I am runing a construction business. Not ver big, medium size. I am having a hard time managing my funds. There is no unnecessary expenses. I am currently on a project. Purchase order said they will pay on 10th or fifteen of everything. But the client seem to extend time every month. They pay on 20 or 25. This lead to disturbance in my work. I am thinking on getting a bank credit limit sanctioned. For the times when I need to pay for the smooth running of business. I want all of your views on this. Actually, this business was making loss. So I dont have any cash for the purpose of investing. The reason when any payment delays, I have to stop work. Which annoy the client.
