3 Workflows to Turn Your Accounting Data into Accurate WIP Reports

You're tracking every cost. Every invoice. Every hour worked. But when someone asks, "Are we making money on this job?" you still can't give a confident answer.

The problem isn't your accounting software. QuickBooks and Sage capture everything. The problem is those transactions sit there like puzzle pieces scattered data that never becomes a clear picture of profitability.

Most contractors discover they've lost money on a job weeks after it's too late to fix anything. That ends today.

Here are three workflows that transform your existing accounting data into WIP reports that actually drive decisions and protect your margins.

Why Your Current Approach Fails

You're likely caught in one of these traps:

The Spreadsheet Trap: You export data monthly, spend hours reformatting in Excel, and by the time you finish, the information is outdated. One formula error means everything is wrong.

The Month-End Trap: Your bookkeeper closes the books, runs reports, and discovers you lost $40,000 on a job that finished three weeks ago. Too late to course-correct.

The solution isn't working harder or buying more software. It's implementing three systematic workflows that make your accounting system do the heavy lifting.

1. Daily Job Cost Capture & Categorization

The Core Problem: Costs hit your system randomly lumber on Tuesday, payroll Friday, equipment rental next week. Without disciplined capture, your WIP report is just guessing.

Step 1: Build Your Foundation (One-Time Setup)

Before any workflow works, establish structure:

Create a cost code hierarchy matching your estimates:

• 01 - Site Work

• 02 - Foundations

• 03 - Concrete

• 04 - Framing

• 05 - Rough-Ins

Critical rule: If you estimate framing as code 04-100, use code 04-100 in accounting. Eliminate translation errors completely.

QuickBooks setup: Use Projects or Classes to track each job. Every transaction gets tagged to a specific project and cost code.

Sage setup: Use Cost Codes with Phase Codes. Map every general ledger account to a cost category in your Job Cost Budgeting module.

Step 2: The 15-Minute Daily Review (Every Morning at 9 AM)

This catches errors before they compound:

1. Pull yesterday's transaction detail report

2. Scan for items coded to "Overhead" or "Miscellaneous"

3. Verify cost codes match actual work performed

4. Flag duplicate entries (common with credit card charges)

5. Recode any errors immediately

QuickBooks path: Reports > Jobs, Time & Mileage > Job Profitability Detail Filter: Yesterday's date

Sage path: Reports > Job Cost > Daily Transaction Register Sort by: Cost Code

Step 3: Establish Clear Entry Rules

Eliminate ambiguity about who does what:

• Accounts Payable/Bookkeeper: Codes all vendor bills to jobs and cost codes within 24 hours

• Project Managers: Submit change orders and time cards daily (not weekly)

• Field Teams: Photograph and submit expense receipts same-day via mobile

Step 4: Set Automated Alerts

Configure your system to notify you when:

• Any single transaction exceeds $5,000 (catches data entry typos)

• A job's costs hit 80% of budget

• Costs post to jobs with no established budget

The Result: You catch and correct coding errors within 24 hours instead of 30 days later. Your WIP data stays 95% accurate in real-time. When you run a WIP report, you can trust the numbers.

2. Weekly Revenue Recognition & Over/Under Billing Analysis

The Core Problem: You billed $100,000 last month, but have you actually earned it? Without proper revenue recognition, your WIP shows fantasy profits instead of real performance.

Step 1: Calculate Percent Complete (Every Monday Morning)

Choose your measurement method and apply it consistently:

Cost-to-Cost Method (most common for contractors):

Formula:

Example:

• Costs spent: $150,000

• Total budget: $500,000

• Percent complete: 30%

Units Method (best for repetitive work):

Formula: (Units Completed ÷ Total Units) × 100 = % Complete

Example:

• Apartments finished: 45

• Total units: 150

• Percent complete: 30%

QuickBooks: Create a custom field called "Percent Complete" in each Project. Update weekly from your job cost summary report.

Sage: Use the "% Complete" field in the Job Cost Budgeting module. Update through Job Master File.

Step 2: Calculate Earned Revenue

This is where accounting meets reality:

Formula: 

Using our example:

• Contract amount: $600,000

• Percent complete: 30%

• Earned revenue: $180,000

This is what you've actually earned based on work performed, regardless of what you've billed.

Step 3: Determine Over/Under Billing Position

Compare earnings to billings:

Formula:

Continuing our example:

• Total billed to date: $220,000

• Earned revenue: $180,000

• Over-billed by: $40,000

What these numbers mean:

Over-billed (positive number): You've billed more than you've earned. This creates a balance sheet liability you owe the owner work. Risk: If the job goes sideways, you may have to return money.

Under-billed (negative number): You've earned revenue you haven't billed yet. This is a balance sheet asset the owner owes you money. Opportunity: Submit your next invoice immediately.

Step 4: Record the Accounting Adjustment

Every Monday, adjust your books to reflect earned versus billed:

If Over-Billed:

Debit: Billings in Excess of Costs (Balance Sheet Liability)

Credit: Construction Revenue (Income Statement)

If Under-Billed:

Debit: Costs in Excess of Billings (Balance Sheet Asset)

Credit: Construction Revenue (Income Statement)

QuickBooks: Create these entries through Make General Journal Entries. Always tag with job name in the memo field for tracking.

Sage: Post through General Journal Entry screen, coding to the appropriate job number.

