# Definite

> Definite is the financial performance layer. It connects a company's financial stack read-only, continuously finds opportunities to improve cash, margin, and runway, and gives finance the evidence and workflow to capture the value.

Company: Definite (legal entity Ledgix Inc.), a Y Combinator-backed company.

How it works:

- Connects finance systems read-only: ERPs and ledgers, banking and billing, warehouses and BI, documents and spreadsheets.
- Agents run finance workflows: close and reconciliations, controls testing, FP&A and planning, billing and revenue, tax and compliance.
- Deterministic checks decide outcomes; an LLM never decides pass or fail.
- Every number is traced to source evidence, and exceptions go to humans for review.
- Read-only by design: Definite never posts entries, moves money, or writes to source systems.

## Solutions

- [Close & reconciliations](https://usedefinite.com/solutions/reconciliation): Match bank, subledger, and GL balances, investigate breaks, and assemble the supporting evidence.
- [Controls testing](https://usedefinite.com/solutions/controls-testing): Reconcile the test population, execute each test attribute deterministically, and deliver workpapers with their evidence packs.
- [FP&A & planning](https://usedefinite.com/solutions/fpa): Refresh actuals, investigate variances, and trace management reporting back to the underlying drivers.
- [Billing & revenue](https://usedefinite.com/solutions/billing): Find missed billing, mismatched amounts or dates, unapplied cash, and other revenue exceptions.
- [Tax & compliance](https://usedefinite.com/solutions/tax): Reconcile reported values back to finance data, check that expected data is complete, and keep adjustments connected to their supporting evidence.

## Integrations

- [ERP & ledgers](https://usedefinite.com/integrations/erp): Read-only connections to the ERPs and ledgers an organization already uses, mapped into a shared financial context with lineage back to source.
- [Banking & billing](https://usedefinite.com/integrations/banking): Connects invoices, payments, settlements, fees, refunds, and ledger entries, and surfaces missing, duplicated, delayed, or inconsistent activity.
- [Warehouses & BI](https://usedefinite.com/integrations/warehouses): Brings warehouse and BI datasets into the same governed context as ledger balances, connecting reported metrics to underlying financial activity.
- [Documents & spreadsheets](https://usedefinite.com/integrations/documents): Links evidence in Excel, CSV, PDFs, SharePoint, and email to the transactions, balances, and decisions it supports.
