Challenge

Struggling with inefficient manual invoice processing processes that were slowing growth and increasing operational costs. Their primary concern was contract review accuracy.

The challenge

This corporate law firm had reached a breaking point with their manual invoice processing process. With 10-50 attorneys managing daily legal operations, the team was spending an average of 25+ hours per week on repetitive invoice processing tasks that added no strategic value. The workload was unsustainable, and errors were becoming more frequent as volume grew. The consequences extended beyond wasted time. In their legal business, delayed invoice processing created a cascade of downstream problems — missed deadlines, frustrated stakeholders, and data quality issues that undermined decision-making. The team had tried hiring additional staff, but the cost was prohibitive and training new employees on their complex legal processes took months. They needed a solution that could handle their current volume and scale with their growth, without requiring a proportional increase in headcount.

The solution

The team selected Arahi AI to automate their legal invoice processing workflow end-to-end. Implementation began with connecting their core tools — Clio, Google Drive, and Gmail — to the Arahi AI platform. Using the no-code builder, they configured AI agents that replicate their best-performing team member's decision-making process, but at machine speed and consistency. The AI agents handle every step of the invoice processing process: receiving incoming requests or triggers, analyzing the context using legal-specific rules, making intelligent routing decisions, executing the core actions, and notifying the right stakeholders. What previously required 45+ minutes of manual work per instance now completes automatically in under 2 minutes. The agents also learn from corrections, continuously improving their accuracy. The team connected Slack for tracking and reporting, giving leadership real-time visibility into invoice processing performance metrics for the first time.

Implementation

4 AI agents deployed in 3 hours.

1. Connected legal tools to Arahi AI

   Integrated Clio, LawPay, and DocuSign with Arahi AI using pre-built connectors — no API keys or custom code required. The team verified data flow between systems in under 15 minutes.

2. Configured AI agent business rules

   Defined the legal-specific rules for invoice processing: scoring criteria, routing logic, escalation thresholds, and exception handling. The team used Arahi AI's visual rule builder to translate their existing process into automated workflows.

3. Tested with live legal data

   Ran the AI agents on a week's worth of historical invoice processing data to validate accuracy and identify edge cases. Made minor adjustments to scoring weights and routing rules based on the results.

4. Launched and monitored

   Deployed the AI agents to production with the entire team notified via Slack. Monitored the first 48 hours closely, confirming high accuracy before reducing oversight to weekly reviews.
