Financial reporting system / Est. Apr 2024

Every decision
leaves a trace
in the ledger.

Bill is 26. He graduated in April 2024 with 1,000 euro in his pocket. Six weeks later he started his first job. Since then, every financial decision he makes is recorded here, in accounting terms.


Budget variance

The energy bill was 42 over budget. Only 17 was Bill's to fix.

In August the energy bill came in at 132 euro against a budget of 90. The easy reading is one number, 42 over, and one response: spend less. A controller does the opposite and splits it before reacting.

Twenty-five of the overrun is price variance: the market rate rose, not Bill's decision, and it is structural, so the monthly baseline drops permanently from 185 to 160. Seventeen is consumption variance: he used more than planned, a one-off he can actually fix. React to the total and you mismanage both.

The system

Object 01 / EP

Each episode is a ledger entry

One decision by Bill. One accounting concept. Numbers that update the system state. Every EP is an atomic record: self-contained, traceable, part of the sequence.

28 entries recorded / FY2024-FY2026

Object 02 / FY

Each fiscal year is a season

FY2024 opened the books with 1,000 euro. FY2025 tested going concern. FY2026 is the restatement: two years of decisions, one open ledger. Each FY page is a financial statement, not a blog archive.

The BillBoard is his dashboard

Every EP includes an interactive financial dashboard: Bill's ledger, his four vitals, and the accounting insight behind the decision. It is not a widget. It is a management dashboard abstraction of his financial position.

The entity

Bill is not a case study.
He is a persistent entity
in an open ledger.

He started with 1,000 euro in April 2024. Every number since then is the result of a specific decision, recorded in a specific episode. His net worth is derived, never assumed.
