Cost planning
Build a complete uses-of-funds schedule
A supplier proposal is the beginning of the budget, not necessarily the final number. Capture design and layout services, site verification, engineering, permits, demolition, disposal, wall components, glazing, doors, hardware, freight, delivery constraints, lifts, installation labor, patching, painting, data cabling, electrical work, HVAC changes, sprinklers, alarms, signage, cleaning, and a measured contingency. Keep allowances visible rather than burying them in one figure.
Then map the budget to dates. Record the deposit date, drawing approval, material release, expected shipment, installation mobilization, progress payments, inspection, punch-list completion, and final payment. This cash-flow calendar helps determine whether the business needs one lump sum, staged access to capital, or a revolving source for variable costs.
Practical checkpoint: Ask vendors which charges are refundable, which items are custom and noncancelable, and how long quoted pricing remains valid. Those terms can matter as much as the headline project total.
