Understand it in minutes
Ask X-Ray anything — requirements, deadlines, the signature tier — and get answers cited to the exact clause. The bill of quantities is laid out, ready to price.
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 together — your numbers
Your team prices the bill of quantities in one room: the AI proposes, you own every binding price. Every change is attributed, append-only — rewind to any version.

Check what blocks submission
The readiness check 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
