How a Legal Tech Firm Cut 64% of Auditing Costs on Calls with AI Agents

Overview

A leading legal tech company partnered with StackAI to automate the auditing of external communications, cutting QA costs by 64%, reducing operations team workload by 92%, and scaling oversight to 100,000+ calls per month. With no need to expand their technical team, the company launched a highly secure, AI-powered system that ensures data privacy while boosting both accuracy and scale.

"StackAI transformed every step in our quality control process, making it simple to implement and scale AI systems. We can process 10 times more calls and messages, with a higher degree of accuracy, and more cost-effectively."

The Challenge: Scaling Audits Across Voice and SMS Communications

Despite having a sophisticated CRM, this company’s operations team was bogged down by the manual process of auditing phone calls and text messages. Transcribing calls, applying rules, and evaluating quality was both time-consuming and error-prone. Audits consumed massive amounts of time, introduced inconsistencies, and covered only a fraction of all communications, leaving big gaps in oversight and risking non-compliance.

They needed a way to automate quality control without sacrificing precision, security, or scalability, and asked StackAI to help lead the charge. 

The Solution: Secure, AI-Powered Auditing With StackAI

The company was thrilled to use StackAI’s no-code platform to build a multi-step AI system for communications audits. This assistant was designed to transcribe, evaluate, and classify both voice calls and SMS messages using secure, high-performing AI models.

First, phone calls were transcribed using Deepgram’s audio-to-text models, enabling accurate capture of every conversation. Then, an Anthropic LLM hosted securely in AWS Bedrock analyzed the content against internal quality standards, determining compliance, professionalism, and tone.

The system was packaged in a batch-processing interface that allowed hundreds of calls and messages to be uploaded and analyzed at once. This gave the operations team powerful automation without requiring technical expertise, and ensured maximum data privacy at every step.

50% Fewer Errors. Faster, Smarter Audits at Scale. 

StackAI reduced the firm’s audit turnaround time from days to hours. What once took 14 days now takes just 14 hours for voice, and SMS auditing dropped from 3 days to 3 hours. Overall time spent on QA fell by 92%, while error rates dropped by 50%.

Thanks to AI agents, the company has scaled its audit scope dramatically, analyzing 100,000+ calls per month without hiring additional staff. The financial upside was just as impressive: with over $60K in monthly cost savings, the company improved oversight while cutting operational expenses.
