# Key Concepts

Ledge is an AI-powered close management platform where a team of agents works alongside finance teams to keep the books current and the close in motion. This guide covers every major feature of the platform, from tracking your close checklist to automating reconciliations, flux analysis, and cash application.

**Agent Studio** — The interface where you create, configure, and inspect AI agents for any close task. Accessible from any task in the checklist.

**Working Paper** — The spreadsheet output generated by an agent, showing all raw data, formulas, intermediate calculations, and final journal entries. Every step is transparent and auditable.

**Agentic Close Checklist** — The full list of close tasks enhanced by AI agents. Tasks connect directly to agents, so the checklist doesn't just track the close — it executes it.

**NetSuite Integration** — Ledge integrates directly with NetSuite to pull GL data, chart of accounts, and aging reports, and to post approved journal entries — all with full audit trail support.

**Slack Integration** — Ledge connects to Slack (and other messaging tools) to send automatic notifications when agents complete tasks, when discrepancies are flagged, or when a team member is tagged in a comment.
