Bookkeeping & Advisory for Back Bay Businesses

Bookkeeping and advisory services for Back Bay businesses. Clean financials for professional services firms, retailers, and restaurants in Boston's premier district.

Bookkeeping for Back Bay

Back Bay businesses already pay premium rents on Boylston and Newbury. Adding a downtown Boston accounting firm on top of that overhead doesn’t always make sense. We provide Andover, MA advisory services to businesses throughout Back Bay, delivering the same quality with lower overhead. Everything runs remotely, which means responsive service without the commute or the cost.

Our clients in the neighborhood include consulting firms near Copley, restaurants on Newbury Street, and professional services offices along Commonwealth Ave. Different businesses with the same need for accurate books and timely financial information.

Ongoing Bookkeeping

Transaction categorization, bank reconciliation, and monthly close delivered consistently. Your P&L and balance sheet arrive every month so you know where the business stands without spending your evenings in QuickBooks.

Payroll Processing

Full payroll service with direct deposits, tax filings, and quarterly reports. Massachusetts withholding, unemployment insurance, and year-end W-2s handled. Your team gets paid correctly and on time.

Financial Strategy

CFO-level guidance without the full-time salary. Cash flow forecasting, budget development, and strategic planning for Back Bay businesses ready to grow beyond their current stage.

Multi-State Compliance

Remote teams and out-of-state clients create tax obligations beyond Massachusetts. We handle multi-state payroll registration, sales tax nexus questions, and the compliance work that comes with growth.

Back Bay Businesses We Work With

Back Bay attracts businesses that value a prestigious address. Consulting firms, financial advisors, and agencies choose the neighborhood for client accessibility and the credibility that comes with a Boylston Street office. These same businesses need financials that match their professional image.

We work with Back Bay businesses doing roughly $100K to several million in revenue. Established enough to need real accounting support. Not so large that a full-time controller makes sense yet.

Professional Services

Consulting firms, marketing agencies, architecture practices, and other professional services in the Back Bay corridor. We track profitability by client and project so you know which work actually makes money.

Financial Services

RIAs, wealth managers, and financial advisors with offices near Copley. Clean books matter for regulatory compliance and client trust. We handle the accounting so you can focus on managing client portfolios.

Restaurants and Hospitality

Newbury Street restaurants, cafés, and bars operating on tight margins. High transaction volume, tip reporting, and food cost tracking handled accurately so you understand what each week actually produced.

Healthcare Practices

Medical offices, dental practices, and therapy providers in the neighborhood. We reconcile insurance reimbursements against claims and track the timing differences that make healthcare accounting distinct.

Common Questions

You're based in Andover. Why would a Back Bay business work with you?

Bookkeeping and advisory work happens digitally. Your location on Newbury or Boylston doesn't require a Back Bay accountant. We're 30 minutes north on 93 when meeting makes sense, but most work flows through screens. You get experienced support without paying for downtown overhead.

What does monthly bookkeeping cost for a Back Bay business?

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

Can we meet in person?

Yes. We can come to your Back Bay office or meet at a convenient spot. Most clients find that once things are running smoothly, they prefer the efficiency of remote communication.

How quickly can you get started?

Usually within a week. If your books are behind, we start with catch-up work to get you current. If they're already in reasonable shape, we move straight into monthly service.

Do you work with businesses that have employees in multiple states?

Yes. Multi-state payroll and compliance is something we handle regularly. We manage the registration, tax deposits, and filings across jurisdictions so you stay compliant as your team grows.
