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: ▲21%; Now £5.2m
Cash at bank: ▼49%; Now £563k
Headcount: ▼29%; Now 53
Deferred income: ▼50%; Now £165k
Fixed assets: ▼8%; Now £51.1k

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