The question this page answers
What does final site cost tie-out establish in this file, and what additional fact could change the next step? A property project includes drains serving buildings and exterior areas.
Trace the amount to its underlying transaction
Keep the source amount, subsequent credits, payments and proposed adjustments separate. One invoice can be paid in several transfers, and one transfer can cover several invoices. Start with the underlying obligation before treating every payment line as a separate item.
Apply the check to the situation
An industrial property has roof drainage, parking area drains and new exterior stormwater work on a shared plan.
For this check, identify the document that supports final site cost tie-out. Compare it with technical classification review before treating the two records as consistent. A difference may indicate separate events, incomplete history or a correction that has not yet reached every system.
Compare sources before accepting the result
Reconcile the source and destination totals using a written difference bridge. Explain each adjustment with its document reference, relevant entity and period. A zero difference is useful arithmetic evidence, but it does not independently establish tax treatment.
Handle an incomplete or conflicting file
Resolve unidentified amounts before accepting the total. Where a documented estimate is necessary, distinguish the estimate from an original cost and preserve the reviewer's approval and limitations.
| Evidence state | Action for this check |
|---|---|
| Supported and consistent | Record the source version and exactly what it establishes about final site cost tie-out. Leave the tax conclusion to the responsible reviewer. |
| Missing | Request the underlying evidence and assign a follow-up owner. Identify whether the missing item prevents review or only delays implementation. |
| Conflicting | Keep both sources, describe the difference and request an explanation. Do not silently choose the source producing a preferred outcome. |
| Estimated | Explain the reconstruction method, uncertainty and reviewer approval required before using the estimate. |
| Proposed not applicable | Record why this question does not apply and obtain confirmation where the decision depends on that exclusion. |
The focused reviewer handoff
Submit the source reference, the finding about final site cost tie-out, the unresolved difference and the requested decision. If the reviewer approves an action, ask what proves its completion. Continue with drainage drawing identifiers to check the connected part of the file.
