Bookkeeping for South Boston Small Businesses

Bookkeeping, payroll, and financial advisory for South Boston businesses. From Broadway to the Seaport, we handle the numbers.

Bookkeeping for South Boston

South Boston has changed dramatically, but it hasn’t become one thing. Walk down Broadway and you’ll still find businesses that have been there for decades. Head toward the Seaport and you’re in a different world entirely. Tech companies, biotech firms, new restaurants opening every month. Both sides of the neighborhood need bookkeeping. Neither needs to pay downtown Boston rates for it.

We’re based in Andover and serve businesses throughout Greater Boston, including South Boston. Monthly bookkeeping, payroll, catch-up work when things have fallen behind, and financial advisory for companies that have outgrown basic books. The back-office support you need without adding headcount.

Monthly Bookkeeping

Transactions categorized, accounts reconciled, books closed every month. Financial statements that tell you where you stand so you’re not guessing at profitability.

Payroll

We process payroll, handle tax deposits and filings, and issue W-2s. Massachusetts compliance handled. Your employees get paid correctly and on time without you tracking deadlines.

Catch-Up Bookkeeping

Months behind? Years? We reconstruct the history, clean up the mess, and deliver books you can actually use. Most clients start exactly there.

Financial Advisory

For growing companies that need more than bookkeeping. Cash flow forecasting, budget development, KPI tracking. CFO-level thinking without a CFO salary.

South Boston Businesses We Work With

The Seaport gets the attention, but South Boston’s economy is broader than the Innovation District. There are restaurants and bars throughout the neighborhood. Professional service firms in the newer buildings. Contractors working on the endless construction. Longtime local businesses that have adapted as the neighborhood changed around them.

We work with businesses doing anywhere from a few hundred thousand to several million in revenue. Big enough to need professional bookkeeping, not quite big enough to justify a full-time accounting hire. That’s where Andover, MA advisory services like ours make sense.

Tech and Startups

The Seaport has become a hub for tech companies and venture-backed startups. We handle the accounting basics while providing the financial reporting and forecasting that founders and investors need to see.

Restaurants and Bars

From the old pubs on Broadway to the new spots near the waterfront, South Boston runs on hospitality. We track food cost, labor, tips, and daily sales so you know if the numbers actually work.

Professional Services

Consultants, agencies, law firms, and other professional practices. If you’re billing clients and losing track of expenses, we organize the books so you see what you’re actually keeping.

Healthcare Practices

Medical offices, dental practices, therapy providers serving the neighborhood. We manage the timing difference between delivering services and collecting payment, keeping cash flow visible.

Common Questions

You're based in Andover. Why would a South Boston business work with you?

We serve the entire Greater Boston area. Most bookkeeping happens digitally anyway. We're available when you need us, and the distance means you're not paying for downtown Boston overhead.

Do you work with startups in the Seaport?

Yes. Early-stage companies often need fractional CFO support more than basic bookkeeping. We provide financial strategy, forecasting, and investor-ready reporting for growing businesses.

What does monthly bookkeeping cost?

Pricing depends on transaction volume and complexity. We provide flat monthly rates after understanding your business so there are no surprises.

Can you help with books that are behind?

That's a common starting point. We do catch-up work to get you current, then transition to monthly service to keep it that way.

Do you handle payroll for Massachusetts businesses?

Yes. Full payroll processing including tax deposits, quarterly filings, W-2s, and Massachusetts-specific compliance. You approve hours, we handle everything else.
