This is my first posting, so thank you for reading!
As a Sourcing Specialist in manufacturing, I see a lot of different requests that buyers submit to suppliers for quotation. They range from machined parts, molding, screws, motors, high volume, low volume, brass, iron, etc. The one thing that all of these buyers have in common though is that they NEED a quote. There are different reasons why buyers outsource but I believe more often then not we have to give them the benefit of the doubt ...that they are not doing it to just exercise their sourcing legs. (Especially when they deal with me....I ask to many questions and it wouldn't be worth the trouble if they weren't serious about obtaining a quote). Here's the point....the undesirable business is still a request that the buyer NEEDS.
So, I encourage any supplier....the next time you see that low volume sand casting or molding and are ready to hit delete, give it a second look. At least look at who the buyer is and ask yourself how hard it would be to get in their preferred vendor program and is this your way to get your foot in the door.
OMG, I could't agree with you more. "I've said over and over Quote the buyer not the part"
Look for a new customer that fits your needs as well as theirs. and then follow through.
