Implement key account activities
A key account will stay with you forever if they understand the importance of what you do and that you'll continue to do it better than any competitor. I want to share ideas with you on the kinds of activities you might consider as you work with your key accounts. First of all, look for ways to integrate your business and their business as much as possible. What parts of the business can be merged or joined together to create efficiencies? For example, are there information systems or websites that can be shared? Are there supply chain resources like warehouses or distributors that you can share? Would it make sense for your company to have some of your employees located at the key account's sites? Because these initiatives help keep your company front and center in the mind of the customer.
Second, create an annual event calendar that involves your key account. For example, would it make sense for their employees to get tours of your facilities so they better understand what you do? How about if you and your key accounts.
