There are some downsides to getting paid daily. One of the major considerations is refunds, returns, or chargebacks. The affiliate program or network will typically have some kind of lag period between the sale and paying the commission because they need to account for refunds. When a sale is canceled, the network will need to reverse the commission for these which means if you have already been paid, you will essentially owe the affiliate program. It is extremely important to check the terms and conditions of the program with regard to daily payments.
