If you've ever applied for a construction bond, opened a line of credit with a construction lender, or filed taxes with a CPA who actually understands construction, you already know that all three want the same document: your construction WIP report. WIP — work in progress — is the single report that tells outside parties whether your firm has its books under control. The surety underwriter pulls it before any other financial document. The bank pulls it before approving the credit line. The CPA pulls it before signing the tax return. And yet most contractor owners we talk to don't really understand what their own WIP report is saying.
This guide fixes that. Written for contractor owners — not accountants — we cover what a construction WIP report actually is, the five numbers every owner should look at first, what underbillings and overbillings mean for your cash position, the 15-step monthly close process CCA runs to produce clean WIP schedules, and what your surety/bonding agent/lender is actually looking for when they read your WIP. The goal: give you the same plain-English understanding of work in progress construction reporting that we give CCA clients the first time we walk them through their own monthly schedule.
This is the third blog in our 2026 construction bookkeeping series. See also: Construction Cost Codes 2026 → [link to: /post/construction-cost-codes-2026-guide] for the cost code structure that feeds your WIP. And Construction Job Costing Reports 2026 → [link to: /post/construction-job-costing-reports-2026-guide] for the four monthly reports that work alongside WIP. All three connect: cost codes capture the data, job costing reports help you read individual project performance, and the WIP schedule rolls everything up into the picture your surety, lender, and CPA need.
What a Construction WIP Report Actually Is (In Plain English)
A WIP schedule construction report is a one-page snapshot — usually a spreadsheet — that shows every active job in your firm and answers four questions for each one:
What's the total contract value (including change orders)? — what the customer agreed to pay you for the entire job
What's the estimated total cost to complete the job? — what you think the whole job will cost from start to finish
How much have you spent on this job so far? — cumulative job costs to date
How much have you billed the customer so far? — cumulative billings to date
From those four numbers, the WIP schedule calculates: gross profit (contract minus estimated cost), gross profit percentage, percent complete (costs to date divided by total estimated cost), revenue recognized using percentage-of-completion accounting (contract value times percent complete), and the two numbers that most directly reflect your cash position — underbillings (costs in excess of billings) and overbillings (billings in excess of costs). Modern work in progress construction reporting standardizes this calculation so the same job financial position can be read consistently month over month.
If that sounded like jargon, here's the plain-English version: the work in progress accounting approach treats every active construction job as a real-time financial position, not a guess. Every month, your bookkeeper enters where each job stands — what you spent, what you billed, what the customer owes you for change orders, what the PM estimates the total cost will be. The schedule does the math: how complete each job is, how much revenue you've actually earned (versus how much you've billed), and whether you're funding work the customer hasn't paid for yet (underbillings) or sitting on cash from work that hasn't been done yet (overbillings).
FROM THE OWNER'S CHAIR: The single biggest reason contractor owners struggle with WIP is that nobody ever explained it to them in plain English. Once you understand that WIP is just 'where every active job stands financially this month,' the whole report becomes useful. Without that understanding, it just looks like another spreadsheet from the bookkeeper. |
The 5 Numbers Every Owner Should Read First on Their WIP Report
When you pull your construction WIP report each month, don't try to read every column. Focus on these five numbers first. They tell you everything you need to know about whether your firm is healthy or in trouble:
1. Net Underbillings or Overbillings Position
This is the single most important number on your WIP schedule. Add up construction underbillings across all active jobs (positive number — money you've spent but not yet billed for) and subtract construction overbillings (negative number — money you've billed but not yet earned). The net tells you whether your active job portfolio is using up your cash or generating it. Net underbilled means you're funding work the customer hasn't paid for. Net overbilled means you're sitting on customer cash for work not yet delivered.
2. Gross Profit Percentage by Job
Per-job gross profit % — calculated as gross profit divided by contract value. Compare each active job against your firm's target margin. A job tracking below your target needs investigation NOW, not at completion. The point of monthly WIP is catching margin slippage while you can still influence the outcome.
