Audit-Ready,
Before Arrival.
Scope the Evidence Pack Six-Axis Verification Per Worker
Identity and right-to-work documentation; A1 portable certificate or third-country residence pathway; trade qualification verified against destination-country standards; collective-agreement classification mapped to the correct sectoral table; tax and pension currency; sending-undertaking registration. Six axes, one bundle, one worker.
URSSAF Solidarité Financière Discharge
Under Décret 2025-1338, URSSAF accepts a complete, verifiable documentation pack on each sub-tier worker as a full defence to the cascade. The pack is assembled to discharge specification before deployment, not reconstructed during the audit. Six-monthly verification cycle of attestation, registration and A1 maintained for the deployment lifetime.
Triple-Purpose Documentation
The same per-worker pack discharges the URSSAF cascade, populates the CSRD ESRS S2 value-chain workforce disclosure for listed parents, and satisfies the Plan de Vigilance evidence requirement under Loi 2017-399. One file, three regulatory regimes. The contractor maintains one source of truth, not three.
Trade-Specific Qualification Mapping
EN ISO 9606-1 welder qualifications cross-checked against the WPS scope on the receiving site. EN 1090 EXC3 / EXC4 execution-class certification mapped to the lot specification. NF C 18-510 habilitation pathway pre-cleared. DIN VDE 1000-10 Elektrofachkraft status documented through Gesellenbrief equivalency and experience verification. Generic certification is not evidence; scope-matched verification is.
Retrievable in 48 Hours, Per Worker, Per Site
Inspectors do not request paper. They request structured electronic evidence retrievable across an entire portfolio in 48 hours. The pack is stored in the format the inspector expects — indexed by worker, by site, by date, by regulatory pillar — so a portfolio-wide demand surfaces no gaps.
Why the Conventional Approach Fails
| Documentation Reconstructed Post-Hoc | Pack Assembled Pre-Deployment | |
|---|---|---|
| Trigger Timing | Documentation gathered after audit notice; counsel and HR teams scramble to locate records held across multiple sub-tier suppliers. | Pack assembled at T-90 days before mobilisation; complete and inspector-ready at T-0. |
| URSSAF Defence | Reliance on sub-tier assertions of compliance; principal contractor exposed to retroactive cascade over five years. | Documented six-monthly verification cycle — vigilance attestation, registration, A1, equal-treatment evidence — accepted by URSSAF as full discharge. |
| CSRD ESRS S2 Input | Value-chain workforce disclosure assembled annually from incomplete sub-tier records; auditor flags coverage gaps. | Pack populates the ESRS S2 value-chain workforce disclosure directly; auditor traces every worker to source documentation. |
| Qualification Scope Match | Generic certification accepted; scope-mismatch with WPS or execution-class surfaces during commissioning. | Every qualification scope-matched against the lot specification before mobilisation; no commissioning-stage rejections. |
