Performance testing and workflow optimization for Intapp Billstream integrated with Elite 3E at enterprise scale.
Get a Free ConsultationA global law firm was preparing to implement the Intapp Billstream platform, integrated with Thomson Reuters Elite 3E, to streamline billing operations across the firm. During the initial integration process, the platform surfaced critical performance issues, particularly within Proforma workflows, including slow load times, incomplete transactions, and inconsistent front-end behavior.
Without intervention, these issues risked user adoption, billing delays, and a failed go-live. STS was engaged to assess and optimize system performance through a combination of end-to-end performance testing, real-world workflow simulation, and infrastructure and API behavior analysis.
STS helped the firm identify and resolve key bottlenecks. The result: a scalable, stable, and high-performing billing system ready to support enterprise-level demands.
"Our billing platform needed to perform flawlessly under peak load conditions. The performance issues we were seeing during integration put our go-live timeline at risk."
A leading global law firm engaged STS to assess and validate the performance readiness of its enterprise billing platform, powered by Intapp Billstream integrated with Elite 3E. As the organization scaled its operations across multiple jurisdictions, concerns arose around slow responsiveness, workflow delays, and inconsistent user experiences, particularly during high-demand billing periods.
Unvalidated infrastructure configurations posed risks of instability, queuing, and downtime, especially during peak billing periods.
Testing revealed latency issues across core billing actions. Proforma Balance took 2-3 minutes per operation. Proforma Workflow took 15-20 seconds per action. These delays directly impacted user productivity and billing workflow completion.
Simulated testing with 63+ concurrent users surfaced key challenges: data saves took over 40 seconds to load. Backend services became strained due to excessive API chaining, degrading responsiveness across the platform.
STS delivered structured load and performance testing to evaluate the readiness of the client's Billstream billing platform, integrated with Elite 3E, for enterprise-wide deployment. By simulating real-world workflows, measuring backend latency, and validating concurrency at scale, STS identified and resolved critical performance bottlenecks prior to go-live.
STS used Playwright and JMeter to simulate up to 400+ concurrent users interacting with core Billstream workflows, including Proforma generation, Billstream execution, and multi-page navigation.
Our findings revealed that performance issues affected multiple layers of the billing experience. By optimizing Proforma workflows, we were able to:
STS generated targeted technical recommendations to improve overall system posture.
Real billing workflows validated at enterprise-scale concurrency
Reduction in latency for key billing workflows
System stability achieved during peak load testing
Validated the system for 400+ concurrent users executing real billing scenarios
Delivered a stable foundation for firm-wide rollout, reducing the risk of billing disruption during peak usage
Resolved delays in core billing actions such as Proforma approvals and adjustments
Achieved up to 90% reductions in workflow latency, significantly improving turnaround time for billing teams
Identified and resolved bottlenecks that could have affected data accuracy and user confidence
Successfully supported the firm's first integrated system test, confirming the platform's ability to handle enterprise-scale billing workflows
STS built an automation framework from scratch that eliminated our manual regression bottleneck. The quality and speed of their delivery set a new standard for how we approach testing at scale.
