01 / The premise

Accounting software records numbers. Accounting-Ops records how they got there.

Most financial software is a destination. Accounting-Ops is a living system: transactions arrive, agents reason, rules apply, humans approve, and the ledger preserves the entire story.

System of recordAppend-only journal

System of actionMCP tools + agents

System of trustProvenance + approvals

02 / Ask your books

No report hunting. Just ask.

Your CFO agent answers from current books, shows the underlying math, and takes you directly to the work that needs attention.

Answers, not theater.Live figures, explainable assumptions, and a route back to the underlying records.

03 / Provenance

Every number has a family tree.

Trace a report line through its journal entries, source transactions, and agent decisions. Verify the chain without taking the application’s word for it.

04 / Control

Agents propose. Humans approve.

Automation handles the volume. Materiality rules, confidence thresholds, and approval queues keep judgment where it belongs.

05 / Product tour

One system. The whole financial loop.

Move from source transactions to reconciled books, verified journals, live reporting, and CPA-ready work without stitching together six different products.
