Atlantic Associates Software

Updated 2026-03-19

Desktop legal time tracking and billing software (product name: TimeManager) for Mac and Windows, for 1-100 person workgroups. Founded 1992 in Sudbury, MA by Tim Coogan. Perpetual license model ($895/user per Capterra, free 30-day trial). Features: time tracking with built-in timer, invoicing, LEDES invoice generation, client/matter management. Can run as client/server within local network. Mac-native legal billing was a rare differentiator at launch but modern cloud tools (Clio, CosmoLex) now work on Mac via browser. Desktop-only architecture: no cloud sync, no mobile app, no web access — significant limitation for remote/hybrid firms. Also makes ClassManager (educational). Capterra rating 4.9/5 (11 reviews). 24/7 live rep support. Not mentioned in major ‘best legal billing’ roundup articles. Zero Reddit community presence. Website actively maintained (©2026). Competes with Clio ($39-129/mo), CosmoLex ($99/mo), LeanLaw. Best fit: cost-conscious solo/small firms wanting a one-time purchase over monthly SaaS subscriptions, especially Mac users comfortable with desktop software.

What practitioners struggle with

Real frustrations from legal professionals — the problems Atlantic Associates Software addresses (or should address). Sourced from practitioner reviews, Reddit threads, and case studies.

Attorneys reconstruct their day at 9pm, guessing at time entries — studies show 10-15% of billable hours vanish when you don't track in real time

Billing, Time & Finance 90 vendors affected Solo practitioner · Small firm (2–10) · Mid-size firm (11–50) · Large firm (51–200)

Solo attorney paying $500+/month across 6 different software tools that don't share data — needs one system that actually handles the basics without nickel-and-diming

Firm Operations & Growth 99 vendors affected Solo practitioner · Small firm (2–10)

Practice management and accounting are two different planets — billing lives in the PM tool, financials live in Xero or QuickBooks, and the sync either doesn't exist or breaks every month during reconciliation