Step 5: Build Your Weekly WIP Dashboard

Create a simple one-page view that tells the whole story:

The Result: Every Monday morning, you know exactly which jobs are over-billed (financial risk) and under-billed (billing opportunity). No more guessing. No more surprises. Just clear data that drives action.

3. Monthly Variance Analysis & Estimate-to-Complete Updates

The Core Problem: Your WIP report says you're profitable, but you're burning through budget faster than planned. Without variance analysis, you won't see the cliff until you've driven off it.

Step 1: Generate Cost Variance Report (First Monday of Each Month)

Pull the critical comparison data:

QuickBooks path: Reports > Jobs, Time & Mileage > Job Estimates vs. Actuals Detail Customize to show: Original Budget, Actual Costs, Variance $, Variance % Filter: All active jobs

Sage path: Job Cost Report > Budget vs. Actual Cost Report Include columns: Budgeted Cost, Actual Cost, Variance, % of Budget Used, % Complete

Step 2: Identify Red Flag Variances

Scan for these critical warning signs:

Immediate attention required:

• Any cost category more than 10% over budget when job is less than 50% complete

• Labor costs tracking more than 20% over estimate

• Any single negative variance exceeding $10,000

Real example:

• Framing budget: $85,000

• Job completion: 40%

• Expected costs at 40%: $34,000 ($85,000 × 40%)

• Actual costs: $62,000

• Red flag: You're 82% over expected pace

Step 3: Drill Down to Root Causes

For each major variance, investigate why:

QuickBooks: Click the variance amount to see transaction detail. Look for:

• Price increases (lumber went from $500 to $750/unit?)

• Scope creep (extra work without approved change orders?)

• Productivity issues (framing taking 50% longer than estimated?)

• Coding errors (costs accidentally assigned from another job?)

Sage: Use the Job Cost Transaction Drill-Down feature to review line-item detail for problematic phase codes.

Step 4: Update Your Estimate-to-Complete

This is the most critical step revise what you think the job will actually cost:

Formula: Revised Total Cost = Actual Costs to Date + Revised Estimate to Complete

Using our framing variance:

• Actual costs to date: $62,000

• Original budget remaining: $23,000

• Realistic estimate for remaining work: $93,000 (based on actual pace)

• Revised total cost: $155,000 ($62,000 + $93,000)

• Original budget: $85,000

• Projected loss on framing: $70,000

Step 5: Recalculate Earned Revenue with Revised Numbers

Update your percent complete using realistic estimates:

New calculation: Actual costs $62,000 ÷ Revised budget $155,000 = 40% complete

Impact on revenue recognition:

• Old calculation: $600,000 contract × 45% = $270,000 earned

• New calculation: $600,000 contract × 40% = $240,000 earned

• Required adjustment: Reduce recognized revenue by $30,000

Your WIP report now shows reality, not hope.

Step 6: Take Immediate Action

Armed with accurate forecasts, make decisions while you still have options:

If projecting a loss:

• Stop work immediately and renegotiate scope (if contract allows)

• Submit all pending change orders today, not next week

• Replace underperforming crews or upgrade equipment

• Document every delay for potential claim or dispute

If projecting strong profit:

• Replicate successful practices on struggling jobs

• Consider accelerating schedule to lock in margins before conditions change

• Bill for under-billed amounts to improve cash position

Step 7: Communicate Updated Forecasts

Share your WIP insights with stakeholders:

For Owners/General Contractors: Updated percent complete, amounts billed, revised completion timeline

For Lenders/Bonding Companies: Current cost-to-complete estimates, projected profit margins, cash flow forecast

For Internal Team: Which jobs need urgent attention, which are performing well, lessons learned

The Result: You're no longer discovering problems after they've destroyed profit. You see trends developing with enough time to protect your margins. You make decisions based on data, not hope.

Making These Workflows Permanent

Good intentions don't change businesses. Systems do. Here's how to make these workflows stick:

Assign Clear Ownership

• Daily Job Cost Capture: Bookkeeper or AP coordinator

• Weekly Revenue Recognition: Project manager or controller

• Monthly Variance Analysis: Company owner or CFO

Don't let workflows be "everyone's responsibility" that means they're nobody's responsibility.

Block Calendar Time (Non-Negotiable)

• Daily: 15 minutes at 9:00 AM for cost review

• Weekly: 1 hour Monday mornings for revenue recognition

• Monthly: 2 hours first Monday for variance analysis

Treat these like client meetings. They're that important.

Create Simple Checklists

Don't rely on memory. Build a checklist for each workflow and physically check boxes as you complete steps. Print it. Laminate it. Follow it.

Leverage Software Automation

Both QuickBooks and Sage offer features that reduce manual work:

• Schedule reports to run automatically and email to your inbox

• Set up recurring journal entries for common revenue adjustments

• Integrate third-party apps (Siteline, Billd, Foundation) that connect to your accounting software and automate WIP calculations

The Bottom Line

Your QuickBooks or Sage system already captures everything needed for accurate WIP reporting. The missing piece was never the data it was the systematic workflows to transform entries into insights.

These three workflows daily cost capture, weekly revenue recognition, and monthly variance analysis give you a repeatable process. They turn accounting data into profitability intelligence you can trust and act on.

Start with Workflow 1 this week. Master it for 30 days before adding Workflow 2. Within 90 days of implementing all three, you'll have real-time visibility into every job's true performance.

No more month-end surprises. No more wondering if you're making money. No more discovering problems after they're unfixable.

Just clear, accurate, actionable data that helps you build a more profitable construction business.
