How do you prevent your customer rows going back to 50 just started a couple months back.. adding more just last until next sign in

Good to see you here in the Community, @pat18. I can share some insight about setting the number of rows to default in QuickBooks Online (QBO).

I understand how saving the default number of rows on the customer's page will be more convenient for you while working with QuickBooks.

At this time, the option to set a default number of rows on the customers and vendors page is unavailable in QBO. For now, I'd recommend sending a feature request to our Product Development Team. This helps us improve your experience and the features of the program. 

Here's how:

1. Go to the Gear icon, then select Feedback.
2. Enter your suggestions, then select Next.
