The OfficeBooks Help Blog is our way of delivering up to date user support documents in a timely fashion.
There's a structured set of links to individual blog posts available after you login to OfficeBooks, but we update the blog (almost) everytime we get a new question from a user - so chances are pretty good the answer to your question is on the help blog.
We plan to release more walk-through tours to guide you through certain processes like creating invoices, bills of material and workflows.
If you get lost or confused about how to do something - just drop us a line. We really like to help.
