    Managing Unbilled Value and Budget Drift

    When you finish a high-stakes week of delivery, the biggest risk to your margin isn't the work itself—it’s the gap between the effort your team expended and the revenue currently sitting in your bank account. Without clear visibility, unbilled time persists as "ghost" inventory, and small deviations in scope can quietly erode your project profitability before you have a chance to course-correct.

    AtomicSam bridges the gap between daily activity and commercial outcomes through Work-in-Progress (WIP) and Variance reporting. By transforming raw timesheet data into actionable financial metrics, you gain the confidence to bill accurately and protect your margins in real-time.

    Protecting Your Realized Revenue

    The WIP Report is your primary tool for preventing revenue leakage. It quantifies the total value of approved time and expenses that have been recorded against a project but have not yet been converted into an invoice. This report ensures that no billable hour is forgotten and that your cash flow matches your team's output.

    The Variance Report, conversely, focuses on the health of your fixed-fee or capped projects. It compares your original budget estimates against the actual costs incurred to date. This allows you to identify "burn" trends early, giving you the commercial control needed to renegotiate scope or adjust resources before a project enters the red.

    💡 Tip: Run your WIP report every Thursday afternoon. This gives you a clear window into what can be invoiced before the month-end close, preventing the "Friday rush" that often leads to billing errors.

    Choosing Your Management View

    Depending on your role—whether you are a Project Manager watching a specific budget or a Finance Director managing firm-wide liquidity—you will need to pivot between these two views.

    Use this report when... Required Metric Commercial Outcome
    You need to see exactly how much unbilled revenue is sitting on the books. WIP Value Improved cash flow and reduced billing lag.
    A client asks why a project is nearing its budget cap earlier than expected. Budget vs. Actual (BvA) Data-backed scope negotiations and margin protection.
    You want to identify which team members are over-delivering on hours relative to task estimates. Task Variance More accurate future quoting and resource allocation.
    ⚠️ Heads up: Expenses often lag behind time entries. Ensure your team has uploaded all vendor receipts before running a final WIP report to avoid under-billing for project disbursements.

    How to Generate the WIP Report

    1. Navigate to the Reports module in the primary sidebar.
    2. Select Financials and click on WIP Valuation.
    3. Apply your filters:
      • Client/Project: Isolate specific accounts or view the entire firm.
      • Date Range: Choose "As of" to see the total current balance, or a specific range to see what was earned last month.
      • Status: Filter for "Approved" entries only to ensure you are looking at verified data.
    4. Click Generate. AtomicSam will calculate the value based on the specific rate cards assigned to those projects.

    How to Analyze Project Variance

    1. From the Reports dashboard, select Variance & Budgeting.
    2. Select the specific project you wish to audit.
    3. Toggle between Value (Monetary) and Units (Hours). Viewing variance in hours is often more effective for managing creative teams, while value is preferred for executive reporting.
    4. Review the Task-Level Breakdown to see exactly which phase of the project is driving the overage.
    ✅ Did you know: AtomicSam allows you to set "Tolerance Alerts." You can configure the system to notify a Project Manager via email the moment a project hits 75% of its budgeted variance.

    Pro Tips for Professional Services Leaders

    • The "WIP Age" Audit: Don't just look at the total WIP value—look at the age. If time entries are sitting in WIP for more than 45 days, it usually indicates a dispute with the client or a lack of documentation. Address these "stale" entries immediately to prevent them from becoming write-offs.
    • Internal vs. External Variance: Use the Variance report to distinguish between "Scope Creep" (the client asked for more) and "Execution Drag" (the team took longer than estimated). This distinction is vital for accurate post-project reviews and improving your firm's pricing confidence.
    • Watch the "Cost WIP": While most firms focus on the billable value, checking your "Cost WIP" (the actual salary cost of the hours worked) gives you a truer picture of your immediate financial exposure before the invoice is even sent.
