# How Tally works

Financial operations teams manage billing across a huge variety of shipments, clients, and service types — each with their own contracts, rate structures, and documentation requirements. Generating accurate invoices at scale, and getting them out the door quickly, is one of the most operationally demanding parts of the business.

Tally ingests your unstructured commercial and operational data — contracts, rate cards, quotes, SOPs, emails, TMS and WMS feeds — and uses it to generate the perfect invoice. It helps finance teams accelerate and automate the most painful parts of the job: hunting for backup documents, checking for completeness, generating line items, submitting invoices, tracking aging, and managing cash application and remittance.

#### **How it works**

The engine behind Tally is the Logistics Context Graph (LCG) — a living knowledge graph that models your freight operation as a connected network of shipments, carriers, invoices, contacts, and rates.

The LCG resolves fragmented data automatically. It recognizes that "Ref #123" on an invoice and "Container 123" in an email thread refer to the same shipment — and links them without manual mapping, regardless of how your carriers or partners format their data.

#### What You Can Build

The LCG is designed as an intelligence layer for your applications:

* Agentic assistants: Natural language Q\&A over your entire logistics operation
* Operational/Financial dashboards: Real-time financial insights on a shipment level across all data sources
* Exception management: Detect anomalies by traversing relationships (e.g., a shipment missing expected events)
* Cost analytics: Aggregate charges across shipments, lanes, carriers, and time periods
* Compliance & audit: Full provenance trail from any data point back to its source document
* Workflow automation: Trigger actions based on graph state changes (new shipment, milestone reached, charge discrepancy)
