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 £1.7m
Cash at bank: ▼12%; Now £847k
Headcount: ▲7%; Now 73
Deferred income: ▲15%; Now £569k
Fixed assets: ▲1%; Now £390k

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