What would be the best invoicing software for a mechanic?

Hello, does anyone know what software would be the best for a mechanic to do invoices, a fairly simple one ? Thanks

http://datamasters.net/ I am not sure if it is the best or how simple it is,but you can have a look. There is a free trial download.
