Assess whether the unresolved payment is material to the claimed investment and what reliable evidence already exists. A self-imposed submission date should not lead to presenting uncertain facts as settled. Ask the reviewer what can be accurately supported now and which explanation or correction should be obtained first.
Set a documentary milestone for the disputed payment
Track the supplier’s response, the accountant’s reconciliation and any contract review needed. If the amount changes, update substantiality and operating-budget assumptions before finalizing the evidence. Keep travel and U.S.
work plans tied to actual authorization, not to the date a supplier promises to answer. No invoice correction guarantees approval or a processing date. Deadlines set by the applicant tend to outrun the suppliers who must answer them.
The practical fix is a milestone rather than a date: nothing is finalized until the supplier’s written explanation and the accountant’s reconciliation of that one payment are both in the file. Send the request with a specific question and a copy of the invoice attached, because a vague inquiry to an accounts department returns a vague answer weeks later. The legal frame does not move for a calendar: the capital must be irrevocably committed and at risk, and an amount still under discussion has not yet been shown to be either.
Hypothetical example: a treasury reporting implementation invoice remains unexplained in April, and the schedule is finalized in June once the vendor’s letter and the reconciliation have both arrived.
