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: ▲15%; Now £2.3m
Cash at bank: ▼5%; Now £1.1m
Headcount: ▼18%; Now 66
Deferred income: ▲44%; Now £2m
Fixed assets: ▲9%; Now £114k

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