Bookkeeping & Accounting for Cambridge Businesses

Bookkeeping and accounting for Cambridge businesses. From Kendall Square startups to Harvard Square shops, clean books and strategic financial support.

Bookkeeping for Cambridge Businesses

Cambridge runs on innovation. From the biotech labs around Kendall Square to the restaurants lining Mass Ave, businesses here move quickly. That pace creates complexity in the books. Revenue recognition for SaaS contracts, R&D expense tracking, multi-state payroll for distributed teams. We handle that complexity so you can focus on building.

We’re an Andover, MA bookkeeper that works with businesses across Cambridge and Greater Boston. Monthly bookkeeping, catch-up work, payroll, and financial strategy. The back-office support you need without adding headcount.

Monthly Bookkeeping

Transaction categorization, bank reconciliation, and monthly close. Your books stay current every month with accurate P&L and balance sheet reports delivered on schedule.

Catch-Up Bookkeeping

Books that haven’t been touched since your seed round? We clean up the backlog, reconcile everything, and get your records current. Most Cambridge startups we work with started here.

Managed Payroll

Full payroll processing including tax deposits, quarterly filings, and year-end W-2s. Your team gets paid correctly and on time. Multi-state payroll handled for companies with remote employees.

Financial Strategy

Fractional CFO support for companies that need more than bookkeeping. Cash flow forecasting, budget development, and investor-ready financials when you’re preparing to raise.

Cambridge Industries We Serve

Cambridge has one of the most diverse business ecosystems in Massachusetts. Venture-backed startups share blocks with law firms that have been here for decades. Restaurants in Harvard Square serve students and professors. Healthcare practices support the research community. Each type of business has different books, but they all need the same thing: accurate numbers and someone who understands their situation.

We work with Cambridge businesses doing anywhere from early-stage revenue to several million annually. If you’ve outgrown doing the books yourself but aren’t ready for a full-time accounting hire, that’s the gap we fill.

Tech Startups and SaaS

Tech companies around Kendall Square and the Cambridge Innovation Center. We handle subscription revenue recognition, burn rate tracking, and books that are ready when investors start asking questions.

Professional Services

Law firms, consulting practices, marketing agencies, and architecture firms. We track billable hours, manage project profitability, and keep overhead reporting clean for partner review.

Restaurants and Cafés

Harvard Square, Central Square, Inman Square. High transaction volume, tip reporting, food cost tracking. We handle the financial complexity that comes with running a restaurant in Cambridge.

Healthcare Practices

Medical offices, dental practices, and therapy providers serving the Cambridge community. Insurance receivables, patient balances, and the revenue recognition timing that makes healthcare accounting its own discipline.

Common Questions

Do you work with businesses in Cambridge?

Yes. We work with businesses throughout Cambridge including Kendall Square, Harvard Square, Central Square, and Porter Square. Our office is in Andover, and we work remotely with all clients across the Greater Boston area.

What does monthly bookkeeping cost?

Monthly bookkeeping starts at $199. Your rate depends on transaction volume and complexity. We provide a flat monthly quote after reviewing your business so there are no surprises.

Can you help if my company is growing fast?

That's exactly when bookkeeping matters most. We help growing companies maintain clean books, prepare for investor due diligence, and provide financial strategy support when you need more than just transaction tracking.

Do I need to meet in person?

Not required. We handle everything remotely through secure document sharing and regular communication. Most Cambridge clients prefer this approach since it fits their schedules better.

What if my books are behind?

We do catch-up work regularly. Whether you're a few months behind or haven't touched your books since launch, we clean everything up and get you current before moving to monthly service.
