I have this same challenge/frustration with intercompany.  I'm new to a smaller organization that uses QBO, and similar to the post above, would love the option for users to vote/elevate requests, suggestions and tools (like MS) that would make using QBO much more efficient, easier, and less likely to have manual entry errors.

I have been given the responsibility to decide if we stay with QBO or look at other solutions to support finance and reporting for our group of small companies.  This intercompany transaction is a big sticking point right now, and it seems crazy to have to use a 3rd party app for this accounting feature.  I was not able to find anything specific that would just to intercompany... so far
