Zyntra OS by Double Support

Appointment booking software for businesses in Germany

Zyntra Appointments books a business’s visits on a calendar that never books a time twice, with deposits and packages that post and reverse themselves in the books. 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 Appointments, the overview: today, tomorrow, to confirm, the waiting list, revenue, the no-show rate, today's appointments and appointments per day

A day of appointments

A client books online, another calls the desk, a third uses a visit from a package. One cancels and later asks to come back after all. In Zyntra Appointments bringing back a cancelled visit checks the time again, a cancel gives back the package visit and the coupon use and voids the unpaid deposit invoice, and a group class never takes a party larger than the seats left.

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.

Hosted in Europe

Zyntra OS is hosted in Europe, and we sign a Data Processing Agreement with every European client.
