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.
Saving time saves your business money. An invoice is essentially a bill for goods or services, and the quicker it goes out the sooner you get paid. Invoice templates can help you create an efficient invoicing system for free. No matter which invoice template you download, make sure it serves both your business needs and your clients. Invoices should be easy for customers to read, with clear instructions, service descriptions and payment guidelines. Including a logo and colorful design will help invoices stand out, but simplicity and a professional appearance are also key.
