The verdict in three sentences
For a 25-lawyer-and-staff firm, legal SaaS costs in 2026 between 40 and 90 EUR/seat/month, i.e. 10,000 to 27,000 EUR/year. The real return comes from recovered billable hours — 1 to 3 h/week/lawyer via automatic timesheets and the document vault. GDPR, professional secrecy and France-based hosting weigh as much as price in the choice.
Cost of vertical legal solutions in 2026
The French market (Secib, Kleos by Wolters Kluwer, Jarvis Legal, Diapaz) bills per seat with optional modules. Here are the orders of magnitude for 25 seats.
| Solution | Price/seat/month | Annual cost (25 seats) | Strengths |
|---|---|---|---|
| Jarvis Legal | 40-60 EUR | 12,000-18,000 EUR | Full web, ergonomics |
| Secib néo | 50-75 EUR | 15,000-22,500 EUR | Rich, integrated e-court |
| Kleos (Wolters Kluwer) | 55-85 EUR | 16,500-25,500 EUR | Legal ecosystem |
| Diapaz | 45-70 EUR | 13,500-21,000 EUR | Lawyer accounting |
| Custom module | 35-75k EUR build | 5,250-11,250 EUR/yr maint. | Own workflows |
On top of licences, compliance and onboarding line items are often forgotten in the initial estimate.
| Line item | 2026 range | Nature |
|---|---|---|
| Certified France hosting (HDS/SecNumCloud) | 1,500-5,000 EUR/yr | Recurring |
| E-court connector | included or 1,000-3,000 EUR | Setup |
| Encrypted document vault | 2,000-6,000 EUR | Setup |
| Historical file migration | 3,000-9,000 EUR | Migration |
| Training (25 seats) | 3,000-7,000 EUR | Year 1 |
The real issue: recovered billable hours
A lawyer who logs time manually always loses some. Automatic timesheets and integrated time-based billing recover 1 to 3 billable hours per week per lawyer. For a firm of 15 billing lawyers.
| Scenario | billable h lost/week/lawyer | Avg hourly rate | Annual loss (15 lawyers) |
|---|---|---|---|
| Manual entry | 3 h | 180 EUR | 421,200 EUR |
| SaaS with basic timesheet | 1.5 h | 180 EUR | 210,600 EUR |
| Well-configured tool + mobile entry | 0.5 h | 180 EUR | 70,200 EUR |
Recovering just 1 billable hour/week/lawyer represents 140,400 EUR/year of revenue — dwarfing software cost. That is the central argument for a partner.
Mini case study
Me Lefebvre, partner in a 25-person business firm in Lille (15 billing lawyers), is torn between Kleos (22,000 EUR/yr) and a custom module at 58,000 EUR + 8,700 EUR maintenance, connected to his vault and accounting. Today, manual entry loses on average 2 billable hours/week/lawyer, i.e. 280,800 EUR/yr. Bringing the loss to 0.5 h recovers 210,600 EUR/yr. The custom build, paid back in 8 months on that gain alone, also gives him control over professional secrecy and France hosting. He approves the build.

FAQ
How much to equip 25 lawyers in 2026?
Between 10,000 and 27,000 EUR/yr in SaaS licences, plus certified hosting and migration. First year, training included, often lands between 18,000 and 40,000 EUR.
Does professional secrecy require France hosting?
Strongly recommended: favour certified HDS or SecNumCloud hosting in France, with vault encryption. Budget 1,500 to 5,000 EUR/yr for that guarantee.
Is the e-court connector native?
With Secib and Kleos, often yes. Otherwise budget a 1,000-3,000 EUR connector. Check compatibility before signing.
Custom or SaaS for a 25-person firm?
SaaS is enough if your workflows are standard. As soon as time-based billing or processes are specific, a custom module (35,000-75,000 EUR) pays off fast through recovered hours.
What ROI from automatic timesheets?
1 to 3 billable hours recovered per week per lawyer. At 180 EUR/h across 15 lawyers, each weekly hour is worth 140,400 EUR/yr of revenue.
