These are the situations we see most often with New Hampshire businesses — and what changes when the financial foundation is built right.
When the Bank Says No — And the Books Are Why
What This Unlocks
Clean financials unlock things that messy books never can: a readable P&L that shows true profitability, a balance sheet that supports a credit application, and a business that looks like what it actually is. The work is the same. The financial picture is completely different.
Here is a situation we see regularly with small contractors along the Seacoast and in the Manchester corridor. A landscaping company at $220K in revenue — profitable, busy, and growing. The owner has been in business for three years. He needs a $45K line of credit to cover equipment and payroll through the winter. The bank says no.
The Problem
The reason is not the business. The business is doing fine. The reason is the books. Personal and business expenses are mixed. The P&L shows uneven revenue because some deposits were coded as owner contributions and some were not. There is no clear picture of what the business actually earns. From a lender's perspective, it looks like a hobby, not a company.
The Books Looked Fine. They Weren't.
What This Unlocks
A cheaper bookkeeper records what happens. A good one understands what it means — and knows the difference between a capital contribution and revenue, between an asset purchase and an expense. That distinction alone was worth more than several years of bookkeeping fees.
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 categorized, and the reports were delivered on time. The owner had no reason to think anything was wrong.
The Problem
When we reviewed the books in detail, we found two significant problems. First, owner capital contributions had been coded as revenue — which inflated taxable income and meant the owner had been paying income tax on money that was already his own. Second, major equipment purchases had been coded as owner contributions rather than fixed assets. That meant no depreciation schedule, no Section 179 deduction, and thousands of dollars in legitimate write-offs that simply never happened. The owner was preparing to write a check to the IRS for taxes he did not actually owe. He did not have to.
From $350K to $1.8M — Without the Owner Doing Everything
What This Unlocks
What the path to $1.8M looks like when the financial systems keep pace: margin by client and service type, a monthly P&L the owner can actually read, and controller-level oversight that lets him delegate with confidence. By year three, the owner is not managing every ticket — he is managing the business.
Here is what an IT managed services company in the Nashua corridor often looks like at $350K in revenue. The owner is handling every client relationship, every service call, and every invoice. The business is profitable — but only because he is working 55-hour weeks. He cannot take time off. He does not know which clients are actually profitable.
The Problem
The financial system at $350K is usually the same one that worked at $100K: a bank account, a credit card, and a bookkeeper who reconciles once a month. That system does not tell you your margin by client or service type. It does not tell you that your managed services contracts are running 44% margin while your break-fix work is running 12%. It does not give you the data to hire a service manager and trust him with the numbers.
When the Offer Comes, You Have 3 Weeks or 9 Months
What This Unlocks
Businesses that are built with controller-level financial systems from the start are acquisition-ready before the call ever comes. The books are clean. The EBITDA is defensible. The story is clear. That is not luck — it is what good financial infrastructure makes possible.
New Hampshire's I-93 corridor from Manchester to Portsmouth is seeing real M&A activity in professional services, IT, and specialty trades. PE-backed rollups and strategic buyers are actively looking at businesses in the $1M-$10M revenue range. When the call comes, they move fast.
The Problem
Most small business owners are not ready. Not because the business is not valuable — it is. But because the books were built for tax compliance, not for a buyer's due diligence process. A buyer needs 3 years of clean, auditable financials, an adjusted EBITDA calculation with documented add-backs, and a chart of accounts that makes sense to someone who has never worked in your business. When that is not in place, due diligence that should take 3 weeks takes 9 months — and deals fall apart in the gap.

Common Questions
New Hampshire Business Owner FAQs
NH has no income tax. Why do I still have a big state tax bill?
New Hampshire has no tax on wages or salary, but it does have the Business Profits Tax (BPT) at 7.5% on net business income and the Business Enterprise Tax (BET) at 0.5% on enterprise value. For profitable businesses, these add up quickly — and most owners are not planning around them.
I work in Massachusetts but live in New Hampshire. How does that affect my taxes?
This is one of the most common situations we see in southern NH. MA taxes income earned in MA regardless of where you live. If you are a W-2 employee working in MA, your employer withholds MA taxes. If you are a business owner with MA clients, you may have MA nexus. We help you understand the exposure and structure it correctly.
What is the BPT apportionment formula and does it apply to my business?
NH uses a single-sales-factor apportionment formula for the BPT. If you have sales in multiple states, only the NH-sourced portion is subject to BPT. Many NH businesses with out-of-state customers are over-apportioning to NH and overpaying. We review the apportionment calculation as part of our tax planning work.
What does a Controller engagement cost for a NH business?
Controller services typically run $1,500-$4,500/month depending on complexity, transaction volume, and whether you need multi-entity or multi-state work. We scope it after a discovery call.
We are a contractor in the Seacoast area. Do you do job costing?
Yes — job costing for contractors is one of our core services. We set up the chart of accounts, the cost codes, and the reporting so you know your margin on every project before the final invoice goes out.
