Carrie Anderson
Co-Founder & Principal Analyst
• BP — Global Financial Forecasting
• Former Corporate Controller
• Active Commercial Loan Analyst — Montana Community Bank
• 300+ Commercial Loans Analyzed & Packaged
• FDIC Examination Support
• Work reviewed by KPMG & Wipfli
• Family background in business acquisition & turnaround
Carrie Anderson's career is defined by financial models that hold up under the most demanding scrutiny. At BP, Carrie was recognized for forecast accuracy across global teams, including partners in Singapore and Budapest. She served as a Controller for a major corporation before co-founding 406 Consulting Group, building financial infrastructure that scaled with complex, multi-entity operations.
When a regional bank needed help with its quarterly call report, Carrie rebuilt the model from scratch — reducing a 40-hour quarterly process to a few hours. The report drew sustained regulatory scrutiny over two years and held up through that review, reinforcing its accuracy and structure.
For over 10 years, Carrie has served as a contracted commercial loan analyst for a Montana community bank — spreading financials, building loan packages, and providing recommendations the bank president relies on. She has analyzed and packaged 300+ commercial loans, and she supports the bank through FDIC examinations and regulatory reviews. When she helps a client prepare for a commercial loan, she brings the lender's perspective to the table. The same analysis she applies to your loan package is the analysis lenders use to approve or deny it.
Her work has held up in review environments involving firms such as KPMG and Wipfli. She brings that same standard of rigor to every 406 client — financial modeling, reporting architecture, and analytical depth that most firms simply can't match. Her favorite saying: “If you can think it, I can build it.”
Before her corporate career, Carrie grew up in a family that built and operated commercial businesses — gas stations, retail properties, and other ventures across the region. Her family's model was to acquire underperforming businesses, fix the operations and financials, and sell them at a profit. She was part of that process from a young age. That background gives her an instinct for operational reality that most financial analysts never develop — she doesn't just build models, she understands the businesses behind them.
Jason Anderson
Co-Founder & Principal Advisor
• BP — Lead Operator & Accounting Manager
• Uncovered $75M+ in unbilled inventory at BP
• Managed ~1M barrels/5 days on Colonial Pipeline
• System replicated by Accenture — still in use 25+ years later
• Consulted by local banks for tax analysis
• Architect of custom financial tools for trucking and craft beverage clients
• B.S. Accounting · 10+ years tax preparation
Prior to founding 406 Consulting Group, Jason spent a decade at BP in progressively senior operational and analytical roles. He began as an inventory analyst — and within that role uncovered more than $75 million in unbilled inventory, money BP didn't know it was owed. He built the reconciliation system that recovered it, an Excel-based tool that was later rebuilt as a web application and remains in use more than 25 years later.
From there, Jason moved into oil operations, scheduling petroleum on Colonial Pipeline for BP — managing inventory across a multi-state corridor from Pasadena, Texas to Linden, New Jersey, and shipping nearly one million barrels every five days. He optimized inventory positions across contango and backwardation markets, and eventually moved to the fuel oil trading bench, managing operations out of New York Harbor, Panama, Houston, and Louisiana offshore. In multiple operating roles, Jason helped improve throughput and execution in environments where mistakes carried immediate financial consequences.
What made Jason's BP career distinctive wasn't just the scale — it was the operational complexity he had to manage across it. He coordinated with multiple contractors and counterparties across industries, planned and scheduled the movement of ships and barges, ensured compliance with federal and state regulations, managed deals and held the firm to contract performance, worked directly with sales and trading teams, and reported to BP executives.
Jason holds a degree in accounting and brings more than 10 years of tax preparation experience to the firm. That operational intelligence — the ability to find what others miss, build tools others don't think to build, and see the path to profitability that wasn't visible before — is what he brings to every client engagement at 406.

The G.R.O.W.T.H. Framework
Our mission is to empower businesses to reach their fullest potential through six core principles
Grounded in Your Numbers
We don't give generic advice. Every recommendation starts with your actual books — your margins, your cash cycle, your payroll structure. A Montana contractor we work with discovered he was losing 11% gross margin on his largest jobs because his job costing wasn't capturing change orders. That's the kind of insight that changes decisions.
Real-Time Visibility
Most business owners find out how last month went when their accountant files the return. Our clients see it in a dashboard. When a Flathead Valley hospitality client needed a line of credit in 30 days, we had 12 months of clean, lender-ready financials ready to submit. They got approved.
Ownership-Ready Financials
When you're ready to sell, raise capital, or bring on a partner, your books tell the story. We've helped clients clean up years of commingled expenses, restructure entity ownership, and produce the financial narrative that makes a transaction possible — not just a tax return that checks a box.
Work Built Before AI Existed
The operating systems we built for clients in trucking, distilling, and construction — revenue-per-mile dashboards, batch cost tracking, rate negotiation calculators — were built by hand, from deep industry knowledge. That methodology doesn't change. The tools we use to build it faster now do.
Transparent Pricing, No Surprises
We tell you what things cost before we start. Our engagements are scoped, priced, and documented. If scope changes, we tell you. No surprise invoices at year-end, no billing for every email. Clients who've worked with large firms tell us this alone is worth the switch.
Held Accountable to Results
We don't disappear after onboarding. Monthly calls, quarterly reviews, and annual strategy sessions are built into every engagement above bookkeeping. If your cash flow forecast was off by more than 10%, we want to know why — and we'll tell you before you ask.
Each principle builds on the last — creating a comprehensive framework that transforms financial chaos into scalable, strategic control.

Why We're Different — In Detail
The BP trading desk, Carrie's family business background, the specific proof points, and the philosophy that separates 406 from every other firm. It's all on one page.
Exit & Transition Readiness
Built to Run Without You.
Valued for What It's Worth.
Carrie grew up in a family that acquired underperforming businesses, fixed their operations and financials, and sold them at a profit. That background shapes how 406 approaches every engagement — we build financial infrastructure that makes a business more valuable, not just more compliant.
Whether you're 2 years or 10 years from an exit, the work you do today determines what your business is worth when you're ready to sell, transition, or step back. Clean books, documented systems, and a business that runs without you in every meeting are the three things that move valuation multiples.
The Cost of Not Being Ready
Businesses that are not exit-ready often pay for it through lower offers, higher perceived risk, and avoidable tax leakage.
Messy books
Buyers perceive higher risk and adjust offers accordingly
Owner dependency
Reduces perceived business value and transferability
Wrong entity structure
Can result in avoidable tax leakage on proceeds
No documented systems
Extends due diligence and increases deal risk
We start building exit-ready infrastructure from day one — not six months before you want to sell.
