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: ▲20%; Now £2.7m
Cash at bank: ▲564%; Now £646k
Headcount: ▲23%; Now 38
Deferred income: ▲97%; Now £348k
Fixed assets: ▼5%; Now £424k

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