Excellent list of resources, PostRank and AddThis look good, but he left out SproutSocial, a competitor of HootSuite.

Tools like Hootsuite or Buffer help schedule posts consistently.

Here are a few I recommend:Accounting: Xero- great software the connects to many other systemsProject management: Workflow Max- there are a lot more, just a suggestionProperty Management: PocketRent reconciles rent and does reporting as wellMarketing: Really depends on your strategy but Hootsuite is great to automate general social media, RadPadDocumentation: Google Drive or Dropbox.

Some great tools that allow you to manage and simultaneously update your profiles from one tool I include hoot suite and tweetdeck, both are free.

hootsuite

Ive been researching ones like Hootsuite, Buffer, Freinds+me, etc. and they all provide different things but none seem to be the right fit.We have ~50 properties each with its own Facebook, Yelp, and Google+ page.
