Hi there, @Sarfz.
Thank you for reaching out to us here on the Community page. I can share with you some information about assigning GoCardless direct debit to customers.
Yes, the system only allows one GoCardless per customer. As a workaround, you can set the owner as a parent customer, and create the rest sub-customers and bill them with the parent one.
To create a parent customer:
- Open your QuickBooks Online account, then select Customers from the Sales tab.
- Click on Add customer manually or New customer.
- Fill in the necessary information, then click on the Save button.
For the sub-customers:
- Tap on New customer on the Customers window.
- Enter the customer's information.
- Mark the box beside the Is sub-customer section, select the parent customer and choose the Bill with parent option.
- Hit Save.
For additional resources about adding customers in QuickBooks Online, I recommend opening this link: How to add a customer.
Moreover, here are some of our help articles you can open to know more about GoCardless:
