How We Help

Real Situations.
Real Outcomes.

Every service we offer is built around a problem Montana business owners actually face. Here's what that looks like in practice — and what becomes possible when the financial foundation is right.

The Scenario

When the Bank Says No — And the Books Are Why

Picture a general contractor out of Bozeman. Three crews, about $400,000 in revenue, busy enough that the owner is on job sites six days a week. He goes to First Interstate for a $75,000 equipment line to buy a skid steer and a trailer. The bank says no. Not because the business isn't making money — it probably is. But the books are a mess. Business expenses are mixed with personal spending. There's no job costing. The P&L looks like a disaster even though cash is coming in. This is one of the most common situations we see with contractors across the Gallatin Valley and Flathead.

What This Unlocks

When books are mixed with personal spending, a bank can't evaluate the business — so they don't approve it. Clean financials unlock things that messy books never can: a readable P&L that shows true profitability by job, a balance sheet that supports a credit application, and a clear picture of what the business actually earns. A Bozeman contractor at $400K with proper job costing and clean separation between business and personal is a fundable business. The same contractor with mixed books isn't — regardless of how busy the crews are.

Bookkeeping Review

The Books Looked Fine. They Weren't.

A client came to us after working with a cheaper bookkeeping service for several years. On the surface, the books looked okay — revenue was being recorded, expenses were being tracked. But when we reviewed the books in detail, we found two problems that had been compounding quietly for years. First: the owner had been making capital contributions to the business — putting their own money in to cover slow months — and those contributions had been coded as revenue. That inflated taxable income every single year. The owner was paying income tax on money they had already paid tax on personally. Second: equipment purchases — a skid steer, a trailer, a work truck — had been coded as owner contributions instead of fixed assets. That meant the business never took the depreciation deductions it was entitled to. Thousands of dollars in write-offs, gone.

When we corrected the coding and reconstructed the proper treatment of those transactions, the picture changed significantly. The owner had been overpaying taxes for years because the books were wrong in ways that aren't obvious unless you know what to look for. A cheaper bookkeeper records what happens. A good one understands what it means — and catches the difference between a capital contribution and revenue, between an asset purchase and an expense. The owner was prepared to keep paying. They didn't have to.

The books looked fine. But they were paying taxes on money they'd already paid tax on — for years.

The Growth Path

From $600K to $3M — Without the Owner Having to Be There Every Day

Here's what a Missoula hospitality business at $600,000 in revenue typically looks like: the owner is managing everything — scheduling staff, handling vendor relationships, covering shifts when someone calls out, and trying to keep up with the books on Sunday nights. She knows she's leaving money on the table but doesn't know where. She can't take a vacation. She can't hire a manager because she doesn't know if she can afford one. She is the bottleneck in her own business. This is the most common pattern we see in Montana service businesses that are growing but haven't built the financial systems to support the growth.

The path from $600K to $3M isn't about working harder — it's about building the financial infrastructure that lets the business run without the owner being the answer to every question. That starts with a real P&L that shows which revenue streams are actually profitable. Then a simple dashboard: revenue by category, labor cost as a percentage of revenue, a 13-week cash flow forecast. With that foundation, an owner can make a decision like 'stop discounting the slow season and focus on events and private dining' — because the numbers show event margins at 38% and discounted walk-in at 9%. That's the kind of insight that changes a business.

Acquisition Readiness

When the Offer Comes, You Have 3 Weeks or 9 Months

Here's what acquisition readiness actually looks like in practice. A Kalispell HVAC and mechanical company — 12 technicians, $4.2M in revenue, eight years of steady growth in the Flathead Valley — gets contacted by a regional PE-backed rollup that's been acquiring mechanical contractors across the Mountain West. The owner wasn't actively looking to sell. But the offer was real, and the number was interesting. What happens next depends entirely on one thing: whether the books are already right.

If the financials are clean, auditable, and consistently maintained — three years of management reporting, proper job costing, clean separation of revenue streams — due diligence takes three weeks. If they're not, it takes six to nine months to reconstruct, and half the time the deal falls apart in the process. The difference isn't luck. It's whether the financial foundation was built before the opportunity arrived. This is why Controller-level work matters even when you're not thinking about selling. The business that's ready when the offer comes is the business that built the systems years before anyone called.

Why 406 Consulting Group

We're Not a National Firm.
We're From Here.

406 Consulting Group was built in Montana. Our founder understands the seasonal rhythms, the community bank relationships, and the specific financial challenges that come with running a business in a state where the economy is tied to construction, agriculture, hospitality, and natural resources.

She also spent years in Montana commercial banking — reviewing financials, structuring SBA loans, and evaluating business credit at institutions like Glacier Bank, First Interstate, and Stockman Bank. When you need a line of credit, she knows exactly how to present your books to get approved.

PTET Election Evaluated for Every Eligible Client

Most Montana S-Corp and partnership owners are leaving federal tax savings on the table. We evaluate the pass-through entity tax election for every eligible client as part of onboarding — it's one of the most valuable tools available and most owners have never heard of it.

Seasonal Cash Flow Built Into Our Process

We don't treat Montana's seasonal economy as an exception. 13-week rolling cash flow forecasts are standard for every client — so the summer peak and winter slowdown are planned for, not reacted to.

