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: ▼4%; Now £9.3m
Cash at bank: ▼17%; Now £7.4m
Headcount: ▲2%; Now 67
Deferred income: ▲127%; Now £4.1m
Fixed assets: ▲21%; Now £5.6m

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