I lease nothing and have NO outstanding obligations in my business... I pay cash for all materials and supplies and give no more than net 30 terms to any customer. I have run the business this way from day one! I have done business with companies worth BILLIONS of dollars. Why should I be financing companies worth several thousand times more than mine? It makes no sense (and no cents).
If all work were to dry up tomorrow I could turn out the lights and go look for more work with NO ill effects to the business.
