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: ▼37%; Now £2.3m
Cash at bank: ▲614%; Now £792k
Headcount: ▲14%; Now 231
Deferred income: ▲76%; Now £279k
Fixed assets: ▲32%; Now £133k

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