The verdict in three sentences
For a legal team handling more than 1,000 contracts a year, a custom workflow connected to the Yousign or Docusign API costs between EUR 25,000 and 60,000 excl. VAT in 2026. The main gain is signing time, which drops from 15 days to 3 days on average, along with full version traceability. Above 800 contracts a year with recurring clauses, a custom tool becomes cheaper than a standard per-seat CLM subscription.
What a custom contract workflow includes
The general counsel of a distribution network receives franchise agreements, amendments, NDAs and commercial terms requests every week. Today, versions travel by email, a sales rep edits a clause without telling anyone, and nobody knows which version was actually signed. A custom application structures this flow in five steps: request, generation from a template, negotiation with deviation tracking, internal approval, signature and archiving.
| Module | Function | Indicative 2026 budget (excl. VAT) |
|---|---|---|
| Request form and routing | Sales enters the need, legal is notified | EUR 3,000 to 6,000 |
| Clause library | Approved clauses, variants by country and contract type | EUR 5,000 to 12,000 |
| Document generation | Word or PDF assembly from clauses and client data | EUR 4,000 to 9,000 |
| Version comparison | Highlights deviations from the approved template | EUR 4,000 to 10,000 |
| Approval flow | Legal, finance, management approval based on thresholds | EUR 3,000 to 8,000 |
| Signature integration (Yousign, Docusign) | Sending, reminders, retrieval of the signed file | EUR 3,000 to 7,000 |
| Archiving and renewal alerts | Secure vault, search, reminder 90 days before renewal | EUR 3,000 to 8,000 |
A minimal scope (request, templates, signature, archiving) sits around EUR 25,000 excl. VAT. A full scope with version comparison and threshold-based approval rules reaches EUR 60,000 excl. VAT.
Simple, advanced or qualified signature: what eIDAS says
The eIDAS framework (retained in UK law as UK eIDAS) defines three levels. The level you choose depends on the legal risk of the contract and drives the unit cost.
| eIDAS level | Identity check | Typical use | 2026 API cost (estimate) |
|---|---|---|---|
| Simple | Email and SMS code | NDAs, purchase orders, minor amendments | EUR 1 to 1.50 per signature |
| Advanced | Verified ID document, unique link to the signer | Franchise and commercial contracts | EUR 1.50 to 3 per signature |
| Qualified | Face to face or certified video, qualified certificate | High-stakes deeds, some public tenders | EUR 5 to 15 per signature |
| Yousign API subscription | Volume-based plan | SMEs and mid-caps | EUR 150 to 500 per month |
| Docusign API subscription | Prepaid annual envelopes | International groups | EUR 3,000 to 12,000 per year |
For a distribution network, the advanced signature covers most needs. With 1,100 contracts and 2.4 signers on average, the variable cost stays under EUR 8,000 a year.
Custom build or off-the-shelf CLM
| Criterion | Standard SaaS CLM | Custom workflow |
|---|---|---|
| Entry cost | EUR 0 to 10,000 setup | EUR 25,000 to 60,000 excl. VAT |
| Recurring cost | EUR 60 to 120 per user per month | EUR 300 to 800 per month (hosting, maintenance) |
| 3-year cost for 25 users | EUR 54,000 to 108,000 | EUR 36,000 to 89,000 |
| Fit with business clauses | Limited to built-in fields | Complete |
| ERP and CRM integration | Generic connectors | Custom |
| Data and code ownership | Vendor | Client |
Custom wins once you exceed 20 users and your contracts follow network-specific logic (territories, royalties, exclusivity).

Claire, general counsel of a 140-store retail network, handles 1,100 contracts a year with two lawyers. Each contract takes about 2.5 hours of chasing, version comparison and data entry. The custom workflow, quoted at EUR 42,000 excl. VAT, cuts this to 0.8 hours. Gain: 1,100 x 1.7 hours = 1,870 hours a year, about 1.2 full-time equivalents. At EUR 55 per loaded hour, that is EUR 102,850. After EUR 6,600 in signatures and EUR 6,000 in annual maintenance, payback comes in under six months. Signing time falls from 15 to 3 days, which speeds up new store openings.
FAQ
How long does it take to deliver a contract workflow?
Allow 10 to 16 weeks for a full scope, including 2 weeks of scoping with the legal team. A first version (templates and signature) can be live in 6 weeks.
Is an e-signature as valid as a handwritten one?
Yes, eIDAS and UK law recognise it, and the Electronic Communications Act 2000 admits it as evidence. An advanced signature strengthens proof in a dispute, for EUR 1.50 to 3 per signature.
Can we import our old signed contracts?
Yes, importing 3,000 to 10,000 documents with expiry-date extraction usually costs EUR 3,000 to 8,000 excl. VAT. Renewal alerts then work from day one.
Where is the data hosted?
We recommend UK or EU hosting, GDPR compliant, for EUR 150 to 400 a month. Signed files stay accessible even if you switch signature provider.
Will we have to change signature provider later?
The integration sits in its own module, so moving from Yousign to Docusign takes 1 to 2 weeks of development if pricing changes.
