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: ▼3%; Now £3m
Cash at bank: ▼11%; Now £1.6m
Headcount: ▲20%; Now 77
Deferred income: ▲206%; Now £210k
Fixed assets: ▼35%; Now £308k

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