CONSTRUCTION

Maximize profits on every job

Between retainage, progress billing, and tracking costs across multiple projects, construction accounting gets complicated fast. We help contractors know their real numbers to ensure profitability.

The numbers that help contractors sleep at night

With our proactive support, you’ll be equipped to bid jobs with a clear picture of the estimated costs. We can develop a strategy that will help you accurately calculate material, labor, and subcontractor expense to increase your profit margin.

As our client, you’ll always have access to our team for advice during any stage of a project. Our guidance will give you a clear view of job profitability and put your whole business on a path to financial security and long-term success.

COMMON CHALLENGES

Juggling too much? We’ll help you catch the balls.

Job costs that don’t make sense? Materials, labor, equipment, subs—costs are spread across multiple projects. We’ll keep your books up-to-date to show exactly where the money is going for each job.

Cash flow gaps between projects? With our project tracking, there will be no more waiting on progress payments while you have to pay for materials and labor on the next job. Our goal is to eliminate delayed payments.

Billing that falls behind? Progress billing, change orders, and retainage won’t be an issue. Invoices will go out on time, and payments will come in sooner.

Growth that feels risky? If you want to take on bigger projects, you’ll have 24/7 access to your financial data. Our reporting will help you understand the capability of your margins, so you’ll know if you have the cash to cover costs upfront.

THE SOLUTION

What if you knew your numbers in real time?

That’s what our virtual CFO model gives you: real-time job costing, cash flow forecasting that accounts for payment cycles, progress billing that happens on schedule, and strategic guidance from a team that understands construction margins aren’t like other businesses.

Know which jobs make money—while you can still fix the ones that don’t

Track costs by project in real time. See exactly where you stand on labor, materials, equipment, and subcontractors. Get alerts when costs are trending over budget before it kills your margin.

We set up your systems to capture costs correctly from the start, then deliver regular reports showing actual profitability by job—not just what you hoped it would be.

Stop funding new jobs with money you haven’t collected yet

We forecast your cash needs based on project timelines, payment schedules, and retainage. You’ll know exactly when money’s coming in and going out—so you’re never scrambling to cover payroll or materials.

Progress billing happens on schedule. Retainage gets tracked and collected. And we help you build cash reserves so one slow-paying client doesn’t shut down your business.

Get paid faster with billing that actually goes out on time

We handle progress billing, change order tracking, and retainage so invoices go out consistently. Then we stay on top of collections—because invoicing doesn’t matter if you’re not getting paid.

You’ll always know who owes what and how long it’s been outstanding. No more surprise cash crunches because billing fell behind.

Take on bigger projects without the bigger risk

Before you bid that next big job, we help you understand the cash requirements, margin pressure, and bonding implications. Can you actually handle it profitably? We’ll show you the numbers.



As you grow, we help you maintain margins, optimize equipment purchases, and plan for seasonal fluctuations. Growth is great—if it’s profitable.

Structure your business to keep more of what you make


Construction has unique tax planning opportunities—equipment depreciation, Section 179 deductions, proper entity structure. We help you maximize deductions while planning for tax bills before they surprise you.

Year-round planning means you’re making strategic decisions about equipment purchases, hiring, and profit distribution based on tax impact.

WHAT OUR CONSTRUCTION CLIENTS ARE SAYING

“When you’re growing fast, revenue can hide a lot of problems. PrimeNumbers stepped in and stripped everything down to the studs. They challenged our assumptions, broke apart our cost structure, and showed us exactly what it would take to run this company profitably — not just aggressively. They brought discipline to our financials and accountability to our decisions. Every founder needs someone willing to tell them the real story behind the numbers. That’s what they’ve been for us.”

Common questions from contractors

How do you handle job costing for multiple projects?

We set up your accounting system to track costs separately for each job—labor, materials, equipment, subcontractors, and overhead. You’ll get regular reports showing actual costs versus estimates so you can spot problems early. Every expense gets coded to the right job from day one, giving you accurate profitability numbers in real time instead of waiting until a project closes to see if you made money.

Can you help with progress billing and retainage tracking?
Absolutely. We handle progress billing schedules, making sure invoices go out on time based on completed work. Retainage gets tracked by project, so nothing falls through the cracks when it’s time to collect. We also manage change order billing and make sure you’re documenting everything properly to avoid payment disputes. Our goal is to get you paid faster and eliminate cash flow gaps between projects.
What's the difference between a regular accountant and a virtual CFO for construction?
A regular accountant records what happened last month. A virtual CFO helps you manage what’s happening right now and plan for what’s coming next. We focus on job profitability, cash flow forecasting, and strategic decisions like which projects to bid, when to buy equipment, and how to scale without killing your margins. We understand construction-specific challenges like retainage, bonding, and seasonal fluctuations—not just generic small business accounting.
How quickly can you help us get better job costing data?
Implementation typically takes 2-4 weeks, depending on your current systems. We start by auditing how you’re currently tracking costs, then set up proper job costing in your accounting software. We’ll train your team on how to code expenses correctly and establish processes for tracking time, materials, and subcontractor costs. Most contractors see meaningful improvements in their financial visibility within the first 30-60 days.
Do you work with construction companies outside of North Dakota?
Yes, our virtual CFO platform works anywhere. While we’re based in Fargo, ND, we serve construction companies regionally and have systems in place for remote collaboration. Cloud-based accounting means we can access your financials in real time, regardless of location. We handle multi-state tax compliance and understand regional variations in construction accounting practices.
