Platform

How you set up your material procurement competitively with agents.

One process, one data foundation — from the bill of quantities to the sustainability report. Your calculation remains your competitive advantage; everything after that is handled by the comstruct agents.

01
Stays with you

Bill of Quantities

You receive the BoQ and calculate your target prices. That is your core competency and it stays that way.

02

Tendering

You upload your BoQ, comstruct automatically groups the line items by material category and proposes structured requests to the right suppliers.

03

Quote Comparison & Negotiation

comstruct evaluates the quotes, compares prices transparently on line-item level and negotiates the best conditions — comparable numbers instead of inconsistent PDFs.

04

Framework Agreement & Call-Off

The negotiated master agreements sit centrally on the platform. Your team calls off material directly at the agreed conditions — no outdated price lists.

05

Digital Delivery Tickets

Delivered materials are captured digitally at the supplier or via batch scan — complete and GoBD-compliant.

06

INVOICE MATCHING

AI account assignment and automatic reconciliation of invoices against BoQ, master agreement and delivery ticket. You only pay for what was ordered, delivered and agreed.

07

Sustainability Reporting

comstruct analyzes your consumption volumes — the data basis for your sustainability reporting is created automatically from the ongoing process.
