Revenue Assurance in Practice: How TEOCO Helps CSPs Protect and Recover Revenue

An Interview with Fadila Boumaza, VP – Business Assurance Services at TEOCO

As Communications Service Providers (CSPs) continue to navigate complex networks, legacy systems and evolving business models, revenue assurance has become more critical than ever. In this Q&A, Fadila Boumaza, VP of Business Assurance Services at TEOCO, explains what revenue assurance really entails today, why internal teams often need the support of an experienced external partner and how a holistic, data-driven approach not only uncovers but also prevents significant revenue leakage.

What is Revenue Assurance and why is it so important?

Revenue assurance is a business function focused on ensuring that every product and service delivered to the telco’s customer is billed accurately, completely and on time. In telecom, this involves a combination of processes, controls and tools designed to make sure what is sold is ultimately realized as revenue.

Depending on the organization, revenue assurance may sit within finance, billing, audit or compliance. The structure can vary from company to company, but the objective remains consistent—ensuring that services delivered align with contractual intent and are correctly monetized. Given the complexity of telecom operations, even small gaps across the value chain can result in significant revenue leakage.

What Revenue Assurance services does TEOCO offer?

TEOCO provides revenue assurance services through two models. The first is a contingency-based engagement, where we work as an extension of our client’s internal team. In this model, the client typically performs its own initial reviews and TEOCO follows up as a backstop, by analyzing the same data to identify issues that may have been missed. Compensation is tied directly to validated and recovered revenue, which makes the model fundamentally risk-free for our clients. TEOCO is only paid when errors are identified, validated, successfully corrected and the revenue actually materializes in our clients’ accounts receivable. This creates a strong alignment of incentives, because our clients are not paying for reports or recommendations, but investing in outcomes. If no recoverable revenue is found, there is no financial downside.

The second model is a managed service approach. In this scenario, TEOCO becomes the first line of review, reviewing billing and conducting the initial analysis on behalf of the client.

How do TEOCO’s Revenue Assurance experts help CSPs save money?

We partner closely with our clients to help them achieve their revenue and cost assurance objectives. This means ensuring that every product and service sold is billed correctly.

If CSPs already have Revenue Assurance teams, why do they bring in TEOCO?

Most of our clients already have internal teams that understand their own systems and focus on reviewing specific parts of the revenue stream. What differentiates TEOCO, not only from our clients’ internal teams but also from its competitors, is the depth and breadth of experience we bring across multiple telecom domains, including wireless, wholesale, wireline, consumer and carrier services.

We combine this broad industry perspective and domain knowledge with strong technical capabilities, working alongside highly skilled specialists who apply advanced algorithms and statistical models to deliver the best possible outcomes. Beyond identifying revenue issues, we also help our clients understand the underlying root causes, enabling them to put permanent corrective measures in place. Finding revenue gaps is valuable but preventing them from recurring is even more crucial. It is this accumulated, cross-industry experience and fresh perspective that truly sets us apart and allows us to add long-term value to the organizations with whom we partner.

What data sources do you typically analyze?

We analyze the entire revenue value chain from end to end. This includes contracts, quotes, inventory, ordering systems, provisioning data, billing platforms and supporting processes such as commissioning and activation.

Significantly, we do not rely solely on billing outputs. We go back to source systems to ensure that what ultimately appears on the customer’s bill accurately reflects contractual intent and service delivery.

How do you balance automation with human expertise?

At present, TEOCO provides its clients with access to our systems and tools–BillTrak and Claim Center. We also leverage a proprietary set of internal tools and practices to support our work. From a technology standpoint, we use a range of software to ingest data, cleanse it and match it across multiple sources to establish a solid baseline for analysis. These tools allow us to work efficiently and reach results more quickly.

Building upon that foundation, we apply several analytical methodologies, including statistical techniques, to break down the data and determine where our efforts should be focused first. This prioritization enables us to surface issues faster, particularly in areas that may not be immediately visible to the client. While many teams tend to concentrate on common problem areas, such as trend analysis or recently implemented contracts, we go deeper by examining the underlying revenue base as well as new products and services. This broader approach allows us to assess a much larger portion of the overall revenue stream.

What roles do AI and machine learning play in your revenue assurance work?

Traditional revenue assurance tools rely heavily on rule-based validations, which are effective for identifying known or typical issues, but they are not as effective for discovering new or unusual patterns.

We are increasingly incorporating AI and machine learning techniques to support anomaly detection and pattern recognition. Many of our tools now have AI capabilities built into them, including the use of Large Language Models (LLMs) within several applications. These models help our auditors set up new workflows quickly by offering guidance, such as which algorithms to apply and which analytical approaches are best suited for a particular task.

Importantly, sensitive data is not sent to the cloud or to any publicly available LLMs. Instead, we leverage these AI advancements within our controlled environments to improve efficiency and support more effective decision-making.

Tell us about your team and their experience.

Successful revenue assurance professionals typically have broad telecom experience, spanning areas such as network operations, billing, finance, ordering and contract management. They also bring strong analytical skills, technical aptitude and a high degree of curiosity.

This combination is rare and difficult to find. At TEOCO, we invest heavily in developing these capabilities. Our approach focuses on pairing newer team members with experienced professionals, while also giving them broad exposure across different areas of business so they can progress quickly up the learning curve.

One of the challenges in the industry today is that deep expertise in traditional Time Division Multiplexing (TDM) technologies is becoming increasingly rare and many CSPs are feeling the impact of that skill shortage as they transition away from legacy platforms. Our experience in this area has been especially valuable in helping clients bridge that gap, supporting them as they move from older technologies onto newer ones.

Do customers benefit from knowledge transfer when working with TEOCO?

Absolutely. Knowledge transfer is one of the most significant benefits our clients gain. We walk through our findings, explain the root cause and discuss how issues can be addressed. Many clients implement new controls, adjust processes and educate their internal teams based on what we uncover. Over time, they apply these learnings to other areas of their business.

Can you share an example of a major revenue leakage issue you identified?

I will share an example that went unnoticed for years—yet was quite simple in its origins. A government customer received highly favorable pricing for products and services from one of our clients. As part of a periodic contract renegotiation, new pricing terms were agreed upon. The instructions were to take the existing rates and apply an increase percentage. That directive was executed exactly as specified.

However, no one validated that the underlying base rate itself was correct. So, the percentage increase was applied accurately, but starting rate was wrong, resulting in a seven-figure monthly revenue leakage. When we reviewed the case, it became clear that the mechanics of the change were handled correctly. But the foundation it was built on was flawed.

There are other examples that may appear straightforward but are more complex in practice, including cases where system configurations or rule interpretations create issues. In wireless operations, for instance, there are strict rules governing when insurance coverage for a handset or device should apply. Differences in how those rules are interpreted or implemented at the retail level can end up costing the company significant amounts of money.

What measurable revenue assurance outcomes do CSPs typically see?

Clients typically see meaningful revenue recovery, improved billing accuracy and stronger controls that reduce future leakage. Just as importantly, they gain greater visibility into systemic issues and the confidence that their revenue streams are being managed proactively rather than reactively.

Any final thoughts?

One of the most important things to understand about TEOCO is that our success is directly linked to our clients’ success. We are not paid for recommendations or reports; we are paid when our clients recover revenue and achieve real bottom-line results.

That alignment fosters true partnership and long-term relationships. In many cases, we’ve worked with our clients for years, becoming a trusted extension of their teams as their networks and business models continue to evolve.
