Unzer

German full-stack payment provider for online and in-store

Germany, Berlin Founded 2003 unzer.com ↗ Non-EU parent: KKR (US)

Unzer (formerly Heidelpay) is a German payment service provider offering online payments, BNPL (invoice, instalments, direct debit) and POS terminals including the Android-based POS Go device, with dedicated bundles for gastronomy and retail. It serves more than 90,000 merchants, mainly in the DACH region, and integrates with Shopware, Shopify, Magento and OXID. KKR bought the group in 2019 and later handed majority control to creditors after a refinancing.

Our reading. Best for DACH retailers on Shopware, Shopify or Magento that want online, BNPL and in-store payments from one German provider and are willing to negotiate a quote.
