Yes - Tenera can be connected to existing ERP, project management or DMS systems via our API.

Yes - in addition to certificate management, Tenera also offers a project management module that has been specially developed for construction practice. This enables general contractors to structure their projects and create and manage orders.

In the project management module, missing or expired certificates can be automatically identified at order level and the associated risk assessed. In addition, the integrated supplement management enables clients to record, track and document all supplements for their projects centrally.

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

Missing or invalid certificates can lead to additional payments, fines of up to €30,000, assumption of liability or even construction stoppages.

Yes - subcontractors automatically receive an upload link from Tenera and are reminded to upload missing or soon to be invalid proofs; alternatively, proofs can also be uploaded manually by the purchasing department, e.g. if documents are received by other means (e-mail, post, etc.).

This depends on the type of document. Many documents are valid for 6 to 12 months. Tenera automatically reminds you of upcoming deadlines.

Yes - e.g. in accordance with § 48 EStG (construction withholding tax) and § 28e SGB IV (social security certificates). Missing documentation can have legal and financial consequences.
