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: ▼24%; Now £1.6m
Cash at bank: ▲44%; Now £2.8m
Headcount: ▼8%; Now 335
Deferred income: ▼14%; Now £1.7m
Fixed assets: ▼9%; Now £2.8m

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