Filed tax returns for the business and, where relevant, the investor; financial statements; bank statements; payroll registers and employment tax filings; lease or premises documents; and updated ownership records. Add anything evidencing the investor's continuing management role. Together these show what the enterprise has done rather than what it once intended to do.
Reconcile the accounts with the earlier file
Retrieve the previous submission and read it beside the current accounts. Where the two disagree, different entity names, a changed shareholding, premises that were never taken, note the discrepancy and prepare an explanation. Accountants and immigration files are usually maintained separately, so the figures may have been presented on different bases. Resolving that beforehand is far easier than answering a request for evidence about it later.
Bring the assumptions behind each line: signed or negotiated lease terms, quotes and orders for equipment, supplier pricing, payroll estimates with roles, insurance quotes, and any letters of intent from prospective customers. Property title and valuation for any asset pledged, the loan agreement and drawdown records, bank statements for every account the money passed through, the purchase agreement and escrow terms, and receipts for equipment and inventory purchased.
