Bills in. Defensible number out. Then it loops.

What happens to your numbers

1. You enter activity data, not estimates. The kWh from an electricity bill, the litres from a fuel-card summary, the MJ printed on a gas bill. Monthly totals are one entry each.
2. The factor is applied in the open. Each entry is multiplied by the published National Greenhouse Accounts factor for its state and fuel; the factor value, its vintage and its source sit next to the result. Nothing is inferred from what you spent.
3. Emissions are derived, never stored. Your bills are the source of truth. When a factor edition updates, your history recalculates. No stale numbers, no silent re-baselining.
4. The report shows its working. Methodology, assumptions log, factor tables and every entry in the appendices. Built for the person whose job is to check it.

What happens next year

1. Finalising is one action. Sign the year off and the next reporting year opens itself, so there is always somewhere to put the next bill.
2. Reminders are quiet by design. Pick monthly, quarterly or annual check-ins. An email goes to whoever manages the bills, and only when a period closes with data actually missing. No newsletter, no nudge theatre.
3. Year two beats year one. The report gains a year-on-year comparison, and if the two years don't cover the same categories, it says so rather than implying a reduction that's really a scope change.

That loop is the product. A baseline is a project; staying current is a subscription that earns its renewal. Where the year is up to right now.
