The definition is the feature
Every metric here carries its definition — which accounts, over which period, divided by what. That sounds like bookkeeping and it is the thing that decides whether a metric is useful, because the commonest failure of a KPI is not that it is wrong but that two people compute it differently and neither knows.
KPIs
March 2026
| Metric | Definition | Value | Target | State |
|---|---|---|---|---|
| Gross margin | Gross profit / revenue | 64.3% | 65% | Provisional |
| Runway | Cash / 3-month average net burn | 14 mo | 12 mo | Provisional |
| Debtor days | AR / revenue × days | 41 | 30 | Final |
| Revenue per head | Revenue / headcount | — | — | Not connected |
The last row is deliberate. Revenue per head needs a headcount, and there is no payroll source, so it shows nothing at all rather than a number computed from a figure somebody typed once and never updated.
Metrics worth tracking
| Metric | Tells you | Watch for |
|---|---|---|
| Gross margin | Whether the work is profitable before overheads. | A slow decline nobody notices month to month. |
| Runway | How long the cash lasts. | It moves on burn as much as on cash. |
| Debtor days | How fast you are paid. | A single large late invoice distorting the average. |
| Overheads as a share of revenue | Whether growth is being eaten. | It only looks bad in a bad month, which is late. |
| Concentration | Share of revenue from the largest customer. | The number nobody computes until it matters. |
If a metric is something the company is trying to move, it belongs as a goal in Projects with the projects attached. Track it here; steer it there.
What this does not do
Headcount, pipeline and usage metrics are not connected.
Nothing notifies you when a metric crosses a target.
Aggregate figures from the ledger.
Definitions are built from available components.
Questions
Can we track a metric the ledger cannot compute?
Not with a live value. It will show as not connected.
Do targets do anything?
They are shown as context. Nothing enforces them.
Can each department have its own KPIs?
Where the ledger carries the dimension, yes.
