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: ▼1%; Now £1.1m
Cash at bank: ▼33%; Now £309k
Headcount: ▲24%; Now 255
Deferred income: ▼8%; Now £1.7m
Fixed assets: ▼7%; Now £223k

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