What this file should establish
Separate agreement, payment, transfer, completion and filing dates as relevant. Ask the professional which date controls each decision. Do not use a convenient date simply because the other records are missing.
An illustrative business owner is considering a change in tax classification while the operating model is changing.
A situation to work through
The business has stable sales but the owner has not documented duties or recurring administration costs.
For this situation, start with ownership records. Identify the period and legal owner before combining it with the other records. Keep the original source and explain any adjustments in a separate reconciliation.
Review point
A modeled advantage is a starting question, not evidence that the election is appropriate.
One date is used for several events with different evidence.
Question for the reviewer
Which date facts change the applicable review and what supports them?
Expected handoff
A dated assumption map.
Separate facts supported by documents from estimates and unresolved assumptions. Assign each missing item to a responsible person and a date. Send the reconciliation alongside the source references so the reviewer can trace each conclusion.
