Identify the discrepancy and ask the parties to confirm the actual assignment before relying on either account.
Resolve who directs which work
Preserve the relevant versions and explain the real duties. The final file should describe the employment that will occur, not whichever document appears more favourable. Make a document index that states what each item proves: passport for nationality, degree or licence for the listed qualification, employer letter for duties and temporary need, and contracts for the real work arrangement.
Review the latest signed versions before preparing a packet. Hypothetical example: a hydrology analyst has a letter describing groundwater modelling while an attached statement of work assigns routine invoice reconciliation. The signed scope, supervisor declaration and sample deliverables settle which account is accurate.
Resolve that conflict before presentation; inserting a more attractive description after the fact creates a credibility problem. A packet is stronger when it acknowledges a limited nonprofessional task and shows it is incidental, rather than pretending the task does not exist. Before travel, compare every signed exhibit with the packet index and preserve the controlling version.
A missing signature, stale statement of work or unexplained difference can undermine an otherwise credible professional proposal.
