# 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. This is the expanded companion to https://usedefinite.com/llms.txt with fuller per-page descriptions. Company: Definite (legal entity Ledgix Inc.), a Y Combinator-backed company.

Connect the financial stack read-only: ERPs and ledgers, banking and billing systems, warehouses and BI, and documents and spreadsheets. 2. Agents run finance workflows across those systems: close and reconciliations, controls testing, FP&A and planning, billing and revenue, and tax and compliance. 3. Deterministic checks decide outcomes. An LLM never decides pass or fail; agents do the mapping, investigation, and assembly, and versioned deterministic checks issue the verdict. 4. Every number is traced to source evidence, so results can be reviewed and reproduced. 5. Exceptions go to humans for review. Approvals and overrides stay attached to the result. Read-only by design: Definite never posts entries, moves money, or writes to source systems. Posting and filing remain with the customer. ## Pages ### Home URL: https://usedefinite.com/ Overview of Definite, the financial performance layer. Definite connects the financial stack, continuously finds opportunities to improve cash, margin, and runway, and gives finance the evidence and workflow to capture the value. Summarizes the workflows Definite runs (close and reconciliations, controls testing, FP&A and planning, billing and revenue, tax and compliance) and the systems it connects to. ## Solutions ### Close & reconciliations URL: https://usedefinite.com/solutions/reconciliation Definite matches balances across bank statements, subledgers, and GL balances, investigates breaks, and assembles the supporting evidence. Coverage includes account reconciliation and close (bank statements, subledgers, GL balances, and approval evidence matched and explained), project and supplier cost (what procurement approved versus what project accounting posted: missing, duplicate, or misallocated), and payments and money movement (obligations traced through funding, settlement, returns, fees, and accounting entries). Corrections are routed to finance with the evidence attached; Definite itself never posts. ### Controls testing URL: https://usedefinite.com/solutions/controls-testing Definite reconciles the test population, executes each test attribute deterministically, routes incomplete evidence to reviewers, and delivers the workpaper with its evidence pack. Missing or disputed evidence is surfaced rather than passed. ### FP&A & planning URL: https://usedefinite.com/solutions/fpa Definite refreshes actuals, investigates variances, and prepares management reporting from one governed context, with changes traced back to the underlying drivers in the source systems. ### Billing & revenue URL: https://usedefinite.com/solutions/billing Definite connects the commercial chain to identify missed billing (a contract term with no invoice raised), mismatched amounts or dates (an invoice that disagrees with the booked deal), unapplied cash (a payment received against no open item), and other revenue exceptions. Each exception is investigated with evidence attached and made ready for human review. ### Tax & compliance URL: https://usedefinite.com/solutions/tax Definite reconciles reported values back to finance data, checks that expected data is complete, and keeps adjustments connected to their supporting evidence. ## Integrations ### ERP & ledgers URL: https://usedefinite.com/integrations/erp Definite connects read-only to the ERPs and ledgers an organization already uses and maps them into a shared financial context with lineage back to the source. It does not replace the ERP or become the system of record. ### Banking & billing URL: https://usedefinite.com/integrations/banking Definite connects invoices, payments, settlements, fees, refunds, and ledger entries, and surfaces missing, duplicated, delayed, or inconsistent activity across banking and billing systems. ### Warehouses & BI URL: https://usedefinite.com/integrations/warehouses Definite brings warehouse and BI datasets into the same governed context as ledger balances, connecting reported metrics back to the underlying financial activity. ### Documents & spreadsheets URL: https://usedefinite.com/integrations/documents Definite links evidence in Excel, CSV, PDFs, SharePoint, and email to the transactions, balances, procedures, and decisions it supports, so document-based evidence participates in the same traced workflows as system data. ## Company ### About URL: https://usedefinite.com/about What Definite is and the principles behind it: context before agents (systems are compiled into canonical financial concepts, mappings, and lineage before any agent runs), labor separated from truth (agents map, investigate, explain, and assemble, while deterministic checks issue the verdict), uncertainty as a real state (when evidence is missing or disputed the answer is CANNOT_VERIFY, never a false pass), and evidence captured during the work rather than reconstructed later. ### Security URL: https://usedefinite.com/security Definite's security posture: read-only ingestion scoped to the sources a workflow needs, tenant boundaries that keep customer data and mappings within their own tenant scope, bounded agents that operate inside explicit source, tool, and budget limits, versioned mappings with provenance, tamper-evident results (hashes, signed results, and append-only events), and human authority over approvals, overrides, posting, and filing. ### Contact URL: https://usedefinite.com/contact "Bring us one workflow." Prospects describe a process that is costly to execute and hard to prove; Definite runs it against a period they already closed and shows the result.
