Technology Expense Management
Stop Overpaying for Business Technology
Key Takeaways
Technology expense management (TEM) is the disciplined audit of telecom and technology spend: circuits, SD-WAN, UCaaS, mobile, and the contracts behind them. ObsidianX runs a human-led, vendor-neutral TEM practice that finds billing errors, recovers refunds, and renegotiates contracts, then helps you capture the savings. Most businesses save 15 to 30 percent, and the audit costs nothing upfront: the findings are yours either way.
Most businesses overpay for telecom and technology by 15 to 30 percent through billing errors, unused services, and contracts nobody re-benchmarks. Our human-led TEM practice audits every line item, recovers what you are owed, and renegotiates against live pricing from 250+ suppliers.
What is technology expense management? The 2026 definition
TEM started as telecom expense management: auditing phone and circuit bills. The 2026 version is broader because the spend is broader. A real technology expense management program covers fixed circuits (DIA, broadband, legacy copper), SD-WAN and MPLS transport, UCaaS and CCaaS seats, managed network services, mobile and wireless fleets, and the cloud connectivity charges attached to all of it. The discipline is the same across every category: match what you are billed to what you actually use, what you actually contracted, and what the market actually charges today.
The gap between those three numbers is where the money is. Industry audits consistently find that 7 to 12 percent of enterprise telecom invoices contain errors, overcharges, or non-contracted services, and that another 20 to 30 percent of inventory is unused or underutilized services still billing every month. Left alone, the errors compound: published studies put cumulative waste at 12 to 18 percent of annual spend.
There are two ways to attack it. Buy a software platform and staff the work internally, or bring in an expert-led practice that does the analysis and the execution. ObsidianX is the second kind: human-led, engineering-backed, and vendor-neutral. We find the savings, then we help you capture them through disputes, renegotiation, and consolidation, because a finding that never gets executed is worth exactly nothing.
Why most companies overpay: what we actually find
| What we find | How it happens | How common |
|---|---|---|
| Orphaned services still billing | Cancelled circuits and lines keep invoicing until someone disputes them | 15 to 25 percent of audit findings; 3 to 7 percent of enterprise lines |
| Contract rates never applied | Carrier systems default to retail rates after a renewal or migration | 12 to 20 percent of findings; one bad renewal can hit hundreds of lines at once |
| Expired promos that never reverted | Promotional pricing lapses and billing never falls back to the contracted rate | 54 percent of expired promotional rates fail to revert (industry-reported) |
| Volume tier miscalculations | Usage crosses a commitment tier but the bill never rerates | 42 percent of volume-based agreements show tier errors (industry-reported) |
| Tax and jurisdiction errors | Services taxed for the wrong state, city, or regulatory regime | 10 to 15 percent of findings |
| MACD billing mistakes | Moves, adds, and changes billed at wrong rates or double-billed | 8 to 12 percent of findings |
| Duplicate charges | The same service billed twice after renames or system migrations | 5 to 10 percent; one documented case ran $8,200 a month for seven months |
Then there is the auto-renewal trap, which is a contract problem rather than a billing error. Most carrier agreements renew automatically unless you object inside a notice window, commonly 60 to 90 days before term end. Miss the window and you are locked in at rates nobody re-benchmarked, often with promotional discounts quietly expired. Your renewal calendar is your leverage calendar, and carriers count on you not keeping one.
The ObsidianX TEM process
- 1.Invoice and contract collection. Two to three months of invoices per vendor, every contract and amendment, and signed Letters of Agency so carriers release the service records they otherwise keep to themselves.
- 2.Inventory validation. Every circuit, seat, number, and device tied to a real location and a real user. This is where orphaned services surface, and there are almost always orphaned services.
- 3.Rate and usage analysis. Billed rates against contracted rates against actual usage, line item by line item, across every invoice.
- 4.Market benchmarking. The same services priced through our supplier network of 250+ providers, so the comparison is against live market rates rather than last cycle's contract.
- 5.Savings and refund identification. A findings report that separates forward savings from recoverable historical overcharges, with dollar figures on each. The report is yours whether or not you go further.
- 6.Renegotiation support. We run the competitive process at your renewal windows and make the incumbent compete. This is where findings turn into signed savings.
- 7.Consolidation. Overlapping vendors rationalized and invoices consolidated where it genuinely helps, the way HomeBoy Industries went from a patchwork of circuits to a single invoice.
