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: ▲19%; Now £4.7m
Cash at bank: ▲25%; Now £3.3m
Headcount: ▲4%; Now 93
Deferred income: ▲16%; Now £2.1m
Fixed assets: ▼40%; Now £185k

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