Bring the executed reservation agreement with every schedule and amendment, escrow or trust instructions, proof of payment, and supplier correspondence about delivery. Add the wider enterprise file: lease, licences, insurance, vendor contracts and bank statements. Ask the supplier for a written statement of what has been reserved, manufactured or allocated. Correspondence often reveals cancellation rights the signature page never mentions.
Show what the money has already changed
A reviewer reads for consequences: stock allocated to the enterprise, a production slot held, a delivery date fixed, or a penalty the investor now faces. Serial numbers, works orders and shipping schedules do this better than an invoice total. There is no categorical rule that equipment must already be in production use before filing.
Where a record is missing, request it and note the gap rather than treating the file as closed. Consequence is what a reviewer looks for, so collect the records showing that something changed in the world. A works order number, an allocated serial number, a production slot confirmed in the supplier's scheduling system, a shipping booking, an insurance policy naming the enterprise as the insured: each of these exists because the supplier acted.
An invoice total exists because someone typed it. Where a record is held by the supplier rather than the investor, request it in writing and keep the request, so that an unanswered ask is itself documented. Hypothetical example: a machine-parts supply business asks for the allocated stock listing and receives a general availability statement, which is the answer showing the allocation had not been made.
