Multi-document filling succeeds or fails on two layers. Shared fields such as name, address, date of birth, employee identifiers, or client matter details need to land consistently everywhere they repeat. Then each packet document still has its own exceptions: a checkbox-heavy disclosure, a date format quirk, a role-specific field, or a signature section that belongs later in the workflow.
That is why packet QA should be staged. First confirm the repeated facts stay aligned across the packet. Then inspect the exceptions that only appear once or twice. That review order is faster and more realistic than rereading every document from the top as if each one were unrelated.
