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: ▲8%; Now £10.8m
Cash at bank: ▲336%; Now £7.4m
Headcount: ▲21%; Now 63
Deferred income: ▲179%; Now £6.4m
Fixed assets: ▼15%; Now £184k

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