"The funds will pay..."

Is an assertion.

Receipts are the evidence the assertion was truthful. GAAP isn't hard for a business to provide. If you committed to using GAAP to account for the disbursements of the DHF funds you received, I could support your proposal. Until you do I cannot, as, for reasons having nothing to do with you, I have committed to withholding support for DHF proposals that do not commit to using GAAP to account for their disbursement of DHF funds.
