Some providers have a list of all providers that accept their payments. This will allow you to make ACH payments from customer requests without ever having to worry about processing the same thing twice.

If you are considering accepting such payments from customers, you should understand how it works. You will need to make sure you are offering your customers fast and secure ways to pay.

For example, if a customer orders a video online and they want to pay with a credit card, the company should offer a way for them to do so. If they want to pay using a check, the company should send them a memo explaining the process. A brief explanation of the process will help the customer make the correct decision and they can keep their business money safe.
