First, you should identify what your template needs. At a minimum, your invoice should include certain elements, such as your companys name and address, customers contact information, description of services provided, and the agreed cost for the services you provide. More advanced invoices may include your companys logo, terms of payment, and itemization of goods and services provided.
How can you expect your customers to take your business seriously if your invoices do not appear professional? An invoice is the last impression you give to your customer. Why not close the deal with an invoice template that is professional, free, and easy to use? A professional invoice is critical to your companys credibility, not only so your customers pay you promptly, but also so they call you again for future business.