3. Percent Complete vs Percent Billed
For each job, compare 'percent complete' (costs to date divided by total estimated cost) against 'percent billed' (billings to date divided by contract value). These should track close to each other. If percent complete is 70% but you've only billed 50%, you're funding 20% of the job out of your own pocket — that's underbillings. If you've billed 80% and you're only 50% complete, you've borrowed 30% from the customer — that's overbillings.
4. Revenue Backlog
Contract value minus revenue recognized to date. This is the total work you have remaining to perform across all active jobs. Your construction percentage of completion backlog is your future revenue pipeline. Compare it to your monthly burn rate to know how many months of work you have ahead of you. Low backlog with a high burn rate is a problem. High backlog with a low burn rate means you're under-resourced for the work you've sold. Backlog is also one of the first metrics sureties pull when evaluating bonding capacity — your construction percentage of completion remaining tells them how much work the firm has committed to deliver.
5. Total Job Costs vs Total Estimated Costs (by Job)
For any job that's more than 50% complete, compare costs to date against total estimated cost. If costs to date already exceed 70-80% of estimated total cost when you're only 50% complete, you're heading for a margin disaster on that job. This is the early warning system. Catch it at 50% complete and you have options. Catch it at 90% complete and you're just managing the loss.
OWNER'S TAKEAWAY: Five numbers. Three minutes per month. If you do nothing else with WIP, do these five reads. You'll catch 80% of the problems most contractor owners miss until they show up six months later in the bank account. |
Underbillings vs Overbillings — What They Actually Mean for Your Cash
This is where most contractor owners get confused — and where the WIP schedule pays the biggest dividends in plain understanding. Construction underbillings and construction overbillings are not just accounting terms — they describe whether your customer or your bank account is funding your work.
Underbillings (Costs in Excess of Billings)
Underbillings happen when the work you've done on a job exceeds what you've billed the customer for. Mathematically: costs to date are at, say, 60% of estimated total cost, but you've only billed 40% of the contract value. The 20% gap is underbillings — work you've performed and paid for (labor, materials, subs) but haven't recovered through customer invoices.
Underbillings mean:
YOU are funding the work — not the customer. The cash to pay your crew, suppliers, and subs is coming out of your operating account, not coming in from the customer.
Often caused by — invoicing lag (work done in October but invoice not sent until November), under-billing on AIA progress invoices, change orders performed before being formally approved, or just lazy invoicing discipline.
Action — get invoices out THIS WEEK. Every week of underbilling sits in your AR pipeline for an extra 30-45 days before payment, and that's real cash you're financing.
Overbillings (Billings in Excess of Costs)
The opposite. You've billed the customer for more than the work performed so far. Mathematically: you've billed 60% of the contract value but costs are only at 40% of estimated total cost. The 20% gap is overbillings — customer money sitting in your account for work not yet done.
Overbillings mean:
The CUSTOMER is funding your work — good for short-term cash, but you owe that performance back. The cash isn't yours; it's a liability until you do the work.
Often caused by — front-loaded billing schedules, large mobilization deposits, materials billed before installation, contractual milestone billings ahead of execution.
Action — watch for customer pushback on the next billing cycle when the customer's CPA notices the gap. Make sure your job execution catches up to your billing pace. Don't treat overbilling cash as profit — it's borrowed from the customer.
⚠ RED FLAG: The single most dangerous WIP pattern: high overbillings on most jobs, while one or two large jobs run hidden underbillings. The overbillings create the illusion of cash strength while the underbillings drain it slowly. Net position can flip from healthy to dangerous in a single quarter if you're not watching. |
CCA's 15-Step Monthly WIP Close Process
Producing a defensible WIP schedule construction report every month requires a structured process — not improvisation. CCA runs the same 15-step monthly close for every contractor client, grouped into five phases. This is the actual production checklist used to produce clean monthly WIP schedules.
