What the pricing really means
Bill4Time publishes their pricing upfront, which is a good sign. ProLaw requires you to contact sales for a quote. When a company hides pricing, it usually means the cost is high enough that they want a salesperson to justify it before you see the number. Always ask for total year-one cost, not just the monthly subscription.
Where Bill4Time wins
- $27/user for time tracking and billing is one of the cheapest legal billing tools available
- 14-day free trial is generous
- Trust accounting included even on the cheapest plan
- Also works for non-legal professionals (accountants, consultants) if your practice has mixed billing needs
Where ProLaw wins
- Backed by Thomson Reuters with direct integration to Westlaw and Practical Law
- Enterprise-grade financial management with LEDES billing, matter budgets, and profitability analysis
- Trust accounting with multi-bank, multi-currency support for large international firms
- Court rule calendaring included
Where Bill4Time falls short
- Lacks modern features like intake forms, eSignature, document automation, and email management
- Case management is only available from $47/user and is basic compared to dedicated PM tools
- No conflict checks built in
- The interface is functional but plain
Where ProLaw falls short
- G2 rating of 3.5 and Capterra 3.8 indicate significant user frustration with the interface
- No public pricing — likely $200+/user based on the enterprise positioning
- No client portal, no mobile app, no eSignature, no intake forms
- Implementation takes months, not days
Who is each product built for?
Bill4Time
