Inspiration
Enterprise AP (Accounts Payable) teams lose over $300B annually to invoice fraud, ghost line-items, and rate drift. While the market is flooded with generic "AI invoice parsers," CFOs fundamentally cannot trust them: an LLM with a 95% accuracy rate is a catastrophic failure in corporate treasury, where a 5% hallucination rate can leak hundreds of thousands of dollars.
We built LedgerGuard on a contrarian architectural premise: Never let an LLM do financial arithmetic. Instead, decouple strict mathematical auditing from contextual diplomacy. Deterministic rules freeze the money; autonomous agents negotiate the dispute.
What It Does
Rather than just passively detecting spend, LedgerGuard reconstructs the entire Agent Economic Trace—validating contractual authority, enforcing sub-2ms deterministic reconciliation, locking liquidity on Dodo Payments rails, and piping immutable audit evidence into Neatlogs.
- Deterministic 3-Way Audit: Ingests vendor invoices against Purchase Orders (POs) and executes strict mathematical verification in sub-2ms (1.46 ms) with zero hallucinations.
- Instant Liquidity Circuit-Breaker: If any discrepancy is caught, LedgerGuard immediately triggers a programmatic circuit-breaker on Dodo Payments rails, freezing payouts before capital leaves the treasury.
- Autonomous Contract Negotiation: An agentic CFO arbiter cross-references legal agreements (MSA terms) and negotiates pushbacks against vendor excuses with strict contractual grounding.
- Self-Healing Settlement: When a vendor provides a corrected invoice, the system autonomously re-verifies the delta, clears the dispute, and unfreezes Dodo rails for instant settlement.
- Immutable Observability: Every audit trace, agent debate span, token metric, and circuit-breaker trigger is recorded live on Neatlogs for real-time compliance.
How We Built It
- Agent Orchestrator (AO): We used Agent Orchestrator with Claude Code and Aider harnesses throughout the entire development cycle to architect our sub-2ms deterministic engine, generate multi-vendor edge cases, and safely refactor our dispute pipeline without breaking production contracts.
- Core Audit Runtime: High-performance Node.js / ES6 backend engineered for line-item differential parsing and zero-hallucination math.
- Liquidity Rail Controls: Integrated with Dodo Payments API to programmatically hold, release, and auto-settle payouts.
- Observability Layer: End-to-end telemetry and execution spans piped via Neatlogs SDK.
- Frontend CFO War Room: Built with React and Tailwind CSS for real-time audit visualization and simulated vendor portals.
Challenges We Ran Into
Managing strict latency and execution order: ensuring the Dodo Payments circuit-breaker triggers synchronously in under 2ms before any automated disbursement occurs, while maintaining asynchronous dual-agent debate loops so audit pipelines never block.
Accomplishments That We're Proud Of
- Achieved 1.46 ms deterministic verification across complex multi-line invoice schemas.
- Successfully integrated Agent Orchestrator to automate testing and iterative code refactoring.
- Verified over $2,300 in protected capital across 5 vendor audits with live immutable traces in Neatlogs.
- Built a complete fail-safe model: deterministic code controls the money, autonomous agents handle vendor diplomacy.
What We Learned
Why enterprise CFOs reject black-box financial LLMs—and how wrapping deterministic circuit-breakers and deep observability around agentic workflows creates enterprise-grade autonomous finance.
