Budget beyond the freight quote: crating, insurance, customs brokerage, duties or tariffs where they apply, compliance modifications, electrical conversion, installation, calibration and downtime while machines are in transit. Add appraisal and translation fees. Government charges and professional fees are separate again, and current official amounts should be confirmed at the time of each step.
Separate what buys capacity from what buys paperwork
Some spending increases the enterprise's productive capacity; other spending simply gets a case ready. Both are real, but they are argued differently, so track them apart from the first invoice. Ask any adviser for an itemized scope covering valuation review, transfer documentation, the enterprise plan and dependent assistance, and ask what happens if a review finds the committed capital too thin. No fee, however large, buys an approval or a return on the investment.
For an existing mechanical contractor the total cost includes the asset price, licensing and insurance transfers, vehicle and equipment needs, and the operating reserve required to carry payroll and materials until receivables turn over. Plans understate this in predictable ways: leasehold improvements, licences and permits, insurance, deposits, initial inventory, the first months of payroll before revenue arrives, and professional fees for incorporation and closing.
