Nium's Direct Debit funding capability helps you add your business customer's bank account to their Nium-issued wallet to help them make payments.
These are the requirements for this funding mechanism:
- Your customer needs to have a bank account and a Nium wallet.
- Your customer needs to authorize the Direct Debit mandate to debit from their bank account and accept Nium's terms and conditions (T&C).
- Your customer needs to have enough money in their added bank account to start your transactions.
- Your customer needs to be a business, also known as a corporation.
- Your customer needs to be onboarded to the Nium One platform.
Accept Nium’s T&C. Nium provides approval according to the geography where Direct Debit is set up. Nium then configures Direct Debit for self-funding to your customer's wallets. Once you complete these steps, you can use Direct Debit.
Direct Debit is a restricted functionality. As a new or existing client, contact a Nium sales representative to enable this functionality.
