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: ▲31%; Now £771k
Cash at bank: ▲12%; Now £593k
Headcount: 0%; Now 1
Deferred income: ▲3%; Now £7.9k
Fixed assets: ▲131%; Now £255k

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