tl;drA command interface, in accounting software, is a way of directing work by describing what needs to happen in plain language, rather than navigating menus, forms, and configuration screens to get there.

Tell it what you need. It handles the transaction, the exception, and the follow-up.

This matters because most ERP interfaces are built around the software's data model, not the way a finance person actually thinks about their work. A command interface flips that: describe the outcome, chase this overdue invoice, match this bill to the PO and flag anything over five percent, and the agent behind it does the work across whatever systems are involved.

Light's version of this is the Light Command Interface (LCI). It runs every agent in Slack, Teams, or the web app, wherever the team already works, with the same roles, approvals, and audit trail as everything else in Light.

This term matters because the work behind it matters more.
