If you have recurring invoices that you send out, you can easily automate this process with autoresponders. Many business owners find that they spend a good portion the day sending out invoices, or trying to collect on unpaid invoices! This can easily eat into the time that you could be spending generating new business. If the amounts invoiced are the same each month, and due on the same day each week or month, you can easily automate the invoicing process with the use of an autoresponder. Many shopping carts that have autoresponders built in work well for this. Others may take a little time to set up, but in the end, they will save a great deal of time overall. Get extra usage out of the automated invoicing process by adding small messages to the invoices that alert these clients to new products or services that you offer. Think about your phone bill y doesnyt your phone company send out additional sales material with each bill? There is no reason you shouldnyt use this same marketing technique with your autoresponder invoices!
