We have a commercial customer who has started asking us for PPAPs via email requests. I'm hesitant to just start providing PPAPs because we are not required to do so in the customer's contract / PO. This applies to new products, and for revisions to existing products. My plant manager is getting annoyed with me because I keep asking why the customer suddenly need PPAPs. My company's previous owners refused to provide PPAPs, but the customer kept buying product from them regardless. I feel like the customer's current requests are unreasonable, considering they've been doing business fine without PPAPs. All that said, I'm probably fighting a loosing battle here, and I know that I probably need to just shut up and start producing PPAPs. On the other hand, shouldn't we at least be charging the custoner for these reports? What would be a good rate to charge?
