Create a codebook with observable tests for eligible, achieved, open, returned, excluded, and indeterminate. For this topic, the exception map should explicitly cover rolling reserves, fixed reserves, chargebacks, refunds, fees, currency conversion, negative settlements, account migrations, release delays, and contract changes. Each state needs required evidence, a decision owner, and a rule for conflicting records. --Done-- is not usable evidence unless the supporting record, decision, and timestamp can be traced.
Train preparers on ordinary, missing-source, duplicate, late, reopened, and judgment-dependent examples. Then have a second reviewer independently classify a sample without seeing the first result. Publish the sample size, disagreement count, initial codes, and resolution method. Repeated disagreement is evidence that the rule, system field, or evidence requirement needs repair; it is not a reason to erase the conflicting observations.
The bookkeeper may collect records and apply approved rules. The controller, treasury owner, or ecommerce finance owner resolves matters outside those rules. Preparers should not infer approval from a prior-period email, copy last month's treatment without current support, or change a classification to meet a target. Those shortcuts create tidy numbers while weakening the decision the study is meant to support.
