I had a small business before. I think that you can accomplish this by: 1. Buying things for the company only if it's necessary. 2. Teach the employees not to waste supplies, electricity, unnecessary long distance calls. 3. Monitor employees use of their time while they are at work. 4. Send home employees when they are done with their work. Avoid letting them work overtime. I'm sure some will give you some useful inputs. Take care.
