Availability is the number of days until you can use the money deposited by check as cash. Remember, you only receive a receipt that shows the time and dollar amount on the deposit at the ATM, and you get no receipt at the Night Depositor. Banks charge 3 to 5 cents less for each encoded check. Some banks may require a deposit of an encoded check by 2 p.m., even though the bank is open to 5 p.m. In that case, you lose an entire day's float, even though you did your bit to get the checks cashed.
Many people think it is no big deal to neglect accounts receivable until bills are collectible.
This is bad cash flow policy. It costs you less. Be vigilant and try to get at least periodic payments from slow payers. Ask your bank if they offer Return Item box service. If they do, then use it to redeposit your check and charge back the bank return item free to your customer.
