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: ▲23%; Now £3.8m
Cash at bank: ▲9253%; Now £338k
Headcount: ▲5%; Now 66
Deferred income: ▼90%; Now £73.1k
Fixed assets: ▲39%; Now £111k

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