Zyntra OS by Double Support

Contracting software for contractors in Germany

Zyntra Contracting runs a contractor’s projects from the bill of quantities to the last progress bill: what was measured, what was billed, what each subcontractor is owed and what is retained. For a company in Germany, Zyntra OS sends each invoice as a Peppol e-invoice on the European standard, keeps the books in euros, and is hosted in Europe.

Zyntra Contracting, the contracts: owner, project, period, value, certified and invoiced, and progress

A day for a contractor

The site engineer measures what was built this month. The office turns the measure into a progress bill against the bill of quantities, a subcontractor sends its own bill for its share of a line, and part of each bill is held back as retention until the work is handed over. In Zyntra Contracting a measured quantity can never go below the previous bill or above the bill of quantities, so nothing is billed twice and nothing beyond the contract.

For a company in Germany

Euros and European banks

Books in euros; bank accounts read through GoCardless or Salt Edge, or a statement file in MT940 or CAMT.053.

Payments: Mollie, Klarna, Adyen and Stripe

Your customer pays an invoice online by card through Mollie, Adyen or Stripe, or later with Klarna.
