Construction and general contractor accounting — WIP schedules, AIA billing, subcontractor compliance
Industry: General Contractors

Built for the Way
Contractors Work

You're managing project managers, subcontractors, draw schedules, and change orders — all while trying to understand if you're actually making money.

Most accountants understand debits and credits. We understand WIP schedules, AIA billing, and what happens when a subcontractor walks off a job in week eight.

The Real Challenges

What Keeps GCs Up at Night

These aren't generic accounting problems. They're construction-specific financial challenges that require someone who knows the industry.

WIP Accounting

Most bookkeepers don't understand Work-in-Progress schedules. We do — and we build them correctly from day one so your financials actually reflect where each project stands.

Cash Flow Gaps Between Draws

You're waiting on owner draws while payroll, materials, and subs are due now. We build 13-week cash flow forecasts that show exactly when the gaps are coming — so you can act before the crisis hits, not after.

AIA Billing & Draw Schedules

Slow or inaccurate billing directly delays your draws. We set up AIA G702/G703 processes so you invoice correctly, get paid faster, and keep lenders and owners confident in your reporting.

Subcontractor Compliance & COIs

Expired certificates of insurance, missing W-9s, lien waiver tracking, 1099 compliance — managing a roster of subs is its own full-time job. We build the systems that keep you protected and audit-ready.

Subcontractor Payment Timing

Pay subs too early and you're funding their operations. Pay too late and they walk. We help you structure payment terms and cash flow schedules that keep the job moving without straining your liquidity.

Job Costing & Profitability

Winning bids means nothing if you don't know which jobs made money. We implement job costing that shows you exactly where margin lives — by project, phase, and cost code.

Change Order Financial Impact

Change orders are revenue — but only if they're tracked, billed, and collected. We make sure every approved change order flows correctly through your books and doesn't disappear into overhead.

Bonding & Lender Readiness

Surety bonds and construction loans require clean, credible financials. We prepare your books to pass underwriting — because our founder has been on the other side of that desk.

The Goal

What a Well-Run GC Looks Like

This is what we build toward — a financial infrastructure that gives you clarity, credibility, and control at every stage of a project.

WIP Schedule Updated Monthly

You know the over/under-billed position on every active project before your lender asks.

Cash Flow Visible 13 Weeks Out

Draw timing, sub payments, and payroll are mapped so you never get caught short between milestones.

Job Costing by Phase & Cost Code

You know which jobs made money and which didn't — before the next bid goes out.

Subcontractor Compliance Current

COIs, W-9s, lien waivers, and 1099s are tracked and current. No scrambling at year-end or during audits.

Financials Bank & Bond Ready

Your CPA-reviewed financials are presented the way lenders and surety companies want to see them.

Owner Has Real-Time Visibility

A monthly dashboard shows revenue, margin by project, and cash position — no more waiting for tax season to understand the year.

Why 406 Consulting Group

We Don't Just Read
Your Financials —
We Understand the Job

Construction finance is a specialty. The combination of project management experience, commercial lending background, and construction-specific accounting expertise is rare. We bring all three.

“Most accountants tell construction companies to find a specialist. We are the specialist.”

1

We Understand WIP

Work-in-Progress accounting is one of the most misunderstood areas in construction finance. Overstating or understating WIP distorts your financial picture and can trigger covenant violations with lenders. We build WIP schedules correctly and explain what they mean.

2

Project Management Runs in Our DNA

Our team brings deep project management experience from the oil and gas industry — one of the most operationally complex environments in the world. Scope control, cost tracking, schedule pressure, and stakeholder reporting translate directly to construction. We don't just read your financials; we understand the operations behind them.

Carrie Knows What Your Bank Needs

Our founder spent years in commercial lending — reviewing spreads, analyzing credits, and structuring SBA participation loans. When you need a construction loan or a line of credit, she knows exactly how to present your financials to get approved.

BuilderTrend Certified

We've done full BuilderTrend implementations and migrations — not just basic setup, but complete integrations with QuickBooks, job costing configuration, and team training. If you're moving to BuilderTrend or struggling with your current setup, we've been there.

Where Are You Right Now?

What Are You Trying to Solve?

Not every GC has the same problem. We work with contractors at every stage — from first-year builders to $40M operators preparing for a sale.

01

Get the Books Right

You're doing real volume but your books are a mess — job costing doesn't exist, WIP has never been done, and you're not sure what you actually made last year. We start here: clean books, correct chart of accounts, and a WIP schedule that reflects reality.

