The verdict in three sentences
The cost of law firm practice management software is decided on billable hours recovered, not on the licence price. A SaaS at EUR 30-70/user/month suffices for firms under 15 attorneys; beyond that, or with complex e-filing, trust accounting and fee-billing needs, a custom build at EUR 45,000-100,000 (5-8 month lead time) pays off. The decisive factor: each attorney who bills one more hour a day is worth several thousand euros a month.
Essential vs premium modules
Not every firm needs everything. 2026 order of magnitude for custom development per module.
| Module | Type | Indicative cost | Lead time |
|---|---|---|---|
| Matter management | essential | EUR 10,000-18,000 | 5-7 wks |
| Time tracking + entry | essential | EUR 8,000-15,000 | 4-6 wks |
| Fee billing | essential | EUR 9,000-16,000 | 5-7 wks |
| Secure client portal | premium | EUR 8,000-14,000 | 4-6 wks |
| E-filing integration | premium | EUR 6,000-12,000 | 4-6 wks |
| Trust accounting | premium | EUR 7,000-13,000 | 5-7 wks |
| Dashboards + BI | premium | EUR 6,000-11,000 | 4-5 wks |
An essential core (first three modules) sits around EUR 30,000-45,000. Full premium pushes the total toward EUR 90,000-100,000.
ROI: billable hours recovered
The main gain is capturing hours currently lost. Assumption: average rate EUR 180, an 8-attorney firm.
| Hours/day recovered per attorney | Hours/month (8 attorneys) | Fees/month | Fees/year |
|---|---|---|---|
| 0.25 h | 44 h | EUR 7,920 | EUR 95,040 |
| 0.5 h | 88 h | EUR 15,840 | EUR 190,080 |
| 1 h | 176 h | EUR 31,680 | EUR 380,160 |
Even in the low case (0.25 h/day), a EUR 70,000 build pays for itself in under a year. Add maintenance of EUR 500-1,200/month to the TCO.
Mini case study
Me Lefevre, managing partner of a New York firm (8 attorneys, business law), finds his associates fail to log an average 0.5 billable hour per day. He invests EUR 72,000 in custom software (matters + time tracking + billing + e-filing), plus EUR 900/month maintenance. Automated time tracking recovers 88 h/month at EUR 180, i.e. EUR 190,080/year. Return on investment from the fifth month of operation.

FAQ
How much does law firm practice management software cost in New York in 2026?
Between EUR 45,000 and 100,000 custom depending on modules, or EUR 30-70/user/month as SaaS. Custom becomes relevant as soon as billing or compliance (e-filing, trust accounting) falls outside the standard.
Does time tracking really change billing?
Yes, it is the highest-ROI item. Recovering even 0.25 billable hour per attorney per day is close to EUR 95,000/year for an 8-attorney firm at EUR 180/h.
Can it connect to court e-filing systems?
Yes, via available interfaces. It is a premium module (EUR 6,000-12,000) that avoids double entry and secures exchanges with the courts.
What is the go-live timeline?
Allow 5 to 8 months for a full scope. An essential core (matters, time, billing) can ship in 4 months then be enriched iteratively.
What does the EUR 500-1,200/month maintenance include?
Corrective maintenance, security updates, minor evolutions and support. The price depends on functional scope and chosen SLA level.
