Regulation CC doesn't prevent you from holding funds pending the posting of an ACH debit (for example, putting a hold on a business's account to ensure the funds are there when the ACH debit comes in to transfer funds to the payroll processor or employee direct deposits). It's very common, for instance, for the debit to an employer's account to post the business day before the direct deposits to employees are credited -- the day before payday.
