You can change the pdf theme for the Sales Invoice by going to Settings -> Sales/Purchases -> Document Templates

The following PDF themes are available:

Business

BUSINESS is a default theme. Conservative and austere, it says, "We’re a serious company". This theme can be used for any business activity.

City

 

Classic

CLASSIC is a traditional theme. It has everything you need and nothing you don’t: a cloud of digits and some text on a scrap of paper. CLASSIC is the choice of professional salesmen.

 

Lime

 

Live

LIVE is all about colors and emotions. You don’t like boring bills and invoices? Add some color and cheer up your customers. This theme is perfect for service providers.

 

Live+

LIVE+ is the art nouveau of colors. Your bills and invoices all look the same but you want something new? Then this theme is for you! It’s very stylish and modern and can be used for any business activity.

 

Mint

 

Orange

ORANGE is like a ripe juicy orange. This theme is your orange mood and your billing and invoicing creativity, and it too can be used for any business activity.
