An easy trap to fall in is 'the right way is the only way' syndrome. Classifying every business financial condition (like the justice system classifies decisions) is NOT guerrilla accounting. Outside of the box could be totally in space. Some businesses in Middle and South America for example, are operated in such a way that reorganization is impossible, the right hand does not know from the left, and getting in to their accounting
picture for a US trained administrator is an education you may not want.
After years of training to use the balance sheet as a guide to a businesses viability,(compartmentalizing) also for credit and tax purposes, and then see one operate totally in the dark for 25 years seems irrational, but it happens. Prudent banking practices seem to be 'out the window' in these cases, but we negotiated an unsecure line for an owner like this, kept him out of court. ( By the way, that business moved from Nicaragua to Texas. They tried to file there and could not. The line was set up and they are in good shape now.)
If we had put this deal 'in a box', he would have been a dead duck, but GUERRILLA TACTICS along with the owner and his family being so NICE and HUMBLE made this deal fly. Sometimes being 'nice' is the best collateral, also there is no discounting blind luck.
