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: ▼14%; Now £338k
Cash at bank: ▲73%; Now £3.9m
Headcount: ▲50%; Now 6
Deferred income: ▼100%; Now £885
Fixed assets: ▼100%; Now £0

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