Bill by the hour. Not by the headache.

Your IOLA reconciliations shouldn't require more attention than your opening arguments. After 30+ years keeping NYC law firms compliant and profitable, we speak fluent legalese—trust accounting, partner draws, Bar requirements—so you can focus on what you bill for.

The Legal Accounting Reality Check

Most CPAs break into a cold sweat at "three-way trust reconciliation." Not us.

We've navigated hundreds of firms through the peculiar maze of legal accounting—where client funds mingle with operating accounts about as well as opposing counsel at depositions. One mishandled retainer, one sloppy trust transfer, one confused Bar examiner, and suddenly you're the case study, not the counsel.

  • We've seen it all.
  • We've fixed most of it.
  • We help prevent the rest.

How We Keep Your Practice Profitable (and Compliant)

IOLA & Trust Accounting

Three-way reconciliations so clean, Bar examiners won't have questions. Audit-ready records that make compliance reviews surprisingly pleasant.

Billing & Timekeeping Integration

LeanLaw, QuickBooks Online, whatever you're running—we make it talk to your books fluently. Less time chasing invoices, more time billing hours.

Monthly Financial Reporting

P&Ls that tell the real story: which practice areas profit, which partners produce, which expenses need interrogation. Automated accuracy with human insight.

Tax Planning & Preparation

Federal, state, city—we handle the trifecta. Strategic planning that treats partner distributions like the tax events they are, not the surprises they shouldn't be.

Payroll & Compliance

Classifications clear enough to satisfy the DOL's finest. Because "of counsel" means something specific to more than just your letterhead.

Advisory & CFO Support

Financial counsel for growth, succession, and partner planning. From cash flow analysis to practice valuations—the numbers that shape your firm's future.

Areas of Expertise

  • Solo practitioners who need big-firm compliance
  • Boutique practices with boutique complications
  • Multi-partner firms with multi-layered needs
  • Franchised groups with standardized chaos
  • Litigation, transactional, specialty—if it requires an ESQ, we've done the books

Questions law firms actually ask us

“But switching accountants is a nightmare.” +
It’s a Tuesday for us. We migrate from whatever chaos you’re in—QuickBooks Desktop, Excel masterpieces, shoebox receipts—into clean, automated systems. Most firms are fully transitioned in two weeks.
"How do I know you won't disappear after setup?" +
We're part of Numera, a national network. That means you get the expertise of a specialist, with the staying power of an institution behind us. You're not betting on a one-person shop.
“What if my current system is ‘working fine’?” +
If you’re reading this at 9pm wondering if your trust account balances, it’s not working fine. It’s working barely. We show you where the cracks are—and how to seal them before auditors do.
“Can my legal assistant just keep handling it?” +
They mean well. But IOLA doesn’t grade on effort. One unreconciled ledger or missed transfer can put a license at risk. Compliance requires CPA-level oversight, every single month.

Stop managing your finances.
Start trusting them.

Two paths forward: a quick check on exposure, or a full transition plan. Either way, you’ll know exactly where you stand.
