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: ▲9%; Now £3.3m
Cash at bank: ▲5%; Now £726k
Headcount: ▼14%; Now 12
Deferred income: ▲44%; Now £347k
Fixed assets: ▲67%; Now £749k

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