WIP Reporting: How Contractors Prevent Profit Fade

Profit fade is when a job starts at 22% margin and finishes at 8%. WIP reporting is how you catch it — before it's too late to fix.

What WIP actually means

WIP stands for Work In Progress. It's a snapshot of where every open job stands right now:

  • What you bid.
  • What you've spent.
  • What you've billed.
  • What's still left to do.

It sounds boring. It's the most powerful report you own.

The three numbers that matter

Look at any WIP row. Ignore everything except these three:

  1. % Complete. Costs to date ÷ total estimated costs.
  2. Earned revenue. Contract value × % complete.
  3. Over/under billed. Earned revenue minus amount billed.

If earned revenue is bigger than what you billed, you are under-billed. That means you did work you haven't collected on yet.

If it's smaller, you are over-billed. You collected money you haven't earned yet. Watch out — that's fake cash.

How profit fade hides

A job starts at 22% gross margin. Week 4, a subcontractor quotes 15% higher than your bid. You don't catch it. Week 8, materials jump 9%. You don't catch that either. Week 12, you burn 40 extra hours on a rework. By week 16, your 22% margin is 8%.

None of that had to happen. A weekly WIP review catches every one of those hits inside 7 days. You raise the change order. You re-forecast. You protect the margin.

The rule we use with every client

Review WIP every Friday. Every open job. No exceptions.

That one habit is worth more than any new software.
