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: ▼13%; Now £17m
Cash at bank: ▲1%; Now £9.8m
Headcount: ▼10%; Now 132
Deferred income: ▼51%; Now £453k
Fixed assets: ▼18%; Now £2.5m

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