HI Debora, We re a cost plus construction company, and switched from Quickbooks to Master Builder (now Sage) twenty years ago. We struggled at first, but worked with Kathryn (at Sage) to work out a process that works for us.  We had previously provided to the client both an AIA  Application and a detailed listing of all costs. To accomplish this in Sage, we create a 3-7 Progress Billing Invoice, which breaks down all billable expenses to the cost code level and compares to the job's contract; then we create a 3-10  T&M Invoice which individually lists expenses being billed on the Progress Invoice.  Once you post the T&M invoice, those costs become "billed" -- this helps to not bill any cost twice.  We provide both the AIA type - Progress invoice and the T&M invoice (which we renamed "Invoice Detail" to our client each billing period.)   This has worked for us -- and acts as a checks-and-balances routine for our A/R team as the two reports should match.  Once issued, be sure to delete the T&M invoice so that you don't have two invoices in your system.  Hope this helps somewhat.

Thats a lot of work for a cost plus job (when there is no hidden markup).  You can just use the T&M Summary to show billed to date.

Isn't time consuming to create a Progress Invoice. All of our projects are large scale and referred through an AIA, and most AIA's (at least here on the east coast) require billing to be provided using an AIA billing format. This allows monthly billing to be routed through the architect for approval and signature if required. It is also more professional vs just providing a summary report. We have modified the Progress Invoice cover sheet to include job-specific information also (deposit on account or realized variance).
