Simply Invoices

“Simply Invoices is the easiest way to create invoices from the time you’ve logged in your Basecamp project“.

Simply Invoices seems like a very useful idea for those working with Basecamp and I think their website does a great job of promoting the application. The design is uncluttered, clean with a kick ass logo to compliment the site. The site also boasts some great sifr font goodness. Simply Invoices, Simply stunning.
