Live Demo: Try this and other plugins live — no installation, no risk: demo.markus-michalski.net
¶ Important notice
This plugin is NOT a payment provider. It captures and manages SEPA mandates but does not collect any amounts.
The plugin does not do the following:
- No automatic debiting: There is no export of a SEPA file and no bank connection. You submit the direct debits to your bank yourself.
- No risk or credit check: There is neither fraud detection nor scoring.
- No payment guarantee: Chargebacks are possible. The plugin does not know them and does not change the order's payment status.
It suits merchants who already have their own bank access for direct debit collection and want to map mandate management in Shopware.
¶ Overview
The plugin adds the payment method SEPA Direct Debit to Shopware. At checkout customers enter IBAN, account holder and their consent to the mandate. The plugin validates the data, stores the IBAN encrypted, generates a mandate reference and provides a mandate PDF. You see all mandates in the admin and collect the amounts outside the plugin through your bank.
