Intracompany transactions

Hello,

I am very familiar on how to post intercompany transactions but not with intracompany. I am hoping someone can assist me.

My business for privacy is called ABC. ABC has 3 locations, WV, KY, TN.

We utilize the WO module to purchasing, including ROI.

We have a vendor set up as Intraco and when we do work we post it to this vendor but the accounting goes to the expense account and does not help with job costing per site.

What is the best way to job cost per location? Would the transactions go to an A/P- A/R clearing account? 

We recently moved a fixed asset from WV to TN. How do I correctly record this so that I can have the equipment and towing company reflect the location?

Thank you for any insight you can provide.
