Here is a short list of some of the free tools that I use to make life a bit easier.

File Storage and Sync

Dropbox: The free Dropbox account comes with 2GB of space that you can use for as long as you like.  Need more than 2GB of space? Dropbox offers Pro plans up to 100GB to meet all your sync and sharing needs.

Amazon Cloud Drive: Upload your music, photos, videos, and documents from your computer to your Amazon Cloud Drive. You’ll never lose your files from a hard drive crash or a lost or stolen laptop. Download and preview your files with any web-connected computer.

Invoicing

Invoice Machine: The Invoice Machine takes a new clever approach to online invoicing. It’s beautiful and simple-to-use interface makes producing professional looking invoices a very pleasant experience. The Invoice Machine is ideal for freelancers and businesses who want an easy way to manage, create and send their invoices. It’s great for anyone who has a service or product to sell.

FreshBooks: When you think of accounting, is it unorganized spreadsheets and a shoebox of receipts? Or a bloated accounting package? As a professional, invoicing is 90% of your accounting. FreshBooks also simplifies the rest with expense tracking and straightforward reporting designed just for you.

Social Media Management

Hootsuite: Monitor and post to multiple social networks, including Facebook and Twitter using the HootSuite dashboard. Create custom reports from over 30 individual report modules to share with clients and colleagues. Track brand sentiment, follower growth, plus incorporate Facebook Insights and Google analytics all without leaving the dashboard.
