A general ledger built for the agentic era: entries post themselves from the systems that created them, every balance traces to its source, and the books stay close-ready every day, not one painful week per quarter.
An invoice is issued in another system; its journal entry writes itself into the ledger, sourced and linked.
Month-end: the close checklist ticks itself down: reconciled, traced, done.
The trial balance lands. One line: "Accounting that closes itself."
The problem, then the fix
BEFORE
Entries typed from other systems, spreadsheets reconciling spreadsheets, and a quarter-end scramble.
WITH OTALLY
Source systems post directly; double-entry integrity and audit trails are enforced by the kernel, not by discipline.
THE RESULT
The close becomes a review, not a rebuild, and every number can defend itself.
The kernel, in one glance
Where it stands
The double-entry kernel is built and in active development; invoicing and Ontario tax are landing next. Built by the same studio that runs live operations and payroll systems in production today.
