What Is Telecom Expense Management (TEM)?
Telecom Expense Management (TEM) is the process of managing, analyzing, and optimizing an organization’s telecom and mobile services, including service inventory, contracts, usage, invoices, expenses, and payments. TEM helps businesses identify billing errors, control unnecessary spending, and improve visibility into telecom costs.
When companies face pressure to reduce costs as margins get squeezed, one of the areas that often faces scrutiny is mobile phone service. Mobile operators are notorious for making billing and service plans complicated and continuing to charge premium rates when lower cost alternatives are available. Some companies even consider eliminating mobile service altogether due to the cost and complexity of managing the service.
The financial calculation that goes into this decision is often more nuanced than just “we pay X, let’s get rid of that cost.” Mobile services are an essential part of modern business both for customer accessibility and the flexibility to work from anywhere. Companies that have offered company-paid service in the past are loath to totally eliminate the benefit as employees will rightly see this as a pay cut and be less likely to respond outside of office hours. Businesses often arrive at the compromise solution of allowing employees to expense their personal mobile service.
While this may seem like the best of both worlds – employees can pick the service they want and the company doesn’t have to manage it – that approach has hidden costs that companies often overlook. I’ve done a quick calculation of the typical time and effort required to process an expense report:
$49 per month just to process the expense report! And that’s on top of whatever the reimbursement is.
Why Expensing Mobile Services Can Cost More Than Expected
Employee mobile reimbursement can shift costs rather than eliminate them. A BYOD expense model may require finance and HR teams to manage reimbursement policies, employee claims, approvals, exceptions, tax treatment, and payment records. It can also reduce the company’s visibility into mobile service inventory and usage.
A centralized mobility management model can instead combine service procurement, employee eligibility, billing, expense controls, usage visibility, and cost allocation in one workflow. Modern TEM platforms also use automation and analytics to identify unused services, billing anomalies, and opportunities to optimize mobile spend.
BYOD vs. Company-Paid Mobile Service vs. Managed Connectivity
Companies generally have three approaches to employee mobile services:
- Company-paid mobile service: The company purchases and manages mobile plans directly. This provides stronger control and visibility but requires internal administration.
- BYOD with employee reimbursement: Employees use personal plans and submit expenses. This reduces direct service administration but introduces reimbursement processing and can limit centralized visibility.
- Managed connectivity: A centralized platform manages mobile plans, billing, usage, policies, and employee connectivity while reducing manual administration.
The right model depends on workforce size, mobility requirements, reimbursement policies, security needs, and the level of cost and usage control the company requires.
Service Comparison Business Case
When these processing costs are added to the overall spend, the business case for eliminating company-provided service is eroded. But what if there was a solution that provided the cost savings, eliminated the hassles of dealing with operators and provided employees with the freedom to select any of the 3 major operators? Read on and see what the iSimplexity solution can provide.
Let’s take a look at a 100 person company and assess how the business case on the various models pencils out…
Background & Assumptions
Our company of 100 people has one person fully dedicated to managing the mobile service, dealing with employee devices, etc. Let’s say that person’s salary is $65,000, so a fully loaded salary + benefits would be $84,500. By moving to a BYO plan and letting employees expense the service, the company could eliminate that position and save the $84K.
A company with 100 lines of service should be able to achieve a 20% discount over standard consumer plans. The typical unlimited consumer plan is $65, so the company would pay $52, a savings of $13 per line per month.
What Modern Mobile Expense Management Should Cover
A modern mobile expense management program should cover more than reimbursement processing. Key areas include:
- Inventory visibility: Know which users, devices, SIMs, and services are active.
- Usage monitoring: Identify underused, unused, or unusually expensive services.
- Invoice validation: Compare billed charges against contracted services and expected usage.
- Cost allocation: Assign mobile expenses to employees, departments, projects, or business units.
- Policy enforcement: Apply company rules for plans, spending limits, reimbursements, and upgrades.
- Lifecycle management: Manage orders, changes, suspensions, replacements, and disconnects.
- Reporting and analytics: Track spending trends and identify optimization opportunities.
This broader approach reflects how modern TEM platforms combine expense management with inventory, usage, invoice, procurement, and cost-optimization workflows.
Here’s the in-house vs expensing comparison:
In-House Option
Annual mobile service – $52/line/mo x 12 x 100 = $62,400
In-house management – $84,500
Total cost – $146,900
Expensing Option
Annual mobile service – $65/line/mo x 12 x 100 = $78,000
Expense Processing – $49.38 x 12 x 100 = $59,256
Total cost – $137,256
Savings of $9,644. And if you had a slightly lower salary for your mobile service manager, the savings would completely evaporate. Not exactly a strong business case.
The Hidden Cost of BYOD Reimbursement
The cost of BYOD reimbursement is not limited to the amount reimbursed to employees. Organizations also need to account for the administrative effort required to review claims, enforce policies, process payments, resolve exceptions, and maintain accurate records.
For larger mobile programs, these activities can become a recurring operational workload. Automating reimbursement rules, approvals, expense validation, and cost allocation can reduce that burden while giving finance and IT teams better visibility into mobile spending
iSimplexity Option
Now what if a company could reduce those overhead costs and still offer the bulk discounted service? With iSimplexity, here’s what the savings would look like:
Mobile Service (Unlimited voice, text, data with 5 GB high speed) – $30 x 12 x 100 = $36,000
iSimplexity Service Fees Platinum Plan – $10 x 12 x 100 = $12,000
Total cost – $46,400
Company cost savings vs in-house plan – $146,900 – $46,400 = $100,500
Company cost savings vs expensing plan – $137,256 – $46,400 = $90,856
Now those are numbers that can make a real difference to a company. When considering alternative mobile service options, take a look at iSimplexity, we might be the best option out there!
A managed connectivity model can combine centralized mobile plan management, billing, usage visibility, policy controls, and expense administration without requiring the company to build and maintain the entire operational process internally.
For example, Spenza provides centralized connectivity management for businesses, including telecom expense management, usage reporting, and cost optimization. The platform is designed to help organizations identify mobile and connectivity waste and manage plans centrally.
The actual savings will vary by workforce size, carrier rates, plan structure, reimbursement policy, and existing administrative costs. Companies should therefore calculate total cost of ownership using their own current mobile spend and operational workload rather than relying on a fixed savings estimate.
From Expense Reimbursement to Telecom Cost Optimization
The bigger opportunity is to treat mobile connectivity as a managed business expense rather than simply an employee reimbursement. A centralized approach can connect mobile inventory, service plans, usage, invoices, and cost controls so finance and IT teams can see where money is being spent and where services can be consolidated or optimized.
Modern TEM platforms increasingly combine invoice management, inventory visibility, usage analytics, procurement workflows, cost allocation, and automated expense controls in one system
