Line-by-Line Wins: How A Communication Service Provider (CSP) Transformed Network Resale Operations​

Case study cover titled "Line-by-Line Wins," showing how a Communication Service Provider (CSP) transformed its telecom expense operations with AMI Strategies, with $300,000 recovered in the first year.

Client Profile

Acting as a Communication Service Provider (CSP), the client is a managed infrastructure solutions provider that empowers enterprises to modernize, protect, and manage their mission-critical applications and data using its resilient cloud platform.

Its portfolio spans cloud, connectivity, and managed security services, delivered under strict compliance frameworks.

We couldn’t allocate cost per line. We had to do it at the whole invoice level, which caused a lot of manual work. If we contracted the client for a year, but we had the circuit for five years, or vice versa, that mismatch would cost us money. We needed the right tools and process to prevent that from happening.”

Challenges

  • Inefficient Cost Allocation
  • Contract Visibility & Validation
  • Dispute Management Overload

Outcomes

The Challenge: Managing Scale

After consolidating multiple legacy business units through a series of acquisitions, the company inherited a vast and complex network inventory across its connectivity operations. By 2023, it faced mounting challenges in cost allocation, contracts, vendor disputes, and billing accuracy.

Inefficient Cost Allocation

Like most accounts payable (AP) systems, the company’s AP platform was not designed to handle the nuances of telecom billing. Multiple cost centers existed within a single invoice, but charges could only be allocated at the invoice level, forcing time-consuming manual work.

Contract Visibility & Validation

The Access Cost Management team sought to verify that circuits had active, in-date contracts to prevent mismatched terms between end-client agreements and carrier contracts, which could result in lost revenue or excess costs.

Dispute Management Overload

Disputes on billing errors, surcharges, and contract terms had become excessive and cumbersome for internal stakeholders. The company needed a knowledgeable team to centralize information and take ownership of disputes.

We needed a team. Instead of growing it internally, we wanted a package where all the information and assistance in one place without having to fight for headcount.”

Objectives: Efficiency, Accuracy, and Scalability

The company set out to optimize its telecom expense management processes with a focus on efficiency, accuracy, and scalability. The goal was to eliminate inefficiencies, strengthen vendor relationships, and create a foundation for sustained operational growth:

Streamline telecom billing and strengthen contract validation to ensure accuracy and alignment with end-client agreements.
Reduce manual workload and minimize late fees by automating key processes and improving timeliness.

Establish a scalable, centralized platform to manage dispute resolution, reporting, and future expansion.

Improve visibility into inventory and vendor relationships to support better decision-making and strategic planning.

The Solution: Partnering with AMI Strategies

In 2024, this Communication Service Provider (CSP)  partnered with AMI Strategies, a leading telecom, technology, and utility expense management provider specializing in cost control, contract compliance, and inventory visibility, to address these challenges. The partnership focused on:

Line-by-Line Allocation

Replacing invoice-level allocation with precise, per-line cost assignment.

Contract Mapping & Validation

Ensuring every circuit was tied to an active contract and matched to the correct client agreement.

Dispute Management

Leveraging AMI’s team to proactively find and resolve billing errors, manage carrier communication, and recover funds.

Unified Visibility & Reporting

Centralizing contracts, costs, allocations, inventory, circuit routing, dispute status, and credits received into one platform for complete transparency and faster decision-making.

The Results

Inventory Cross-Verification

With inventory this large, the company had no reliable way to reconcile what it orders from carriers against what it has committed to its own clients. AMI’s process now cross-checks the two sides circuit by circuit, surfacing mismatches — a line billed for five years against a one-year client agreement, for example — that previously went undetected. That visibility has given the team confidence in its margins as the inventory base continues to grow.

“With the vast amount of inventory we support, being able line up what we order from our carriers to what we have contracted with our clients is critical. it’s been a great growth rate of just knowledge building”

Significant Cost Saving

$300,000 recovered in one year. Disputes covered incorrect billing, double surcharges, taxes, late fees, and premature/ extended billing. In 2025, an additional $100K+ has been recovered by mid-year through AMI-led dispute wins.
“For Disputes, I don’t have to rely on just one set of eyes. I get a team. AMI follows up, they’ll keep tabs, they update me biweekly, which is what I requested. It gives me time back so I can help with internal projects versus digging in details all day.”

$300,000

recovered in one year

Drastic Reduction in Avoidable Fees and Credit Dispute Handling Time

84% reduction in late fees due to efficiencies created in the AMI invoice lifecycle management process, and 50% reduction in time to obtain credits from billing errors.
“Before AMI, disputing billing errors was slow. Now we get them back in half the time.”

Stronger Internal Relationships

Reliable data for budgets, P&Ls, go-to-market pricing strategies, and investor reporting.
“It has definitely reduced friction for our finance team and providing information back to engineers and our NOC to have good, clean understandable information all in one platform.”

Improved Workload & Productivity

Significantly reduced the comapny’s internal workload overseeing this aspect of their product portfolio.

“I don’t have to work 15 hours a day anymore. AMI handles disputes, follows up, and keeps tabs so I can focus on other priorities.”

Better Financial & Operational Visibility

Reliable data for budgets, P&Ls, go-to-market pricing strategies, and investor reporting.
“For our finance team, we can reliably turn over statements to investors or stakeholders or clients. We have real numbers to share with them.”

AMI isn’t just a vendor — they’re part of my team. We talk apples to apples, not apples to oranges, and that makes all the difference.”

Conclusion

Through its partnership with AMI Strategies, this Communication Service Provider (CSP) has transformed a fragmented, siloed environment into a consolidated, streamlined, and data-driven operation. By centralizing inventory, contract validation, cost allocation, and dispute management, it not only saved hundreds of thousands of dollars but also reclaimed time, improved internal relationships, and gained near-complete visibility over its telecom environment.
