One file but separate companys. Set up so that transactions and transfers between companys only need to be entered once.
Example - Bank transfer from Co.1 to Co.2 ........Enter the transfer into one company and it would automatically enter it in the other one.
Or sometimes a deposit might be made into one bank account, but needs to be applied to more than one other company.
Each company could still have it's own separate income, expense, GST, etc. reports and records.
Essentially, combine two or more separate files into one file but with intertransfer capabilities.
Is it possible? Would sure be great if it was!
