I understand the value of your time, especially when managing the day-to-day financial tasks for your business, @DARLA14. QuickBooks Online is designed to accommodate a variety of payment methods, and one of the ways it maintains accuracy in your records is by including a check number field.
Currently, QBO does not automatically hide or clear the check number field when recording ACH payments. This means you do need to manually remove or clear that number each time you choose ACH as the payment type.
If this is a feature you feel strongly about, I recommend submitting feedback directly to our Product Engineers. They review customer suggestions for future updates. Here's how:
- Go to the Gear icon and select Feedback.
- Enter your comments or product suggestions.
- Then select Next to submit feedback.

I hope this explanation helps clarify why the check number field behaves as it does in QBO. I know it’s a small but important detail that affects your day-to-day workflow, and I truly appreciate your patience as you manage this step manually for now. Take care!