CCA'S 15-STEP MONTHLY WIP CLOSE PROCESS
The structured monthly process that produces a defensible WIP schedule — same workflow every month, no improvising
PHASE 1: POSTING |
|
PHASE 2: GATHER ACCOUNTING DATA |
|
PHASE 3: GATHER PM/ESTIMATOR INPUT |
|
PHASE 4: REVIEW + VALIDATE |
|
PHASE 5: CLOSE + RECONCILE |
|
Why 15 Steps Matter
Each step in this process exists because of a specific failure mode it prevents. Skipping Phase 1 (posting) means your WIP is built on incomplete data. Skipping Phase 3 (PM/Estimator input) means the schedule reflects accounting numbers but ignores field reality. Skipping Phase 4 (review) means errors flow through to the financial package. Skipping Phase 5 (close/reconcile) means your WIP doesn't tie to the financial statements, which fails any third-party review — surety, lender, or CPA.
The construction job billing report referenced in Step 4 of the process pulls cumulative billings by job — this is the source data that flows into the WIP schedule's billing columns. The job profitability or job cost report in Step 3 does the same for costs. Both reports — the job cost report and the construction job billing report — are standard outputs of any properly configured construction accounting system, including QuickBooks Online with cost codes set up correctly (see Cost Codes Blog #1).
Your Surety Wants a WIP Report. Don't Hand Them a Mess.
Sureties, bonding agents, and construction lenders pull the WIP schedule before anything else when they evaluate your firm — and a messy, inconsistent, or stale WIP report tells them you don't have control over your business. CCA produces clean monthly WIP schedules for contractor owners as part of our construction bookkeeping services. In a 30-minute call, we'll review your current WIP process and tell you honestly whether it would survive a surety underwriter's first read.

Sample WIP Schedule Walkthrough — What an Owner Should See
Here's a real-world worked example based on CCA's construction WIP schedule template — Example Company with 5 active jobs as of 10/31. This is what an owner should be looking at every month:
SAMPLE WIP SCHEDULE — WHAT AN OWNER SHOULD SEE
Real-world example: Example Company at 10/31 month-end — 5 active jobs, $4.63M in contracts. Numbers you should look at first.
Job | Contract | Estimated Cost | % Complete | Under- billings | Over- billings |
ABC Building (brand new) | $1,000,000 | $880,000 | 7% | $63,864 | — |
XYZ Building (nearly done) | $550,000 | $475,000 | 95.8% | $200,842 | — |
DEF Building (not started) | $900,000 | $725,000 | 0% | — | — |
RST Building (mid-job) | $980,000 | $900,000 | 74.4% | $270,556 | — |
LMN Building (over-billed) | $1,200,000 | $1,000,000 | 47.5% | — | $235,000 |
TOTAL (5 jobs) | $4,630,000 | $3,980,000 | 41.8% | $535,261 | $235,000 |
NET WORKING CAPITAL POSITION | $300,261 UNDER-BILLED |

WHAT THIS WIP SCHEDULE IS TELLING YOU: 5 active jobs, $4.63M in contracts, 41.8% complete on average. CRITICAL: You are net under-billed by $300,261 — meaning you are funding $300K of work that you have not yet billed customers for. That's $300K out of your operating cash. Three jobs (ABC, XYZ, RST) need invoices sent THIS WEEK to recover cash. LMN is over-billed (good for cash, but watch for customer pushback at the next billing cycle).
What This Schedule Tells the Owner
Five jobs, $4.63M in total contracts, blended 41.8% complete. The headline number is the net working capital position: $300,261 net underbilled. The firm is funding $300K of work it hasn't yet billed customers for. Three jobs (ABC, XYZ, RST) carry the bulk of the underbillings — $535K combined. One job (LMN) is over-billed by $235K, which offsets some of the cash drain but creates exposure if the customer disputes the next billing cycle.
