Having cash available can be extremely valuable.
Knowing you can withstand a bad month (or even year) can be the difference between a somewhat stressful year and a complete failure.
Knowing you can capitalize on an opportunity when it arises has great value. When your competitors are failing, if you have the resources to make acquisitions when others are desperate can you put you in a position of power.
Knowing you can negotiate by paying cash (asking for a cash discount for paying cash can get you a savings of 2-3% if you can get to the right person) has great value.
While some people might see having a cash safety net as unnecessary others realize the tremendous value it can provide.
Have a great day!