Lender-Ready Financials, Not Just Tax-Ready

Getting approved for credit is often the difference between growth and stagnation. We prepare your books to pass underwriting review at Montana community banks — because we know exactly what they need to see.

Built for the $1M–$50M+ Montana Business

We're not the right fit for a solo freelancer or a Fortune 500 subsidiary. We're built for the owner-operated Montana business that has outgrown its current financial setup and needs real infrastructure.

Montana Tax Environment

What Montana's Tax Structure Means for Your Business

Montana's tax environment is genuinely different from most states — no sales tax, a two-bracket income tax, and a pass-through entity election that most business owners have never heard of.

01

No General Sales Tax

Structural Advantage

Montana is one of only five states with no general sales tax. For retail, hospitality, and service businesses, this simplifies operations — but it also means the state leans harder on income tax, making entity structure and owner compensation decisions more consequential.

02

Pass-Through Entity Tax (PTET) Election — 5.9%

Most Underutilized

Montana's PTET election allows S-Corps and partnerships to pay state income tax at the entity level, making it fully deductible as a business expense. This effectively bypasses the federal $10,000 SALT cap. For a business owner with $200K in Montana pass-through income, this election can save $2,600–$4,400 in federal taxes annually. Most Montana business owners are not using it.

03

Income Tax: 4.7% and 5.9% Graduated Rates

Planning Required

Montana uses a two-bracket graduated income tax. The 5.9% top rate applies to most profitable small business owners. For an owner drawing $200K in pass-through income, that's $11,800 in state income tax — real money that requires a strategy, not just a filing.

04

Capital Gains: 3.0% Preferential Rate

Exit Planning

Montana taxes long-term capital gains at 3.0% on the first $21,100 above ordinary income. For business owners planning an exit or asset sale, this creates meaningful planning opportunities around timing and structure that most accountants don't address proactively.

Where We Work

Montana Regions We Serve

Montana's economy isn't uniform. Billings is not Bozeman is not Missoula. Each market has its own industries, challenges, and financial dynamics.

Billings

Eastern Montana

Montana's largest city and economic hub of the Upper Plains. Contractors, trucking operators, and healthcare-adjacent businesses here are often doing $3M–$15M in revenue with bookkeeping that hasn't kept pace with their growth.

Construction & GCTrucking & LogisticsHealthcare-AdjacentEnergy Services

Bozeman

Southwest Montana

One of the fastest-growing cities in the country. Bozeman businesses face extreme labor competition, commercial rents that have tripled in a decade, and the financial complexity that comes when revenue growth outpaces systems.

Tech & SaaSHospitality & TourismConstructionProfessional Services

Missoula

Western Montana

A university town with strong, stable revenue across trades, healthcare, retail, and nonprofits — but often underdeveloped financial infrastructure. Nonprofits here face unique reporting and compliance requirements.

Trades & Specialty ContractorsHealthcare-AdjacentNonprofitsRetail & E-Commerce

Construction, hospitality, and trades businesses scaling fast in one of Montana's fastest-growing markets. Glacier National Park drives tourism revenue heavily concentrated in a 90-day window — seasonal cash flow planning is essential.

Construction & RemodelingHospitality & LodgingLandscaping & TradesReal Estate

Great Falls

Central Montana

A working-class city with a strong manufacturing, trades, and agricultural services base. Stable revenue, but financial inefficiencies that compound over time when there's no one watching the numbers closely.

Manufacturing & IndustrialTrades & ContractorsAgriculture-AdjacentRetail

Helena

Southwest Montana

Montana's capital has a professional services economy shaped by state government, healthcare, and law. Complex entity structures, government contracting compliance, and partner compensation that require more than basic bookkeeping.

Day-to-Day Financial Operations

The Foundation Has to Be Right Before Strategy Matters

Most Montana businesses have a tax preparer. Very few have clean books, compliant payroll, and real-time financial visibility. That's the foundation we build first — because without it, every other service is built on sand.

Bookkeeping

Clean Books, Every Month

Montana businesses — construction, hospitality, agriculture, professional services — all need accurate, reconciled financials maintained monthly, not just at tax time. We use QuickBooks Online or Xero, categorized correctly for your industry, and ready for your bank, your CPA, or your partners whenever they need it.

Payroll

Montana Payroll Done Right

Montana's seasonal economy — construction, hospitality, agriculture, and tourism — creates real payroll complexity: variable hours, seasonal hires, tipped employees, and multi-entity owners. We process payroll accurately and on time, handle Montana unemployment insurance filings, and make sure your setup is correct before it becomes a liability.

Financial Leadership

Montana Businesses Need More Than a Bookkeeper.They Need a Controller.

Most Montana businesses between $1M and $15M are running on bookkeeper-level infrastructure — no month-end close, no cash flow forecasting, no financial reporting a bank would take seriously. When the opportunity arrives, the books aren't ready.

Our Controller and fractional CFO services give you executive-level financial leadership without the $200K+ salary. Month-end close, management reporting, 13-week cash flow forecasting, and a strategic partner who knows Montana's tax environment inside out.

01

Month-End Close

Accurate, timely financials every month — not just at tax time.

02

13-Week Cash Flow Forecast

Seasonal gaps visible months ahead so you can plan, not react.

03

Management Reporting

P&L, balance sheet, and KPI dashboards built for decisions.

04

Lender & Investor Ready

Books at the standard banks and investors require — before you need them.
