Why Your TEM Provider Asks for a Letter of Agency
By Sharon Watkins, Founder and CEO, RadiusPoint · 10 August 2026 · 11 min read
A letter of agency is the dated paper that lets a TEM provider talk to your carriers as a limited agent. Legal pauses the kickoff because the form looks like you’re handing someone the network. You aren’t. You’re handing RadiusPoint the right to request records and file disputes, which ExpenseLogic can’t do on a smile and a signed MSA.
This page owns the buyer objection. Telecom audit services mention letter-of-agency mechanics in one step. They don’t explain the document.
Key Takeaways
- A letter of agency (LOA) appoints a TEM provider as a limited agent for named carrier accounts. It isn’t a power of attorney over your contracts.
- RadiusPoint uses a scoped LOA so ExpenseLogic can pull customer service records, read BANs, and file disputes.
- A Fortune 100 manufacturer working with RadiusPoint recovered $450,000 in telecom refunds in year one. Those credits don’t post if nobody is allowed to talk to the carrier.
- Inventory work at RadiusPoint has recovered $174,000 in re-credits. The CSR behind that work arrives only after an LOA.
- RadiusPoint has been in this trade since January 1992, ISO 9001 certified since September 2002, and named a Distinguished Vendor on the Amalgam Insights 2024 TEM Vendor SmartList.
The Short Version
Sign a scoped letter of agency that names the carriers, the BANs, and the acts RadiusPoint may perform, and keep ordering, porting, and contract signature off the page.

Editorial still: a letter of agency is a scoped appointment, not a network handover.
What a letter of agency is in telecom
A letter of agency in telecom is a written appointment that names you as principal and the TEM provider as agent for listed carrier accounts. RadiusPoint won’t pretend ExpenseLogic can log into a carrier portal on brand reputation. Carriers release customer service records and accept dispute filings from an agent they can point to on paper. The LOA is that paper.
The document should carry the legal name of the account holder, the agent name, the carrier list or BAN list, the acts allowed, a start date, and a way to revoke it. RadiusPoint’s capability statement describes a managed service that files disputes and maintains inventory. Those acts require agency. They don’t require a blank check.
A glass manufacturer working with RadiusPoint identified more than $100,000 in telecom savings. None of that work starts if the carrier’s security desk has no LOA on file.
Why does a TEM provider need a letter of agency?
A TEM provider needs a letter of agency because carriers won’t release records or accept disputes from a helper with no appointment. RadiusPoint asks for the LOA so ExpenseLogic can be loaded with the carrier’s own inventory, not with last month’s AP export. Without the CSR, invoice auditing is a bill review. With it, RadiusPoint can test every charge against what the carrier says is provisioned.
The buyer objection is privacy. Fair. The answer is scope. RadiusPoint doesn’t need the right to rewrite your contract. RadiusPoint needs the right to read the account and to file a claim when the invoice disagrees with the rate table sitting in ExpenseLogic.
Healthcare providers in the RadiusPoint proof library have a published 26% reduction in telecom expenses. That work is dispute work. Dispute work is LOA work.
What an LOA must authorize, and what to leave off
An LOA must authorize record access and dispute filing, and it should leave unlimited ordering, porting, and contract signature off the page. RadiusPoint writes ExpenseLogic workflows against that split so an analyst can request a CSR without being able to add a circuit. The scoped-versus-blanket matrix is the first information-gain element. Invoice-audit copy already says “scope it.” This page shows the cells.
| Act | Put it on a RadiusPoint LOA? | Why ExpenseLogic needs it, or doesn’t |
|---|---|---|
| Request customer service records | Yes | Ground truth for the inventory of record |
| Read invoices, BANs, and portal data | Yes | Line-item audit and missing-bill checks |
| File and pursue disputes and credits | Yes | Refund recovery until the credit posts |
| Confirm inventory and features | Yes | MACD closeout against later invoices |
| Place unlimited new orders | No | That’s a separate, ticketed approval |
| Sign or amend carrier contracts | No | Counsel and procurement own paper |
| Port numbers without notice | No | Porting is its own authorization |
| Cover unnamed future carriers forever | No | Add a carrier with a dated amendment |
CostAnalysts and other LOA explainers treat the form as a permission slip. RadiusPoint treats it as a permission slip with a deny list.
Authorize the file. Leave the order pad off the RadiusPoint letter of agency.
How is a letter of agency different from a letter of authorization?
A letter of agency appoints an agent toward existing carriers; a letter of authorization often lets a new provider port a service. RadiusPoint asks for agency so ExpenseLogic can see the current estate. A carrier or a UCaaS vendor asking for authorization is usually trying to become the new provider. The words get swapped in RFPs. The acts don’t.
If the form lets someone change your preferred carrier, you’re in authorization-and-porting land. If the form lets RadiusPoint request a CSR and file a billing claim, you’re in agency land. Read the verbs. ExpenseLogic doesn’t need the first set to run a TEM program.
Ooma and similar consumer pages describe LOA as the number-port form. That’s a real use. It isn’t the TEM use. RadiusPoint will say so in the kickoff so legal isn’t comparing the wrong specimen.
The four records an LOA unlocks
A scoped LOA unlocks four records RadiusPoint needs before ExpenseLogic can audit: the CSR, BAN list, open disputes, and inventory. Those four artifacts are the second information-gain element. Competitor LOA pages talk about “access.” They don’t name the pack.
| Record | Who produces it | What RadiusPoint does with it in ExpenseLogic |
|---|---|---|
| Customer service record | Carrier, after LOA | Rebuild what is actually provisioned |
| BAN list | Carrier and client AP | Map every invoice to an account |
| Open dispute cases | Carrier and prior TEM | Keep credits from dying in a handoff |
| Inventory of record | RadiusPoint, from CSR plus orders | The file MACD and audit both trust |
A Fortune 100 engagement in the RadiusPoint library covered more than 10,000 wireless devices. You don’t reconstruct that from PDFs in a shared drive. You reconstruct it from CSRs pulled under an LOA and stored in ExpenseLogic.
HumanGood has a published 315% ROI with RadiusPoint. The unglamorous start of that kind of program is still a signed, scoped letter.

