Indirect — not revenue

Balance-sheet signals

Year-on-year changes in filed balance-sheet items. They can hint at momentum (or investment) but are not revenue or profit and must not be read as such.

Net assets: ▲42%; Now £6m
Cash at bank: ▲512%; Now £7.6m
Headcount: ▼3%; Now 64
Deferred income: ▲120%; Now £1m
Fixed assets: ▼17%; Now £158k

Deferred income is reported together with accruals in this filing (“accruals and deferred income”), so it is an approximate signal only.
