The verdict in three sentences
Without deadline alerts, a legal department managing 2,000 contracts suffers unwanted automatic renewals, missed notice periods and forgotten price indexations every year. In 2026, the choice is between an off-the-shelf CLM at EUR 30 to 80 per user per month and a custom application at EUR 35,000 to 90,000 excl. VAT, depending on user count and required integrations. In most cases, avoiding a single automatic renewal per quarter pays for the tool within the first year.
What the application must do
The general counsel's need at a mid-sized company fits in one sentence: never again discover a deadline after the notice date. Features rank as follows.
| Feature | Priority | Relative effort | Expected gain |
|---|---|---|---|
| Single contract repository (metadata, PDFs) | Essential | 20% | End of scattered spreadsheets |
| Automatic notice date calculation | Essential | 10% | Zero missed notices |
| Email and Teams alerts at D-90, D-60, D-30 | Essential | 10% | Earlier decisions |
| Approval workflow (legal, procurement, finance) | Important | 15% | Decision traceability |
| Integrated eIDAS e-signature | Important | 10% | Signing cycle from 10 days to 2 |
| AI clause extraction | Useful | 15 to 20% | Faster legacy migration |
| ERP and procurement tool connection | Useful | 15% | Commitments visible to finance |
| Commitments dashboard | Important | 10% | Management oversight |
Migrating the 2,000 existing contracts is often the real project: without assisted extraction, plan 10 to 20 minutes per contract, or 330 to 670 hours of data entry.
Off-the-shelf CLM or custom: 2026 comparison
| Criterion | SaaS CLM | Custom application |
|---|---|---|
| Entry cost | EUR 2,000 to 15,000 excl. VAT setup | EUR 35,000 to 90,000 excl. VAT |
| Recurring cost | EUR 30 to 80 per user per month | 8 to 15% of build per year in maintenance |
| 25 users over 5 years (order of magnitude) | EUR 45,000 to 120,000 excl. VAT plus setup | EUR 50,000 to 140,000 excl. VAT |
| Time to go live | 4 to 10 weeks | 3 to 6 months |
| Fit with internal processes | Limited to configuration | Complete |
| ERP and SSO integration | Depends on available connectors | Tailored |
| Ownership of data and code | Vendor | Client |
| Hosting in France or the EU | Varies by vendor | Client's choice |
Custom makes sense when users exceed 30 to 50, when workflows are specific (multi-subsidiary group, public contracts) or when the ERP demands deep integration. Below that, a well-configured off-the-shelf CLM is often the more rational choice.
Cost of signature and supporting components
| Component | 2026 price (order of magnitude) | Comment |
|---|---|---|
| eIDAS simple e-signature | EUR 1 to 3 per envelope | Enough for most commercial contracts |
| eIDAS advanced e-signature | EUR 3 to 8 per envelope | High-stakes contracts |
| eIDAS qualified e-signature | EUR 10 to 25 per signature | Maximum evidential value |
| AI clause extraction | EUR 0.10 to 1 per document | For legacy migration |
| Hosting and backups | EUR 100 to 500 per month | Depending on document volume |
| Legally compliant archiving | EUR 0.5 to 2 per document per year | Optional depending on sector |
Mini case study
Illustrative scenario: Marc, general counsel of a mid-sized distribution company in Bordeaux, tracks 2,000 supplier and customer contracts in spreadsheets. Last year, 12 contracts renewed automatically when the company wanted to renegotiate or terminate, at an average value of EUR 8,000 per contract.

Estimated avoidable loss: 12 x EUR 8,000 = EUR 96,000 a year. A custom app at EUR 60,000 excl. VAT, plus EUR 6,000 a year in maintenance and EUR 2,400 in signatures (1,200 envelopes at EUR 2), costs EUR 68,400 in year one. Even avoiding only 9 of the 12 renewals, or EUR 72,000, the tool pays back within the first year, then yields about EUR 63,600 in net gain per year.
FAQ
How much does a custom contract management app cost in 2026?
Between EUR 35,000 and 90,000 excl. VAT depending on workflows, ERP integrations and legacy migration. Maintenance then runs at 8 to 15% of the build per year.
Does a simple e-signature have legal value?
Yes, the eIDAS regulation recognises its evidential value, and it covers most commercial contracts for EUR 1 to 3 per envelope. Keep qualified signatures for very high-stakes documents.
When does custom become cheaper than a CLM?
Generally above 30 to 50 users or with very specific workflows. At 50 users and EUR 60 per month, a CLM costs EUR 36,000 a year, the price of a custom build.
How do we migrate 2,000 existing contracts?
AI-assisted extraction pre-fills dates, parties and term, then a lawyer validates. Plan 3 to 5 minutes per contract instead of 10 to 20 with manual entry.
How long until go-live?
Plan 3 to 6 months for a custom build, including 3 to 4 weeks of discovery. Deadline alerts can ship as the first release by month two.
