Interesting approach. Did you ever try to include other factors into the model ? Such as : * cost of sales (and crm, and billing) * cost of infra * taxes (on income and profits) * taxes (on salary) * cost per employee (office, PC, software licenses) * cost of loans needed for the investment Would be curious to see how big the ratio remains.
