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: ▲30%; Now £11.8m
Cash at bank: ▲24%; Now £703k
Headcount: ▼2%; Now 93
Deferred income: ▼1%; Now £343k
Fixed assets: ▼29%; Now £869k

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