Intacct Standard Allocations

What factor do you use to allocate utility costs across dimensions? You can't very well allocate all of the phone bill expenses to the Sales Department (even though they likely are the ones most frequently using the phone!). Do you run the General Ledger for a set account (or range of accounts and dimension filters) and then take that aggregate monthly amount and allocate by a percentage? OR do you enter the allocation at the time that you enter your AP bill? Therein lies lies the answer to whether you should use Intacct's Standard Allocations or CLA's Allocation Management. Today's post will cover the topic of Intacct's Allocation setup and use.
