The way to handle this is to sit down with them and verify if your suspicians are true.
Review your performance history with them and find out how you have contributed to them.
Before you sit down with them, you need to do your research.
Also research the company they are moving to.
This doesn't happen, generally, unless there is something they are not satisfied about with our service.
Then make an action plan for overcomeing the deficiencies and improving service.
These days, it is about the ABC's of customer service. (above and beyond the call).
Find out from them, if there is anything you can do to increase your service.
Part of your research should be a customer satisfaction survey delivered and analyszed BEFORE you ask for a meeting.
The custgomer satsifaction survey will be a non-threating way for critical issues to surface.
You want two kinds of surveys. One for the employees who receive your services; and the other for the company staff that you work wityh.
(client survey).
In the end, there may be nothing you can do to salvage this client, but you will have gained a lot of information to help you to provide a higher level service to other clients you currently have and future clients as well. You can improve your business model.
