Many large companies worry about investing in a product or service provided by a small company. They fear you don't have the staying power. We are only 10 employees but we have many customer success stories including some very large companies. Looking for unique ideas on how to answer this question in a way that plays more to our benefit.
My answer would be, that all my people are potential supervisors. If I have 1 electrician only, he eventually become a supervisor of 10, if necessary for bigger customer. And I have vast database of potential subcontract roles available, plus internal process for quick appointment, induction and training.
all the best
