The verdict in three sentences
For a mid-sized company managing 2,500 active contracts that still misses renewal deadlines, a custom contract management app costs EUR 35,000 to 70,000 excl. VAT and ships in 3 to 5 months. An off-the-shelf CLM starts faster but costs EUR 15,000 to 40,000 a year, or EUR 75,000 to 200,000 over 5 years. Custom wins when your approval flows are specific or when you want to own your data and AI models; the market CLM wins if your need is standard and urgent.
Off-the-shelf CLM or custom app?
Figures are 2026 ballpark ranges for a legal department of 4 to 8 lawyers, with 40 to 80 business users in read access.
| Criterion | Off-the-shelf CLM | Custom app |
|---|---|---|
| Year 1 cost | EUR 20,000 to 55,000 excl. VAT (licence + setup) | EUR 35,000 to 70,000 excl. VAT |
| Annual cost after | EUR 15,000 to 40,000 excl. VAT | EUR 5,000 to 10,000 excl. VAT (hosting + maintenance) |
| Cumulative 5-year cost | EUR 80,000 to 215,000 excl. VAT | EUR 55,000 to 110,000 excl. VAT |
| Time to go-live | 6 to 12 weeks | 3 to 5 months |
| Per-user pricing | Yes, EUR 50 to 150 per seat per month | No |
| Specific approval workflows | Configurable within limits | Unlimited |
| Ownership of data and code | No | Yes |
| Hosting in France | Depends on vendor | Your choice, SecNumCloud possible |
Above 30 users or a 3-year horizon, custom generally becomes cheaper, provided the scope stays under control.
Budget by feature
| Feature | What it does | 2026 budget excl. VAT | Timeline |
|---|---|---|---|
| Contract repository | Contract record, counterparties, amounts, attachments, full-text search | EUR 8,000 to 14,000 | 4 to 5 weeks |
| Renewal alerts | Termination notice, auto-renewal, price reviews, email and Teams reminders | EUR 4,000 to 8,000 | 2 weeks |
| AI clause extraction | Term, notice period, liability cap, governing law, penalties | EUR 8,000 to 16,000 | 4 to 6 weeks |
| Approval workflow | Legal, procurement, finance, executive circuit, thresholds by amount | EUR 5,000 to 10,000 | 3 weeks |
| E-signature | Yousign or Docusign integration, eIDAS advanced signature | EUR 3,000 to 6,000 | 1 to 2 weeks |
| Template library | Standard clauses, contract generation from forms | EUR 4,000 to 9,000 | 2 to 3 weeks |
| Dashboard | Commitments per supplier, 90-day renewals, at-risk contracts | EUR 3,000 to 7,000 | 2 weeks |
A core of "repository + alerts + AI + signature" lands around EUR 35,000 to 45,000 excl. VAT. The full version reaches EUR 60,000 to 70,000 excl. VAT. Migrating existing contracts (2,500 PDFs, often scanned) adds EUR 4,000 to 8,000 with OCR and human verification of extracted fields.
AI extraction: what to demand
In 2026, AI clause extraction reaches 90 to 95% accuracy on well-structured French contracts, less on old scans. Demand three guarantees: human validation of every critical field (end date, notice period), data processing within the European Union with no reuse for model training, and traceability of the source passage for every extracted value. Model usage costs stay modest: EUR 50 to 200 a month for 2,500 contracts and 100 new ones a month.
Mini case study
Isabelle, general counsel of a mid-sized services company in Paris, oversees 2,500 active contracts with 5 lawyers. Last year, 4 supplier contracts auto-renewed for lack of an alert, at an average extra cost of EUR 28,000 each.
- Cost of missed renewals: EUR 112,000 in one year.
- Time spent searching for clauses and dates: 6 hours per lawyer per week, about 1,300 hours a year, valued at EUR 85 an hour, or EUR 110,500.
- Custom app chosen: EUR 58,000 excl. VAT, delivered in 4 months, plus EUR 7,000 a year.
- Measured time saving: 60% of searches avoided, or EUR 66,300 a year, and zero missed renewals in year one.

FAQ
How long does it take to build a contract management app?
Allow 3 to 5 months, including 2 weeks of scoping with legal and procurement. Renewal alerts can go live by week 6.
Is AI clause extraction reliable?
It reaches 90 to 95% accuracy on born-digital contracts. Critical fields such as end date and notice period must always be validated by a lawyer, which takes about 2 minutes per contract.
Is e-signature legally binding?
Yes, an advanced electronic signature under the eIDAS regulation is admissible for the vast majority of commercial contracts. Integration costs EUR 3,000 to 6,000 excl. VAT, plus EUR 1 to 3 per signature depending on the provider.
Where is the data hosted?
In France, with an ISO 27001 or SecNumCloud certified host if your sector requires it. Hosting costs EUR 100 to 350 excl. VAT a month for this volume.
Can the app connect to our ERP?
