Bookkeeping for Lexington Small Businesses

Bookkeeping, payroll, and financial services for Lexington businesses. Monthly reports, clean records, and a team that values getting it right.

Bookkeeping for Lexington Businesses

Vast Accounting provides small business bookkeeping services for companies in Lexington and across the Greater Boston area. Monthly bookkeeping, payroll processing, accounts payable and receivable, and catch-up work when records have fallen behind. The financial support you need without adding full-time staff.

Lexington has a concentration of professional practices and service businesses run by people who expect competence and reliability. That matches how we work. We bring 15+ years of hands-on accounting experience to every client relationship, and we treat your books with the same care we would our own.

Ongoing Bookkeeping

Transaction categorization, bank reconciliation, monthly close, and financial statements delivered consistently. Your books stay current every month without becoming your weekend project.

Payroll Services

Full payroll processing including wage calculations, tax withholdings, direct deposits, and quarterly filings. Year-end W-2s handled. Your team gets paid on time and the compliance stays current.

Catch-Up Bookkeeping

Books a few months or years behind? We reconstruct the records, reconcile the accounts, and get you to a clean starting point. Most businesses that come to us started exactly there.

Accounts Payable & Receivable

Vendor payments tracked and scheduled. Customer invoices sent and followed up. Aging reports that show where cash is tied up and what needs attention.

Lexington Businesses We Work With

Many Lexington business owners we talk to started managing their own finances and found it worked until it didn’t. The business grew. The records got complicated. Tax time became stressful. They needed someone who could take it over and get it right without requiring constant oversight.

We work with professional services firms, healthcare practices, consultants, and local businesses doing anywhere from $100K to several million in revenue. Businesses that need real bookkeeping but aren’t ready to hire someone in-house.

Professional Services

Consultants, attorneys, financial advisors, and agencies. Many operate from home offices or small commercial spaces in Lexington. We handle the books so you can focus on billable work and client relationships.

Healthcare Practices

Dental offices, therapy practices, chiropractic clinics, and specialty care providers. We manage the timing between services rendered and insurance payments, patient balances, and the receivables tracking that healthcare accounting requires.

Tech and Software

Software companies and startups near the Route 128 corridor. Subscription revenue tracking, financial planning for growth, and books that are ready when investors or lenders ask questions.

Local Service Businesses

Childcare centers, tutoring services, salons, and retail shops serving Lexington families. We handle the monthly financials so you can run the business without drowning in paperwork.

Common Questions

Do you work with businesses throughout Lexington?

Yes. We work with businesses in Lexington Center, along Massachusetts Avenue, in the commercial areas near Route 128, and throughout town. Most of our work happens remotely, so your specific location doesn't matter.

What does monthly bookkeeping cost?

Starting around $199 per month depending on transaction volume and complexity. We provide exact pricing after learning about your business.

You're based in Andover. Can we meet in person?

Yes. Andover is about 25 minutes from Lexington. We can meet when it makes sense, though most clients find remote communication works well for day-to-day needs.

My books are behind. Can you help?

That's common. We do catch-up work to get your records current, then transition into monthly service so you don't fall behind again.

Do you handle payroll and Massachusetts taxes?

Yes. Full payroll processing including tax deposits, quarterly filings, W-2s, and year-end compliance. Massachusetts withholding and unemployment handled.
