Treat them separately. Business expenditure such as lease payments, deposits, fit-out, and inventory is part of the enterprise's cost. Immigration-preparation fees are personal expenses of the application. Some business-related professional costs may be treated differently, so ask counsel to review the actual expense rather than assuming a single rule covers all fees.
Budget for the lease term, not the launch
A lease commits the business to payments over months or years, so the budget should show how those instalments will be met while revenue builds. A hypothetical planner might hold several months of payments in the operating account as a working reserve; that is a planning choice, not a legal requirement. Include government charges in the budget using verified current figures or clearly labelled provisional estimates, and record every invoice against a category so the investment schedule stays coherent.
Investment means funds committed to the enterprise and exposed to loss if it fails. The investment must be substantial in relation to the total cost of purchasing an established enterprise or creating a new one. Keep three budgets separate: the investment itself, which must be at risk in the business; working capital the buyer holds in reserve, which is not counted until committed; and the consular application fee, professional fees and translation costs, which are never part of the investment.
