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 £4.7m
Cash at bank: ▼38%; Now £798k
Headcount: ▼5%; Now 56
Deferred income: ▼14%; Now £644k
Fixed assets: ▼12%; Now £1.5m

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