You can use the lockbox function to handle the receipt and processing of incoming payments. This service is offered by banks in the United States.

You send your payments and payment advices to a central bank, usually a postbox, instead of to your bank's office. When the payments have been received, the bank creates a data file from the payment advice data and the customer payment amounts. The checks are credited to your bank account. The file is sent to you at regular intervals so that you can update your books.
