Bookkeeping & Accounting for Boston Small Businesses

Monthly bookkeeping and payroll for Boston businesses. Andover-based with deep Greater Boston roots. Flat monthly rates, real expertise.

Bookkeeping for Boston Businesses

We’re based in Andover, about 25 miles north of Boston. Close enough to know the city, far enough to keep our overhead reasonable and pass those savings along. We provide small business bookkeeping services for companies throughout Boston and the surrounding area. Monthly closes, clean financials, payroll, and the back-office support that lets you focus on running your business.

Boston has no shortage of accounting firms. What’s harder to find is a bookkeeper who combines hands-on detail work with the strategic perspective that growing businesses need. We’ve scaled with high-growth companies and know what clean books look like when investors or lenders start asking questions.

Monthly Bookkeeping

Transactions categorized, accounts reconciled, books closed every month. You get accurate P&L and balance sheet reports without spending your weekends catching up on QuickBooks.

Catch-Up Work

Books behind? We clean up months or years of backlog, reconstruct what’s missing, and get you current. Most Boston clients start here before moving to ongoing monthly service.

Payroll

Full payroll processing including Massachusetts state requirements, tax deposits, quarterly filings, and year-end W-2s. Multi-state payroll handled if you have remote employees or contractors elsewhere.

Financial Strategy

Fractional CFO services for businesses ready for more than basic bookkeeping. Cash flow forecasting, budgets, KPI tracking, and strategic guidance when you need someone who can see the bigger picture.

Boston Industries We Work With

Boston’s economy runs on everything from biotech startups in Kendall Square to restaurants in the North End to professional services firms in the Financial District. The businesses are different, but the need is the same. Accurate books, filed on time, with someone who understands what the numbers mean.

We work with businesses that have outgrown doing it themselves but aren’t ready to hire a full-time bookkeeper. If you’re spending too much time on financial admin or just avoiding it altogether, we’re set up to fill that gap.

Tech Startups

SaaS companies and tech startups building in Boston and Cambridge. Investor-ready financials, burn rate tracking, and books that hold up during due diligence.

Healthcare Practices

Medical offices, dental practices, therapy providers, and specialty clinics throughout Greater Boston. We handle the revenue recognition and receivables tracking that healthcare accounting requires.

Professional Services

Consulting firms, marketing agencies, law offices, and other professional practices. Clean overhead tracking, project profitability, and financials organized for partner review.

Restaurants and Hospitality

Boston’s food scene keeps growing. We track food costs, labor percentages, tip reporting, and the daily sales data that restaurants need to know if they’re actually making money.

Common Questions

Where is your office located?

We're based in Andover, just north of Boston. We serve businesses throughout Boston and the Greater Boston area. Most of our work happens remotely, but we're close enough for in-person meetings when it makes sense.

What does monthly bookkeeping cost?

Starting at $199 per month based on your transaction volume. We quote flat rates so you know exactly what you're paying. No hourly billing that creeps up unexpectedly.

Do you handle Massachusetts payroll requirements?

Yes. We manage all Massachusetts-specific payroll requirements including state tax withholdings, paid family leave, and quarterly filings. If you have employees in multiple states, we handle that too.

Can you work with my CPA at tax time?

Absolutely. We prepare your books specifically for a clean handoff. Your CPA gets organized financials and supporting documentation. No scrambling in March.

What if my books are months behind?

That's a common starting point. We do catch-up work to get your records current, then move into ongoing monthly service. Most clients come to us with some backlog to clean up.
