Job Setup - Phase and Cost Types

[HappyCamper436]

Beginning to configure PeachTree Complete. Would like some information on Phases and Cost Types. We are converting from another system and will maintain the Time and Expense Reporting for Timecards and Expense accounts as the Time/Expense reporting system is a stand alone electronic tranmittal of time/expenses from remote locations. As the time reporting uses Job # and Phases, we will need to include these in PT. However I am not quite sure of the Cost Type option. For Expense reporting we have an "Expense Type" to signify the Expense account GL code. Currently the same phases are used for both Time and Expenses. I guess there is no way to use the same PT Phase "code" for an entry that uses a Cost Code and one that does not. How will we be able to bridge the Time/Expense reporting when the current system uses the same Phase for both Time and Exspense reporting and it seems the PT must have 2 separate task - one for Labor and one for Expense reporting.
BTW I have just purchased PT for Dummies and have not found a solution yet.
Thanks in advance for any assistance.
