Last accounts published Jan 24 show P&L loss of £2m, negative cash flow (ie out) of £2.3m net and BS shareholders total funds down from £8.3m to £5.3m positive, so could survive for a while but will need serious action to increase sales and cut costs. Next accounts would be due in Jan 2025. I would buy from them but for anything large would collect in person and as a creditor they would be on very tight terms and low limit if I were supplying them.
There is more to looking at public accounts than this, but it is worth doing to get a rough idea and takes a couple of minutes and is free.
