I have a monthly electricity bill (capped amount)that I must oncharge to 5 customers of our business. I currently spend a lot of time calculating how much each customer has used and oncharging them accordingly. I am however considering charging the customers a fixed amount on a monthly basis, such that the amount covers the entire capped amount for these 5 customers. My concerns with doing this are that our business loses a customer and must therefore pay at least the minimum amount of the electricity bill that that business would have been paying. My problems is that I cannot afford to have an employee complete the analysis for this every month and he billing from the electricity company is not very helpful and also the above problem in that we lose a customer who we oncharge. What am I best to do in your opinion? Any ideas?
