Platform

How to make your material procurement competitive with agents.

One process, one data foundation - from the Bill of Quantities (BoQ) to the sustainability report. Your cost calculation remains your competitive advantage, the comstruct agents handle everything after that.

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 enquiries to the appropriate suppliers.

03

Quote comparison & negotiation

comstruct evaluates the quotes, compares prices transparently and negotiates the best terms, comparable figures instead of inconsistent PDFs.

Calculate the benefit of better terms
04

Master agreement & release

The negotiated framework agreements are held centrally on the platform. Your team releases material directly at the agreed terms, no outdated price lists.

Calculate savings per release
05

Digital delivery tickets

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

Calculate hours per delivery ticket
06

INVOICE MATCHING

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

Calculate savings per invoice
07

Sustainability reporting

comstruct analyses your consumption volumes, the data foundation for your sustainability reporting is created automatically from the ongoing process.

"Invoice matching and approval used to take two to three hours every day because of the large number of invoices. Today, thanks to comstruct, it only takes minutes."
