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: ▲28%; Now £6.2m
Cash at bank: ▼9%; Now £1.8m
Headcount: ▲11%; Now 80
Deferred income: ▼38%; Now £372k
Fixed assets: ▲1%; Now £271k

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