WIP Report Explained for Law Firms



WIP stands for Work In Progress—and a WIP Report shows all billable work your firm has done but hasn’t yet invoiced. It’s one of the most important financial tools for managing law firm cash flow and revenue.


What a WIP Report Includes:

  • Client or Matter Name

  • Timekeeper (lawyer/staff responsible)

  • Date of work done

  • Billable hours recorded

  • Hourly rate or fixed fee value

  • Total unbilled amount per matter

  • Age of the work (how long since the work was done)




🎯 Why It’s Crucial for Law Firm Cash Flow:

  1. Forecasts Future Income – WIP is potential revenue.

  2. Highlights Billing Delays – Aged WIP = delayed invoicing = delayed cash.

  3. Improves Accountability – Identifies who is logging time, and who isn’t.

  4. Supports Lockup Calculations – WIP + Debtors = Total lockup days.

  5. Drives Better Billing Habits – Encourages regular time entry and faster billing cycles.



🔍 How to Use a WIP Report Effectively:

  • Review weekly or fortnightly to stay on top of billables.

  • Sort by age to flag stale or forgotten time.

  • Discuss in team meetings to reduce aged WIP and improve cash conversion.

  • Bill progressively instead of waiting for matter completion.



💡 WIP Tip:

If your WIP is consistently high, you might have:

  • Time not getting billed

  • Bottlenecks in your billing process

  • Clients unaware of accruing fees

  • Scope creep with no additional invoicing



📊 WIP Report + Cash Flow = Power Combo

Use your WIP report alongside your Aged Receivables and Payments Received reports to monitor:✔ What’s been worked✔ What’s been billed✔ What’s been paid
