We had an issue with a supplier last week, one of my staff came in very worried about a huge invoice which had been sent in from an outside lab. After calling the supplier cheeky bastards who were about to find out what they could do with their invoice etc, I told the staff member I would sort it out and they left feeling much better. I then wrote the following email:
"Regarding your new policy of billing us for additional elements, not requested on the initial order.
While we appreciate your flexibility and customer service, I am aware that we have been making these requests more regularly and I understand that it must be very disruptive to your workflow. I apologize for the disruption and we will take steps to improve the accuracy of ordering process.
Having said that when we were informed of the policy change we were not informed that we would be charged 1200RMB which I think is the equivalent of a new single element scan. If we had been aware at the time we would have queried it. Please can you reconsider the rate, I think that a more reasonable fee would be 100RMB per element, unless the sample actually has to be re-run."
They agreed and I thanked them in another email.
Communication is about getting what you want, business is about building and maintaining relationships. I showed my colleague I was as concerned as they, maybe even more so, and I got the supplier on side. Being nice didn't cost me anything and probably saved my company a few hundred quid compared to sending something Teutonic, or worse a shitogram.
The only thing I regret is not suggesting an even lower rate,
