Job Cost · Included in Twinn Reports
Job Performance (WIP) for Sage 100 Contractor
The work-in-progress schedule your bank, bonding agent and CPA ask for, without rebuilding it in Excel every month. Every job, its revised contract and estimate, cost to date, percent complete, earned revenue, over or under billing and backlog, as of any date you pick.
It runs in your browser against your live Sage 100 Contractor data, through the Twinn service on your own network, and exports to Excel, PDF or CSV.

Who uses it
- Controllers closing the month
- CFOs and owners preparing for the bank or surety
- Project managers checking their jobs
The questions it answers
- Which jobs are overbilled, and by how much?
- What is our backlog going into next quarter?
- Which jobs are tracking below the margin they were bid at?
- What did the WIP look like at the end of last quarter?
Ask Twinn · Early access
“Show me the WIP schedule as of the end of last month.”
Ask Twinn, the assistant inside Twinn, runs this same report to answer questions in plain English. It tells you which report it ran, with which criteria, as of when, so the answer always matches the report.

How it’s calculated
The same notes Twinn shows beside the report, so anyone reading it knows what the numbers include.
- Cost Estimate is the job budget. Approved prime change orders add their budget (CO Cost) and approved amount (CO Amount). Tick 'Budget and contract already include change orders' if your company posts approved COs into them, otherwise they're counted twice.
- Complete % = Costs to Date / Estimate (capped at 100% unless you allow costs to exceed the estimate). Earned Revenue = Revised Contract x Complete %.
- Over/Under Billed = Billings - Earned Revenue: positive means overbilled (billings in excess of earnings), negative means underbilled.
- Billings exclude void invoices and sales tax. Costs are open job cost records. With an as-of date, costs, billings and approved change orders (by Approved date) are cut off at that date; leave it blank for everything posted.
- Backlog + Billings This Year gives the workbook's 'Backlog + YTD' figure.