Signs You're Here
No job costing or cost codes
WIP schedule never prepared
Can't get bonded or financed
Tax season is always a scramble
02

Get Control of Cash Flow

You're profitable on paper but constantly short on cash. Draw timing, sub payments, and payroll don't line up. We build the 13-week cash flow forecast that shows you exactly when the gaps are coming — and gives you time to act.

Signs You're Here
Cash crunches between draws
Subs paid before owner draws arrive
Line of credit used for operations
No visibility beyond 30 days
03

Build for Growth or Exit

You've built something real and you want to scale it — or sell it. Either path requires financial systems that run without you in the loop, clean multi-entity structure, and financials that hold up to lender or buyer scrutiny.

Signs You're Here
Owner still reviews every invoice
No management reporting layer
Multi-entity complexity growing
Thinking about sale or succession

Not sure which stage you're in? That's the most common answer we hear. Start with a Business Readiness Review — we'll tell you exactly where we'd focus first.

Real-World Result

From Operational Chaos to Scalable Growth

5x
Revenue growth
$8M→$40M
Revenue scaled
80%
Less owner involvement

A construction firm came to us managing job costing chaos, retainage tracking issues, WIP reporting gaps, and multi-entity complexity — all while the owner was buried in day-to-day operations.

We built the financial infrastructure from the ground up. The result: revenue scaled from $8M to $40M, and the owner reduced their direct involvement by 80% — because the systems finally ran without them.

Before 406
WIP schedule done at year-end (if at all)
Owner reviewing every invoice personally
No idea which jobs were profitable
Cash flow surprises every month
Financials not bankable or bondable
After 406
WIP schedule updated monthly, lender-ready
Systems run without the owner in the loop
Job costing by project, phase & cost code
13-week cash flow forecast always current
Financials structured for bonding & growth

Illustrative Engagement

What a Typical Engagement Looks Like

The following is a representative scenario based on the types of challenges we commonly address with general contractors. It is not a specific client case.

The Situation

A commercial GC at $6–12M in revenue is winning more work but struggling to understand why cash is always tight. The owner is reviewing every invoice personally, job costing is done at year-end (if at all), and the WIP schedule hasn’t been touched since the last bank review.

The financials are technically accurate but not structured for bonding, bank financing, or owner decision-making. The business is growing — but the infrastructure isn’t keeping up.

What 406 Addresses
Job Costing: Per-project P&L by phase and cost code — so the owner knows which jobs make money before the final invoice
WIP Reporting: Monthly WIP schedule updated and lender-ready — not a year-end scramble
Cash Flow Visibility: 13-week rolling forecast that accounts for retainage, billing cycles, and equipment timing
Financing Readiness: Financials structured for bonding capacity and bank line renewals — not just tax compliance
Reporting Cadence: Monthly close process with owner-facing dashboard — decisions made on current numbers, not last quarter’s

Client Testimonials

What Contractors Say

We were running blind on job costs. 406 built us a WIP schedule and monthly P&L by project. I finally know which jobs are making money before they close.

Mike T.
General Contractor, $14M revenue, Montana

They got us bank-ready in 60 days. Our previous CPA had never heard of a borrowing base certificate. 406 knew exactly what the lender needed and delivered it.

Common Questions

Questions We Hear from Contractors

Do you work with contractors who use BuilderTrend?
Yes — we do full BuilderTrend implementations including data migration, QuickBooks integration, job costing configuration, and team training. We also support contractors who are already on the platform and need help getting more out of it.
What is WIP accounting and why does it matter?
Work-in-Progress (WIP) accounting tracks the financial status of projects that span multiple accounting periods. Without it, your income statement can show wildly inaccurate results — making a profitable month look like a loss, or hiding a problem until it's too late. Lenders and bonding companies require accurate WIP schedules.
Can you help us get bonded or qualify for a construction loan?
Absolutely. Our founder has a commercial lending background and knows exactly what surety companies and banks need to see. We prepare your financials specifically for underwriting review — not just for tax compliance.
We're growing fast and our books are a mess. Where do we start?
Start with a Financial Health Checkup — a fixed-price advisory project where we review your current setup, identify the biggest risks and gaps, and give you a prioritized action plan. Most contractors are surprised by what we find.
Do you work with contractors outside of Montana?
Yes. We serve construction companies remotely across the Mountain West, Pacific Northwest, and nationally. Our team is set up for remote collaboration — video calls, cloud-based software, and real-time reporting.
