Integrating a Digital Membership Card CRM with QuickBooks Online

Hi everyone,

I’m currently working on a custom CRM that manages digital membership card, including member registration, renewals, and subscription tracking.

I would like to integrate it with QuickBooks Online so that:

• When a new member is added, a customer is automatically created in QuickBooks

• When a membership is purchased or renewed, an invoice is generated automatically

• Payment status updates back to the CRM

• Renewal reminders align with invoice due dates

Has anyone here implemented a similar integration?

I’m especially interested in understanding:

• Whether QuickBooks Online API supports smooth two-way sync

• Any common challenges with subscription-based billing

• Best practices for handling recurring memberships

I’d appreciate any guidance or documentation references from those who have experience with this.
