It’s used to:
- Find out if there are any overcharges or billing issues
- Find out whether your suppliers are following the terms of your contract •
- Find out how to get the most out of your wireless, broadband, and phone plans
- Monthly costs can be decreased without compromising service.

Why Most Businesses Overpay for Telecom
Telecom billing is complex by design. Here’s why many businesses waste thousands every year:
- Unused lines: Services no longer in use but still being billed
- Billing errors: Incorrect charges, duplicate services, or misapplied rates
- Outdated contracts: Paying legacy rates far above current market pricing
- Inefficient usage: Paying for higher data or voice limits than needed
- Poor invoice management: No central system or team verifying charges
A proper audit brings transparency and control to this often-mismanaged area.

Should You Use a TEM Provider or Do It In-House?
TEM (Telecom Expense Management) providers offer tools and expertise to automate and manage telecom audits at scale.
When to Choose a TEM Provider:
- Large enterprises with complex telecom environments
- No dedicated in-house IT/finance resource
- Need continuous monitoring and analytics
When to Go In-House:
- Smaller companies with 1–3 vendors
- Limited budget for external services
- In-house expertise in finance and telecom billing
Many companies start with a one-time third-party audit and then build an internal process afterward.
Real-World Example: How a Company Saved 32%
A mid-sized SaaS company in Chicago conducted a telecom expense audit and discovered:
- $8,200/year billed for unused analog lines
- $1,500/month in mobile overages from outdated corporate plans
- Duplicate invoices for a cloud voice service
Total savings: $38,000+ annually by renegotiating contracts and streamlining services.
Conclusion: Telecom Expense Audit
Performing a telecom expenditure audit might help you save money and manage your organisation more efficiently. You may enhance vendor relations, cut costs, and reinvest in growth by evaluating telecom bills and contracts on a regular basis, regardless of how many locations you handle.
