Platform

One platform for your entire procurement process.

From the Bill of Quantities (BoQ) to the sustainability report: comstruct brings all steps of your material procurement together on a single data basis - and the comstruct agents take over the work in between.

PURCHASING 

Based on your cost calculation, comstruct takes over purchasing. We group items by material category, send structured enquiries to the appropriate suppliers and automatically evaluate incoming quotations, regardless of the price format. The result: a clear price comparison at the touch of a button.
