The $25,000 ACH transaction limit in QuickBooks Online cannot be overridden, Alva2582.

This limit is primarily in place for security and risk management purposes set by QuickBooks Payments. However, you can request an increase to your ACH limit by contacting the QB Payments support team.

Alternatively, you can explore other payment methods using the App feature or wait for the limit to reset within 30 days if you've reached the ACH cap. For more information, refer to this article: Learn about QuickBooks Bill Pay.

Contact us anytime if you have more questions bout ACH payment.

how did you get a resolution here? I am having the same issue and I have been on the phone with support for at least 12+ hours - the limitations of the service is ridiculous.
