Actually only two problems and when I state them if he did one thing different he might of been able to regroup. Procut kept using a line of credit with his bank to finance work. He never saved up a cash to buy materials for new jobs or for a emergency fund to carry him through a dry spell. So once the bank stopped him from getting credit he no longer had money to operate. When the economy when bust along with the housing bubble bursting in 2007. The Fed gov forcede banks to tighten credit. Lines of credit are a type of loan except the banks can demand payment in full at any time and refuse to make any more loans. Procut's bank without warning demanded payment and cut off credit. Procut had his business accounts and personal accounts with the same bank. And this was Procut's biggest problem. His bank took all of Procut's money from his personal accounts and applied those monies to pay off his business loans. Leaving Procut without a dime. No cash no credit and with receivables coming in to slow procut had no money to operate. So you see Procut's biggest mistake was him not keeping his personal money with one bank and his business money at another bank. For even if his business bank stopped his line of credit they could of not taken his money out of his personal bank to pay his business loans.
