The verdict in three sentences
A legal SaaS (40 to 90 EUR per user per month) is enough for most firms to run matters, a procedural calendar and time-based billing, while a custom build (50,000 to 130,000 EUR) becomes essential once confidentiality, integrations and specific workflows turn critical. The decisive benefit is a 20 to 30 % cut in administrative time and finally exhaustive time-based billing. Confidentiality (privilege, privacy law, encrypted vault) is not optional: it is the non-negotiable foundation.
The features that make the difference
A law firm handles sensitive matters with hard deadlines. Four building blocks structure the tool: the matter (parties, documents, history), the procedural calendar (appeal deadlines, hearings), time-based billing (timesheet + fees) and the secure DMS (encrypted digital vault).
| Module | Legal SaaS (per user/month) | Custom (one-off) | Key stake |
|---|---|---|---|
| Matter management | 12-25 EUR | 12,000-28,000 EUR | 360° matter view |
| Procedural calendar + alerts | 8-18 EUR | 9,000-20,000 EUR | Zero missed deadline |
| Time-based billing (timesheet) | 10-22 EUR | 10,000-24,000 EUR | +15-25 % fees captured |
| Secure DMS / vault | 6-15 EUR | 12,000-30,000 EUR | Privilege guaranteed |
| Secure client portal | 4-10 EUR | 8,000-20,000 EUR | Traceable encrypted exchanges |
| Privacy compliance + logging | included | 6,000-16,000 EUR | Audit and access proof |
SaaS or custom: which trade-off?
SaaS wins on entry cost and go-live speed; custom wins on data sovereignty, no per-seat subscription and deep integrations (accounting, e-signature, court filing).
| Criterion | Legal SaaS | Custom |
|---|---|---|
| Year 1 cost (12-lawyer firm) | ~9,400 EUR (65 x 12 x 12) | 85,000 EUR + 10,000 EUR maintenance |
| 36-month total | ~28,200 EUR | ~105,000 EUR |
| Data sovereignty | shared | full |
| Workflow customisation | standard | full |
| Time to deploy | 3-6 weeks | 4-7 months |
| Administrative time saved | 20-30 % | 20-30 % |
For a firm under 10 lawyers with standard workflows, SaaS stays rational. Beyond that, or once confidentiality demands sovereign hosting, custom becomes a defensible investment.
Mini case study
Me Diop, partner at a 12-lawyer business firm in Dakar with European clients, is losing fees for lack of a reliable timesheet and fears a breach on sensitive matters. He invests 92,000 EUR in a custom tool: matters, procedural calendar with alerts, time-based billing and an encrypted vault. Over 12 months the firm captures 22 % more fees thanks to finally-tracked time (on 1.4M EUR billed, that is ~300,000 EUR), cuts administrative time by 25 % and eliminates missed procedural deadlines. Payback is reached in under 5 months.

How is privilege protected?
Through an encrypted digital vault, access logging (who saw what, when) and compliant hosting. In custom builds, sovereign hosting and end-to-end encryption are configurable to your professional obligations.
Does time-based billing really raise fees?
Yes: a timesheet integrated into the matter captures work usually forgotten, commonly 15 to 25 % more fees captured without working more.
Does the procedural calendar prevent missed deadlines?
Yes: every deadline (appeal, hearing, limitation) triggers multiple alerts. This single feature justifies the tool for most litigation practices.
How long to deploy?
A legal SaaS is live in 3 to 6 weeks. A full custom build takes 4 to 7 months depending on integrations (accounting, signature, court platforms).
Does privacy law apply if my clients are outside the EU?
As soon as you process data of people located in the EU, yes. Access logging and a processing register are essential; budget 6,000 to 16,000 EUR for this in custom.
