of whom have the bandwidth or the specialised knowledge to manage it actively.

Telecom is also a technically complex category. Carriers bundle services in ways that obscure true cost. Billing platforms are deliberately opaque. Contract terms are long and loaded with conditions that shift costs over time.

The result is a category that gets negotiated once and then goes unmanaged for years, even in organisations with sophisticated procurement functions.

A large national NFP engaged CDK after recognising their telecom environment had grown beyond their visibility. The result: $945,000 reduction in annual spend and $167,000 in billing credits recovered. Total commercial impact: $1.11M. No infrastructure changes. No vendor disruption.

What a Structured Review Actually Looks Like

The organisations that recover the most from a telecom review share one thing in common: they started with visibility before making any changes.

That means mapping every active service, mobile, data, voice, internet — to its location, purpose, usage and contract status. Not to make immediate changes. To understand what's actually there.

Once visibility is established, savings become mechanical. Legacy services become obvious. Billing errors surface. Contract misalignments are clear. The mobile fleet review has a baseline.

This process doesn't require a vendor change, a technology project or significant internal resource. It requires an independent eye and the right methodology.

The Question Worth Asking

If you're responsible for telecom spend — whether as a CIO, CFO, or Procurement leader — the question isn't whether there's exposure in your environment.

There almost certainly is.

The question is:

When was the last time someone actually looked?

Not approved the invoice, actually looked at it.
