I've tried to find this answer with no success. Is there a max amount that can be paid via an invoice? Max for ACH? Max for Credit Card?

Thank you for posting your concern here in the Community, DNO2. I'd like to provide you with valuable information about QuickBooks Payments processing limits and guide you to the appropriate support.

The account limit is unique to each merchant user, determined by QuickBooks based on your bank history and the number of online payments processed in the last 30 days, depending on your customers' processing volume.

Certain users have standard daily and monthly payment limits. Once reached, customers won't be able to make online payments unless the limits are restored within the 30-day rolling window.

While the Community space is unable to look into your account, I'd recommend getting in touch with our payment support team for detailed information on processing limits.

Here's how:

1. Go to the Help icon and choose Search.
2. Click the Contact Us button and enter your concern.
3. Press Continue.

Furthermore, you can access and manage your QuickBooks Payments to track transactions and update your information when necessary.

To learn more about the acceptable use guidelines and terms and conditions for the QuickBooks Payments Service, you may want to read the Intuit Payments Merchant Agreement and the Intuit Payments Inc. Acceptable Use Policy.

Please don't hesitate to ask if you have further inquiries about QuickBooks Payments or need assistance with any specific task. I'm here to help at all times.
