To summarize, cash is always king but definitely in restricted capital environments. Money is still available but it takes longer and requires more creativity and perseverance to access it. Therefore, plan your cash needs and budget your cash resources as much as possible. Know your daily spend rate and be able to quickly determine how much cash you have on hand at any given time. Know your expected operating cash flows and the timing of those cash flows. If you do not, you are headed for trouble.
Or you may already be troubled - stressed out, continuously seeking money from somewhere, continually trying to increase revenue even though you may lose money with each sale. Stop. Determine your cash outflows and inflows on a per project basis, and make decisions based on that information. In this market, you may have to jettison slow-paying, high complaint customers. When cash is king, these customers drag down your bottom line.
