How it works
From a pile of tender docs to a signed bid — in five steps.
This is what working a tender in Steinlog looks like, start to finish. No training, no sales call — you do it yourself, and what comes out is a real, submission-ready package.

Understand it in minutes
Ask X-Ray anything — requirements, deadlines, the signature tier — and get answers cited to the exact clause.
Yes. Above the EU threshold the offer and the ESPD must carry a qualified signature (QES); an advanced signature (AdES) is rejected, and the defect cannot be cured.
Price it — your numbers
The bill of quantities is laid out and drafted. You set every binding price: the AI proposes, you own.

Check what blocks submission
The gate computes a single GO / NO-GO and lists exactly what's missing — so you can't submit an incomplete bid.
- Block Signature tier: QES required (SWZ §7.2) — current: AdES
- Block Per-partner ESPD missing for Partner B
- Block Bill of quantities: 2 lines unpriced
- Clear Addendum 2 acknowledged
- Clear ASiC-E manifest ready to seal
