The problem: certificates that can't show their workings

When a customer questions a CoA, the answer is spread across specs, batch records and signatures. Pulling them together takes time the customer is waiting on.

A customer asks why one value on a certificate looks off. Answering means finding the spec version, the tested batch, who signed it and who issued the certificate, often across several systems.

Why it matters

How quickly you can answer a customer question affects how much they trust your certificates. A certificate linked to its spec, batch and signatures has its evidence one click away.

The certificate's own event log shows who approved and issued it, so the answer is complete without a manual investigation.

The event log shows who approved the certificate, who moved it to issued, and when. So, the answer is clear. Gloss 88.6 inside the 85 to 100 range from a signed batch. Every certificate traced to its data.