Owner decisions from this single schedule:
Get invoices out on ABC, XYZ, RST this week — $535K in unbilled costs is real cash drag
Watch LMN closely — when the customer's CPA sees 47.5% complete vs 67% billed, expect pushback at the next billing cycle
DEF Building hasn't started — mobilization deposit should already be invoiced (free cash)
XYZ Building is at 95.8% complete — final billing and retention release should happen within 60 days
A WIP schedule is just a one-page snapshot of where every active job stands. The work isn't in reading the schedule. The work is in the decisions the schedule should drive THIS week — invoices to send, customers to call, jobs to investigate. |
Why Sureties, Banks, and CPAs Look at Your WIP First
When a surety underwriter, construction lender, or external CPA reviews your firm, the WIP report for surety review typically comes before any other financial document. Here's what they're looking for:
Surety Underwriter Perspective
Bonding capacity — total backlog (remaining work to perform) and revenue history determine your single-job bonding capacity and aggregate program limit
Margin patterns — stable gross profit % across jobs signals predictability; volatile margins signal risk
Cash position health — net underbilling position signals working capital strain; net overbilling pattern with low cash signals trouble
Schedule discipline — a clean, internally consistent WIP schedule signals operational maturity; a messy or inconsistent one signals control issues
Construction Lender Perspective
Loan eligibility — working capital ratios calculated from the WIP schedule determine credit line size
Covenant compliance — existing credit facilities often have WIP-based covenants (debt to backlog, working capital minimums)
Future revenue visibility — backlog and percent complete projections feed cash flow models the lender uses to evaluate credit risk
CPA / Tax Return Perspective
Percentage-of-completion compliance — ASC 606 requires
Revenue recognition — matches the timing of revenue recognition to the timing of work performed, not invoice timing
Year-end adjustments — determines the journal entries to reconcile income statement gross profit to WIP-derived gross profit
Audit defensibility — under any CPA audit or review engagement, a clean monthly WIP schedule is the primary supporting documentation
OWNER'S TAKEAWAY: If you're a contractor owner planning to apply for bonding capacity, open a credit line, or file an audited financial statement, your monthly WIP discipline for the prior 12 months is what gets reviewed — not the WIP you produce the week before you apply. The time to get your WIP process right is now, not later. |
Common WIP Report Red Flags That Concern Outside Reviewers
Based on patterns CCA sees when cleaning up inherited WIP processes, these are the red flags that signal trouble — to a surety, a lender, a CPA, or to the owner if they spot them in time:
Jobs over 100% complete — costs to date exceeding total estimated cost. Either the estimate was wrong, the job is losing money, or the bookkeeper updated costs without updating estimates.
Jobs over-billed beyond contract — cumulative billings exceeding contract value. Means either revenue recognition error or unauthorized billing.
Large month-over-month swings — a job's gross profit % swinging 10+ points between months without a clear explanation signals data errors or estimate revisions worth investigating.
Negative gross profit — any job showing negative gross profit % is a known loss that needs management attention immediately.
Stale percent complete — percent complete not moving across months while costs are accumulating suggests the cost data or estimate is wrong.
Disconnect between WIP gross profit and P&L gross profit — step 15 of the close process exists for this reason. If WIP gross profit and income statement gross profit don't reconcile, the WIP schedule isn't trustworthy.
No prior-month comparison — WIP schedules submitted without prior-month columns make it impossible to spot trends. Always compare line by line.
⚠ RED FLAG: Sureties and lenders look specifically for these red flags. They have decades of pattern recognition. A contractor who submits a WIP with multiple jobs over 100% complete or large unexplained margin swings will get pushback — and possibly a reduced bonding capacity or credit line. The 15-step monthly close process exists to catch these before they leave your office. |

In 2026, the construction WIP report remains the single most important financial document a contractor produces. It's the report your surety underwriter reads first, the report your construction lender requires for credit line decisions, the report your CPA needs for tax compliance and any audit/review engagement, and — most importantly — the report YOU should be reading every month to know whether your active job portfolio is generating cash or quietly burning through it.
The contractor owners who manage WIP well share a common pattern: a defined monthly close process (the 15 steps above), the same five-number read every month, and a relationship with a construction bookkeeper who actually understands work in progress accounting — not a generalist who treats it as 'just another report.' The owners who struggle share the opposite pattern: WIP only produced when someone outside asks for it, no monthly discipline, no review process, and reports that don't reconcile to the financial statements when scrutinized.
Construction Cost Accounting produces clean monthly WIP schedules for contractor owners as part of standard construction bookkeeping services engagements. Our most common setup is construction WIP report QuickBooks — building the WIP schedule from QBO data with cost codes properly configured. For the cost code structure that feeds your WIP, see our 2026 construction cost codes guide. For the four monthly job costing reports that work alongside WIP, see our 2026 job costing reports guide.
