A local review protocol, not a universal benchmark. (https://www.nist.gov/). Treat this as context for planning, not a guarantee about a particular assistant or operating result.
Analysis and operating context
## Question and scope
Which vendor invoices require correction, and what evidence is missing? The scope is the work record and the events the team can observe in a defined window. It does not estimate an industry rate or a legal conclusion.
## Population and unit
Invoices processed in a defined quarter, sampled by vendor and service. The unit is one request, handoff, assistant, or invoice. Linked events are recorded separately so a correction is not counted as an independent success.
## Definitions and measures
Exception rate, missing service evidence, duplicate payments, and correction time. Define the window and evidence standard before the sample begins. A count without its denominator and source is not a measure.
## Where the record fails
Exceptions cluster around recurring services and invoices without a purchase order. A failure needs a reason code, a next owner, and a recheck date. Silence is not a disposition.
## Worked example
A paid invoice without service evidence is an open control gap. The numbers are illustrative. The value is the stage split, which shows whether the delay belongs to intake, review, the destination, or the client.
## Evidence and limits
Public guidance can frame the questions but cannot prove a local result. Samples may exclude untracked work, offline notes, or records that never reached the client system. Record the sample frame, extraction time, and fields that were unavailable.
## Practical use
Change one controlled element at a time: the intake field, the owner, the review cadence, or the stop rule. Recheck the same measure after two cycles.
