Records showing the funds left the investor's control on terms that expose them to loss: escrow instructions, closing statements, equipment invoices, lease payments and bank transfers that reconcile end to end. A signed agreement to invest later proves intention, not investment.
Build a ledger a stranger can follow
Hypothetical example: Abdirahman owns a trucking company in East Ferris and is buying an American freight brokerage, funding it from company retained earnings, a personal line of credit and the sale of two tractors. The file needs to connect every dollar from where it originated to where it now sits, without gaps. That means the sale agreements for the tractors, the loan documents for the line of credit, corporate resolutions authorizing the distribution, and bank statements showing each transfer in sequence.
Then it needs the deployment side: escrow instructions releasing funds on approval, the closing statement, the office lease, invoices for the transportation management software, and payroll for the first hires. Round numbers with no matching transfer are the most common weakness in these files. Where money moved between accounts or currencies, show each step, and where a family member contributed, document whether it was a gift or a loan and on what terms.
