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: ▼40%; Now £8.1m
Cash at bank: ▼16%; Now £7.2m
Headcount: ▼7%; Now 26
Deferred income: ▼29%; Now £675k
Fixed assets: ▲13%; Now £4.5m

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