A job invoice is intended to provide an estimate to clients for how much a project will cost based on parts, labor, and other expenses. A job invoice is not the same as an official quote or contract. If you are a construction contractor or other service provider, you may need to offer clients an initial estimate to give them an idea of the scope of the project. While this is not an official quote, it is good to be realistic about potential costs so that clients understand what they are getting into. Consider providing more than one estimate - one based on the likely cost and another that includes costs for complications that could arise.
Furthermore, some invoice template comes with a table for outlining line item number, description of work provided, hours, rate, amount, subtotal, tax, and total due. Marketing banner on the bottom of the page can be used to advertise products and services
It does not get any easier than this. A simple invoice is ideal for small businesses or individuals who want simplicity and flexibility. Enter a service description, calculate the total, and you’re done. If you don’t need to charge tax, just set the tax rate to zero percent.
You may still be mailing paper invoices or you may be doing all your billing and payments over the internet, either using a website that accepts charge cards or an online payment system that uses email like PayPal. As a freelancer, this affects the part of your invoice that lists how you want to get paid. You may even offer your client a variety of payment options, and all of those should be mentioned on your invoice.
