Introduction: Navigating the Complex World of Telecom Expenses

In today’s digital-first world, telecommunications services are the backbone of modern business operations. From mobile devices enabling remote teams to cloud-based platforms, the need for reliable infrastructure has never been greater. Yet with this dependence comes a challenge: managing costs and complexities.

Organizations often face opaque billing, unexpected charges, and limited visibility into spending—issues that lead to financial drain and operational inefficiencies.

Telecom Expense Management (TEM) addresses these challenges through a mix of processes, technologies, and services that help control costs and manage assets across wireline, wireless, data, CCaaS and UCaaS. Its goal is not just to cut costs, but to optimize investments, eliminate waste, and keep communications aligned with business objectives. TEM provides a framework for tracking inventories, auditing invoices, and proactively managing the telecom ecosystem.

According to research, the global TEM market is projected to grow from US$ 4.09 billion in 2024 to US$ 4.7 billion in 2025, a 15.1% CAGR. By 2029, it could reach US$ 8.24 billion, fueled by rising mobile adoption, the 5G rollout, and the demand for cost control.

What is Telecom Expense Management?

Telecom Expense Management (often abbreviated TEM) refers to the policies, processes, technologies and services an organization uses to monitor, control and optimize costs associated with telecommunications. Modern TEM programs extend beyond traditional fixed‑line and mobile services to cover data circuits, wide‑area networks, wireless devices, cloud communications, unified communications and collaboration (UC&C), Internet of Things (IoT) connectivity and sometimes software‑as‑a‑service (SaaS) subscriptions.

The Core Components of a TEM Solution

A robust TEM solution is built upon several interconnected core components, each designed to provide a 360-degree view and tight control over an organization’s telecom expenses and assets. These foundational elements work in synergy to ensure effective and efficient management of the entire telecom ecosystem.

• Inventory management: Creating and maintaining a single, accurate repository of all telecom assets (lines, devices, circuits, SIMs, licences, carriers and contracts) and mapping them to users, cost centres and locations. Visibility into what you have is the foundation for optimization.
• Invoice processing and validation: Collecting invoices from every carrier, normalizing data into a consistent format, validating charges against contracts and usage, catching anomalies and disputing errors before payments hit the general ledger. Analysts note that 85 % of invoices contain mistakes, so rigorous validation is essential.
• Contract and vendor management: Tracking contract terms, renewal dates, service‑level agreements, rate plans and discounts to negotiate better pricing and avoid autorenewals. Poorly managed contracts are a primary source of overspending.
• Usage analytics and optimization: Monitoring consumption patterns (minutes, data, messaging), identifying under‑used services or unused devices, right‑sizing plans, enforcing policies (e.g., restricting premium calls or roaming) and reallocating or cancelling unnecessary services.
• Chargeback and cost allocation: Assigning telecom costs to the correct departments, projects or cost centres to increase accountability. Transparent chargebacks promote responsible usage and help leaders understand the true cost of services.
• Lifecycle governance (MACD): Managing moves, adds, changes and disconnects (MACD) processes with approvals and documentation so that employees receive the right services and unused lines are cancelled promptly. Informal or unmanaged MACD processes are a major cause of duplicate charges and unused services.

TEM may be handled in‑house using software tools, outsourced to a managed service provider (sometimes called managed mobility services or MMS) or delivered as a hybrid of technology and expert services. Regardless of approach, organizations should treat TEM as a continuous discipline, not a one‑time project.

Benefits of a Modern TEM Solution

Organizations adopt TEM solutions for many reasons:

1. Cost reduction and visibility: Best‑in‑class programs deliver 15–25 % cost savings across wireless, fixed and UCaaS spend while providing holistic visibility into all telecom and mobility programs.
2. Automation and AI: Modern platforms use AI to normalize and audit invoices, identify underutilized assets and automate provisioning. Predictive models reduce unmanaged spend by 20–30 % and cut manual invoice processing by 80 %, leading to faster return on investment.
3. Governance and compliance: AI‑powered dashboards enable department‑level accountability and policy enforcement. They also support ESG goals by integrating device recycling and e‑waste reporting.
4. Support and productivity: TEM now includes help‑desk services, improving employee productivity and ensuring consistent policy enforcement across BYOD and corporate‑liable models.

Spenza’s article Benefits of Telecom Expense Management solution (TEM) goes deeper into these advantages, illustrating how TEM helps businesses gain control over their telecom environment and avoid surprise charges.

