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: ▲0%; Now £7.8m
Cash at bank: ▼19%; Now £2.5m
Headcount: ▼2%; Now 44
Deferred income: ▲31%; Now £14.5k
Fixed assets: ▲5%; Now £3.8m

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