- 8.Ongoing monitoring (optional). A quarterly re-audit cadence that keeps corrected rates corrected, because carrier billing has a way of drifting back.
What does TEM save? A realistic ROI model
| Monthly technology spend | Typical savings range | Typical first-year impact |
|---|---|---|
| $10,000 | 15 to 30 percent | $18,000 to $36,000 |
| $25,000 | 15 to 30 percent | $45,000 to $90,000 |
| $50,000 | 15 to 30 percent | $90,000 to $180,000 |
| $100,000 and up | 15 to 30 percent | $180,000 to $360,000 and up |
Read the ranges honestly. 15 to 30 percent reflects what we typically find; industry programs report 20 to 35 percent first-year reductions and 5 to 10x ROI at enterprise scale, but every estate is different. Recently renegotiated contracts and clean inventories land at the low end or below it. Estates that have never been independently audited, carry legacy copper, or grew through acquisition sit at the high end. First-year impact can also include one-time refund recoveries, which are additive to the ranges above.
Want to know where your estate falls? The audit is free, human-led, and vendor-neutral. If we find nothing, you get independent confirmation that your spend is clean, which is worth having before your next renewal.
TEM software vs human-led TEM
An honest comparison, because the platforms are real tools. Tangoe, Calero, Brightfin, and similar systems process invoices at scale, centralize inventory, and flag anomalies, and large enterprises with dedicated TEM staff get real value from them at roughly $1 to $5 per line per month. What a platform does not do is dispute the charge, run the RFP, or sit across from the carrier at renewal. Somebody still has to execute, and at most platform customers that means 2 to 3 internal staff.
| Consideration | TEM software platform | Human-led TEM (ObsidianX) |
|---|---|---|
| What you buy | A software license, roughly $1 to $5 per line per month | An audit and execution practice with engineering support |
| Who does the work | Your team, typically 2 to 3 dedicated staff | Our analysts and engineers |
| Negotiation | Data to support your own negotiation | We run the competitive process for you |
| Refund pursuit | Anomalies flagged for your team to dispute | We file and chase the disputes |
| Cost model | Subscription due regardless of findings | Nothing upfront; supplier-compensated at direct-equivalent pricing |
| Best fit | Large enterprises with staffed TEM programs | Mid-market and larger teams that want outcomes, not another tool to operate |
It is not either-or. If you already run a platform, we work alongside it: the software surfaces the data, and we turn the flags into captured dollars. If you do not, you get the outcome without buying and staffing a system.
What ObsidianX audits
| Spend category | What we look for |
|---|---|
| Telecom circuits (DIA, broadband, PRI/SIP, copper) | Orphaned circuits, retail rates on contracted services, POTS lines with costs climbing 10 to 30 percent a year |
| SD-WAN and MPLS | Overlapping transport, EPL and Metro-E circuits doing work commodity internet can do, license tiers that no longer match the site count |
| UCaaS and CCaaS | Seats for departed employees, feature bundles never activated, per-seat rates that ignore your real volume |
| Managed network services | SLA credits never claimed, devices billed after decommission, scope creep against the original statement of work |
| Mobile and wireless | Zero-use lines, wrong pooling structures, device installments running past payoff |
| SaaS and cloud connectivity | Duplicate tools across departments, connectivity charges nobody maps to circuits, auto-renewed agreements no one re-priced |
What disciplined audit work delivers: HomeBoy Industries
HomeBoy Industries ran 10 Los Angeles locations on a patchwork of circuits that included $1,100 per month of EPL and Metro-E doing work commodity internet could do, with no one invoice showing the whole picture. The audit-and-consolidation work that followed, inventory, benchmark, redesign, consolidate, produced $1,509.48 per month in verified savings, $18,113.76 per year, on a network that came out more resilient than it went in, with every circuit on a single invoice. That is what TEM looks like when it ends in execution instead of a report.

We scrutinize every line item across all telecom invoices to find discrepancies, billing errors, and redundancies that others miss.
Refund recovery
We fight to recover funds you have historically overpaid due to carrier billing errors, not just stop future leaks.
Contract optimization
Market data from thousands of deals lets us renegotiate terms and align your contracts with current competitive rates.
POTS line replacement
Copper line prices are climbing astronomically as carriers sunset POTS. Wireless replacements for fire alarms, elevators, and fax lines commonly save up to 60 percent.
