Bring citizenship and passport details for every intended owner, a written description of the business ideas under consideration, and evidence of how your funds were lawfully earned and moved. Personal financial statements, tax records and any existing corporate documents are more useful than a polished pitch deck at this stage.
Build the funds record while the plan is still open
Source-and-path evidence can take time to assemble, and much of the original funding history remains relevant before you select an enterprise. Gather sale agreements, employment or dividend records, transfer confirmations and statements linking each step. If money came from a gift, an inheritance or a loan, collect the underlying documents now, including anything showing what secures a loan.
Much of this work remains useful if you later switch from, say, a service company to a retail concept. Ask for statements covering complete periods rather than screenshots of balances, and keep account numbers consistent across the set so a reader can follow one sum from page to page. Where money passed through a company you own, obtain the corporate records showing the distribution or salary that made it yours, because a transfer from a business account raises the question of who was entitled to the funds.
Note which documents must be requested from an institution rather than downloaded; those carry a lead time, and the lead time belongs in the plan rather than in a later apology.
