When a job is active (not invoiced) it will use the estimated cost, which is the later date on the Buying tab or Vendor tab. When the job is invoiced, it will show the actual cost from the FIFO purchase order used.
Following is an outline of how the general ledger accounts are affected at each stage of the job process.
To view the accounting entries, go to Accounts > Transaction Journal and select Document #. Choose Invoice and enter the invoice number.
The Transaction journal will then show where income and cost of goods sold impacts the general ledger.