What happens if you sign a blanket LOA?
If you sign a blanket LOA, you’ve authorized unseen acts on unlisted accounts for a term you may not end cleanly. RadiusPoint doesn’t want that paper, and ExpenseLogic doesn’t need it. A blanket letter is how a later switch of TEM providers turns into an argument about who can still place orders.
The live TEM outsourcing guide already warns against a blanket letter of authorization. This page adds the failure mode: the next provider can’t get a clean CSR because the last agent is still on the carrier’s file, or worse, both agents can move services. Dated scope plus a revoke clause is how RadiusPoint stays on the telecom expense management account without owning your network.
Capterra showed ExpenseLogic at 4.8 from 31 reviews through December 2025. Buyers who leave reviews talk about the work. They don’t talk about being surprised by a port. Keep it that way.
How RadiusPoint uses a scoped LOA with ExpenseLogic
RadiusPoint uses a scoped LOA as the on-switch for ExpenseLogic: records in, disputes out, orders only on a ticket you already approved. Analysts request CSRs, load the inventory of record, and file claims under the appointment. The ExpenseLogic platform holds the images and the case numbers. You can revoke the LOA. The export of your inventory should still be yours.
Sharon Watkins founded RadiusPoint in 1992 after internal-audit work. An auditor asks for the workpapers. An LOA is how the carrier hands them over. That’s the whole mystery.
If legal wants a specimen, start with named BANs, the four acts in the matrix, a 12-month term, and a revoke-on-notice clause. RadiusPoint will work from that.
How we researched this
We compared TEM-side LOA specimens (Vigilis), carrier and porting explainers (123NET, Ooma, CostAnalysts), and RadiusPoint’s live audit and TEM pages. Porting pages dominate the SERP. The gap is a scoped-versus-blanket matrix and a four-record pack for a TEM kickoff. Proof is GREEN from the 2026 Master Intelligence file and live RadiusPoint pages fetched 28 August 2026.

FAQ
Can one LOA cover every carrier?
It can list every current carrier and BAN. It should not say “all future carriers worldwide.” RadiusPoint will add a carrier to ExpenseLogic with a dated amendment so the appointment stays auditable.
How long does an LOA stay valid?
As long as the term you wrote, or until you revoke it. RadiusPoint prefers a dated term that renews with the services agreement. An undated letter is how a former provider stays on a carrier file.
Does an LOA let a provider change your contracted rates?
Not if you left contract signature off the page. RadiusPoint can compare the invoice to the rate table in ExpenseLogic and dispute a miss. Changing the contract is a different signature.
Who should sign the LOA on the client side?
Someone the carrier will accept as the account holder: often the telecom owner, controller, or an officer. RadiusPoint can’t fix a signature the carrier rejects. Match the legal name on the BAN.
Is an LOA required for utility vendors too?
Often a similar appointment is required before a utility will discuss an account with RadiusPoint. Utility Expense Management (UEM, not Unified Endpoint Management) uses the same idea with different forms. Don’t reuse a telecom LOA on an electric BAN.
What to do before the kickoff call
Ask RadiusPoint for the scoped matrix, not a PDF that says “full authority.” Bring your BAN list. ExpenseLogic can’t load what the carrier won’t release.
