Answer:
When Nicky writes a check, made out to Franco.
Step-by-step explanation:
Since Franco, a consultant, uses the cash method of accounting for his business, then Franco should recognize income when he receives payment for the work he has done as opposed to accrual basis which is when the income is earned.
Cash basis method of recognition would align most likely to when Franco receives his check from Nicky because that is when payment being received, not when the invoice is sent, which aligns more with accrual basis of income recognition.
