Writing and issuing billing invoices are a basic aspects of running a small business. Billing invoices outline the nature, cost and payment requirements for services rendered by you or your company. The invoice is sent to the customer. For example, a plumber might include the cost of materials, labour and any other expenses in his invoice, which could specify how and when the customer is expected to pay. Billing invoices can be produced on a computer or by using a template on the Internet. Producing a simple billing invoice should take no longer than 10 minutes.
