Monthly Bookkeeping & Financial Statement Preparation

High-growth firms can't afford delayed reconciliations, miscategorized expenses, or disorganized records. When your books are inaccurate, everything downstream, tax planning, cash flow forecasting, strategic decisions, gets shakier along with them.


Our outsourced and virtual bookkeeping services in Lexington, MA give you a dependable financial foundation while your team focuses on growth. We handle monthly account reconciliations, lender-ready financial statement preparation, QuickBooks setup and catch-up work, and multi-state payroll and expense tracking for businesses with remote staff across New England. Instead of spending executive hours reviewing receipts, you get clean, decision-useful financial data every month.


QuickBooks Cleanup & Catch-Up Bookkeeping

Even high-revenue Lexington businesses can fall months behind after rapid growth or a software transition. If your QuickBooks file has become hard to audit or your tax prep has stalled, we can bring things back into order quickly.


Our Lexington QuickBooks cleanup and catch-up services untangle duplicate entries and unreconciled accounts, rebuild past records so your filings are audit-ready, and structure accurate historical data for lines of credit, acquisitions, or partnership reviews. Catch-up bookkeeping isn't just about clearing a backlog. It's the first step toward running your business on real data instead of guesswork.

Strategic Tax Planning & Multi-State Compliance

Strategic Partnership That Goes Beyond Compliance


Clean bookkeeping is the starting line. Tax optimization is where the real value gets unlocked. Traditional tax prep looks backward at what already happened; our planning looks ahead, so you keep more of what you earn.


In a market as commercially dense as Lexington and Middlesex County, we help closely held businesses navigate entity structuring for S-Corps, LLCs, and multi-entity setups, manage tax exposure across Massachusetts, New Hampshire, and New England, and identify credits, depreciation strategies, and executive compensation planning before year-end closes in.

Fractional CFO Services & Strategic Advisory

Clarity, Confidence, and Strategic Direction

Our fractional CFO services in Lexington, MA give you executive-level financial intelligence without a $250k+ full-time salary: cash flow forecasting and runway modeling, margin and profitability analysis by client or project, and KPI development with board-ready reporting for leadership and investors.

Regional Expertise That Extends Beyond Town Lines

Choosing an accounting partner means balancing real technical expertise with someone you can actually reach. Based just minutes away in Chelmsford, Patrick Kimera and the KPI Solutions team have worked with more than 200 businesses across Middlesex County and the Merrimack Valley over 20-plus years, so the Middlesex corridor's pace and pressures aren't a mystery to us.


We keep pricing upfront and predictable, with no hidden billing surprises buried in the fine print.

Frequently Asked Questions From

Lexington Business Owners

  • How much do monthly bookkeeping services cost in Lexington, MA?

    Pricing depends on transaction volume, payroll complexity, and whether multi-state compliance applies. We offer transparent, fixed monthly packages so your investment is predictable from month to month.



  • Can you clean up messy QuickBooks records from previous years?

    Yes. Our catch-up services audit, reconcile, and correct historical records so your business is tax-ready and lender-compliant.


  • Do you work with contractors and trade businesses?

    You get secure, real-time access to your financials through cloud systems like QuickBooks Online, paired with direct support from a local team who knows your business.


  • How does bookkeeping connect to your fractional CFO services?

    Clean bookkeeping is the data our fractional CFOs use to build cash flow forecasts, run margin analysis, and guide bigger growth decisions. One depends on the other.


  • Do you work with businesses outside of Lexington?

    Absolutely. Alongside Lexington, we support business owners across Middlesex County, including Weston, Newton, Chelmsford, Westford, and Burlington.


  • Do you offer flat-fee or fixed-price engagements?

    In most cases, yes. We'd rather quote a clear monthly or project fee upfront than bill you by the hour and leave you guessing what's coming.


  • Do you work with specific industries in Lexington, like life sciences or tech?

    We work with a mix of professional services firms, medical groups, tech ventures, and trade businesses. If your industry has unusual reporting or compliance needs, that's exactly the kind of complexity we're set up to handle.
