The verdict in three sentences
An engineering school processing 1,500 internship agreements and several hundred apprenticeship contracts a year without a dedicated tool ties up the equivalent of 3 full-time administrative staff on chasing and re-keying. A custom web app connected to the student information system, with e-signature of agreements and supervisor tracking, costs 30,000 to 65,000 EUR excl. VAT (about 32,000 to 70,000 USD) and ships in 4 months. It pays off as soon as the standard modules of your student information system cannot match your real approval workflows.
What breaks in internship management in 2026
The corporate relations manager of a 2,000-student school lives through three peaks a year: second-year internships, final-year placements and the intake of apprentices. Each peak brings the same friction. The student fills in a form, the company sends back an edited version, the academic supervisor approves by email, the director of studies signs a scanned PDF. An agreement goes through 4 people and 6 round trips on average.
Apprenticeships add their own obligations: Cerfa contracts, filing with the OPCO training fund, tracking school and company rhythms, three-way reviews. Without a tool, delays cost internships starting without a signed agreement, which exposes the school if an accident happens, and late OPCO funding.
2026 budget for an internship management app
Here is the 2026 order of magnitude for a school with 2,000 students, 1,500 agreements and 400 apprentices a year.
| Module | Scope | 2026 budget (EUR excl. VAT) |
|---|---|---|
| Scoping and user journeys | Student, company, supervisor, director of studies | 3,000 to 6,000 |
| Agreement entry and generation | Legal template, clauses per degree, calculated stipend | 6,000 to 12,000 |
| E-signature | 3 or 4 signatories, timestamping, archiving | 3,000 to 7,000 |
| Company portal and job offers | Offer posting, applications, partner database | 5,000 to 11,000 |
| Supervisor tracking and assessments | Visits, assessment grids, defences | 4,000 to 9,000 |
| Apprenticeship module | Contracts, rhythms, OPCO deadlines, three-way reviews | 4,000 to 10,000 |
| Student information system connector | Student import, internship grade export | 3,000 to 7,000 |
| Dashboards and acceptance | Placement rate, lead times, surveys | 2,000 to 3,000 |
| Total | Timeline: 4 months | 30,000 to 65,000 |
Then budget 300 to 700 EUR excl. VAT per month for French hosting and maintenance, plus the unit cost of e-signature, usually 0.50 to 1.50 EUR per envelope depending on volume, or 750 to 2,250 EUR a year for 1,500 agreements.
Custom build or student information system module
Most student information systems offer an internship module. The real question is whether it fits your internal rules or forces you to work around them.
| Criterion | Student information system module | Custom application |
|---|---|---|
| Initial cost | 5,000 to 15,000 EUR of configuration | 30,000 to 65,000 EUR excl. VAT |
| Recurring cost | 3 to 8 EUR per student per year, i.e. 6,000 to 16,000 EUR | 3,600 to 8,400 EUR per year |
| Specific approval workflows | Configurable within limits | Exactly your rules |
| Built-in e-signature | Varies, sometimes a paid option | Included in scope |
| Company and supervisor experience | Often dated | Designed for mobile |
| Apprenticeship and OPCO tracking | Rarely complete | Dedicated module |
| Code ownership | No | Yes |
Over 5 years, the vendor module costs about 35,000 to 95,000 EUR, against 48,000 to 107,000 EUR for custom. The amounts are close: the decision hinges on fit with real workflows and on the experience of partner companies, which drives how many offers you receive.

Nathalie, corporate relations manager at an engineering school in Lille, runs a team of 5. She estimates that 3 FTEs go into data entry, chasing and filing agreements. Fully loaded cost of an administrative FTE: about 42,000 EUR a year, so 126,000 EUR for these tasks.
After a 52,000 EUR excl. VAT app delivered in 4 months, students do the data entry, reminders go out automatically and e-signature removes printing. The team reallocates 2.5 FTEs to developing company partnerships. Capacity gain: 105,000 EUR a year, for a recurring cost of about 8,000 EUR. The project pays back in under 7 months, and the average time to sign an agreement drops from 18 to 5 days.
FAQ
Is an e-signed internship agreement legally valid?
Yes, a simple or advanced electronic signature compliant with eIDAS is enough for an internship agreement. It costs 0.50 to 1.50 EUR per agreement depending on the provider.
Can students be pulled automatically from our student information system?
Yes, through an API or a scheduled export. The connector costs 3,000 to 7,000 EUR excl. VAT and syncs students, cohorts and supervisors every night.
Does the app handle apprenticeship contracts and the OPCO?
The apprenticeship module tracks contracts, filing deadlines and rhythms. It costs 4,000 to 10,000 EUR excl. VAT depending on the number of OPCOs and formats.
Where is student data hosted?
In France, with a certified host and retention aligned with GDPR. Hosting runs at about 150 to 400 EUR excl. VAT per month.
How long before the first internship campaign goes live?
The full project takes 4 months. Agreements and e-signature can go live in month 3 so you do not miss a placement peak.
