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: ▲10%; Now £7m
Cash at bank: ▼48%; Now £1.4m
Headcount: ▼7%; Now 82
Deferred income: ▼19%; Now £3.6m
Fixed assets: ▲9%; Now £3.2m

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