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: ▲9%; Now £2.6m
Cash at bank: ▼40%; Now £44.3k
Headcount: ▼13%; Now 60
Deferred income: ▼1%; Now £162k
Fixed assets: ▼5%; Now £273k

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