Remove hidden data and uncontrolled copies
Bid files can expose comments, tracked changes, hidden sheets, previous customer names, internal margins and temporary exports. Clean a controlled review copy without overwriting the accountable source.
Before external partner review, the proposal lead duplicates the approved package, inspects document properties and hidden spreadsheet content, removes unrelated pricing assumptions and compares totals against the source.
Run the control in five steps
- 01Create a controlled staging copy from approved sources.
- 02Inspect comments, tracked changes, metadata and hidden content.
- 03Review formulas, external links, embedded objects and macros.
- 04Remove unrelated customer, employee and margin information.
- 05Compare totals, page counts and hashes before approval.
Preserve the decision trail
Keep source, staged version, removed elements, link review, calculation check, hash, reviewer and approval.
Stop and investigate when
- A hidden pricing tab names another customer.
- The package links to a personal drive.
- Totals change without a recorded explanation.
State what this does not prove
Does not replace provider permissions, guaranteed backup, password recovery or enterprise identity management. Solicitation rules, portal identity, contractual safeguards and authorized review remain separate.
