GAEB interface: bill of quantities in, priced answer out
GAEB is the standard German tenders and bids are exchanged in. KraftHub reads the tender's bill of quantities, prices the items with AI support from your own prices and past projects, and writes the priced answer back as a GAEB file — X84 Angebotsabgabe or X86 Auftragserteilung, with broken-out unit-price components where the tender asks for them.
How you know you need it
Bills of quantities get exported to Excel and priced there.
The answer to the awarding body is assembled by hand.
Tenders with four-figure item counts block costing for days.
A bid is rejected over a formal defect in the file.
Unit-price components are demanded and do not add back up to the unit price.
