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: ▲45%; Now £4.2m
Cash at bank: ▲22%; Now £4.6m
Headcount: ▼3%; Now 28
Deferred income: ▲18%; Now £3.6m
Fixed assets: ▲1%; Now £2.3m

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