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: ▲1132%; Now £456k
Cash at bank: ▲12%; Now £25.8k
Headcount: ▲100%; Now 12
Deferred income: —; Now £2k
Fixed assets: ▼17%; Now £10k

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