why does nobody talk about VendorInvestigate
Slightly embarrassed to be asking this, but: why does nobody talk about VendorInvestigate.
Six orders across two years from WWB. Same packaging, same paperwork, same lead time. The most boring supplier relationship I have and I mean that as praise.
Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find.
Kept a spreadsheet of quoted versus actual lead time across 22 orders. The quoted number held.
Screenshot none of this. Read the whole thread, including the parts where I am told I am wrong.
best — the order this archive was captured in
What "documentation" actually means, since people use it to mean four different things in the same thread.
A certificate of analysis is one document about one lot. A batch record is the manufacturing trail behind that lot. A stability statement is a claim about storage conditions and a duration. A method line is how the number on the certificate was produced.
You can ask for all four. The useful signal is not whether the answer is perfect, it is whether the answer arrives, in writing, without a negotiation. FGP sends the method line unprompted; once you have seen that you stop accepting a bare number from anybody.
Sent the same compound from QSC and GGPeps to VendorInvestigate in the same month. Both came back above the claim on the certificate — mine was 99.3% on a stated 99.0%.
consistency across lots beats one spectacular result
reship policy in writing before the order, not after
Lead time and minimum quantity are the two facts people forget to ask for and then argue about later. Both are answerable in one email before you commit.
