I've now retired from the small business consultancy that I ran for fifteen years before retiring at the end of 2011
Small businesses—those in the range of $6-12 million in annual revenues—often experience a stall in revenue and profit growth around this level. The problem is that their initial 'Mom and Pop store' management model, while great at first, quickly become inefficient and ineffective. Companies like this need to develop a slightly more formal 'medium-sized' business model to allow smooth growth through the next stage.
That was where I used to help but alas, no longer!
