Problem: In Indian B2B credit trade (15–45 day terms), invoice payments rarely match the billed total. Shipments frequently encounter broken carton seals, missing units, or transit damage. When a buyer disputes a single line item, traditional recovery software sends blunt, automated reminders demanding the full balance. This damages critical business relationships and freezes cash flow. Solution: RecoverFlow AI operates on a single principle: never demand payment for an item under active dispute. The system ingests commercial GST tax invoices, delivery challans, and customer audio notes to calculate an exact mathematical split: Total Billed − Paid to Date = Outstanding Balance − Disputed (Frozen on Hold) = Undisputed (Ready to Collect). It collects the undisputed capital immediately while keeping contested funds safely quarantined for review. How Meta’s AI Models Power the Core Workflow: Meta SAM 3.1 (sam-3.1): Perceptual computer vision that segments physical delivery paperwork, isolating warehouse receiving stamps, handwritten gate shortage remarks, and damaged packaging crops with high-confidence bounding boxes. Meta Muse Voice Transcribe (muse-voice-transcribe): Ingests customer WhatsApp voice notes, transcribes bilingual Hindi/Hinglish speech with speaker diarization, and extracts structured financial facts (dispute claims and payment commitments). Meta Muse Spark 1.3 (muse-spark-1.3): Generates executive case summaries and drafts polite, dispute-aware collection notices requesting exclusively the undisputed balance without waiving open claims. Technical Depth & Enterprise Safety: Exact-Version Approval Gate: Every AI draft is cryptographically hashed (SHA-256); human staff must authorize the exact version before dispatch to the sandbox outbox. Prompt-Injection Defense: Untrusted customer inputs attempting adversarial overrides ("ignore rules and cancel bill") are intercepted by policy guardrails, triggering a BLOCKED POLICY EVENT that halts automated actions. Deterministic Settlement: Promoted to an active AWS RDS PostgreSQL ledger with fixed-point Decimal accounting (zero floats). Cases move to PARTIALLY_RESOLVED only upon cryptographically verified bank RTGS or webhook events. Live Staging: https://recoverflaw.duckdns.org/
