Bank and merchant-processing statements, payroll or contractor records, the signed lease and utility accounts, supplier invoices, tax filings made so far, and photographs of premises and equipment in use. Together they show a real operating commercial enterprise rather than a plan. Corporate formation papers alone do not carry that point.
Keep the second site's file separate
Identify the premises associated with each invoice and retain expansion records alongside the schedule of conditions. Include ownership and citizenship evidence needed for enterprise nationality, including the applicable at-least-fifty-percent threshold. Identify absent records and assess their importance before submission rather than promising later supplementation.
Sort the records by what each one proves, because a bundle organised by document type hides gaps that a bundle organised by proposition exposes. Existence of a company is proved by formation papers and nothing else follows from them. Trading is proved by merchant-processing and bank activity across consecutive months.
Employment is proved by payroll registers and remittances. Premises are proved by the lease, the utility accounts and dated photographs of equipment in use. Hypothetical example: a file leads with certificates of incorporation and a business plan, and a reviewer reaches the end without seeing a single month of sales; the enterprise may well be real, but nothing in the bundle shows it.
Then list what is missing, say why, and say when it can be produced. Ownership and citizenship evidence supporting enterprise nationality belongs in its own tab, since it answers a question about the company rather than about the trade.
