As regulatory pressure and rising drug costs reshape expectations for pharmacy benefit managers (PBMs), real-time data is becoming central to how PBMs build trust and retain clients.

Payers are facing mounting pressure to control pharmacy costs and recent legislation focused on pharmacy benefit management has further narrowed tolerance for delayed or opaque insights. As drug prices continue to rise, PBM clients are asking tougher questions and increasingly expect the ability to identify cost drivers as they emerge, not months later.

In practice, this shift is revealing how quickly meaningful opportunities can surface when timely data is available. In one recent example from RxSense, a real-time analysis revealed that a disproportionate share of pharmacy spend was tied to a single high-cost drug, prescriber and pharmacy. This type of insight would have been difficult to detect through traditional reporting cycles.

Across the PBM industry, clients are still often forced to wait weeks or months for performance data, long after trends have shifted and opportunities to intervene have passed. What was once an operational inconvenience is now a relationship risk. As expectations around transparency continue to rise, timely and accessible insights are increasingly shaping how PBMs communicate with and retain their clients.

Why reporting delays can carry risk

According to a Federal Trade Commission report, the largest PBMs in the U.S. manage nearly 95% of all prescriptions filled, making delayed insight into utilization and cost trends particularly consequential for payers and plans. With a small number of PBMs controlling most prescription volume, delays in traditional reporting remain a common source of frustration, widening the gap between activity and insight.

“Legacy PBM reporting often arrives 30, 60, even 90 days after the fact,” said Ramzi Yacoub, Pharm.D., chief pharmacy officer at RxSense. “That means clients are reacting to problems that have already happened. When information arrives that late, there is very little they can do to manage cost spikes, utilization shifts, or overall patient health.”

Those delays are most visible during onboarding and day-to-day operations. Cost drivers surface late, utilization changes go unnoticed and performance guarantees are often measured only after results are locked in. Over time, limited visibility erodes confidence and increases the risk of churn.

For many PBMs, the challenge is not simply identifying gaps in reporting, changing when insight becomes available. When data is available while activity is still unfolding, the relationship can move from explanation to engagement.

From retrospective reporting to proactive engagement

When performance data is available in near real time, it changes how PBMs and their clients work together. Instead of spending meetings reconciling reports or debating accuracy, conversations can focus on insights, emerging trends and decisions that are still actionable.

“It shifts conversations from retrospective to collaborative and forward-looking,” said Yacoub. “Real-time reporting enables more frequent, lighter-touch check-ins that feel proactive rather than escalatory. The tone becomes less about ‘why did this happen?’ and more about ‘here’s what we’re seeing and what we can do next.’”

That shift is especially important for utilization trends, cost drivers and performance guarantees, where delayed discovery leaves little room to adjust. Seeing issues as they develop allows PBMs to respond earlier, course-correct faster and maintain credibility with clients.

Turning transparency into trust and retention

Timely data is only useful if clients can access it easily. Self-service analytics platforms, such as RxIQ Business Intelligence (RxIQ BI), give PBMs and their clients direct visibility into performance without waiting for periodic reports.

“At RxSense, we give customers full visibility into the adjudication platform and the ability to identify issues quickly and resolve them for their clients,” Yacoub said.

As mentioned in the introduction, RxSense worked with a client exploring whether to become its own PBM. While the client believed it had a strong understanding of its pharmacy spend, real-time analysis revealed that a single high-cost drug with available generic alternatives was driving a disproportionate share of costs, tied to one prescriber and one pharmacy. “They were amazed by how quickly and clearly the opportunity surfaced using real-time analytics,” said Yacoub. “That level of access changes the trust dynamic for the better. Clients no longer feel dependent on us to tell them what is happening. They can see the data for themselves.”

Retention built on visibility

As regulatory pressure increases and pharmacy costs continue to climb, PBM relationships are being tested in new ways. Clients want clarity while changes can still be made, not months after the fact.

Real-time data, transparent reporting and direct access do not eliminate every challenge PBMs face, but they do change how PBMs and clients work together. By replacing delayed explanations with shared visibility, PBMs can strengthen trust, improve collaboration and deliver results that clients can clearly see.
