Digital management of subcontractor certificates

Certificates are legally required documents that subcontractors must submit before starting work. These include, for example, the A1 certificate for social insurance, the exemption certificate to avoid construction withholding tax and the clearance certificate from the tax office. Without these documents, many subcontractors are not allowed to work on the construction site.

The most important proofs for subcontractors are:
- A1 certificate (confirmation of social security obligation)
- certificate of exemption (avoidance of 15% construction withholding tax)
- clearance certificate from the tax office
- public liability insurance
