Test the plan at several exchange rates, at the supplier's new payment schedule, and at a launch date one quarter later than hoped. Show remaining cash at each point. Also separate legal fees, translations and government charges from the investment itself, and verify official fees when each step arrives rather than relying on older figures.
Show the worst case, then show it still works
A plan that only survives the optimistic scenario invites doubt about marginality. Present a conservative case with slower sales, a weaker Canadian dollar and the full inventory commitment, and identify the reserve that carries the business through it. If the reserve is a loan, state what secures it.
Nobody can promise a return, so the useful test is whether the enterprise remains viable when assumptions disappoint. Separate a stress test from a forecast, because they answer different questions and are routinely merged into one hopeful document. A forecast states what the investor expects; a stress test states what survives once the expectation fails.
Present both and label which is which. The reserve named in the conservative case deserves evidence of its own, whether a statement showing the balance, a committed facility with its terms attached, or a lender's agreement setting out what secures the loan. An unevidenced reserve is carrying the entire conservative case, and a reviewer who cannot see it will read the optimistic scenario as the only one on offer.
