Bookkeeping For Law Firms in Greater Boston

Helping Massachusetts Attorneys keep their books organized, trust accounts clear, and financials ready for taxes

Running a law firm already demands your full attention. Client matters, court deadlines, and managing a growing case load. Your bookkeeping should not be the thing that follows you home at the end of the day.


We help law firms across Greater Boston and Middlesex County keep your QuickBooks organized, help track client reimbursements properly, and maintain clear records for your operating and IOLTA accounts.

Running a Law Firm Is Hard Enough and Your Books Shouldn’t Be Making It Worse

Your firm has grown over the past few years; and the financial side of the business has become complex.


You deal with:

  • Recording daily client payments and deposits properly
  • Keeping track of expenses for client reimbursements
  • An IOLTA that has grown more than you could have imagined
  • Accurately transferring funds from your IOTLA to Operating when revenue is recognized.
  • Managing monthly profitability budgets against attorney hourly billings


Having to do all these things and then learn how everything effects your accounting, while trying to learn QuickBooks at the same time, is frustrating.


You need a bookkeeper who has done it before and can help you.
