I'm glad our customer service handles 99% of these requests, but occasionally they reach out to me on our own supplier approval side when it comes to making sure we're passing requirements down the chain.
When sending our forms to our suppliers, we get a number of premade canned responses. The Big'uns will respond with a sometimes 15-page document that explains their policies on social accountability, EMP, Sanitation, HACCP, their supplier approval, etc., etc. I'll read through it and so long as I can find that my company's forms have been addressed, I take their canned response. Lots of times it's because their legal team has gotten involved too, and they don't want some QA admin to put the corporation at risk by agreeing to a form sent by a customer, because if their canned response doesn't meet something I need, I'll respond back with my single form again and ask them to either complete the form or send me a statement on their letterhead.
