Ballpark
The Ballpark interface.
If you’re looking for a web app to create and track estimates and invoices, the recently launched Ballpark looks promising. Similar to web apps like Basecamp, Ballpark allows you interact with your clients via the web app, rather than simply just using email.
Like everything I’ve seen from the crew at metalab, Ballpark is visually stunning. If the usability is as good as the visual interface, apps such as Harvest and Billings have some new competition.
