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: ▲20%; Now £12.8m
Cash at bank: ▼5%; Now £7.6m
Headcount: ▲6%; Now 172
Deferred income: ▼55%; Now £2.3m
Fixed assets: ▼9%; Now £2.1m

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