The verdict in three sentences
The number one risk for a legal department is not software price, it is the missed deadline: a single limitation incident can cost a case and trigger your liability. A specialist SaaS at 30-70 EUR/user/month provides standard alerts; custom software at 20,000-45,000 EUR models your own deadline rules, your document management and your approval flows. The right question is the cost of an avoided incident against the cost of securing your process.
2026 costing: SaaS vs custom
SaaS is predictable and fast; custom becomes an asset tailored to your practice areas (litigation, employment, IP) and internal rules.
| Criterion | Legal SaaS | Custom |
|---|---|---|
| Upfront cost | 0 to 1,500 EUR | 20,000 to 45,000 EUR |
| Monthly cost | 30 to 70 EUR / user | Hosting 50 to 180 EUR / month |
| Cost for 6 users over 3 years | 6,500 to 15,100 EUR | 21,800 to 51,000 EUR |
| Deadline rules | Predefined | Custom (limitation, foreclosure) |
| Integrated DMS | Standard | Fits your filing plan |
| Rollout time | 2 to 5 weeks | 3 to 5 months |
| Extensibility | Vendor-bound | Unlimited |
For a team of 3-4 lawyers, SaaS is enough; from 6-8 users with specific deadline rules, custom is justified. The often-underestimated point is rule modelling: a limitation period varies by practice area, starting point and interruptions. A SaaS applies a generic rule; custom encodes your own business rules, so the deadline date shown is correct from the moment the case is created, without manual reprocessing that reintroduces risk.
The real cost of a missed deadline
A missed limitation period or forgotten hearing cannot be recovered. Here is the risk scale that justifies the investment.
| Incident | Consequence | Financial impact (2026 estimate) |
|---|---|---|
| Missed limitation | Loss of the right to act | Case value + liability |
| Forgotten hearing | Default judgment | 5,000 to 50,000 EUR by stake |
| Late client follow-up | Delayed collection | +15 to 30 days of cash |
| Lost document (no DMS) | Redo the work | 2 to 8 h of lawyer time |
| No approval trail | Liability dispute | Defence cost + reputation |
Alerts at D-30, D-7 and D-1, doubled with automatic hierarchical escalation, bring this risk to a residual level. You must, however, tell cosmetic alerts from reliable ones: the first shows in a screen corner and gets lost in the flow; the second requires an acknowledgement, escalates to the manager if unanswered, and leaves a timestamped trace. That trace is doubly useful: it protects the lawyer in a dispute, and it lets management measure real workload and anticipate deadline peaks rather than endure them.

Mini case study
Sophie, legal director of an industrial SME in Amsterdam, runs 340 active cases with 5 lawyers. Two near-miss deadline incidents a year keep her under stress; a single lost case would mean 40,000 EUR of risk. She invests 32,000 EUR in custom software with automatic deadline calculation, multi-level alerts and DMS. Total first-year cost: about 34,000 EUR. If the tool avoids just one major incident every two years, it pays off; in practice it also removes 4 h/week of manual tracking, roughly 9,000 EUR/year of recovered lawyer time.
FAQ
What budget to secure my deadlines in 2026? A SaaS at 30-70 EUR/user covers standard cases for a few hundred euros a month. Custom starts at 20,000 EUR but models your exact limitation rules.
Are automatic alerts reliable? Yes, if they are multi-level (D-30, D-7, D-1) with hierarchical escalation and acknowledgement. An alert without read receipt offers no legal protection.
Is DMS essential? Yes: a lost document costs 2 to 8 h of lawyer time to reconstruct. DMS with a filing plan and full-text search is the foundation of reliability.
How long to deploy? 2 to 5 weeks for SaaS, 3 to 5 months for custom. The deadline + alerts module usually ships first, in 8-10 weeks.
Can existing cases be migrated? Yes. Plan 3,000 to 8,000 EUR of data migration depending on volume and source quality (Excel, old software, paper).
