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: ▼9%; Now £10.5m
Cash at bank: ▲17%; Now £5.7m
Headcount: ▼9%; Now 52
Deferred income: ▼46%; Now £179k
Fixed assets: ▼37%; Now £3.8m

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