Advisory · Telecom Cost Reduction
Lower telecom costs and recover what you have been overbilled.

A client-first model
An independent advocate, not a carrier sales rep.
Carrier representatives and resellers are paid on commissions and upsells. NSI is fully independent: every recommendation we make is based only on your organization's interests, with no vendor incentive behind it.
We serve as your single point of contact across all carriers, vendors, and utility providers, keeping communication consistent and vendors accountable to your goals.
What we review
Every invoice, contract, and service, reconciled line by line.
Billing error recovery
We find and document overcharges, duplicate billing, misapplied taxes and fees, and unapproved line items, then manage every claim through to refund.
Rate and service optimization
We benchmark your services against the market and negotiate lower-cost, more efficient options with current or new vendors.
Inventory and usage assessment
A complete inventory of active circuits, lines, and services shows what is used and what can be eliminated.
Contract analysis and renegotiation
We review contracts for unfavorable terms and renewal risks, and lead renegotiations for better rates and conditions.
How we audit
Modern tools, applied by experienced consultants.
Automation finds errors at scale. Our consultants verify every finding and handle the vendor conversations.
AI-assisted invoice auditing
Software matches every invoice against contract terms, usage, and service inventory.
Call detail record analysis
Usage trends reveal underused voice, data, and mobile services.
Benchmarking and rate comparison
Your rates are compared against industry benchmarks and national carrier pricing.
VoIP and cloud communications review
Hybrid, VoIP, and cloud phone services are optimized, especially where legacy systems remain.