Hidden fee elimination
Regulatory recovery fees, administrative charges, cramming, and third-party billing: we identify illegitimate charges and eliminate them.
Enterprise leverage for every business
We bring Fortune 500 grade auditing to SMBs, leveling the playing field against major carriers.
Where it pays off
Pre-renewal contract audit
Before you auto-renew, we benchmark your rates and make the incumbent compete. Renewal time is maximum leverage.
Multi-location bill consolidation
Dozens of invoices across locations hide duplicate services and orphaned lines. We inventory, clean up, and consolidate.
POTS sunset planning
Copper retirement is raising analog line costs 10 to 30 percent a year. We migrate life-safety and fax lines to compliant wireless alternatives.
Post-merger telecom cleanup
Acquisitions leave overlapping contracts and services. We rationalize the combined estate and capture the synergy on paper.
Perfect for
- CFOs and controllers who have never had telecom invoices independently audited
- Multi-site businesses with carrier bills nobody fully reads
- Organizations still paying for copper POTS lines
- Anyone within 12 months of a major carrier contract renewal
Technology Expense Management in your industry
Frequently Asked Questions
Questions buyers actually ask about technology expense management, answered plainly.
How much can telecom expense management save my business?
Most businesses save 15 to 30 percent on telecom costs through bill auditing, contract renegotiation, and eliminating unused services. The Museum of Latin American Art cut $475.11 per month ($17,103.91 over the contract) while doubling bandwidth and getting a new phone system.
What is included in a telecom bill audit?
A comprehensive review of all telecom invoices, contracts, and services to identify billing errors, unused lines, hidden fees, and optimization opportunities, benchmarked against current market rates. ObsidianX also pursues refunds for historical overbilling where carriers made errors.
How long does a telecom expense audit take?
The initial assessment takes 1 to 2 weeks once we have copies of your invoices. Full implementation of savings recommendations, including any renegotiation or service changes, typically takes 30 to 60 days.
How much does telecom expense management cost?
With ObsidianX, nothing upfront. Many TEM providers charge licensing fees, per-line rates, or a percentage of savings, but ObsidianX is compensated by suppliers at the same pricing you would pay going direct, and audit findings are yours regardless. If we find nothing, you have lost nothing but gained independent confirmation that your telecom spend is clean.
Should I manage telecom expense management in-house or outsource it?
Most businesses lack the time and cross-carrier billing expertise to audit invoices in-house, and dedicated TEM software still requires someone to interpret and act on the data. Outsourcing to ObsidianX costs nothing upfront and comes with 20+ years of carrier billing experience, so it typically outperforms an internal effort unless you already have a dedicated telecom analyst on staff.
What does a TEM engagement cost compared to other providers?
Industry pricing runs $1 to $5 per line per month for software platforms, $2 to $15 per line for managed TEM services, or contingency fees of 20 to 50 percent of recovered savings. ObsidianX charges nothing upfront: we are compensated by suppliers at the same pricing you would pay going direct, and the audit findings belong to you regardless of what you decide to do with them.
Is TEM worth it for a smaller technology budget?
The sweet spot is roughly $10,000 and up in monthly technology spend, especially across multiple sites or carriers, where errors and orphaned services hide easily. Below that, findings still exist but are smaller. Because our audit is free, the question costs nothing to answer: a clean audit is independent confirmation your spend is tight, which is worth having before your next renewal.
How is ObsidianX different from TEM software platforms like Tangoe or Calero?
A platform is a tool: it processes invoices and flags anomalies, and your team does the disputing, negotiating, and cleanup, typically 2 to 3 dedicated staff at large enterprises. ObsidianX is a human-led practice: our analysts and engineers do the analysis and the execution, including renegotiation and consolidation. If you already run a platform, we work alongside it and turn its flags into captured dollars.
What data do you need to start a technology spend audit?
Two to three recent months of invoices from each carrier and vendor, your current contracts and amendments, and a signed Letter of Agency so carriers will release service records to us on your behalf. With those in hand, the initial assessment takes 1 to 2 weeks.
Can you recover money we already overpaid?
Yes. Where the audit finds carrier billing errors, we file and pursue the disputes, and carriers typically honor lookbacks of 6 to 24 months depending on the contract and tariff. Historical refunds are additive to the forward savings from corrected rates and removed services.
