You can provide your own business benchmarks to make sure your business is operating well. Here's a guideline I came up with:
Easy-to-read mission statement for your business Yes No
Use an accounting or bookkeeping system weekly Yes No
Have a lead generation strategy Yes No
Use a marketing plan Yes No
Use a systemized approach to production Yes No
Know monthly costs for running the business Yes No
These areas can be broken down into further sub-categories. But if you answered yes to the general categories then your business is likely operating well and you know if you will be turning an operating profit or not.
If you know your weak areas and simply can't improve, then consider hiring an outside service provider to help at least on an occasional basis.
