What is the difference between bookkeeping, a controller, and a fractional CFO?
Bookkeeping is the foundation. A bookkeeper records your transactions, categorizes them correctly, reconciles your bank and credit card accounts, and produces monthly financial statements. The work is about capturing what happened in your business so you have accurate numbers to look at. For most owner-operated service businesses, this is where you start, and for many, this is all they need.
A controller adds oversight and rigor. If your business has grown to the point where volume and complexity have increased, or if you have someone doing books in-house and want a second set of eyes, a controller reviews the work, catches errors before they compound, and tightens the monthly close. Think of it as adding a layer of accounting expertise above the day-to-day bookkeeping. This role is about accuracy at scale. A controller makes sure the books are not just done but done correctly.
A fractional CFO looks forward instead of backward. Where bookkeeping captures what happened and a controller ensures accuracy, a CFO focuses on what comes next. Cash flow forecasting, budgeting, pricing analysis, growth planning, and strategic decisions about where to put your money. This is the level where you get financial leadership without hiring a full-time executive. A fractional CFO is for businesses that have outgrown basic bookkeeping and need someone who can help make the big calls.
How do you know which level you need? If you just need clean books and accurate monthly reports, bookkeeping fits. If your business has gotten complicated enough that you worry about whether the numbers are actually right, controller oversight adds that layer of review. If you find yourself making financial decisions by gut because you don’t have the data or analysis to guide you, a fractional CFO gives you the forward-looking insight you’re missing.

More Questions
I sell both services and products. How do I handle sales tax?
In Massachusetts, most services aren't taxable but physical products are. If you sell both, you need to charge 6.25 percent sales tax on the products while leaving the services untaxed, and track them separately in your books.
Read answerHow do I keep clean books for a contract-based facility business?
Clean books for a contract-based facility business start with tracking each contract as a separate customer in your accounting system. This lets you see revenue by contract, run payroll accurately for your staff, and close the books cleanly each month with statements that show you how the business is really doing.
Read answerHow do I write off my truck and equipment as a landscaper or contractor?
Section 179 expensing and 100 percent bonus depreciation let you deduct the full cost of qualifying equipment and vehicles in the year you buy them. For trucks, you also choose between actual expenses and the standard mileage rate, which is 72.5 cents per mile for 2026. Clean records of purchases and mileage make the deductions hold up.
Read answerHow do you keep my financial information secure?
We use QuickBooks Online with bank-level encryption, share documents through a secure portal rather than email attachments, and limit access to your data. Working with a small firm means fewer people touch your information.
Read answerShould I elect S-corp status as a solo consultant, and at what income does it pay off?
It typically pays off around $60,000 to $80,000 of net profit. At that level, splitting income between a reasonable salary and distributions can save you several thousand dollars a year in self-employment tax, with savings growing as income increases.
Read answerDo you file my business's tax return?
It depends on your business structure. For sole proprietors and single-member LLCs, we prepare your personal return including the Schedule C that reports business income. For S-corps, partnerships, and C-corps, we keep tax-ready books and handle your personal return, but the entity return itself needs a separate preparer.
