Construction procurement knowledge
Key terms in construction purchasing, invoice verification and tendering explained, from four-way matching and Skonto to Germany's 2027 e-invoicing mandate.
Material spend is one of the largest costs on every construction site, and one of the least controlled. These articles explain the terms and processes that matter in building-material procurement: how to verify invoices properly, make bids comparable, capture early-payment discounts and prepare for mandatory e-invoicing.
To see how Streckenheld automates these processes day to day, read our guides.
What a four-way match is, how it differs from two- and three-way matching, and which deviations are typical on building-material invoices, with an example.
What a bid comparison (Preisspiegel) is, how to build one for material tenders, normalise units, rate alternative bids and award on total cost, with an example.
What maverick buying is, why it is so common on construction sites, what it costs, and how construction firms can measure and reduce their maverick buying rate.
Early-payment discount (Skonto) explained: typical terms, the effective annual interest formula with a worked example, and why construction firms miss it.
Germany's B2B e-invoicing mandate: deadlines, the €800,000 threshold, XRechnung and ZUGFeRD, reverse-charge and progress invoices, plus a checklist.
