You Need a CPA That Understands Project-Based Work.

📉

Know Which Projects Actually Make Money

Having total revenue and total expenses isn't the same as knowing what each job costs. Factor in labor, materials, equipment, and subcontractors, and that number changes fast. Without that visibility, every bid, every resourcing decision, and every growth plan becomes an educated guess.

🔧

Stop Losing Tax Savings on Equipment

How you depreciate vehicles and heavy equipment affects your tax bill. Section 179 lets you deduct the full cost of qualifying equipment the year you buy it. Bonus depreciation and standard MACRS (Modified Accelerated Cost Recovery System) spread it out instead. Getting it wrong can mean paying more tax than necessary or missing valuable deductions.

💸

Make Your Financials Reflect Project Performance

Milestone billing, time-and-materials, fixed-fee, and percentage-of-completion contracts each require their own revenue recognition treatment. If your books only reflect what's been invoiced or collected, they can mislead you. An unprofitable project can look healthy, while a profitable one appears to be losing money.

🌍

Stay Ahead of Multi-State Tax Obligations

Every project in a new state can create additional income tax, payroll tax, and withholding obligations. Many growing contractors don't realize they've created a new filing obligation until a notice arrives. However, identifying those obligations early is almost always simpler and less expensive than fixing them after the fact.

How We Help You Grow

Every Financial Function You Need

📒

Bookkeeping & Reconciliation

See how each project is really performing, not just what's been billed. We close your books monthly. We also recognize revenue the way you actually bill: milestones, time-and-materials, fixed-fee, or percentage-of-completion. Work-in-progress gets reconciled against what's owed, so your financials reflect reality.

📊

Job Costing & Profitability Analysis

Know which projects are actually making you money. We'll build job costing that tracks labor, materials, equipment, and subcontractor costs at the project level. It connects directly to your field management software. That means you can bid, price, and plan the next job with confidence instead of a guess.

💰

Tax Planning, Preparation & Filing

Keep more of what you earn, legally and on purpose. We'll choose the right entity structure and plan equipment depreciation ahead of time, not after the fact. State filings and contractor 1099 compliance get the same treatment; however, it is all part of a strategy built around your business, not a return filed once a year.

🔧

Equipment & Fixed Asset Strategy

Turn equipment purchases into a tax advantage instead of an afterthought. We'll manage your full fixed asset schedule and decide between Section 179 and standard depreciation for each acquisition. Your fleet and technology assets stay tracked and coordinated across federal and state returns.

📊

Outsourced CFO & Controller

Get the financial leadership of a full-time CFO (Chief Financial Officer) without the full-time cost. We'll build cash flow forecasts tied to your project timelines and give you job-level profitability dashboards.

🌎

Multi-State Tax Compliance

Grow into new states without walking into a compliance problem. We'll run the nexus analysis the moment you take on out-of-state work. Then we register and file wherever you need to. New obligations get flagged before they turn into a notice from a state you didn't know you owed.

How It Works

Stabilize, Strategize, Scale

01

Discovery Call

We start by learning your project model, billing structure, equipment fleet, and geographic footprint. We'll tell you plainly what's missing and what it takes to get real job-level visibility. Thirty minutes, free, no pressure.

02

Stabilize

Once we know where things stand, we clean up your books and build or refine your job costing structure. From there, we set up revenue recognition that matches how you actually bill. We also reconcile work-in-progress against billing and close any state compliance gaps we find. Along the way, we review prior returns for depreciation and deductions you may have missed.

03

Strategize

With clean, accurate data in place, we build your tax strategy around it. That covers equipment depreciation planning, entity structure, state tax minimization, and contractor classification documentation. All of it ties to where your project pipeline is actually headed.

04

Scale

From there, you get job-level profitability dashboards and cash flow forecasting built around your project timelines. Equipment replacement planning, bonding documentation, and a CFO-level voice in the room for bid/no-bid decisions all come standard. That scales with you from a single market through multi-state growth.

Frequently Asked Questions

Common Questions

What types of field service companies do you work with?

We work with mechanical, electrical, and environmental services contractors, plus civil engineering firms, HVAC and plumbing companies, and facility maintenance operators. That covers project-based businesses at every stage, from single-market operators to multi-state companies managing hundreds of concurrent projects.

Can you help with equipment depreciation and Section 179?

Yes. We evaluate each equipment acquisition, whether vehicles, tools, machinery, or technology, and weigh Section 179 expensing against bonus and standard depreciation. The right strategy depends on your income, cash flow, and long-term tax position. That’s because one mistake we see often is applying the same approach to every asset instead of tailoring it.

Do you handle project-based revenue recognition?

Yes. Milestone billing, time-and-materials, fixed-fee, and percentage-of-completion contracts each require different revenue recognition. We map your billing model to track work-in-progress so your financials reflect project performance, not just cash received.

How do you support multi-state compliance for field service companies?

New project sites and subcontractor networks that cross state lines can create tax exposure. Therefore, we monitor and flag new obligations as your footprint expands. This includes nexus analysis, tax registration, and filing for multi-state ensure compliance.

Can you help with contractor vs. employee classification for service companies?

Yes. Field service companies often mix subcontractors with W-2 crews, and classification rules vary by state and project type. That’s why we evaluate your workforce against IRS guidelines and make sure your 1099 reporting is correct.
