Description
The QuickBooks Payments Gateway addon connects Event Espresso checkout to the organizer’s QuickBooks Payments account, processing participant credit cards directly on the registration page without redirecting to external sites. Capture happens via the QuickBooks Payments API, with immediate transaction status returned to Event Espresso, allowing event organizers to centralize registrations and charges in the same accounting environment already used for tax issuance and reconciliation.