Market trends shaping telecom expense management

Several macro trends are transforming the telecom landscape and driving the need for more sophisticated expense management:

1. Growth of the TEM market: Future Market Insights estimates that the global TEM market will grow from US$5.3 billion in 2025 to US$16.6 billion by 2035, representing a compound annual growth rate of 12 %. Financial management functions will be the largest segment (23.1 %), and managed services will lead the mode‑of‑delivery segment (42.6 %).
2. Rising complexity from hybrid work and cloud: The pandemic‑driven shift to remote and hybrid work accelerated adoption of mobile devices, collaboration tools and cloud communications. Enterprises now manage a mix of fixed lines, cellular plans, voice‑over‑IP (VoIP), videoconferencing subscriptions and as‑a‑service platforms across dispersed teams. As global telecom spending is expected to reach US$1.595 trillion in 2024, controlling spend across these diverse services is increasingly challenging.
3. 5G, IoT and edge computing: Fifth‑generation (5G) networks enable high‑bandwidth, low‑latency connectivity for emerging applications like autonomous vehicles, augmented reality and industrial IoT. Enterprises adopting IoT sensors and smart devices must manage thousands of new connections with variable data usage. TEM platforms need to support metering and policy enforcement for these devices and integrate with IoT management platforms.
4. Convergence of network and cloud expense management: Many organizations are expanding TEM programs to cover cloud infrastructure, software‑as‑a‑service and unified communications, sometimes called technology expense management or XEM. As cloud spend often doubles year‑over‑year, integrating telecom and cloud cost governance helps enterprises optimize across categories and avoid siloed management.
5. Increased adoption of AI and automation: Modern TEM solutions leverage machine learning to normalize invoices, classify services, detect anomalies and predict future costs. Automation can triage invoices, apply policy rules, trigger disputes and suggest optimization opportunities. Vendors offering AI‑enabled features and analytics platforms are differentiating themselves amid a crowded market.
6. Regulatory and security considerations: Industries such as finance, healthcare and government must comply with data‑protection regulations and audit requirements for telecom services. TEM providers increasingly offer secure data handling, encryption and audit‑ready reporting. In addition, geopolitical factors and supply‑chain disruptions raise concerns about vendor risk management, making contract oversight and contingency planning essential.

These trends highlight why enterprises cannot rely on manual spreadsheets or reactive invoice processing. A proactive, automated TEM program supports both cost optimization and strategic planning.

The Relationship Between TEM and Enterprise Mobility Policy

Telecom Expense Management is intrinsically linked with an organization’s enterprise mobility policy. While TEM provides the operational tools and processes to manage telecom costs and assets, the mobility policy sets the strategic rules for devices, security, usage, and reimbursements, including Bring Your Own Device (BYOD) programs. Studies consistently show that a well-defined mobility strategy, coupled with programmatic controls, significantly impacts both cost and productivity, as discussed in our article on The Hidden Costs of Expensing Mobile Services. 

TEM operationalizes these controls at scale, providing auditable processes and data to ensure that the mobility policy is effectively implemented and enforced. This synergy ensures that mobile services, which are often a significant portion of IT spending, are managed efficiently, securely, and in alignment with business objectives. Without a robust TEM framework, even the most well-intentioned mobility policies can lead to hidden costs and inefficiencies.

Why telecom expenses spiral out of control

Many organizations struggle to keep telecom costs in check. Common drivers of overspending include:

• Billing errors and overcharges: Errors are rampant. Gartner research, cited by Upland Cimpl, reports that 85 % of telecom invoices contain mistakes, leading to 12 – 20 % over‑spending each month. Even with improved automation, a 2005 Gartner study found that 80 % of invoices contained errors, and recent estimates put the rate at 15 %. Without systematic validation, these errors compound over time.
• Unused or under‑utilized services: Enterprises frequently pay for lines and devices that have been disconnected or assigned to departed employees but never cancelled. Upland notes that informal MACD processes can lead to charges for disconnected services and duplicate billing. Remote work exacerbates the problem as employees provision additional data plans and collaboration tools without central oversight.
• Contract misalignment and autorenewals: Telecom contracts are complex, with myriad rate plans, discounts, volume commitments and early termination penalties. When contracts renew automatically, companies miss opportunities to renegotiate rates or switch to more cost‑effective options. Lack of a contract repository makes it difficult to track expiration dates and obligations.
• Decentralized purchasing: Different departments may procure telecom services independently, leading to fragmented inventories and inconsistent pricing. Without centralized governance, enterprises cannot leverage volume discounts or enforce standardized policies.
• Lack of visibility and reporting: Many organizations rely on manual spreadsheets or basic accounts‑payable processes that simply pay invoices. Without detailed usage and cost analytics, leaders cannot identify trends, forecast budgets or hold departments accountable.
• Emerging technologies and shadow IT: Employees increasingly adopt new collaboration apps, conferencing platforms and cloud services without IT involvement. These “shadow IT” subscriptions create additional cost centres and data‑security risks.

Addressing these challenges requires more than occasional audits; it demands a systematic, technology‑enabled approach to managing every element of the telecom lifecycle.
