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: ▲25%; Now £10.5m
Cash at bank: ▲59%; Now £6.8m
Headcount: ▼4%; Now 55
Deferred income: ▲304%; Now £350k
Fixed assets: ▲8%; Now £994k

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