Invoices and infographics may seem like two entirely different business materials, but they actually have one key thing in common: they both exist to convey information.

However, while infographics are known for employing colorful designs and data visualizations, invoices are typically pretty straightforward.

Of course, conveying important payment information in a clear and concise way is the name of the game -- but that doesn't mean you can't add a little brand personality to them.
