A collection of useful, mostly web based, applications to help you find the tool that can make your work easier. These applications got my attention and I found them interesting enough to share.

The first category contains project management related applications.

The second category contains billing software, invoicing applications free or paid for, useful for small business, startups, freelancers or established companies.

Stay tuned for additional categories in the future, such as analytics, productivity, organization, bug tracking, crm, etc.
