BambooInvoice: CodeIgniter Invoicing

Bambooinvoice is free open-source invoicing software intended for small businesses and independent contractors. Our number one priorities are ease of use, user-interface, and beautiful code. Bambooinvoice was built by a designer and programmer, who uses it everyday, not by a large firm who can't remember the names of its customers. It is meant to be sexy, both on top of, and under the hood. Go ahead, kick the tires. View source shows semantic, structured, meaningful XHTML. We use AJAX to keep things peppy and javascript to keep things functional. The entire application degrades gracefully for users without javascript enabled, and complies with WAI priority two.
